<h2><a name="v32_introduction"></a>Introduction</h2>

<p>Welcome to [% terms.Bugzilla %] 3.2! This is our first major feature
  release since [% terms.Bugzilla %] 3.0, and it brings a lot of great
  improvements and polish to the [% terms.Bugzilla %] experience.</p>

<p>If you're upgrading, make sure to read <a href="#v32_upgrading">How to
  Upgrade From An Older Version</a>. If you are upgrading from a release
  before 3.0, make sure to read the release notes for all the 
  <a href="#v32_previous">previous versions</a> in between your version
  and this one, <strong>particularly the "Notes For Upgraders" section of each
  version's release notes</strong>.</p>

<h2><a name="v32_point">Updates in this 3.2.x Release</a></h2>

<p>This section describes what's changed in the most recent b<!-- -->ug-fix
  releases of [% terms.Bugzilla %] after 3.2. We only list the
  most important fixes in each release. If you want a detailed list of
  <em>everything</em> that's changed in each version, you should use our
  <a href="http://www.bugzilla.org/status/changes.html">Change Log 
  Page</a>.</p>

<h3>3.2.3</h3>

<ul>
  <li>[% terms.Bugzilla %] is now compatible with MySQL 5.1.x versions 5.1.31
    and greater.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=480001">[% terms.Bug %] 480001</a>)</li>
  <li>On Windows, [% terms.Bugzilla %] sometimes would send mangled emails 
    (that would often fail to send).
  (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=467920">[% terms.Bug %] 467920</a>)</li>
  <li><code>recode.pl</code> would sometimes crash when trying to convert
    databases from older versions of [% terms.Bugzilla %].
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=431201">[% terms.Bug %] 431201</a>)</li>
  <li>Running a saved search with Unicode characters in its name would
    cause [% terms.Bugzilla %] to crash.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=477513">[% terms.Bug %] 477513</a>)</li>
  <li>[% terms.Bugzilla %] clients like Mylyn can now update [% terms.bugs %]
    again (the [% terms.bug %] XML format now contains a "token" element that
    can be used when updating a bug).
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=476678">[% terms.Bug %] 476678</a>)</li>
  <li>For installations using the <code>shadowdb</code> parameter, 
    [% terms.Bugzilla %] was accidentally writing to the "tokens" table
    in the shadow database (instead of the master database) when using the
    "Change Several [% terms.Bugs %] at Once" page.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=476943">[% terms.Bug  %] 476943</a>)</li>
</ul>

<p>This release also contains a security fix. See the
  <a href="#v32_security">Security Fixes Section</a> for details.</p>

<h3>3.2.2</h3>

<p>This release fixes one security issue that is critical for installations
  running 3.2.1 under mod_perl. See the 
  <a href="http://www.bugzilla.org/security/3.0.7/">Security Advisory</a>
  for details.</p>

<h3>3.2.1</h3>

<ul>
  <li>Attachments, charts, and graphs would sometimes be garbled on Windows.
  (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=464992">[% terms.Bug %] 464992</a>)</li>

  <li>Saving changes to parameters would sometimes fail silently (particularly
    on Windows when the web server didn't have the right permissions to
    update the <code>params</code> file). [% terms.Bugzilla %] will now
    throw an error in this case, telling you what is wrong.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=347707">[% terms.Bug %] 347707</a>)</li>

  <li>If you were using the <code>usemenuforusers</code> parameter,
    and [% terms.abug %] was assigned to (or had a QA Contact of) a disabled
    user, that field would be reset to the first user in the list when
    updating [% terms.abug %].
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=465589">[% terms.Bug %] 465589</a>)</li>

  <li>If you were using the <code>PROJECT</code> environment variable
    to have multiple [% terms.Bugzilla %] installations using one codebase,
    project-specific templates were being ignored. 
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=467324">[% terms.Bug %] 467324</a>)</li>

  <li>Some versions of the SOAP::Lite Perl module had a b[% %]ug that caused
    [%+ terms.Bugzilla %]'s XML-RPC service to break. 
    <code>checksetup.pl</code> now checks for these bad versions and 
    will reject them.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=468009">[% terms.Bug %] 468009</a>)</li>

  <li>The font sizes in various places were too small, when using the
    Classic skin.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=469136">[% terms.Bug %] 469136</a>)</li>
</ul>

<h2><a name="v32_security">Security Fixes In This 3.2.x Release</a></h2>

<h3>3.2.3</h3>

<p>This release fixes one security issue related to attachments. See the
  <a href="http://www.bugzilla.org/security/3.2.2/">Security Advisory</a>
  for details.</p>

<h3>3.2.2</h3>

<p>This release fixes one security issue that is critical for installations
  running 3.2.1 under mod_perl. See the 
  <a href="http://www.bugzilla.org/security/3.0.7/">Security Advisory</a> 
  for details.</p>

<h3>3.2.1</h3>

<p>This release contains several security fixes. One fix may break any
  automated scripts you have that are loading <kbd>process_bug.cgi</kbd>
  directly. We recommend that you read the entire 
  <a href="http://www.bugzilla.org/security/2.22.6/">Security Advisory</a>
  for this release.</p>

<h2><a name="v32_feat"></a>New Features and Improvements</h2>

<ul>
  <li><a href="#v32_feat_ui">Major UI Improvements</a></li>
  <li><a href="#v32_feat_skin">New Default Skin: Dusk</a></li>
  <li><a href="#v32_feat_status">Custom Status Workflow</a></li>

  <li><a href="#v32_feat_other">Other Enhancements and Changes</a></li>
</ul>

<h3><a name="v32_feat_ui"></a>Major UI Improvements</h3>

<p>[% terms.Bugzilla %] 3.2 has had some UI assistance from the NASA
  Human-Computer Interaction department and the new 
  <a href="http://wiki.mozilla.org/Bugzilla:UE">[% terms.Bugzilla %]
  User Interface Team</a>.</p>

