<h2 id="v44_introduction">Introduction</h2>
<p>Welcome to [% terms.Bugzilla %] 4.4! It has been over a year since we
released [% terms.Bugzilla %] 4.2 on February 2012, and this new major
release comes with several new features and improvements. This release
contains major improvements to WebServices, which were our main target in
this release, a rewritten tagging system, a real MIME type auto-detection for
attachments, improved support for Oracle, performance improvements and lots
of other enhancements.</p>
<p>If you're upgrading, make sure to read <a href="#v44_upgrading">Notes On
Upgrading From a Previous Version</a>. If you are upgrading from a release
before 4.2, make sure to read the release notes for all the
<a href="#v44_previous">previous versions</a> in between your version and
this one, <strong>particularly the Upgrading section of each version's
release notes</strong>.</p>
<h2 id="v44_point">Updates in this 4.4.x Release</h2>
<h3>4.4.1</h3>
<p>This release fixes several security issues. See the
<a href="http://www.bugzilla.org/security/4.0.10/">Security Advisory</a>
for details.</p>
<p>In addition, the following [% terms.bugs %] have been fixed in this release:</p>
<ul>
<li><kbd>checksetup.pl</kbd> no longer fails with "Invalid version format (non-numeric data)"
when a Perl module contains an invalid version number.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=781672">[% terms.Bug %] 781672</a>)</li>
<li>Internet Explorer 11 and KHTML-based browsers such as Konqueror can now
display buglists correctly.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=902515">[% terms.Bug %] 902515</a> and
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=914262">[% terms.bug %] 914262</a>)</li>
<li>When editing several [% terms.bugs %] at once and moving them into a new
product, [% terms.bugs %] restricted to a group in the old product could
loose these group restrictions in the new product.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=769134">[% terms.Bug %] 769134</a>)</li>
<li>When the <kbd>password_complexity</kbd> parameter was set to
'letters_numbers_specialchars', passwords containing numbers and special
characters only were accepted. Now it makes sure that a letter is also present.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=897264">[% terms.Bug %] 897264</a>)</li>
<li>Large dependency trees are now displayed much faster.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=917370">[% terms.Bug %] 917370</a>)</li>
<li>When a user has set many votes, the "Votes" page is now displayed much faster.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=851267">[% terms.Bug %] 851267</a>)</li>
<li>The "My Requests" page now correctly uses the AND/OR operator for the
requester and requestee fields only instead of using it for all fields.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=891311">[% terms.Bug %] 891311</a>)</li>
<li>With DB servers doing case-insensitive comparisons, such as MySQL, tokens
and login cookies were not correctly validated as the case was ignored.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=906745">[% terms.Bug %] 906745</a> and
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=907438">[% terms.bug %] 907438</a>)</li>
<li>All security headers (such as X-Frame-Options) are now returned when using XML-RPC.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=787328">[% terms.Bug %] 787328</a>)</li>
<li>Oracle crashed when reporting a new [% terms.bug %] if a custom free-text field
was non-mandatory and left empty.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=919475">[% terms.Bug %] 919475</a>)</li>
<li>It was not possible to import [% terms.bugs %] using <kbd>importxml.pl</kbd> with Oracle.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=848063">[% terms.Bug %] 848063</a>)</li>

<h3 id="v44_req_apache">Optional Apache Modules</h3>
<p>If you are using Apache as your webserver, [% terms.Bugzilla %] can
take advantage of some Apache features if you have the below Apache
modules installed and enabled. Currently,
<a href="#v40_feat_js_css_update">certain [% terms.Bugzilla %] features</a>
are enabled only if you have all of the following modules installed
and enabled:</p>
<ul>
<li>mod_headers</li>
<li>mod_expires</li>
<li>mod_env</li>
</ul>
<p>On most systems (but not on Windows), <kbd>checksetup.pl</kbd> is able to
tell whether or not you have these modules installed, and it will tell
you.</p>
<h2 id="v44_feat">New Features and Improvements</h2>
<ul>
<li><a href="#v44_feat_search">Allow Multiple Search Criteria to Match one Field</a></li>
<li><a href="#v44_feat_search_perf">Improved Performance for Searches</a></li>
<li><a href="#v44_feat_bug_tags">Overhaul of the Tagging System</a></li>

<li><a href="#v44_feat_other">Other Enhancements and Changes</a></li>
</ul>
<h3 id="v44_feat_search">Allow Multiple Search Criteria to Match one Field</h3>
<p>
In the "Advanced Search" page, it is now possible to build queries using
multiple custom search criteria against the same field. In [% terms.Bugzilla %]
4.2 and older, queries of the form
<br><br>
<kbd>"Status changed to VERIFIED" AND "Status changed by foo@bar.com"</kbd>
<br><br>
were returning all [% terms.bugs %] which had their status changed to VERIFIED
by some user and which were edited by foo@bar.com once, but both actions could
be independent. In [% terms.Bugzilla %] 4.4, you can now decide if both
criteria must match the exact same action or not, i.e. if you want
[%+ terms.bugs %] whose status has been set to VERIFIED by foo@bar.com himself.
In the same way, queries of the form
<br><br>
<kbd>"Flags changed to approval+" AND "Flags changed by foo@bar.com"</kbd>
<br><br>
can now return [% terms.bugs %] for which the approval flag has been set to
"+" by foo@bar.com himself. In previous versions, both actions were treated
independently and [% terms.bugs %] for which foo@bar.com set the approval flag
to "?" and which is then set to "+" by someone else were also returned.
</p>
<p>
This new feature gives you the ability to build more accurate queries and to
get more relevant results.
</p>
<h3 id="v44_feat_search_perf">Improved Performance for Searches</h3>
<p>
The search system got a performance boost which in some cases decreases the
time spent to run queries from several minutes to a few seconds only.
The more complex your queries are, the more visible the performance win
should be.
</p>
<h3 id="v44_feat_bug_tags">Overhaul of the Tagging System</h3>
<p>
The old tagging system which was in the footer of all pages had severe design
and usability limitations and has been replaced by a shiny new one which lets
you tag [% terms.bugs %] from the [% terms.bug %] report directly. Tags now
mostly work like keywords, but with two major differences. First of all, they
are personal, meaning that tags you set on [% terms.bugs %] are only visible
by you, and nobody else is notified nor can see which tags you set. This
behavior is the same as the old tagging system and so this feature didn't
change. The second major difference is that the list of available tags is
unlimited and is in no way hardcoded by administrators. You can type either
a new tag of your choice, or you can select one from an auto-generated list
of tags which you already used in other [% terms.bugs %]. Again, this feature
was already present in the old tagging system, but its usability has been
greatly improved. In particular, this means that tags are now displayed in
[%+ terms.bug %] reports directly, so that you immediately know which tags
you already set for that [% terms.bug %]. This feature is new in this release.
</p>
<p>
Another new feature is that your personal tags can now be listed in buglists.
They can also be used as search criteria in your queries. If you decide to
share a saved search which uses tags as criteria, this will work too! Note
that when you add a new tag, no saved search based on this tag is created
anymore, as you can easily create it yourself if you really need it.
</p>
<p>
The tags set with the old tagging system are automatically migrated to the
new system.
</p>
<h3 id="v44_feat_mimetype_autodetect">Auto-Detection of the Attachment MIME Type</h3>
<p>
When a user uploads a new attachment and lets the "Content Type" field set to
"auto-detect", [% terms.Bugzilla %] now does its own MIME type detection
if the web browser tells him that the attachment is of type
"application/octet-stream", in an attempt to make a better guess than the web
browser. In all other cases, [% terms.Bugzilla %] still trusts what the browser
tells him.
</p>
<p>
Check the <a href="#v44_req_optional_mod">list of optional Perl modules</a> to
know which modules to install in order to enable MIME type sniffing.
</p>
<h3 id="v44_feat_saved_reports">Saving Tabular and Graphical Reports</h3>
<p>
It is now possible to save tabular and graphical reports in the same way as
you save searches. Saved reports will appear in the footer of pages, below
saved searches.
</p>
<p>
Unlike saved searches, it is not yet possible to share saved reports with
other users.
</p>
<h3 id="v44_feat_whining">Custom Columns in Whine Emails</h3>
<p>
The list of columns to display in buglists contained in emails sent by the
whining system on a regular basis is no longer hardcoded. If the saved
search used for whining emails contains a list of columns, these columns are
used to be displayed in the emails. If no custom list is found, the default
column list is used instead.
</p>
<p>
This means that depending on the kind of email notifications you want, you
can fully customize data to return, on a per saved search basis!
</p>
<h3 id="v44_feat_webservices">Improved WebServices</h3>
<p>
This release got major improvements in its WebServices interface. Many new
methods have been implemented to let third-party applications interact with
[%+ terms.Bugzilla %] even more closely. For instance, it is now possible to
know what parameters are set to using <kbd>B[%%]ugzilla.parameters</kbd>.
It is now also possible to update tags, products, groups or user accounts
using our API.
<p>
<p>
Several existing methods have also been improved to return data which
weren't available till now, such as [% terms.bug %] and attachment flags
using <kbd>B[%%]ug.get</kbd>, <kbd>B[%%]ug.attachments</kbd> or
<kbd>Product.get</kbd>. Users can also get their saved searches and reports
using <kbd>User.get</kbd>; and much more, see the
<a href="#v44_feat_webservices_details">detailed list</a> below.
</p>
<h3 id="v44_feat_apache_config">New Apache Configuration</h3>
<p>
For improved security, [% terms.Bugzilla %] now prevents directory browsing
by default. If you run [% terms.Bugzilla %] under Apache (as most people do),
you most likely require a <strong>new Apache configuration</strong> for this
version of [% terms.Bugzilla %]. See the
<a href="#v44_upgrading">Notes On Upgrading From a Previous Version</a>
section for details.
</p>
<h3 id="v44_feat_other">Other Enhancements and Changes</h3>
<h4>Enhancements for Users</h4>
<ul>
<li><strong>[% terms.Bugs %]:</strong> It is now possible to add yourself to
the CC list when uploading an attachment and when editing an existing one.</li>
<li><strong>[% terms.Bugs %]:</strong> There is a new user preference to be
automatically added to the CC list of [% terms.bugs %] for which a flag
request is addressed to you (the flag has you as the requestee).</li>
<li><strong>[% terms.Bugs %]:</strong> Changes to the CC list no longer
causes midair collisions.</li>
<li><strong>[% terms.Bugs %]:</strong> There is now a <em>(take)</em> link
besides the QA Contact field to easily set yourself as QA contact.</li>
<li><strong>[% terms.Bugs %]:</strong> [% terms.Bugs %] are no longer
reassigned to the default assignee when moving the [% terms.bug %] into
another product or component if the current assignee is not the default
one. Same goes for the QA contact.</li>
<li><strong>[% terms.Bugs %]:</strong> When reporting a new [% terms.bug %],
flags which are not available for the selected component and those which
the reporter cannot edit are now hidden instead of being disabled. For
existing [% terms.bugs %], unset flags are also hidden by default. Clicking
the <em>(set flags)</em> or <em>(more flags)</em> link will make them
appear.</li>
<li><strong>[% terms.Bugs %]:</strong> When viewing [% terms.abug %], the list
of duplicated [% terms.bugs %] is now listed near the top of the page.</li>
<li><strong>[% terms.Bugs %]:</strong> Private comments now always remain
visible to their author. Previously, the author of a comment couldn't see
it anymore if the comment was marked private and the author isn't in the
insider group.</li>
<li><strong>[% terms.Bugs %]:</strong> The See Also field now supports URLs
pointing to GitHub by default. If the new MoreBugUrl extension included in
this release is enabled, then you can also add URLs pointing to:
b[%%]ugs.php.net, RT, appspot.com (Rietveld), Review Board, and
getsatisfaction.com.</li>
<li><strong>Searches:</strong> The alias of [% terms.bugs %] you cannot see
are no longer resolved to their [% terms.bug %] ID, meaning that it is no
longer possible to connect an alias with its ID unless you can see the
[%+ terms.bug %].</li>
<li><strong>Searches:</strong> Custom multi-select fields are now available
in the "Search By Change History" section of the query page.</li>
<li><strong>Searches:</strong> The <em>changed by</em> operator in boolean
charts now accepts pronouns.</li>

