<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>

<p>If you are upgrading from a release before 4.0, make sure to read the
  release notes for all the <a href="#v42_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="v42_point">Updates in this 4.2.x Release</h2>

<h3>4.2.11</h3>

<p>This release fixes several security issues. See the
  <a href="https://www.bugzilla.org/security/4.0.14/">Security Advisory</a>
    for details.</p>

<h3>4.2.10</h3>

<p>This release fixes one security issue. See the
  <a href="https://www.bugzilla.org/security/4.0.13/">Security Advisory</a>
    for details.</p>

<h3>4.2.9</h3>

<p>This release fixes one regression introduced in [% terms.Bugzilla %] 4.2.8 by
  <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=968576">security [% terms.bug %] 968576</a>:
  URLs in [% terms.bug %] comments are displayed correctly again.
  (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=998323">[% terms.Bug %] 998323</a>)</p>

<h3>4.2.8</h3>

<p>This release fixes one minor security issue. See the
  <a href="https://www.bugzilla.org/security/4.0.11/">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> was incorrectly reporting DBI 1.630 (1.63) as
    being older than 1.614, preventing the upgrade to complete.
    If you still use Perl 5.10.0 or older, make sure you have the
    <a href="http://search.cpan.org/~jpeacock/version/lib/version.pod">version</a>
    module installed before running <kbd>checksetup.pl</kbd>.
    If you use Perl 5.10.1 or newer, this module is already available and
    no special action is required.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=938300">[% terms.Bug %] 938300</a>)</li>
  <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>The PROJECT environment variable is now correctly taken into account
    when mod_perl is enabled (this variable allows several installations to
    share the same codebase).
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=843457">[% terms.Bug %] 843457</a>)</li>
  <li>[% terms.Bugzilla %] no longer crashes when the <kbd>shutdownhtml</kbd>
    parameter is set and using a non-cookie based authentication method.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=748095">[% terms.Bug %] 748095</a>)</li>
  <li>The default date and time format used for SQLite has been fixed.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=938161">[% terms.Bug %] 938161</a>)</li>
</ul>

<h3>4.2.7</h3>

<p>In addition, the following [% terms.bugs %] have been fixed in this release:</p>

<ul>
  <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 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>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>
</ul>

<h3>4.2.6</h3>

<p>The following important fixes/changes have been made in this release:</p>

    when installing [% terms.Bugzilla %] for the first time.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=858911">[% terms.Bug %] 858911</a>)</li>
  <li>If a custom field depends on a product, component or classification,
    the "mandatory" bit was ignored on [% terms.bug %] creation.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=782210">[% terms.Bug %] 782210</a>)</li>
  <li>Queries involving flags were broken in several ways. These queries
    have been fixed.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=828344">[% terms.Bug %] 828344</a>)</li>
  <li>Tabular reports involving the empty resolution did not link [% terms.bug %]
    counts correctly.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=212471">[% terms.Bug %] 212471</a>)</li>
  <li>The <kbd>B[%%]ug.search</kbd> WebService 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.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=859118">[% terms.Bug %] 859118</a>)</li>
</ul>

<h3>4.2.5</h3>

<p>This release fixes one security issue. See the

  for details.</p>

<p>In addition, the following important fixes/changes have been made in this
  release:</p>

<ul>
  <li>Queries involving commenters were slow to return results. These queries
    have been optimized for better performance.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=818007">[% terms.Bug %] 818007</a>)</li>
  <li>It is no longer possible to create a new [% terms.bug %] using a disabled
    component, target milestone or version. These inactive values are also no
    longer accessible when moving [% terms.abug %] into another product.
    ([% terms.Bugs %] <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=752946">752946</a>
    and <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=840824">840824</a>)</li>
  <li>It was possible to create a new [% terms.bug %] with no description
    despite the status workflow required one for new [% terms.bugs %].
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=818890">[% terms.Bug %] 818890</a>)</li>
  <li>Custom multi-select fields are now available in the "Search By Change
    History" section of the "Advanced Search" page.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=839950">[% terms.Bug %] 839950</a>)</li>
  <li>A custom select field could have its list of values truncated if one
    or more of its values were disabled and the visibility of the values were
    controlled by another field.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=806809">[% terms.Bug %] 806809</a>)</li>
  <li>Warnings thrown by Return::Value 1.666002 about this deprecated module
    and which are polluting the web server error log are now disabled.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=826678">[% terms.Bug %] 826678</a>)</li>
</ul>