<p>In particular, you will notice a massively redesigned [% terms.bug %]
  editing form, in addition to our <a href="#v32_feat_skin">new skin</a>.</p>

<h3><a name="v32_feat_skin"></a>New Default Skin: Dusk</h3>

<p>[% terms.Bugzilla %] 3.2 now ships with a skin called "Dusk" that is
  a bit more colorful than old default "Classic" skin.</p>

<p>Upgrading installations will still default to the "Classic" 
  skin--administrators can change the default in the Default Preferences
  control panel. Users can also choose to use the old skin in their
  Preferences (or using the View :: Page Style menu in Firefox).</p>

<p>The changes that [% terms.Bugzilla %] required for Dusk made
  [%+ terms.Bugzilla %] much easier to skin. See the
  <a href="http://wiki.mozilla.org/Bugzilla:Addons#Skins">Addons page</a>
  for additional skins, or try making your own!</p>

<h3><a name="v32_feat_status"></a>Custom Status Workflow</h3>

<p>You can now customize the list of statuses in [% terms.Bugzilla %],
  and transitions between them.</p>

<p>You can also specify that a comment must be made on certain transitions.</p>

<h3><a name="v32_feat_fields"></a>New Custom Field Types</h3>

<p>[% terms.Bugzilla %] 3.2 has support for three new types of
  custom fields:</p>

<ul>
  <li>Large Text: Adds a multi-line textbox to your [% terms.bugs %].</li>
  <li>Multiple Selection Box: Adds a box that allows you to choose
    multiple items from a list.</li>
  <li>Date/Time: Displays a date and time, along with a JavaScript
    calendar popup to make picking a date easier.</li>
</ul>

<h3><a name="v32_feat_install"></a>Easier Installation</h3>

<p>[% terms.Bugzilla %] now comes with a script called 
  <kbd>install-module.pl</kbd> that can automatically download
  and install all of the required Perl modules for [% terms.Bugzilla %].
  It stores them in a directory inside your [% terms.Bugzilla %]
  installation, so you can use it even if you don't have administrator-level
  access to your machine, and without modifying your main Perl install.</p>

<p><kbd>checksetup.pl</kbd> will print out instructions for using
  <kbd>install-module.pl</kbd>, or you can read its
  <a href="[% docs_urlbase FILTER html %]api/install-module.html">documentation</a>.</p>

<h3><a name="v32_feat_oracle"></a>Experimental Oracle Support</h3>

<p>[% terms.Bugzilla %] 3.2 contains experimental support for using 
  Oracle as its database. Some features of [% terms.Bugzilla %] are known 
  to be broken on Oracle, but hopefully will be working by our next major
  release.</p>

<p>The [% terms.Bugzilla %] Project, as an open-source project, of course
  does not recommend the use of proprietary database solutions. However,
  if your organization requires that you use Oracle, this will allow
  you to use [% terms.Bugzilla %]!</p>

<p>The [% terms.Bugzilla %] Project thanks Oracle Corp. for their extensive
  development contributions to [% terms.Bugzilla %] which allowed this to 
  happen!</p>

<h3><a name="v32_feat_utf8"></a>Improved UTF-8 Support</h3>

<p>[% terms.Bugzilla %] 3.2 now has advanced UTF-8 support in its code,
  including correct handling for truncating and wrapping multi-byte
  languages. Major issues with multi-byte or unusual languages
  are now resolved, and [% terms.Bugzilla %] should now be usable
  by users in every country with little (or at least much less)
  customization.</p>

<h3><a name="v32_feat_grcons"></a>Group Icons</a></h3>

<p>Administrators can now specify that users who are in certain groups
  should have an icon appear next to their name whenever they comment.
  This is particularly useful for distinguishing developers from 
  [%+ terms.bug %] reporters.</p>

<h3><a name="v32_feat_other"></a>Other Enhancements and Changes</h3>

<p>These are either minor enhancements, or enhancements that have
  very short descriptions. Some of these are very useful, though!</p>

<h4>Enhancements For Users</h4>

<ul>
  <li><strong>[% terms.Bugs %]</strong>: You can now reassign
    [%+ terms.abug %] at the same time as you are changing its status.</li>
  <li><strong>[% terms.Bugs %]</strong>: When entering [% terms.abug %], 
    you will now see the description of a component when you select it.</li>
  <li><strong>[% terms.Bugs %]</strong>: The [% terms.bug %] view now 
    contains some <a href="http://microformats.org/about/">Microformats</a>,
    most notably for users' names and email addresses.</li>
  <li><strong>[% terms.Bugs %]</strong>: You can now remove a QA Contact
    from [% terms.abug %] simply by clearing the QA Contact field.</li>
  <li><strong>[% terms.Bugs %]</strong>: There is now a user preference 
    that will allow you to exclude the quoted text when replying 
    to comments.</li>
  <li><strong>[% terms.Bugs %]</strong>: You can now expand or collapse
    individual comments in the [% terms.bug %] view.</li>

  <li><strong>Attachments</strong>: There is now "mid-air collision" 
      protection when editing attachments.</li>
  <li><strong>Attachments</strong>: Patches in the Diff Viewer now show 
    line numbers (<a href="https://bugzilla.mozilla.org/attachment.cgi?id=327546">Example</a>).</li>
  <li><strong>Attachments</strong>: After creating or updating an attachment,
    you will be immediately shown the [% terms.bug %] that the attachment
    is on.</li>