queries appearing at the top of buglists.</li>
<li><strong>Requests:</strong> The "My Requests" page now displays an AND/OR
radio button to define the interaction between the requester and requestee
fields.</li>
<li><strong>Email Notifications:</strong> There is a new user preference to
not prepend "New:" to the subject of [% terms.bug %]mails when reporting
a new [% terms.bug %]. Some email clients couldn't thread emails correctly
due to this.</li>
<li><strong>Email Notifications:</strong> There is a new email event to get
notifications when the product or component of [% terms.abug %] changes.</li>
<li><strong>Email Notifications:</strong> All [% terms.bug %]mails now have
a <em>X-Bugzilla-Flags</em> email header, listing currently set flags.</li>
<li><strong>Email Notifications:</strong> All [% terms.bug %]mails now have
a <em>X-Bugzilla-Version</em> email header with the current product
version.</li>
<li><strong>Whining:</strong> The sort order of the saved search is used to
sort [% terms.bugs %] in the emails.</li>
<li><strong>User Accounts:</strong> To confirm an email address change, the
password is now requested instead of the old email address.</li>
<li><strong>Graphical Reports:</strong> The size of graphical reports is now
set dynamically to fit within the window of the web browser.
The Taller/Thinner/Fatter/Shorter links are now gone.</li>
<li><strong>Incoming Emails:</strong> <kbd>email_in.pl</kbd> now accepts
HTML-only emails to create and edit [% terms.bugs %] by email.</li>
<li><strong>Incoming Emails:</strong> When creating a new [% terms.bug %],
<kbd>email_in.pl</kbd> will look at the <em>Importance</em> and
<em>X-Priority</em> email headers to increase or decrease the initial
priority of the [% terms.bug %], unless the priority is already explicitly
set in the email itself.</li>
<li><strong>Skins:</strong> [% terms.Bugzilla %] no longer fetches all skins
available when viewing a page. It only loads the skin selected by the user
in his preferences, which results in less requests to the server.</li>
</ul>
<h4>Enhancements for Administrators and Developers</h4>
<ul>
<li><strong>License:</strong> The [% terms.Bugzilla %] code is now released
under the MPL 2.0 license (previously was MPL 1.1).</li>
<li><strong>Installation:</strong> On mod_perl, templates now remain in
memory for one hour, which can cause an increase in memory requirements.
This also means that it can take up to one hour before changes in templates
become active (unless you restart Apache).</li>
<li><strong>Installation:</strong> Running
<kbd>checksetup.pl --make-admin=foo@bar.com</kbd> now automatically
re-enables the user account if it was disabled.</li>
<li><strong>Configuration:</strong> A new parameter <em>smtp_ssl</em> can be
turned on to enable SSL connections to the SMTP server to send email
notifications.</li>

about. This description then appears as a tooltip when hovering the custom
field in [% terms.bug %] reports.</li>
<li><strong>Administration:</strong> When creating a new product, the form
lets you add a component at the same time.</li>
<li><strong>Administration:</strong> When viewing a user account in

who did not log in since you upgraded to 4.4 will have this field empty.</li>
<li><strong>Administration:</strong> It is now possible to exclude disabled
user accounts when running a query in <kbd>editusers.cgi</kbd>.</li>
<li><strong>Administration:</strong> The default CC list is now also displayed
when listing components in <kbd>editcomponents.cgi</kbd>.</li>
<li><strong>Administration:</strong> Target milestones can now be 64 characters
long, for consistency with versions (previously was limited to 20 characters
only).</li>
<li><strong>Administration:</strong> The result code returned by
<kbd>contrib/bugzilla-queue.rhel</kbd> when it's not running is now 2
instead of 0.</li>
<li><strong>Database:</strong> Support for MySQL 5.6 has been added.</li>
<li><strong>Database:</strong> Support for Oracle has been greatly improved.</li>
<li><strong>Security:</strong> For improved security, the
"X-Content-Type-Options: nosniff" and "X-XSS-Protection: block"
headers are now sent with every response.</li>
<li><strong>Security:</strong> Tokens are now generated using HMAC SHA-256
instead of MD5.</li>
<li><strong>Documentation:</strong> The documentation is now generated with
<kbd>xmlto</kbd> and <kbd>dblatex</kbd> instead of <kbd>jade</kbd>.</li>
</ul>
<h4 id="v44_feat_webservices_details">WebService Changes</h4>
<ul>
<li>Several new methods have been added: <kbd>B[%%]ug.update_tags</kbd>,
<kbd>B[%%]ugzilla.parameters</kbd>, <kbd>B[%%]ugzilla.last_audit_time</kbd>,
<kbd>Classification.get</kbd>, <kbd>Group.update</kbd>,
<kbd>Product.update</kbd>, <kbd>User.update</kbd>.</li>
<li><kbd>B[%%]ug.add_attachment</kbd> now only returns the ID of the newly
created attachments instead of all the attachment data.</li>
<li><kbd>B[%%]ug.attachments</kbd> now also returns the <kbd>size</kbd> field
containing the size of the attachment.</li>
<li><kbd>B[%%]ug.attachments</kbd> and <kbd>B[%%]ug.get</kbd> now return
data about flags.</li>
<li><kbd>B[%%]ug.comments</kbd> now also returns <kbd>creation_time</kbd>
which is exactly the same as <kbd>time</kbd>, but is provided for
consistency with <kbd>B[%%]ug.get</kbd> and <kbd>B[%%]ug.attachments</kbd>.
The <kbd>time</kbd> field may be deprecated and removed in a future release,
so you should use <kbd>creation_time</kbd> instead.</li>
<li><kbd>B[%%]ug.comments</kbd> now also returns the <kbd>count</kbd> field
containing the comment ID relative to the [% terms.bug %] it belongs to.
This is the same comment ID as the one you can see in [% terms.bug %]
reports.</li>
<li>It is now possible to create new [% terms.bugs %] with a closed status with
<kbd>B[%%]ug.create</kbd>.</li>
<li>The <kbd>bug_status</kbd> field returned by <kbd>B[%%]ug.fields</kbd> now
also includes [% terms.bug %] statuses available on [% terms.bug %] creation.</li>
<li><kbd>B[%%]ug.fields</kbd> now also returns keyword descriptions, not only
their names.</li>
<li><kbd>B[%%]ug.fields</kbd> now also returns the <kbd>is_active</kbd> field
for product-specific fields.</li>
<li>For users in the timetracking group, <kbd>B[%%]ug.get</kbd> now also
returns the <kbd>actual_time</kbd> field with the total number of hours
spent in the [% terms.bug %].</li>
<li>Field names returned in the <kbd>field_name</kbd> field of the
<kbd>B[%%]ug.history</kbd> method have changed to be consistent with other
methods.</li>
<li>The <kbd>B[%%]ug.search</kbd> method was returning all visible [% terms.bugs %]
when called with no arguments, ignoring the <kbd>max_search_results</kbd>
and <kbd>search_allow_no_criteria</kbd> parameters. This has been fixed.</li>
<li><kbd>Product.get</kbd> now also returns the <kbd>flag_types</kbd> field
containing all the relevant data for attachment and [% terms.bug %] flag types.</li>
<li><kbd>Product.get</kbd> now throws an error if neither <kbd>ids</kbd> nor
<kbd>names</kbd> is passed to the method.</li>
<li>When requesting data for your own account using <kbd>User.get</kbd>,
this method now returns two additional fields: <kbd>saved_searches</kbd>
and <kbd>saved_reports</kbd> containing all your saved searches and
graphical and tabular reports.</li>
<li><kbd>User.get</kbd> now also returns the <kbd>groups</kbd> field
containing the list of groups the user belongs to. The list is filtered
based on your privileges.</li>
</ul>
<h2 id="v44_issues">Outstanding Issues</h2>
<ul>
<li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=89822">
[%- terms.Bug %] 89822</a>: When changing multiple [% terms.bugs %] at