<h3>4.2.4</h3>

    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=788098">[% terms.Bug %] 788098</a>)</li>
  <li>Flag names were not properly escaped when displayed on the "confirm user
    match" page. An admin could unintentionally break the display of this page
    if a flag name contains a &lt; or &gt; character, because these characters
    were not filtered.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=790215">[% terms.Bug %] 790215</a>)</li>
  <li>We now prevent private WebServices methods from being called by external
    applications.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=793826">[% terms.Bug %] 793826</a>)</li>
  <li>PostgreSQL 9.2 requires DBD::Pg 2.19.3.

    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=780053">[% terms.Bug %] 780053</a>)</li>
  <li>Oracle was crashing when typing several bare words in the QuickSearch field.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=804505">[% terms.Bug %] 804505</a>)</li>
  <li>[% terms.Bugs %] with the resolution MOVED couldn't be edited anymore.

  <li>Editing dependencies from the "Change Several [% terms.Bugs %] at Once"
    page didn't work as expected. [% terms.Bug %] IDs were incorrectly parsed.

  <li>The "Actual Hours" axis now works correctly in tabular and graphical reports.

  <li>For improved security, we now send the "X-Content-Type-Options:&nbsp;nosniff"
    and "X-XSS-Protection:&nbsp;block" headers with every response.
    ([% terms.Bugs %] <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=671612">671612</a>
    and <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=680771">680771</a>)</li>
</ul>

<h3>4.2.3</h3>

  <li>It was possible to search on history for comments and attachments you
    cannot see (though these private comments and attachments are never disclosed).
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=779709">[% terms.Bug %] 779709</a>)</li>
  <li>PostgreSQL databases could be created with the wrong encoding despite

  <li>Scheduled whines could be sent at the wrong time on Oracle.

  <li>A regression in [% terms.Bugzilla %] 4.2 prevented classifications
    from being used in graphical and tabular reports in the "Multiple Tables"
    field.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=753688">[% terms.Bug %] 753688</a>)</li>
  <li>Attachments created by the <kbd>email_in.pl</kbd> script were associated
    to the wrong comment.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=762785">[% terms.Bug %] 762785</a>)</li>
  <li>Very long dependency lists can now be viewed correctly.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=762783">[% terms.Bug %] 762783</a>)</li>
  <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>

<h3>4.2.1</h3>

<p>This release fixes two security issues. See the
  <a href="https://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=58179,715270,730984,731163,737436,745320">

  <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>error_catch</kbd> has been added to let extensions
    alter the way errors are thrown.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=745197">[% terms.Bug %] 745197</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.

<h3 id="v42_req_apache">Optional Apache Modules</h3>

<p>If you are using Apache as your webserver, [% terms.Bugzilla %] can

  <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

  <li><a href="#v42_feat_wai">Accessibility Improvements</a></li>
  <li><a href="#v42_feat_other">Other Enhancements and Changes</a></li>
</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">
    [%- 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

  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=584742">
    [%- terms.Bug %] 584742</a>: When viewing [% terms.abug %], WebKit-based

    [%- terms.Bug %] 780053</a>: Oracle crashes when listing keywords, tags
    or flags in buglists.</li>
</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&mdash;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>

<h3>4.0.2</h3>

<p>This release fixes several security issues. See the
  <a href="https://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.
    ([% terms.Bugs %] <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=643910">643910</a>
    and <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=652165">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.
      (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=652381">[% terms.Bug %] 652381</a>)</li>

<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
  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>

<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="https://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="https://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="https://bugzillaupdate.wordpress.com/2010/07/06/bugzilla-4-0-has-a-new-default-status-workflow/">blog
  post about it</a> and the
  <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=486292">[% terms.bug %]
  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="https://bob.ippoli.to/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

  <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/docs/Web/HTTP/Headers/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/docs/Web/HTTP/Headers/X-Frame-Options"><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

  <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 &lt;Directory&gt; 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>&lt;Directory&gt;</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-&gt;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 &lt;script&gt; tags and &lt;link&gt; 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-&gt;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-&gt;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>
</ul>