  <li><strong>Search</strong>: You can now reverse the sort of 
    [%+ terms.abug %] list by clicking on a column header again.</li>
  <li><strong>Search</strong>: Atom feeds of [% terms.bug %] lists now
    contain more fields.</li>
  <li><strong>Search</strong>: QuickSearch now supports searching flags
    and groups. It also now includes the OS field in the list of fields
    it searches by default.</li>
  <li><strong>Search</strong>: "Help" text can now appear on query.cgi 
    for Internet Explorer and other non-Firefox browsers. (It always
    could appear for Firefox.)</li>

  <li>[% terms.Bugzilla %] now ships with an icon that will show
    up next to the URL in most browsers. If you want to replace it,
    it's in <kbd>images/favicon.ico</kbd>.</li>

  <li>You can now set the Deadline when using "Change Several 
    [%+ terms.Bugs %] At Once"</li>
  <li><strong>Saved Searches</strong> now save their column list, so if 
    you customize the list of columns and save your search, it will 
    always contain those columns.</li>
  <li><strong>Saved Searches</strong>: When you share a search, you can
    now see how many users have subscribed to it, on 
    <kbd>userprefs.cgi</kbd>.</li>
  <li><strong>Saved Searches</strong>: You can now see what group a 
    shared search was shared to, on the list of available shared searches
    in <kbd>userprefs.cgi</kbd>.</li>
  <li><strong>Flags</strong>: If your installation uses drop-down user 
    lists, the flag requestee box will now contain only users who are 
    actually allowed to take requests.</li>
  <li><strong>Flags</strong>: If somebody makes a request to you, and you
    change the requestee to somebody else, the requester is no longer set
    to you. In other words, you can "redirect" requests and maintain the
    original requester.</li>
  <li><strong>Flags</strong>: Emails about flags now will thread properly
    in email clients to be a part of [% terms.abug %]'s thread.</li>
  <li>When using <kbd>email_in.pl</kbd>, you can now add users to the CC
    list by just using <kbd>@cc</kbd> as the field name.</li>
  <li>Many pages (particularly administrative pages) now contain links to
    the relevant section of the [% terms.Bugzilla %] Guide, so you can read 
    the documentation for that page.</li>
  <li>Dependency Graphs should render more quickly, as they now (by default)
    only include the same [% terms.bugs %] that you'd see in the dependency
    tree.</li>
</ul>

<h4>Enhancements For Administrators</h4>

<ul>
  <li><strong>Admin UI</strong>: Instead of having the Administration 
    Control Panel links in the footer, there is now just one link called 
   "Administration" that takes you to a page that links to all the
    administrative controls for [% terms.Bugzilla %].</li>
  <li><strong>Admin UI</strong>: Administrative pages no longer display
    confirmation pages, instead they redirect you to some useful page 
    and display a message about what changed.</li>
  <li><strong>Admin UI</strong>: The interface for editing group 
     inheritance in <kbd>editgroups.cgi</kbd> is much clearer now.</li>
  <li><strong>Admin UI</strong>: When editing a user, you can now see 
    all the components where that user is the Default Assignee or Default
    QA Contact.</li>

  <li><strong>Email</strong>: For installations that use SMTP to send 
    mail (as opposed to Sendmail), [%+ terms.Bugzilla %] now supports
    SMTP Authentication, so that it can log in to your mail server 
    before sending messages.</li>
  <li><strong>Email</strong>: Using the "Test" mail delivery method now
     creates a valid mbox file to make testing easier.</li>

  <li><strong>Authentication</strong>: [% terms.Bugzilla %] now correctly 
    handles LDAP records which contain multiple email addresses. (The first
    email address in the list that is a valid [% terms.Bugzilla %] account 
    will be used, or if this is a new user, the first email address in 
    the list will be used.)</li>
  <li><strong>Authentication</strong>: [% terms.Bugzilla %] can now take 
    a list of LDAP servers to try in order until it gets a successful
    connection.</li>
  <li><strong>Authentication</strong>: [% terms.Bugzilla %] now supports 
    RADIUS authentication.</li>

  <li><strong>Security</strong>: The login cookie is now created as 
    "HTTPOnly" so that it can't be read by possibly malicious scripts. 
    Also, if SSL is enabled on your installation, the login cookie is
    now only sent over SSL connections.</li>
  <li><strong>Security</strong>: The <code>ssl</code> parameter now protects
    every page a logged-in user accesses, when set to "authenticated sessions."
    Also, SSL is now enforced appropriately in the WebServices interface when
    the parameter is set.</li>

  <li><strong>Database</strong>: [% terms.Bugzilla %] now uses transactions in 
    the database instead of table locks. This should generally improve
    performance with many concurrent users. It also means if there is
    an unexpected error in the middle of a page, all database changes made
    during that page will be rolled back.</li>
  <li><strong>Database</strong>: You no longer have to set 
    <code>max_packet_size</code> in MySQL to add large attachments. However,
    you may need to set it manually if you restore a mysqldump into your
    database.</li>

  <li>New WebService functions:
    <a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Bug.html">B<!-- -->ug.add_comment</a>
    and <a href="[% docs_urlbase FILTER html %]api/Bugzilla/WebService/Bugzilla.html">Bugzilla.extensions</a>.</li>