</ul>
<h2 id="v44_upgrading">Notes On Upgrading From a Previous Version</h2>
<h3>IMPORTANT: Apache Configuration Change</h3>
<p>
For improved security, [% terms.Bugzilla %] now prevents directory browsing
by default. In order to do that, the root <kbd>bugzilla/.htaccess</kbd> file
now contains the <kbd>Options -Indexes</kbd> directive. By default, this
directive is not allowed in <kbd>.htaccess</kbd> and so you must configure
Apache to allow it. To do that, add <kbd>Options</kbd> to the
<kbd>AllowOverride</kbd> directive in <kbd>httpd.conf</kbd>. This means you
should now have something like this:
<p>
<kbd>AllowOverride Limit FileInfo Indexes Options</kbd>
</p>
Check the
<a href="http://www.bugzilla.org/docs/4.4/en/html/configuration.html#http-apache">documentation</a>
for more information about how to configure Apache.
</p>
<h2 id="v44_code_changes">Code Changes Which May Affect Customizations and Extensions</h2>
<ul>
<li>The <em>usebugaliases</em> parameter has been removed. Aliases are now
always available.</li>
<li>There is a new code hook <kbd>admin_editusers_action</kbd> to alter the
way <kbd>editusers.cgi</kbd> works.</li>
<li>There is a new code hook <kbd>buglist_column_joins</kbd> to alter the way
tables and columns are joined in queries. In combination with the
<kbd>buglist_columns</kbd> hook, this permits to customize the list of
columns to display in buglists.</li>
<li>There is a new code hook <kbd>bug_start_of_update</kbd> which is called
after <kbd>object_end_of_update</kbd> but before <kbd>bug_end_of_update</kbd>
for a better control on how to update [% terms.bugs %].</li>
<li>There is a new code hook <kbd>bug_url_sub_classes</kbd> to support
additional URLs in the See Also field.</li>
<li>There is a new code hook <kbd>error_catch</kbd> to catch errors thrown
by [% terms.Bugzilla %] and to take the appropriate actions.</li>
<li>There is a new code hook <kbd>path_info_whitelist</kbd> to whitelist
scripts which should still get the Path-Info information from URLs. By
default, Path-Info is now removed before being passed to CGI scripts.</li>
<li>It is now illegal to have a product with no components and no versions.
Trying to delete the last component or version of a product is now
rejected.</li>
<li>Trying to set the component, target milestone or version of [% terms.abug %]
to a disabled value is no longer accepted. The change will be rejected.</li>
<li>The comment box now checks the returned value of check_can_change_field()
to determine if it should be displayed or not. This means its visibility
can now be controlled by the <kbd>bug_check_can_change_field</kbd> hook.</li>
<li>Flags now checks the returned value of check_can_change_field() to
determine if they should appear as editable or not. This means their
visibility can now be controlled by the <kbd>bug_check_can_change_field</kbd>
hook.</li>
<li>Quips can no longer exceed 512 characters. Existing quips longer than
that are automatically truncated when upgrading.</li>
<li>The static <kbd>bugzilla.dtd</kbd> file has been replaced by a dynamic
one to take custom fields into account. The old
<em><urlbase>/bugzilla.dtd</em> URL is now
<em><urlbase>/page.cgi?id=bugzilla.dtd</em>.</li>
<li>There is a new extension located at <kbd>extensions/MoreBugUrl/</kbd>
which permits to add new classes of URLs in the See Also field. It uses
the <kbd>bug_url_sub_classes</kbd> hook mentioned above.</li>
<li>There is a new <kbd>B[%%]ugzilla->process_cache</kbd> method to store
data which should remain available for the lifetime of the worker process,
on mod_perl. On mod_cgi, it behaves the same way as
<kbd>B[%%]ugzilla->request_cache</kbd>.</li>
<li>In the RDF output of <kbd>config.cgi</kbd>, URIs used to identify
versions and target milestones have been changed to be unique across
products.</li>
<li>The RDF output of <kbd>config.cgi</kbd> now also returns data about
classifications.</li>
<li>It is now legal to call <kbd>B[%%]ugzilla::Version->check({ id => $id })</kbd>
and <kbd>B[%%]ugzilla::Milestone->check({ id => $id })</kbd> to validate
and get an object using its ID.</li>
<li>Rows in the <kbd>dependencies</kbd>, <kbd>flaginclusions</kbd> and
<kbd>flagexclusions</kbd> DB tables are now enforced to be unique.</li>
<li>The <kbd>b[%%]ugs_activity</kbd> and <kbd>profiles_activity</kbd> DB
tables now have an auto-incremented primary key named <kbd>id</kbd>.</li>
<li>A custom <kbd>B[%%]ugzilla.pm</kbd> module has been added into
<kbd>contrib/</kbd> to help packagers to package B[%%]ugzilla in their
Linux distros.</li>

<h2 id="v42_introduction">Introduction</h2>
<p>Welcome to [% terms.Bugzilla %] 4.2! It has been almost a year since we
released [% terms.Bugzilla %] 4.0 on February 2011, and this new major
release comes with several new features and improvements. This release
contains major improvements to search, support for SQLite, improved
WebServices, and lots of other enhancements.</p>

<h3>4.2.3</h3>
<p>This release fixes two security issues. See the
<a href="http://www.bugzilla.org/security/3.6.10/">Security Advisory</a>
for details.</p>
<p>In addition, the following important fixes/changes have been made in this
release:</p>
<ul>
<li>Attaching a file to [% terms.abug %] was broken due to a change in
Perl 5.16.

(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=772953">[% terms.Bug %] 772953</a>)</li>
<li>An admin could unintentionally break the display of buglists if a custom
field description contains a < or > character, because these characters
were not filtered.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=785917">[% terms.Bug %] 785917</a>)</li>
<li>Adding or removing a DB column in Oracle didn't handle SERIAL columns
correctly.

</ul>
<h3>4.2.2</h3>
<p>This release fixes two security issues. See the
<a href="http://www.bugzilla.org/security/3.6.9/">Security Advisory</a>
for details.</p>
<p>In addition, the following important fixes/changes have been made in this
release:</p>
<ul>
<li>A regression introduced in [% terms.Bugzilla %] 4.0 caused some login
names to be ignored when entered in the CC list of [% terms.bugs %].
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=756314">[% terms.Bug %] 756314</a>)</li>
<li>Some queries could trigger an invalid SQL query if strings entered by
the user contained leading or trailing whitespaces.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=760075">[% terms.Bug %] 760075</a>)</li>
<li>The auto-completion form for keywords no longer automatically selects

<li>Keywords are now correctly escaped in the auto-completion form to prevent
any XSS abuse.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=754561">[% terms.Bug %] 754561</a>)</li>
<li>A regression introduced in [% terms.Bugzilla %] 4.0rc2 when fixing
CVE-2011-0046 caused the "Un-forget the search" link to not work correctly
anymore when restoring a deleted saved search, because this link was
lacking a valid token.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=768870">[% terms.Bug %] 768870</a>)</li>
<li>Two minor CSRF vulnerabilities have been fixed which could let an attacker

(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=754672">[% terms.Bugs %] 754672</a>
and <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=754673">754673</a>)</li>
</ul>
<h3>4.2.1</h3>
<p>This release fixes one security issue. See the
<a href="http://www.bugzilla.org/security/3.6.8/">Security Advisory</a>
for details.</p>
<p>In addition, the following important fixes/changes have been made in this
release:</p>
<ul>
<li>Due to a regression introduced when fixing CVE-2012-0453, if an XML-RPC
client sets the charset as part of its Content-Type header, we were
incorrectly rejecting the request. The header is now correctly parsed.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=731219">[% terms.Bug %] 731219</a>)</li>
<li>Email notifications about status changes in blockers were incorrectly
formatted. Several pieces of text were missing in the emails.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=731586">[% terms.Bug %] 731586</a>)</li>
<li>Many [% terms.bugs %] related to the searching system have been fixed.
(<a href="https://bugzilla.mozilla.org/buglist.cgi?bug_id=58179,715270,730984,731163,737436">
[% terms.Bugs %] 58179, 715270, 730984, 731163 and 737436</a>)</li>
<li>When using the QuickSearch box, complex queries are now parsed correctly.
It also behaves correctly with non-ASCII characters (such as é, ä, ü, etc.).
(<a href="https://bugzilla.mozilla.org/buglist.cgi?bug_id=554819,663377,730207">
[% terms.Bugs %] 554819, 663377 and 730207</a>)</li>
<li>The 'take' link besides the assignee field now works correctly when
the <kbd>usemenuforusers</kbd> parameter is turned on.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=734997">[% terms.Bug %] 734997</a>)</li>
<li>URLs in the 'Total' row at the bottom of tabular reports were broken
when JavaScript was enabled and a user field was used for the vertical
axis.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=731323">[% terms.Bug %] 731323</a>)</li>
<li>Some performance problems have been fixed for installations with many
products, components or versions.
(<a href="https://bugzilla.mozilla.org/buglist.cgi?bug_id=695514,731055">
[% terms.Bugs %] 695514 and 731055</a>)</li>
<li>A new hook named <kbd>buglist_column_joins</kbd> has been added to let
extensions alter the <kbd>Bugzilla::Search::COLUMN_JOINS</kbd> hash.
Now more fields can be displayed as columns in buglists, in combination
with the already existing <kbd>buglist_columns</kbd> hook.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=743991">[% terms.Bug %] 743991</a>)</li>
<li>A new hook named <kbd>admin_editusers_action</kbd> has been added to let
extensions alter the behavior of <kbd>editusers.cgi</kbd>. This lets you add
new features to this script very easily.

</ul>
<h3 id="v42_feat_sqlite">Experimental SQLite Support</h3>
<p>SQLite is now supported by [% terms.Bugzilla %] and becomes the 4th supported
database besides MySQL, PostgreSQL and Oracle. SQLite support must be considered
as experimental, at least till the next major release.</p>
<p>Note that use of SQLite is only recommended for small installations. Larger
installations should use MySQL, PostgreSQL, or Oracle.</p>
<h3 id="v42_feat_attach">Creating an Attachment by Pasting Text Into a Text Field</h3>
<p>You can now create a new attachment simply by pasting some text into a text
field, in addition to the normal upload process for attachments.</p>
<h3 id="v42_feat_email">HTML [% terms.Bug %]mail</h3>
<p>By default, [% terms.bug %]mails (email notifications about changes to
[%+ terms.bugs %]) are now sent in an HTML format that is more readable than
the old text format. Those who prefer the old text format can still choose it
in their Preferences, however.</p>
<h3 id="v42_feat_search">Improved Searching System</h3>
<p>The Custom Search section in the Advanced Search page has been redesigned
to work in a more sensible way. Complex queries are easier to build and have
more sensible results, as they are built using a more intuitive logic.
Some very complicated queries are still impossible to generate, though.
Things should improve in future releases.</p>
<h3 id="v42_feat_product">Disabling Old Components, Versions and Milestones</h3>
<p>Older components, versions and milestones can now be disabled. [% terms.Bugs %]
already using them are not affected, but these values will no longer be
available for new [% terms.bugs %].</p>
<h3 id="v42_feat_custom">Displaying a Custom Field Value Based on Multiple Values
of Another Field</h3>
<p>A custom field can now be displayed based on multiple values of another field.
(For example, one custom field could now appear in multiple products.)
Previously, you could only display a custom field based on a single value of
another field.</p>
<h3 id="v42_feat_audit">Auditing of All Changes Within [% terms.Bugzilla %]</h3>
<p>Most changes made through the admin interface are now logged to the database,
in the <kbd>audit_log</kbd> table. There is no UI to access this table yet,
but developers are free to create their own tools to track changes made into
their installation. This is only a first step, and improvements are expected
in future releases.</p>
<h3 id="v42_feat_wai">Accessibility Improvements</h3>
<p>A project has started thanks to Francisco Donalisio from IBM to make
[%+ terms.Bugzilla %] compliant with the W3C Web Accessibility Initiative
standards. A lot more work still needs to be done, but we expect a much
better compatibility for the next major release.</p>
<h3 id="v42_feat_other">Other Enhancements and Changes</h3>
<h4>Enhancements for Users</h4>
<ul>
<li><strong>[% terms.Bugs %]:</strong> Users without editbugs privileges can
no longer remove other users from the CC list of [% terms.bugs %].</li>
<li><strong>[% terms.Bugs %]:</strong> Local [% terms.bug %] IDs are now valid
in the See Also field. Adding such an ID will also add a reciprocal link in
the other [% terms.bug %].</li>
<li><strong>[% terms.Bugs %]:</strong> After editing [% terms.abug %] or an
attachment, the URL is automatically changed to <kbd>show_bug.cgi</kbd>
instead of <kbd>post_bug.cgi</kbd>, <kbd>process_bug.cgi</kbd> or
<kbd>attachment.cgi</kbd> so that reloading the page (for instance when
restarting the web browser) displays the right page. This feature is supported
by Firefox, Chrome and Safari, but not by Internet Explorer 9.</li>
<li><strong>[% terms.Bugs %]:</strong> Inactive accounts are no longer
displayed in user fields when user-autocompletion is enabled.</li>
<li><strong>[% terms.Bugs %]:</strong> User-autocompletion is now much faster
on installations with many user accounts.</li>
<li><strong>[% terms.Bugs %]:</strong> The See Also field now accepts URLs
pointing to MantisBT, Trac, JIRA and the sourceforge.net b[%%]ug trackers.</li>
<li><strong>[% terms.Bugs %]:</strong> Displaying [% terms.abug %] with many
dependencies is now much faster.</li>
<li><strong>Attachments:</strong> The encoding of text files can be automatically
detected when uploading them as attachments.</li>
<li><strong>Attachments:</strong> Clickjacking could possibly occur in an attachment
Details page if a user attached a specially formatted HTML file. To fix this
potential problem, the Details page always displays the HTML source instead and
users can see rendered page by clicking on View.</li>
<li><strong>Flags:</strong> Changing the requestee of a flag no longer changes
the requester.</li>
<li><strong>Reports:</strong> If JavaScript is enabled in your web browser,
tabular reports are now sortable based on any displayed column.</li>
<li><strong>Dependency graphs:</strong> The <em>Show every [% terms.bug %] in
the system with dependencies</em> option has been removed.</li>
<li><strong>Searches:</strong> The columns displayed by default in
[%+ terms.bug %]lists have changed. These columns are now displayed by default
unless otherwise specified:<br>
<kbd>product | component | assignee | [% terms.bug %] status | resolution |
[%+ terms.bug %] summary | last change date</kbd><br>
This means that the priority, severity and operating system columns are no
longer displayed by default.</li>
<li><strong>Searches:</strong> [% terms.Bug %]lists will now only display the
first 500 [% terms.bugs %] by default. It is still possible to display the
whole list, though.</li>
<li><strong>Searches:</strong> When using relative dates and times, <kbd>-1w</kbd>
is now a synonym for <kbd>-7d</kbd> and means exactly 7 days. Previously,
<kbd>-1w</kbd> meant the beginning of the week, which was confusing some users.
The same confusion existed for <kbd>-1d</kbd> which was different from
<kbd>-24h</kbd>, and for <kbd>-1m</kbd> which was different from <kbd>-30d</kbd>.
Now if you really want the beginning of the day, week or month, you must use
<kbd>-1ds</kbd>, <kbd>-1ws</kbd>, and <kbd>-1ms</kbd> respectively, where
"s" means "start of". This change will affect existing saved searches using
relative dates.</li>
<li><strong>Searches:</strong> A new <em>Include fulltext when performing quick
searches</em> user preference has been added which permits users to include
or exclude comments when using quicksearches.</li>
<li><strong>Searches:</strong> It is now possible to query for [% terms.bugs %]
based on personal tags in the Custom Search section in the Advanced Search
page.</li>
<li><strong>Email notifications: </strong> The date and time of comments are no
longer displayed in the comment header in [% terms.bug%]mails. This information
is already available in the email header itself.</li>
</ul>
<h4>Enhancements for Administrators and Developers</h4>
<ul>
<li><strong>Installation:</strong> <kbd>checksetup.pl</kbd> is now much quieter
when creating a new database.</li>
<li><strong>Security:</strong> [% terms.Bugzilla %] 4.0 is using
<kbd>Math::Random::Secure</kbd> to generate cryptographically secure
pseudorandom numbers, but it appeared that installing this Perl module from
CPAN caused a lot of trouble for some people due to its numerous dependencies.
So the RNG code has been rewritten to only depend on <kbd>Math::Random::ISAAC</kbd>,
which was already in use in previous versions of [% terms.Bugzilla %].</li>
<li><strong>Security:</strong> <kbd>X-Frame-Options = SAMEORIGIN</kbd> is now
passed to all page headers (except when viewing attachments, as they can be
on a different host) to protect users from framing and subsequent possible
clickjacking problems.</li>
<li><strong>Configuration:</strong> A new parameter <em>password_complexity</em>
has been added (default: no_constraints) which allows admins to force users
to use passwords with a higher complexity, such as a combination of uppercase
and lowercase letters, numbers and special characters, or a subset of them.</li>
<li><strong>Configuration:</strong> A new parameter <em>search_allow_no_criteria</em>
has been added (default: on) which allows admins to forbid queries with no
criteria. This is particularly useful for large installations with several
tens of thousands [% terms.bugs %] where returning all [% terms.bugs %]
doesn't make sense and would have a performance impact on the database.</li>
<li><strong>Configuration:</strong> A new parameter <em>default_search_limit</em>
has been added (default: 500) which limits the number of [% terms.bugs %]
displayed by default in a [% terms.bug%]list. The user can ask to see a larger
list, though.</li>
<li><strong>Configuration:</strong> A new parameter <em>max_search_results</em>
has been added (default: 10000) which limits the number of [% terms.bugs %]
a user can request at once in a [% terms.bug%]list. This is a hard limit and
a user cannot bypass this value.</li>
<li><strong>Configuration:</strong> A new parameter <em>ajax_user_autocompletion</em>
has been added (default: on) to allow administrators to disable auto-completion
when typing characters in user fields. This parameter should only be disabled
if your installation is unable to support the load generated by this feature.</li>
<li><strong>Configuration:</strong> The <em>config_modify_panels</em> hook now
lets you add additional parameters to existing parameters panels.</li>
<li><strong>Flags:</strong> Users with local editcomponents privileges can now
edit flag types for products they can administer.</li>
<li><strong>Quips:</strong> A new system group <em>bz_quip_moderators</em> has
been created to moderate quips. Till now, you had to be in the <em>admin</em>
group to do that.</li>
<li><kbd>importxml.pl</kbd> now inserts each comment separately into the imported
[%+ terms.bug %] instead of concatenating them all into a single comment.</li>
<li><kbd>email_in.pl</kbd> now ignores auto-submitted incoming emails (for
instance, all these "out of office" emails).</li>
<li>New code hooks: email_in_before_parse, email_in_after_parse,
install_filesystem, install_update_db_fielddefs, job_map, object_end_of_create,
quicksearch_map, user_preferences.</li>
</ul>
<h4>WebService Changes</h4>
<ul>
<li>Two new methods have been added: <kbd>Product.create</kbd> and
<kbd>Group.create</kbd>.</li>
<li><kbd>B[%%]ug.update</kbd> no longer throws an error when passing an empty
string to <kbd>see_also</kbd>. It now simply ignores this empty value.</li>
<li><kbd>Product.get</kbd> now also returns data about the classification it
belongs to as well as its components, milestones and versions. It also
returns the <kbd>default_milestone</kbd> and <kbd>has_unconfirmed</kbd>
attributes.</li>
<li>In <kbd>B[%%]ug.fields</kbd>, the <kbd>sortkey</kbd> attribute used in
<kbd>values</kbd> has been renamed to <kbd>sort_key</kbd>.</li>
<li>In <kbd>B[%%]ug.attachments</kbd> and <kbd>B[%%]ug.add_attachment</kbd>,
the <kbd>is_url</kbd> attribute no longer exists.</li>
</ul>
<h2 id="v42_issues">Outstanding Issues</h2>
<ul>
<li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=89822">