  <li>You can now delete custom fields, but only if they have never been
    set on any [% terms.bug %].</li>
  <li>There is now a <kbd>--reset-password</kbd> argument to 
    <kbd>checksetup.pl</kbd> that allows you to reset a user's password
    from the command line.</li>
  <li>There is now a script called <kbd>sanitycheck.pl</kbd> that you can
    run from the command line. It works just like <kbd>sanitycheck.cgi</kbd>.
    By default, it only outputs anything if there's an error, so it's
    ideal for administrators who want to run it nightly in a cron job.</li>
  <li>The <kbd>strict_isolation</kbd> parameter now prevents you from setting
    users who cannot see [% terms.abug %] as a CC, Assignee, or QA
    Contact. Previously it only prevented you from adding users who
    could not <em>edit</em> the [% terms.bug %].</li>
  <li>Extensions can now add their own headers to the HTML &lt;head&gt;
    for things like custom CSS and so on.</li>
  <li><kbd>sanitycheck.cgi</kbd> has been templatized, meaning that the
    entire [% terms.Bugzilla %] UI is now contained in templates.</li>
  <li>When setting the <kbd>sslbase</kbd> parameter, you can now specify
    a port number in the URL.</li>
  <li>When importing [% terms.bugs %] using <kbd>importxml.pl</kbd>,
    attachments will have their actual creator set as their creator,
    instead of the person who exported the [% terms.bug %] from the other
    system.</li>
  <li>The voting system is off by default in new installs. This is to
    prepare for the fact that it will be moved into an extension at
    some point in the future.</li>
  <li>The <code>shutdownhtml</code> parameter now works even when 
    [% terms.Bugzilla %]'s database server is down.</li>
</ul>

<h3>Enhancements for Localizers (or Localized Installations)</h3>

<ul>
  <li>The documentation can now be localized--in other words, you can have
    documentation installed for multiple languages at once and
    [%+ terms.Bugzilla %] will link to the correct language in its internal
    documentation links.</li>
  <li>[% terms.Bugzilla %] no longer uses the <kbd>languages</kbd> parameter.
    Instead it reads the <kbd>template/</kbd> directory to see which
    languages are available.</li>
  <li>Some of the messages printed by <kbd>checksetup.pl</kbd> can now
    be localized. See <kbd>template/en/default/setup/strings.txt.pl</kbd>.
</ul>

<h2><a name="v32_issues"></a>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=69621">
    [%- terms.Bug %] 69621</a>: If you rename or remove a keyword that is
    in use on [% terms.bugs %], you will need to rebuild the "keyword cache"
    by running <a href="sanitycheck.cgi">sanitycheck.cgi</a> and choosing 
    the option to rebuild the cache when it asks. Otherwise keywords may 
    not show up properly in search results.</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>
  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370370">

<h3><a name="v32_upgrading_notes"></a>Notes For Upgraders</h3>

<ul>
  <li>If you upgrade by CVS, the <kbd>extensions</kbd> and 
    <kbd>skins/contrib</kbd> directories are now in CVS instead of
    being created by <kbd>checksetup.pl</kbd> If you do a <kbd>cvs update</kbd>
    from 3.0, you will be told that your directories are "in the way" and
    you should delete (or move) them and then do <kbd>cvs update</kbd>
    again. Also, the <kbd>docs</kbd> directory has been restructured
    and after you <kbd>cvs update</kbd> you can delete the <kbd>docs/html</kbd>,
    <kbd>docs/pdf</kbd>, <kbd>docs/txt</kbd>, and <kbd>docs/xml</kbd>
    directories.</li>
  <li>If you are using MySQL, you should know that [% terms.Bugzilla %]
    now uses InnoDB for all tables. <kbd>checksetup.pl</kbd> will convert
    your tables automatically, but if you have InnoDB disabled,
    the upgrade will not be able to complete (and <kbd>checksetup.pl</kbd>
    will tell you so).</li>

  <li><strong>You should also read the 
    <a href="#v30_upgrading_notes">[% terms.Bugzilla %] 3.0 Notes For Upgraders
    section</a> of the 
    <a href="#v32_previous">previous release notes</a> if you are upgrading
    from a version before 3.0.</strong></li>
</ul>

<h2><a name="v32_code_changes"></a>Code Changes Which May Affect 
  Customizations</h2>

<ul>
  <li><a href="#v32_code_hooks">More Hooks!</a></li>
  <li><a href="#v32_code_search">Search.pm Rearchitecture</a></li>
  <li><a href="#v32_code_lib">lib Directory</a></li>
  <li><a href="#v32_code_other">Other Changes</a></li>
</ul>

<h3><a name="v32_code_hooks"></a>More Hooks!</h3>

<p>There are more code hooks in 3.2 than there were in 3.0. See the
  documentation of <a href="[% docs_urlbase FILTER html %]api/Bugzilla/Hook.html">Bugzilla::Hook</a>
  for more details.</p>

<h3><a name="v32_code_search"></a>Search.pm Rearchitecture</h3>

<p><kbd>Bugzilla/Search.pm</kbd> has been heavily modified, to be much
  easier to read and use. It contains mostly the same code as it did in
  3.0, but it has been moved around and reorganized significantly.</p>

<h3><a name="v32_code_lib"></a>lib Directory</h3>

<p>As part of implementing <a href="#v32_feat_install">install-module.pl</a>,
  [%+ terms.Bugzilla %] was given a local <kbd>lib</kbd> directory which
  it searches for modules, in addition to the standard system path.</p>

<p>This means that all [% terms.Bugzilla %] scripts now start with
  <code>use lib qw(. lib);</code> as one of the first lines.</p>

<h3><a name="v32_code_other"></a>Other Changes</h3>

<ul>
  <li>You should now be using <code>get_status('NEW')</code> instead of
    <code>status_descs.NEW</code> in templates.</li>
  <li>The <code>[&#37;# version = 1.0 &#37;]</code> comment at the top of every
    template file has been removed.</li>

<h2><a name="v30_introduction"></a>Introduction</h2>

<p>Welcome to [% terms.Bugzilla %] 3.0! It's been over eight years since
  we released [% terms.Bugzilla %] 2.0, and everything has changed since
  then. Even just since our previous release, [% terms.Bugzilla %] 2.22,
  we've added a <em>lot</em> of new features. So enjoy the release, we're
  happy to bring it to you.</p>