</ul>
<h2 id="v42_code_changes">Code Changes Which May Affect Customizations and Extensions</h2>
<ul>
<li>The <kbd>email/newchangedmail.txt.tmpl</kbd> template is now fully templatized,
meaning that the diff table displaying changes in [% terms.bug %] fields is
now generated in the template itself. This means [% terms.bug %]mails are now
fully localizable.</li>
<li>The bugmail_recipients hook has been modified to pass <kbd>diffs</kbd> with
changes made to the [% terms.bug %] as well as <kbd>users</kbd> including
recipients of the email notification.</li>
<li>YUI has been upgraded to 2.9.0.</li>
<li>Due to the major code refactor of <kbd>B[%%]ugzilla/Search.pm</kbd>, any
customization made against this file will probably need to be rewritten.</li>
<li>The [% terms.Bugzilla %]-specific <kbd>url_quote</kbd> filter used in templates
has been removed and replaced by the <kbd>uri</kbd> filter from Template::Toolkit
as they are now similar.</li>
<li><kbd>long_list.cgi</kbd>, <kbd>showattachment.cgi</kbd> and <kbd>xml.cgi</kbd>
have been removed from the codebase. As <a href="#v40_code_changes">announced</a>
in the release notes of [% terms.Bugzilla %] 4.0, these scripts were deprecated
since [% terms.Bugzilla %] 2.19.</li>
<li><kbd>sidebar.cgi</kbd> has been removed, because Gecko-based browsers no
longer support remote XUL, and its popularity is very low.</li>
<li><kbd>contrib/yp_nomail.sh</kbd> has been removed. This script is no longer
useful since [% terms.Bugzilla %] 3.0.</li>
<li><kbd>contrib/bugzilla_ldapsync.rb</kbd> has been removed. This script didn't
work for a long time.</li>

</ul>
<h2 id="v40_introduction">Introduction</h2>
<p>This is [% terms.Bugzilla %] 4.0! Since 3.6 (our previous major
release) we've come a long way, and we've come even further compared to
3.0 in 2007! Since [% terms.Bugzilla %] 3.0, almost every major user
interface in [% terms.Bugzilla %] has been redesigned, the WebServices have
evolved enormously, there's a great new Extensions system, and there
are hundreds of other new features. With the major redesigns that come
particularly in this release compared to 3.6, we felt that it was time to
call this release 4.0.</p>
<p>It's not just major WebService and UI enhancements that are new in
[%+ terms.Bugzilla %] 4.0—there are many other exciting new features,
including automatic duplicate detection, enhanced custom field
functionality, autocomplete for users, search improvements, and much
more. Overall, 4.0 is far and away the best version of [% terms.Bugzilla %]
we've ever released.</p>
<p>If you're upgrading, make sure to read <a href="#v40_upgrading">Notes
On Upgrading From a Previous Version</a>. If you are upgrading from a release
before 3.6, make sure to read the release notes for all the
<a href="#v40_previous">previous versions</a> in between your version
and this one, <strong>particularly the Upgrading section of each
version's release notes</strong>.</p>
<p>We would like to thank
<a href="http://www.itasoftware.com/">ITA Software</a>,
the <a href="http://www.ibm.com/linux/ltc/">IBM Linux Technology Center</a>,
and <a href="http://www.redhat.com/">Red Hat</a> for funding the development
of certain features and improvements in this release of
[%+ terms.Bugzilla %].</p>
<h2 id="v40_point">Updates in this 4.0.x Release</h2>
<h3>4.0.2</h3>
<p>This release fixes several security issues. See the
<a href="http://www.bugzilla.org/security/3.4.11/">Security Advisory</a>
for details.</p>
<p>In addition, the following important fixes/changes have been made in this
release:</p>
<ul>
<li>The <kbd>B[% %]ug.create</kbd> WebService method now throws an error if you
pass a group name which doesn't exist. In [% terms.Bugzilla %] 4.0 and 4.0.1,
this group name was silently ignored, leaving your [% terms.bug %] unsecure
if no other group applied.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=653341">[% terms.Bug %] 653341</a>)</li>
<li>Moving several [% terms.bugs %] at once into another product displayed the
same confirmation page again and again, and changes were never committed
(regressed in 4.0).
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=663208">[% terms.Bug %] 663208</a>)</li>
<li>Marking [% terms.abug %] as a duplicate now works in Internet Explorer 9.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=656769">[% terms.Bug %] 656769</a>)</li>
<li><kbd>importxml.pl</kbd> no longer crashes when importing keywords (regressed
in 4.0).
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=657707">[% terms.Bug %] 657707</a>)</li>
<li>Data entered while reporting a new [% terms.bug %] could be lost if you had
to click the "Back" button of your web browser.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=652427">[% terms.Bug %] 652427</a>)</li>
<li>WebServices methods will return undefined [% terms.bug %] fields as undefined
instead of as an empty string. This change is consistent with how
[%+ terms.Bugzilla %] 4.2 behaves.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=657561">[% terms.Bug %] 657561</a>)</li>
<li>The XML-RPC interface now works with SOAP::Lite 0.711 and 0.712 under mod_perl.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=600810">[% terms.Bug %] 600810</a>)</li>
<li>LWP 6.00 and newer require Perl 5.8.8 and above. When installing this module
using <kbd>install-module.pl</kbd> on a Perl installation older than 5.8.8,
LWP 5.837 will be installed instead.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=655912">[% terms.Bug %] 655912</a>)</li>
<li>Viewing [% terms.abug %] report should be significantly faster when your
installation has many custom fields.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=634812">[% terms.Bug %] 634812</a>)</li>
</ul>
<h3>4.0.1</h3>
<ul>
<li>During installation, the CPAN module Math::Random::Secure would
sometimes fail to install properly and give an error about
<kbd>Math::Random::Secure::irand</kbd>. Now, when using
<kbd>install-module.pl</kbd> to install Math::Random::Secure, this
will no longer happen. If you are currently experiencing this b[% %]ug
and it prevented you from installing 4.0, remove Math::Random::Secure
from your <kbd>lib/</kbd> directory, like:
<p><kbd>rm -rf lib/Math/Random/Secure*</kbd></p>
<p>(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=646578">[% terms.Bug %] 646578</a>)</p></li>
<li>The "Remember values as bookmarkable template" button on the
[%+ terms.bug %] entry page will now work even when some required fields
are empty.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=640719">[% terms.Bug %] 640719</a>)</li>
<li>Email notifications about dependencies and flags had the wrong
timestamp.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=643910">[% terms.Bug %] 643910</a>
and (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=652165">[% terms.Bug %] 652165</a>)</li>
<li>You can now select "UTC" as a valid timezone in General Preferences.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=646209">[% terms.Bug %] 646209</a>)</li>
<li>Automatic duplicate detection now works on PostgreSQL (although
it is not as high-quality as on other DB platforms).
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=634144">[% terms.Bug %] 634144</a>)</li>
<li>Autcomplete for users now works even if you are using the
"emailsuffix" option.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=641519">[% terms.Bug %] 641519</a>)</li>
<li>Javascript errors during series creation in New Charts have been
fixed.
(<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=644285">[% terms.Bug %] 644285</a>)</li>
<li>The "Show Votes" page now works, for installations using the Voting
extension.

<h3 id="v40_req_apache">Optional Apache Modules</h3>
<p>If you are using Apache as your webserver, [% terms.Bugzilla %] can
now take advantage of some Apache features if you have the below Apache
modules installed and enabled. Currently,
<a href="#v40_feat_js_css_update">certain [% terms.Bugzilla %] features</a>
are enabled only if you have all of the following modules installed

<li>mod_headers</li>
<li>mod_expires</li>

</ul>
<h3 id="v40_feat_dup">Automatic Duplicate Detection When Filing
[%+ terms.Bugs %]</h3>
<p>When filing [% terms.abug %], as soon as you start typing in the summary
field, [% terms.Bugzilla %] will suggest possible duplicates of the
[%+ terms.bug %] you are filing.</p>
<p>In order for this feature to work, all pre-requisites for JSON-RPC
support must be installed on your [% terms.Bugzilla %]. It will be
much faster on installations that run under mod_perl than it will
be on other installations.</p>
<h3 id="v40_feat_search_ui">New Advanced Search UI</h3>
<p>Thanks to the UI work of <a href="http://guy-pyrzak.blogspot.com/">Guy
Pyrzak</a>, the Advanced Search UI has been completely redesigned.
It is now much simpler, and far more approachable for new users, while
still retaining all of the features that power users are used to.</p>
<h3 id="v40_feat_attach_ui">New Attachment Details UI</h3>
<p>The UI used for editing attachment details has been completely
redesigned, allowing for a normally-size comment box to be used
when commenting on attachments, and allowing nearly the entire screen
width to be used when doing code reviews or editing an attachment as
a comment.</p>
<p>Thanks to <a href="http://guy-pyrzak.blogspot.com/">Guy Pyrzak</a> for
his excellent work on this UI redesign.</p>
<h3 id="v40_feat_autocomplete">Autocomplete for Users and Keywords</h3>
<p>Once you type at least three characters in any field that can contain a user
(including the [% field_descs.cc FILTER html %],
[%+ field_descs.qa_contact FILTER html %], or
[%+ field_descs.assigned_to FILTER html %] fields), a list will appear
containing all of the users whose real names or usernames match what you are
typing. Your [% terms.Bugzilla %] must have all of the optional Perl
modules required for JSON-RPC support installed, though, in order for
this feature to work. Also, this feature will be <strong>much</strong>
faster on installations that run under mod_perl than it will be on
other installations.</p>
<p>There is also a similar autocomplete for the Keywords field. The
Keywords autocomplete does not require JSON-RPC.</p>
<h3 id="v40_feat_ui">General Usability Improvements</h3>
<p>In addition to the enhancements listed above, there have been
<strong>many</strong> improvements made across the [% terms.Bugzilla %]
user interface. For a list of specific enhancements that were significant,
see the <a href="#v40_feat_other">Other Enhancements and Changes</a>
section.</p>
<h3 id="v40_feat_workflow">New Default Status Workflow</h3>
<p>For new installations of [% terms.Bugzilla %], the default set of
statuses will now be:</p>
<ul>
<li>UNCONFIRMED</li>
<li>CONFIRMED</li>
<li>IN_PROGRESS</li>
<li>RESOLVED</li>
<li>VERIFIED</li>
</ul>
<p>And the UNCONFIRMED status will be enabled by default in all products.</p>
<p>On upgrade, existing installations will not be affected--you will retain
your existing status workflow. However, we strongly recommend that you
update your existing workflow to the new one, using a special tool
we've included, <kbd>contrib/convert-workflow.pl</kbd>, which you
can run after you use <kbd>checksetup.pl</kbd> to upgrade. The
<kbd>whineatnews.pl</kbd> and <kbd>bugzilla-submit</kbd> scripts
will probably not work properly if you continue to use the old workflow
(though most other parts of [% terms.Bugzilla %] will still function
normally).</p>
<p>For more information about the workflow and our rationale for changing
it, see the
<a href="http://bugzillaupdate.wordpress.com/2010/07/06/bugzilla-4-0-has-a-new-default-status-workflow/">blog
post about it</a> and the