<p>If you're upgrading, make sure to read <a href="#v30_upgrading">How to
  Upgrade From An Older Version</a>. If you are upgrading from a release
  before 2.22, make sure to read the release notes for all the 
  <a href="#v30_previous">previous versions</a> in between your version 
  and this one.</p>

<h2><a name="v30_point">Updates in this 3.0.x Release</a></h2>

<p>This section describes what's changed in the most recent b<!-- -->ug-fix
  releases of [% terms.Bugzilla %] after 3.0. We only list the
  most important fixes in each release. If you want a detailed list of
  <em>everything</em> that's changed in each version, you should use our
  <a href="http://www.bugzilla.org/status/changes.html">Change Log Page</a>.</p>

<h3>3.0.6</h3>

<ul>
  <li>Before 3.0.6, unexpected fatal WebService errors would result in
    a <code>faultCode</code> that was a string instead of a number.
   (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=446327">[% terms.Bug %] 446327</a>)</li>
  <li>If you created a product or component with the same name as one you
    previously deleted, it would fail with an error about the series table.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=247936">[% terms.Bug %] 247936</a>)</li>
</ul>

<p>See also the <a href="#v30_security">Security Advisory</a> section for
  information about a security issue fixed in this release.</p>

<h3>3.0.5</h3>

<ul>
  <li>If you don't have permission to set a flag, it will now appear
    unchangeable in the UI.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=433851">[% terms.Bug %] 433851</a>)</li>
  <li>If you were running mod_perl, [% terms.Bugzilla %] was not correctly
    closing its connections to the database since 3.0.3, and so sometimes
    the DB would run out of connections.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=441592">[% terms.Bug %] 441592</a>)</li>
  <li>The installation script is now clear about exactly which 
    <code>Email::</code> modules are required in Perl, thus avoiding the
    problem where emails show up with a body like 
    <samp>SCALAR(0xBF126795)</samp>.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=441541">[% terms.Bug %] 441541</a>)</li>
  <li><a href="[% docs_urlbase FILTER html %]api/email_in.html">email_in.pl</a>
    is no longer case-sensitive for values of <kbd>@product</kbd>.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365697">[% terms.Bug %] 365697</a>)</li>
</ul>

<p>See also the <a href="#v30_security">Security Advisory</a> section for
  information about security issues fixed in this release.</p>

<h3>3.0.4</h3>

<ul>
  <li>[% terms.Bugzilla %] administrators were not being correctly notified
    about new releases.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=414726">[% terms.Bug %] 414726</a>)</li>

  <li>There could be extra whitespace in email subject lines.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=411544">[% terms.Bug %] 411544</a>)</li>

  <li>The priority, severity, OS, and platform fields were always required by
    the <kbd>B<!-- -->ug.create</kbd> WebService function, even if they had
    defaults specified.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=384009">[% terms.Bug %] 384009</a>)</li>

  <li>Better threading of [% terms.bug %]mail in some email clients.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=376453">[% terms.Bug %] 376453</a>)</li>

  <li>There were many fixes to the Inbound Email Interface 
    (<kbd>email_in.pl</kbd>).
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=92274">[% terms.Bug %] 92274</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=377025">[% terms.Bug %] 377025</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=412943">[% terms.Bug %] 412943</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=413672">[% terms.Bug %] 413672</a>, and
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=431721">[% terms.Bug %] 431721</a>)</li>

  <li>checksetup.pl now handles UTF-8 conversion more reliably during upgrades.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=374951">[% terms.Bug %] 374951</a>)</li>

  <li>Comments written in CJK languages are now correctly word-wrapped.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=388723">[% terms.Bug %] 388723</a>)</li>

  <li>All emails will now be sent in the correct language, when the user
    has chosen a language for emails.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=405946">[% terms.Bug %] 405946</a>)

  <li>On Windows, temporary files created when uploading attachments are now
    correctly deleted when the upload is complete.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=414002">[% terms.Bug %] 414002</a>)</li>

  <li><kbd>checksetup.pl</kbd> now prints correct installation instructions
    for Windows users using Perl 5.10.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=414430">[% terms.Bug %] 414430</a>)
</ul>

<p>See also the <a href="#v30_security">Security Advisory</a> section for
  information about security issues fixed in this release.</p>

<h3>3.0.3</h3>

<ul>
  <li>mod_perl no longer compiles [% terms.Bugzilla %]'s code for each Apache
    process individually. It now compiles code only once and shares it among
    each Apache process. This greatly improves performance and highly 
    decreases the memory footprint.
   (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=398241">[% terms.Bug %] 398241</a>)</li>

  <li>You can now search for '---' (without quotes) in versions and milestones.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=362436">[% terms.Bug %] 362436</a>)</li>

  <li>[% terms.Bugzilla %] should no longer break lines unnecessarily in 
    email subjects. This was causing trouble with some email clients.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=374424">[% terms.Bug %] 374424</a>)</li>

  <li>If you had selected "I'm added to or removed from this capacity" option
    for the "CC" role in your email preferences, you wouldn't get mail when
    more than one person was added to the CC list at once.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=394796">[% terms.Bug %] 394796</a>)</li>

  <li>Deleting a user account no longer deletes whines from another user who
    has the deleted account as addressee. The schedule is simply removed, 
    but the whine itself is left intact.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=395924">[% terms.Bug %] 395924</a>)</li>

  <li><kbd>contrib/merge-users.pl</kbd> now correctly merges all required
    fields when merging two user accounts.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=400160">[% terms.Bug %] 400160</a>)</li>

  <li>[% terms.Bugzilla %] no longer requires Apache::DBI to run under 
    mod_perl. It caused troubles such as lost connections with the DB and
    didn't give any important performance gain.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=408766">[% terms.Bug %] 408766</a>)</li>
</ul>

<h3>3.0.2</h3>

<ul>
  <li>[% terms.Bugzilla %] should now work on Perl 5.9.5 (and thus the
    upcoming Perl 5.10.0).
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=390442">[% terms.Bug %] 390442</a>)</li>
</ul>

<p>See also the <a href="#v30_security">Security Advisory</a> section for
  information about an important security issue fixed in this release.</p>

<h3>3.0.1</h3>

<ul>
  <li>For users of Firefox 2, the <code>show_bug.cgi</code> user interface
    should no longer "collapse" after you modify [% terms.abug %].
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370739">[% terms.Bug %] 370739</a>)</li>
  <li>If you can bless a group, and you share a saved search with that
    group, it will no longer automatically appear in all of that group's
    footers unless you specifically request that it automatically appear
    in their footers.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365890">[% terms.Bug %] 365890</a>)</li>
  <li>There is now a parameter to allow users to perform searches without
    any search terms. (In other words, to search for just a Product
    and Status on the Simple Search page.) The parameter is called
    <code>specific_search_allow_empty_words</code>.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=385910">[% terms.Bug %] 385910</a>)</li>
  <li>If you attach a file that has a MIME-type of <code>text/x-patch</code>
    or <code>text/x-diff</code>, it will automatically be treated as a 
    patch by [% terms.Bugzilla %].
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365756">[% terms.Bug %] 365756</a>)</li>
  <li>Dependency Graphs now work correctly on all mod_perl installations.
    There should now be no remaining signficant problems with running
    [%+ terms.Bugzilla %] under mod_perl.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370398">[% terms.Bug %] 370398</a>)</li>
  <li>If moving [% terms.abug %] between products would remove groups
    from the [% terms.bug %], you are now warned.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=303183">[% terms.Bug %] 303183</a>)</li>
  <li>On IIS, whenever [% terms.Bugzilla %] threw a warning, it would
    actually appear on the web page. Now warnings are suppressed,
    unless you have a file in the <code>data</code> directory called
    <code>errorlog</code>, in which case warnings will be printed there.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=390148">[% terms.Bug %] 390148</a>)</li>
  <li>If you used <kbd>email_in.pl</kbd> to edit [% terms.abug %] that was
    protected by groups, all of the groups would be cleared.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=385453">[% terms.Bug %] 385453</a>)</li>
  <li>PostgreSQL users: New Charts were failing to collect data over time.
    They will now start collecting data correctly.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=257351">[% terms.Bug %] 257351</a>)</li>
  <li>Some flag mails didn't specify who the requestee was. 
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=379787">[% terms.Bug %] 379787</a>)</li>
  <li>Instead of throwing real errors, <kbd>collectstats.pl</kbd> would
    just say that it couldn't find <code>ThrowUserError</code>.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=380709">[% terms.Bug %] 380709</a>)</li>
  <li>Logging into [% terms.Bugzilla %] from the home page works again
    with IIS5. 
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=364008">[% terms.Bug %] 364008</a>)</li>
  <li>If you were using SMTP for sending email, sometimes emails would
    be missing the <code>Date</code> header.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=304999">[% terms.Bug %] 304999</a>).</li>
  <li>In the XML-RPC WebService, <code>B<!-- -->ug.legal_values</code> now
    correctly returns values for custom fields if you request values 
    for custom fields.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=381737">[% terms.Bug %] 381737</a>)</li>
  <li>The "[% terms.Bug %]-Writing Guidelines" page has been shortened
    and re-written.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=378590">[% terms.Bug %] 378590</a>)</li>
  <li>If your <code>urlbase</code> parameter included a port number,
    like <code>www.domain.com:8080</code>, SMTP might have failed.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=384501">[% terms.Bug %] 384501</a>)</li>
  <li>For SMTP users, there is a new parameter, <code>smtp_debug</code>.
    Turning on this parameter will log the full information about
    every SMTP session to your web server's error log, to help with
    debugging issues with SMTP.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=384497">[% terms.Bug %] 384497</a>)</li>
  <li>If you are a "global watcher" (you get all mails from every 
    [% terms.bug %]), you can now see that in your Email Preferences.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365302">[% terms.Bug %] 365302</a>)</li>
  <li>The Status and Resolution of [% terms.bugs %] are now correctly
    localized in CSV search results.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=389517">[% terms.Bug %] 389517</a>)</li>
  <li>The "Subject" line of an email was being mangled if it contained
    non-Latin characters.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=387860">[% terms.Bug %] 387860</a>)</li>
  <li>Editing the "languages" parameter using <kbd>editparams.cgi</kbd> would
    sometimes fail, causing [% terms.Bugzilla %] to throw an error.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=335354">[% terms.Bug %] 335354</a>)</li>

</ul>

<h3><a name="v30_feat_cf"></a>Custom Fields</h3>

<p>[% terms.Bugzilla %] now includes very basic support for custom fields.</p>

<p>Users in the <kbd>admin</kbd> group can add plain-text or drop-down
  custom fields. You can edit the values available for drop-down fields
  using the &quot;Field Values&quot; control panel.</p>

<p>Don't add too many custom fields! It can make [% terms.Bugzilla %]
  very difficult to use. Try your best to get along with the default
  fields, and then if you find that you can't live without custom fields
  after a few weeks of using [% terms.Bugzilla %], only then should you
  start your custom fields.</p>