where the change was made</a>.</p>
<h3 id="v40_feat_lists">"Last Search" Now Remembers Multiple Searches</h3>
<p>At the top of every [% terms.bug %] in [% terms.Bugzilla %], there are
links that look like: "First", "Last", "Prev", "Next", and
"Show last search results". In earlier versions of [% terms.Bugzilla %],
if you did two separate searches in separate windows, these links would
only work for the <em>last</em> search you did. Now, [% terms.Bugzilla %]
will "remember" which search result you came from and give you the right
"last search results" or "next [% terms.bug %]" from <em>that</em> list,
instead of always using your most recent search.</p>
<p>There are still some situations where [% terms.Bugzilla %] will have to
"guess" which search you are trying to navigate through, but it does its
best to get it right.</p>
<h3 id="v40_feat_jsonp">Cross-Domain WebServices with JSONP</h3>
<p>[% terms.Bugzilla %] now supports making WebService calls from
another domain, inside of a web browser, thanks to support for
<a href="http://bob.pythonmac.org/archives/2005/12/05/remote-json-jsonp/">JSONP</a>.
This will allow for web "mash-ups" to use [% terms.Bugzilla %] data.
When using JSONP, you may only call functions that <em>get</em> data,
you may not call functions that <em>change</em> data.</p>
<p>For more details, see the
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Server/JSONRPC.html#JSONP">JSONP
section</a> of the JSON-RPC WebService documentation.</p>
<h3 id="v40_feat_ws">Major WebService Enhancements</h3>
<p>The WebService has been expanded considerably. The WebService should now be
able to do everything with [% terms.bugs %] that you can do via the
web interface, including updating [% terms.bugs %], adding attachments,
and getting attachment data. For specifics, see the
<a href="#v40_feat_ws_changes">WebService Changes</a> section of these
release notes.</p>
<h3 id="v40_feat_mandatory">Mandatory Custom Fields</h3>
<p>You can now specify that certain custom fields are "mandatory",
meaning that they must have a value when [% terms.abug %] is filed,
and they can never be empty after that.</p>
<h3 id="v40_feat_vot_ext">Voting Is Now An Extension</h3>
<p>All of the code for voting in [% terms.Bugzilla %] has been moved
into an extension, called "Voting", in the <kbd>extensions/Voting/</kbd>
directory. To enable it, you must remove the <kbd>disabled</kbd> file
from that directory, and run <kbd>checksetup.pl</kbd>.</p>
<p>In a future version of [% terms.Bugzilla %], the Voting extension will
be moved outside of the [% terms.Bugzilla %] core code, so we are looking
for somebody who has an interest in the Voting system and would like to
maintain it as a separate extension. There are many enhancement requests
that have been made against the Voting system, and the best way for those
to get addressed is for somebody to step up and offer to maintain the
system outside of [% terms.Bugzilla %]'s core code.</p>
<h3 id="v40_feat_js_css_update">Users Get New CSS and Javascript
Automatically</h3>
<p>In past versions of [% terms.Bugzilla %], if you changed
[%+ terms.Bugzilla %]'s CSS or Javascript files, then every user of
[%+ terms.Bugzilla %] would have to clear their cache in order to get
the updated files. Now, if you are using Apache as your webserver and
you have the <a href="#v40_req_apache">optional Apache modules</a>
installed and enabled, users will automatically get every new version of
[%+ terms.Bugzilla %]'s Javascript and CSS without having to clear
their caches.</p>
<p>This feature also gives a slight performance speedup to
[%+ terms.Bugzilla %] in some cases, and so we recommend that all
administrators install and enable the optional Apache modules if possible.</p>
<h3 id="v40_feat_hooks">Many New Hooks</h3>
<p>Many new code hooks have been added for use by Extensions,
in [% terms.Bugzilla %] 4.0. Now Extensions can access and modify
nearly every part of [% terms.Bugzilla %].</p>
<h3 id="v40_feat_apache_config">New Apache Configuration</h3>
<p>If you run [% terms.Bugzilla %] under Apache (as most people do),
you most likely require a <strong>new Apache configuration</strong>
for this version of [% terms.Bugzilla %]. See the
<a href="#v40_upgrading">Notes On Upgrading From a Previous Version</a>
section for details.</p>
<h3 id="v40_feat_other">Other Enhancements and Changes</h3>
<h4>Enhancements for Users</h4>
<ul>
<li>Now, everywhere in [% terms.Bugzilla %] where you can enter a date,
there is a Calendar widget where you can select the date on a
calendar.</li>
<li>The big icons on the front page have been replaced with much nicer
icons, thanks to Jon Pink of <a href="http://www.jpink.co.uk/">J. Pink Design</a>!</li>
<li><strong>[% terms.Bugs %]:</strong> When filing [% terms.bugs %],
you will now be warned if you forgot to fill in any mandatory fields,
<em>before</em> the page is submitted.</li>
<li><strong>[% terms.Bugs %]:</strong> When filing [% terms.abug %],
you can hover your mouse over any of the field labels on the page
to get a brief description of what that field is and what its purpose
is.</li>
<li><strong>[% terms.Bugs %]:</strong> When adding Hours Worked to [% terms.abug %],
you are no longer required to comment.</li>
<li><strong>[% terms.Bugs %]:</strong> There is now a user preference
for whether the comment box appears above or below the existing
comments.</li>
<li><strong>[% terms.Bugs %]:</strong> [% terms.Bugzilla %] will now
send an email for every comment that you mark or un-mark as being
private. (Previous versions of [% terms.Bugzilla %] did not send emails
to users about this change.) The state of comments being made private
is also now stored in [% terms.abug %]'s history.</li>
<li><strong>[% terms.Bugs %]:</strong> The box to "Add [% terms.Bug %] URLs"
in the See Also field is now hidden behind an "(add)" link that you
have to click to see the box.</li>
<li><strong>Searches:</strong> You can now properly search for field values
that have commas in their name, when using the Advanced Search form.</li>
<li><strong>Searches:</strong> The "URL" field can now be shown as a column
in search results.</li>
<li><strong>Searches:</strong> When viewing a search result, you can now
click on the Summary of the [% terms.bug %] in order to go to the
[%+ terms.bug %]-view page, in addition to being able to click on the
[%+ terms.bug %] ID.</li>
<li><strong>Searches:</strong> When doing a search using the "quicksearch"
box in the header or footer, the box will still contain what you searched
for when viewing the search results page.</li>
<li><strong>Searches:</strong> Multi-select custom fields can now be
shown as columns in the search results.</li>
<li><strong>Searches:</strong> When using the Boolean Charts (now called
"Custom Search"), if you specify both a criterion for an attachment
and a criteron for a flag, then only [% terms.bugs %] that have
attachments with that flag will be found.</li>
<li><strong>Searches:</strong> If you hover your mouse over the field labels
on the Advanced Search page, you will get a description of what that
field is.</li>
<li><strong>Searches:</strong> When searching via a saved search, if you
accidentally click on "Forget Search", there is a link to undo it.</li>
<li><strong>Searches:</strong> When using the Boolean Charts (now called
"Custom Search"), you can search for values "greater than or equal to"
or "less than or equal to" some value.</li>
<li><strong>Flags:</strong> If you hover your mouse over the name of
a flag setter when viewing [% terms.abug %], you can see that
flag setter's full name and complete username.</li>
<li><strong>Flags:</strong> When setting a flag on [% terms.abug %],
the box for entering a requestee does not appear until you set the flag
to "?", now.</li>
<li><strong>Flags:</strong> On the "My Requests" page, [% terms.bugs %]
that are restricted to certain groups now properly have the "padlock"
icon shown next to them to indicate that they may contain confidential
information.</li>
<li>When using the Reports interface, you can now choose many more fields
as the X, Y, or Z axis of a report, including custom fields.</li>
<li>[% terms.Bugzilla %] now prevents
Internet Explorer 8 and later from attempting to render
<kbd>text/plain</kbd> attachments as HTML.</li>
<li>If you receive a Whine mail that is empty, there will now be a brief
message explaining that your search found no results.</li>
<li>The <a href="page.cgi?id=fields.html">Field Help Page</a> now
contains a description of every single field that can be on
[%+ terms.abug %] in [% terms.Bugzilla %].</li>
</ul>
<h4>Enhancements for Administrators and Developers</h4>
<ul>
<li>The system for moving [% terms.bugs %] between installations has been
moved into an extension called <kbd>OldBugMove</kbd>. This system was used
by very few [% terms.Bugzilla %] installations--if you aren't certain
whether or not you are using it, you're not using it. To enable the system,
you have to remove the file <kbd>extensions/OldBugMove/disabled</kbd>
and then run <kbd>checksetup.pl</kbd>. In a future version of [% terms.Bugzilla %],
this extension may be moved outside of the core [% terms.Bugzilla %] code,
so if you are interested in maintaining it, please let us know.</li>
<li><strong>Custom Fields: </strong> "[% terms.Bug %] ID" custom fields can
now represent relationships between [% terms.bugs %], similarly to how the
[%+ field_descs.blocked FILTER html %] and
[%+ field_descs.dependson FILTER html %] fields work now.</li>
<li><strong>Custom Fields:</strong> You can now restrict the visibility
of custom fields and their values to a specific Component or
Classification.</li>
<li>The "keyword cache" has been removed. When you edit keywords, you no
longer will have to "rebuild the keyword cache" after you are done.</li>
<li>Running <kbd>./collectstats.pl --regenerate</kbd> will now take
minutes or hours, instead of days.</li>
<li>When using <kbd>email_in.pl</kbd>, there are two new switches,
<kbd>--default</kbd> and <kbd>--override</kbd>, which allow you to
specify certain default values or override specified values for
<kbd>@field</kbd> values sent in emails. (This also allows you to specify
defaults for everything so that people do not have to specify any field
values when filing [% terms.abug %] via email.)</li>
<li><strong>Installation:</strong> If you are using a localized version of
[%+ terms.Bugzilla %] and your terminal does not understand Unicode,
<kbd>checksetup.pl</kbd> will now attempt to output its messages in your
terminal's character set.</li>
<li><strong>Installation:</strong> [% terms.Bugzilla %] no longer needs empty
"placeholder" CSS in the <kbd>skins/custom</kbd> directory and other
directories. When you update, <kbd>checksetup.pl</kbd> will remove these.
This also significantly reduces the number of HTTP requests required to
load a page for the first time in [% terms.Bugzilla %].</li>
<li><strong>Installation:</strong> For Windows users, [% terms.Bugzilla %]
now supports Strawberry Perl fully.</li>
<li><strong>Installation:</strong> Now, whenever <kbd>checksetup.pl</kbd>
throws an error, it will be printed in the color red, to make it
obvious that something is wrong.</li>
<li><strong>Installation:</strong> Some actions of <kbd>checksetup.pl</kbd> were
silent, in the past. Now, <kbd>checksetup.pl</kbd> will print a message for
almost anything it does.</li>
<li><strong>Installation:</strong> The process of adding foreign keys
to a table is now much faster. This will particularly improve the speed
of upgrading from [% terms.Bugzilla %] 3.4 or earlier.</li>
<li>If you are using <kbd>jobqueue.pl</kbd> and email gets heavily delayed
for some reason, those emails will now have a Date header reflecting the
time they were <em>supposed</em> to be sent, instead of when they actually
<em>were</em> sent.</li>
<li><kbd>./jobqueue.pl install</kbd> now works on SuSE Linux.</li>
<li>[% terms.Bugzilla %] now runs much better in Apache's suexec mode
than it used to. As part of this, <kbd>checksetup.pl</kbd> sets