<h3><a name="v30_feat_mp"></a>mod_perl Support</h3>

<p>[% terms.Bugzilla %] 3.0 supports mod_perl, which allows for extremely
  enhanced page-load performance. mod_perl trades memory usage for performance,
  allowing near-instantaneous page loads, but using much more memory.</p>

<p>If you want to enable mod_perl for your [% terms.Bugzilla %], we recommend
  a minimum of 1.5GB of RAM, and for a site with heavy traffic, 4GB to 8GB.</p>

<p>If performance isn't that critical on your installation, you don't
  have the memory, or you are running some other web server than
  Apache, [% terms.Bugzilla %] still runs perfectly as a normal CGI
  application, as well.</p>

<h3><a name="v30_feat_sq"></a>Shared Saved Searches</h3>

<p>Users can now choose to &quot;share&quot; their saved searches
  with a certain group. That group will then be able to 
  &quot;subscribe&quot; to those searches, and have them appear
  in their footer.</p>

<p>If the sharer can &quot;bless&quot; the group he's sharing to,
  (that is, if he can add users to that group), it's considered
  that he's a manager of that group, and his queries show up
  automatically in that group's footer (although they can
  unsubscribe from any particular search, if they want.)</p>

<p>In order to allow a user to share their queries, they also
  have to be a member of the group specified in the 
  <code>querysharegroup</code> parameter.</p>

<p>Users can control their shared and subscribed queries from
  the &quot;Preferences&quot; screen.</p>

<h3><a name="v30_feat_afn"></a>Attachments and Flags on New 
  [% terms.Bugs %]</h3>

<p>You can now add an attachment while you are filing a new 
  [% terms.bug %].</p>

<p>You can also set flags on the [% terms.bug %] and on attachments, while
  filing a new [% terms.bug %].</p>

<h3><a name="v30_feat_cr"></a>Custom Resolutions</h3>

<p>You can now customize the list of resolutions available
  in [% terms.Bugzilla %], including renaming the default resolutions.</p>

<p>The resolutions <code>FIXED</code>, <code>DUPLICATE</code>
  and <code>MOVED</code> have a special meaning to [% terms.Bugzilla %],
  though, and cannot be renamed or deleted.</p>

<h3><a name="v30_feat_ppp"></a>Per-Product Permissions</h3>

<p>You can now grant users <kbd>editbugs</kbd> and <kbd>canconfirm</kbd>
  for only certain products. You can also grant users <kbd>editcomponents</kbd>
  on a product, which means they will be able to edit that product
  including adding/removing components and other product-specific
  controls.</p>

<h3><a name="v30_feat_ui"></a>User Interface Improvements</h3>

<p>There has been some work on the user interface for [% terms.Bugzilla %] 3.0,
  including:</p>

<ul>
  <li>There is now navigation and a search box a the <em>top</em> of
    each page, in addition to the bar at the bottom of the page.</li>
  <li>A re-designed &quot;Format for Printing&quot; page for 
    [% terms.bugs %].</li>
  <li>The layout of <kbd>show_bug.cgi</kbd> (the [% terms.bug %] editing 
    page) has been changed, and the attachment table has been redesigned.</li>
</ul>

<h3><a name="v30_feat_xml"></a>XML-RPC Interface</h3>

<p>[% terms.Bugzilla %] now has a Web Services interface using the XML-RPC
  protocol. It can be accessed by external applications by going
  to the <kbd>xmlrpc.cgi</kbd> on your installation.</p>

<p>Documentation can be found in the 
  <a href="[% docs_urlbase FILTER html %]api/">[% terms.Bugzilla %] 
  API Docs</a>, in the various <kbd>Bugzilla::WebService</kbd> modules.</p>

<h3><a name="v30_feat_skin"></a>Skins</h3>

<p>[% terms.Bugzilla %] can have multiple &quot;skins&quot; installed,
  and users can pick between them. To write a skin, you just have to
  write several CSS files. See the <a href="[% docs_urlbase FILTER html %]cust-skins.html">Custom
  Skins Documentation</a> for more details.</p>

<p>We currently don't have any alternate skins shipping with
  [% terms.Bugzilla %]. If you write an alternate skin, please
  let us know!</p>

<h3><a name="v30_feat_sbu"></a>Unchangeable Fields Appear
  Unchangeable</h3>

<p>As long as you are logged in, when viewing [% terms.abug %], if you 
  cannot change a field, it will not look like you can change it. That 
  is, the value will just appear as plain text.</p>

<h3><a name="v30_feat_et"></a>All Emails in Templates</h3>

<p>All outbound emails are now controlled by the templating system.
  What used to be the <code>passwordmail</code>, <code>whinemail</code>,
  <code>newchangedmail</code> and <code>voteremovedmail</code>
  parameters are now all templates in the <kbd>template/</kbd> directory.</p>

<p>This means that it's now much easier to customize your outbound
  emails, and it's also possible for localizers to have more
  localized emails as part of their language packs, if they want.</p>

<p>We also added a <code>mailfrom</code> parameter to let you set
  who shows up in the <code>From</code> field on all emails that
  [%+ terms.Bugzilla %] sends.</p>

<h3><a name="v30_feat_df"></a>No More Double-Filed [% terms.Bugs %]</h3>

<p>Users of [% terms.Bugzilla %] will sometimes accidentally submit 
  [% terms.abug %] twice, either by going back in their web browser, 
  or just by refreshing a page. In the past, this could file the same 
  [% terms.bug %] twice (or even three times) in a row, irritating 
  developers and confusing users.</p>

<p>Now, if you try to submit [% terms.abug %] twice from the same screen 
  (by going back or by refreshing the page), [% terms.Bugzilla %] will warn 
  you about what you're doing, before it actually submits the duplicate
  [%+ terms.bug %].</p>