much stricter permissions on all the files in [% terms.Bugzilla %]
than it used to. In particular, any files that [% terms.Bugzilla %]
does not know about will not be readable by the webserver.</li>
<li>The <kbd>sendmailnow</kbd> parameter has been removed, as it was
not necessary for any modern version of Sendmail or other Mail Transfer
Agent.</li>
<li>When editing a user via the Users administration panel, you can now
see if they are a Default CC on any component.</li>
<li>For new installations of [% terms.Bugzilla %], all users will be
able to see and use the Whining system by default.</li>
<li>When you are using SSL with [% terms.Bugzilla %], you can now
turn on the <kbd>strict_transport_security</kbd> parameter to
send the
<a href="https://developer.mozilla.org/en/Security/HTTP_Strict_Transport_Security">Strict-Transport-Security</a>
header with every HTTPS connection, for additional security.</li>
<li>New code hooks (see their documentation in
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/Hook.html">Bugzilla::Hook</a>):
bug_check_can_change_field, search_operator_field_override,
bugmail_relationships, object_columns, object_update_columns,
and object_validators. The colchange_columns hook has been removed,
as it is no longer necessary (buglist_columns will be used for data
about which columns can be on the [% terms.bug %] list).</li>
<li>When [% terms.Bugzilla %] throws certain types of errors, it will
now include a "traceback" of where exactly the error occurred in the
code, to help administrators and developers debug problems.</li>
<li>There is now a test, <kbd>xt/search.t</kbd>, that assures that all
of the functionality of <kbd>Bugzilla::Search</kbd> is working properly.
If you customize the search functionality of [% terms.Bugzilla %],
you may wish to run this test to assure that your changes are correct.
You can see more information about running this test by doing
<kbd>perldoc xt/search.t</kbd> at the command line.</li>
<li>[% terms.Bugzilla %] now sends the
<a href="https://developer.mozilla.org/en/the_x-frame-options_response_header"><code>X-Frame-Options: SAMEORIGIN</code></a> header
with every page request in order to prevent "clickjacking" attacks. Note
that this prevents other domains from displaying [% terms.Bugzilla %]
in an HTML frame.</li>
</ul>
<h4 id="v40_feat_ws_changes">WebService Changes</h4>
<ul>
<li>You can now call some JSON-RPC methods using HTTP GET, in addition to
using HTTP POST. See the
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Server/JSONRPC.html#Connecting_via_GET">JSON-RPC
documentation</a> for details.</li>
<li>You can now update existing [% terms.bugs %] using the
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Bug.html#update">B[% %]ug.update</a>
function.</li>
<li>You can now add attachments to [% terms.bugs %] using the
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Bug.html#add_attachment">B[% %]ug.add_attachment</a>
function.</li>
<li>The <kbd>B[% %]ug.get</kbd> function now returns all of [% terms.abug %]'s
information other than comments and attachments.</li>
<li><kbd>B[% %]ug.get</kbd> no longer returns the <kbd>internals</kbd> hash.</li>
<li>The <kbd>B[% %]ug.attachments</kbd> function now also returns attachment
data.</li>
<li>The following functions now support the <kbd>include_fields</kbd>
and <kbd>exclude_fields</kbd> arguments: <kbd>B[% %]ug.get</kbd>,
<kbd>B[% %]ug.search</kbd>, and <kbd>B[% %]ug.attachments</kbd>. Also,
server-side performance of the WebService is actually increased when
using these arguments, now, as [% terms.Bugzilla %] will no longer
get data from the database for fields you haven't asked for.</li>
<li>You can now mark the initial description of [% terms.abug %] as
private when filing [% terms.abug %] via the <kbd>B[% %]ug.create</kbd>
function.</li>
<li>You can now specify groups to put [% terms.abug %] in, in the
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Bug.html#create">B[% %]ug.create</a>
function. (This also means that you can specify groups when filing
[%+ terms.abug %] via email_in.pl.)</li>
<li>The <kbd>User.get</kbd> function now accepts <kbd>groups</kbd>
and <kbd>group_ids</kbd> arguments, to limit the returned values to
only users in the specified groups.</li>
<li>There is a new, undocumented B[% %]ug.possible_duplicates
function that helps implement the automatic duplicate detection
system. Because this function is not documented, its API may change
between releases of [% terms.Bugzilla %].</li>
<li>You can no longer search using the <kbd>votes</kbd> argument in
<kbd>B[% %]ug.search</kbd>.</li>
<li><kbd>B[% %]ug.attachments</kbd> now returns the attachment's description
using the name "summary" instead of the name "description", to be
consistent with the fact that [% terms.bug %] summaries are called
"summary". The value is still <em>also</em> returned as "description",
for backwards compatibility, but this backwards compatibility will go
away in [% terms.Bugzilla %] 5.0.</li>
<li>In the return values of various <kbd>B[% %]ug</kbd> functions, the author
of comments, [% terms.bugs %], and attachments is now called "creator",
instead of sometimes being called "reporter", "author", or "attacher".
The old names are retained for backwards-compatibility, and will stay
around until [% terms.Bugzilla %] 5.0.</li>
</ul>
<h2 id="v40_issues">Outstanding Issues</h2>
<ul>
<li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=423439">
[%- terms.Bug %] 423439</a>: Tabs in comments will be converted
to four spaces, due to a b<!-- -->ug in Perl as of Perl 5.8.8.</li>
<li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=89822">
[%- terms.Bug %] 89822</a>: When changing multiple [% terms.bugs %] at
the same time, there is no "mid-air collision" protection.</li>
<li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=276230">
[%- terms.Bug %] 276230</a>: The support for restricting access to
particular Categories of New Charts is not complete. You should treat
the 'chartgroup' Param as the only access mechanism available.<br>
However, charts migrated from Old Charts will be restricted to
the groups that are marked MANDATORY for the corresponding Product.
There is currently no way to change this restriction, and the
groupings will not be updated if the group configuration
for the Product changes.</li>
</ul>
<h2 id="v40_upgrading">Notes On Upgrading From a Previous Version</h2>
<h3>IMPORTANT: Apache Configuration Change</h3>
<h4>mod_cgi</h4>
<p>If you run [% terms.Bugzilla %] under mod_cgi (this is the most common
configuration, involving a <Directory> block in your Apache config
file), you will need to update the configuration of Apache for
[%+ terms.Bugzilla %]. In particular, this line in the [% terms.Bugzilla %]
<kbd><Directory></kbd> block:</p>
<blockquote><code>AllowOverride Limit</code></blockquote>
<p>needs to become:</p>
<blockquote><code>AllowOverride Limit FileInfo Indexes</code></blockquote>
<p>For full details on how to configure Apache for [% terms.Bugzilla %],
see the
<a href="[% docs_urlbase FILTER html %]configuration.html#http-apache">Configuration</a>
section of the [% terms.Bugzilla %] Guide.</p>
<h4>mod_perl</h4>
<p>If your [% terms.Bugzilla %] runs under mod_perl, the required Apache
configuration is now simpler. The line that used to look like:</p>
<blockquote><code>PerlSwitches -w -T -I/var/www/html/bugzilla
-I/var/www/html/bugzilla/lib</code></blockquote>
<p>Now should be only:</p>
<blockquote><code>PerlSwitches -w -T</code></blockquote>
<p>The <code>PerlConfigRequire</code> line should stay the same, however.</p>
<h3>New .htaccess file</h3>
<p>In previous versions of [% terms.Bugzilla %], there was a file
in [% terms.Bugzilla %]'s root directory called ".htaccess" that was
generated by <kbd>checksetup.pl</kbd>. This file is now shipped with
[%+ terms.Bugzilla %] instead of being generated during installation.</p>
<p>If you update via CVS or bzr, you will get a message that your existing
.htaccess file conflicts with the new one. You must
<strong>remove your existing .htaccess file</strong> and use the new one
instead. Continuing to use your old .htaccess file will cause certain new
features of [% terms.Bugzilla %] to not work properly, and may also lead
to security issues for your system in the future.</p>
<h2 id="v40_code_changes">Code Changes Which May Affect Customizations and
Extensions</h2>
<ul>
<li>In Extensions, if you want to serve files to the user via the web,
they must now be in a <kbd>web/</kbd> subdirectory of your Extension.
(For example, <kbd>extensions/Foo/web/</kbd>). <kbd>checksetup.pl</kbd>
sets permissions on extensions much more strictly now, and files in
other locations (such as your base <kbd>extensions/Foo/</kbd> directory)
will no longer be available to [% terms.Bugzilla %] users via the web
under certain configurations.</li>
<li>Previous versions of [% terms.Bugzilla %] used to allow putting a
single file into the "skins" directory and having that be an entire
skin. That is no longer allowed, and on upgrade, <kbd>checksetup.pl</kbd>
will convert any such skins into a directory with a single
<kbd>global.css</kbd> file in them.</li>
<li>When updating [% terms.bugs %], you should now use
<code>$bug->set_all</code> instead of using the individual
<kbd>set_</kbd> methods. In particular, <kbd>set_all</kbd> is now the
<em>only</em> way to set the product of [% terms.abug %]. See
<kbd>process_bug.cgi</kbd> for an example of how <kbd>set_all</kbd>
should be used.</li>
<li>You should not insert <script> tags and <link> CSS tags
into HTML anymore, in Extensions or in your customizations. Instead,
you should push new values into the <kbd>style_urls</kbd> or
<kbd>javascript_urls</kbd> parameters. If you have to insert manual
tags for some reason, be sure to call "FILTER mtime" on the URL. (Search
for other uses of "FILTER mtime" in the templates to see how it is
used.)</li>
<li>When calling <kbd>Bugzilla::BugMail::Send</kbd>, the "changer"
argument must now be a <kbd>Bugzilla::User</kbd> object, not just
a login name. The "owner" and "qacontact" arguments are still
just login names.</li>
<li>When creating a new subclass of Bugzilla::Object, you should no
longer use <kbd>UPDATE_VALIDATORS</kbd>. Also, in most cases you will
no longer need to override <kbd>run_create_validators</kbd>. Instead,
there is a new constant called
<a href="[% docs_urlbase FILTER html %]api/Bugzilla/Object.html#VALIDATOR_DEPENDENCIES">VALIDATOR_DEPENDENCIES</a>,
that specifies that certain fields have to be validated before other fields.
Then, all validators receive each already-validated value in a hash
as their fourth argument, so each validator can know the other values
that were passed in, while an object is being created. For an example of
how to use <kbd>VALIDATOR_DEPENDENCIES</kbd>, see
<kbd>Bugzilla/Field.pm</kbd>.</li>
<li>In previous versions of [% terms.Bugzilla %], you had to call
<code>Bugzilla->template_inner("")</code> after any time
that you called <kbd>template_inner</kbd> for a specific language.
It is no longer necessary to do this second <kbd>template_inner</kbd>
call.</li>
<li><kbd>post_bug.cgi</kbd> and <kbd>Bugzilla::Bug->create</kbd> now take
the <em>names</em> of groups instead of group ids.</li>
<li>Bugzilla::Bugmail now uses Bugzilla::Bug objects internally instead of
a lot of direct SQL.</li>
<li>For sending changes about [% terms.bugs %], there is now a method
called <kbd>send_changes</kbd> that you can call on Bugzilla::Bug
objects. For an example of its use, see <kbd>process_bug.cgi</kbd>.</li>
<li>The <kbd>Bugzilla::Search</kbd> class has been refactored, and should
now be easier to customize.</li>
<li>The <kbd>Bugzilla::Util::lsearch</kbd> function is gone. Use
<kbd>firstidx</kbd> from <kbd>List::MoreUtils</kbd>, instead.</li>
<li>[% terms.Bugzilla %] now includes YUI 2.8.2.</li>
<li><kbd>long_list.cgi</kbd>, <kbd>showattachment.cgi</kbd> and
<kbd>xml.cgi</kbd> are deprecated scripts which are no longer actively
used since [% terms.Bugzilla %] 2.19. These scripts will be removed in
[%+ terms.Bugzilla %] 4.2.</li>