<h3><a name="v30_feat_cc"></a>Default CC List for Components</h3>

<p>You can specify a list of users who will <em>always</em> be added to
  the CC list of new [% terms.bugs %] in a component.</p>

<h3><a name="v30_feat_emi"></a>File/Modify [% terms.Bugs %] By Email</h3>

<p>You can now file or modify [% terms.bugs %] via email. Previous versions
  of [% terms.Bugzilla %] included this feature only as an
  unsupported add-on, but it is now an official interface to
  [%+ terms.Bugzilla %].</p>

<p>For more details see the <a href="[% docs_urlbase FILTER html %]api/email_in.html">documentation
  for email_in.pl</a>.</p>

<h3><a name="v30_feat_gw"></a>Users Who Get All [% terms.Bug %] 
  Notifications</h3>

<p>There is now a parameter called <kbd>globalwatchers</kbd>. This
  is a comma-separated list of [% terms.Bugzilla %] users who will
  get all [% terms.bug %] notifications generated by [% terms.Bugzilla %].</p>

<p>Group controls still apply, though, so users who can't see [% terms.abug %]
  still won't get notifications about that [% terms.bug %].</p>

<h3><a name="v30_feat_utf8"></a>Improved UTF-8 Support</h3>

<p>[% terms.Bugzilla %] users running MySQL should now have excellent
  UTF-8 support if they turn on the <kbd>utf8</kbd> parameter. (New
  installs have this parameter on by default.) [% terms.Bugzilla %]
  now correctly supports searching and sorting in non-English languages,
  including multi-bytes languages such as Chinese.</p>

<h3><a name="v30_feat_upda"></a>Automatic Update Notification</h3>

<p>If you belong to the <kbd>admin</kbd> group, you will be notified
  when you log in if there is a new release of [% terms.Bugzilla %]
  available to download.</p>

<p>You can control these notifications by changing the 
  <kbd>upgrade_notification</kbd> parameter.</p>

<p>If your [% terms.Bugzilla %] installation is on a machine that needs to go
  through a proxy to access the web, you may also have to set the
  <kbd>proxy_url</kbd> parameter.</p>

<h3><a name="v30_feat_welc"></a>Welcome Page for New Installs</h3>

<p>When you log in for the first time on a brand-new [% terms.Bugzilla %]
  installation, you will be presented with a page that describes
  where you should go from here, and what parameters you should set.</p>

<h3><a name="v30_feat_qs"></a>QuickSearch Plugin for IE7 and Firefox 2</h3>

<p>Firefox 2 users and Internet Explorer 7 users will be presented
  with the option to add [% terms.Bugzilla %] to their search bar.
  This uses the 
  <a href="page.cgi?id=quicksearch.html">QuickSearch syntax</a>.</p>

<h3><a name="v30_feat_other"></a>Other Enhancements and Changes</h3>

<p>These are either minor enhancements, or enhancements that have
  very short descriptions. Some of these are very useful, though!</p>

<h4>Enhancements That Affect [% terms.Bugzilla %] Users</h4>

<ul>
  <li>In comments, quoted text (lines that start with <kbd>&gt;</kbd>)
    will be a different color from normal text.</li>
  <li>There is now a user preference that will add you to the CC list
    of any [% terms.bug %] you modify. Note that it's <strong>on</strong> 
    by default.</li>
  <li>[% terms.Bugs %] can now be filed with an initial state of 
    <kbd>ASSIGNED</kbd>, if you are in the <kbd>editbugs</kbd> group.</li>
  <li>By default, comment fields will zoom large when you are typing in them,
    and become small when you move out of them. You can disable this
    in your user preferences.</li>
  <li>You can hide obsolete attachments on [% terms.abug %] by clicking
    &quot;Hide Obsolete&quot; at the bottom of the attachment table.</li>
  <li>If [% terms.abug %] has flags set, and you move it to a different 
    product that has flags with the same name, the flags will be 
    preserved.</li>
  <li>You now can't request a flag to be set by somebody who can't set it
    ([% terms.Bugzilla %] will throw an error if you try).</li>
  <li>Many new headers have been added to outbound [% terms.Bugzilla %]
    [%+ terms.bug %] emails: <code>X-Bugzilla-Status</code>,
    <code>X-Bugzilla-Priority</code>, <code>X-Bugzilla-Assigned-To</code>,
    <code>X-Bugzilla-Target-Milestone</code>, and 
    <code>X-Bugzilla-Changed-Fields</code>, <code>X-Bugzilla-Who</code>.
    You can look at an email to get an idea of what they contain.</li>
  <li>In addition to the old <code>X-Bugzilla-Reason</code> email header
    which tells you why you got an email, if you got an email because
    you were watching somebody, there is now an 
    <code>X-Bugzilla-Watch-Reason</code> header that tells you who you
    were watching and what role they had.</li>
  <li>If you hover your mouse over a full URL (like 
    <code>http://bugs.mycompany.com/show_bug.cgi?id=1212</code>) that 
    links to [% terms.abug %], you will see the title of the 
    [%+ terms.bug %]. Of course, this only works for [% terms.bugs %] in your
    [%+ terms.Bugzilla %] installation.</li>
  <li>If your installation has user watching enabled, you will now see
    the users that you can remove from your watch-list as a multi-select
    box, much like the current CC list. (Previously it was just a text
    box.)</li>
  <li>When a user creates their own account in [% terms.Bugzilla %], the 
    account is now not actually created until they verify their email
    address by clicking on a link that is emailed to them.</li>
  <li>You can change [% terms.abug %]'s resolution without reopening it.</li>
  <li>When you view the dependency tree on [% terms.abug %], resolved 
    [%+ terms.bugs %] will be hidden by default. (In previous versions,
    resolved [% terms.bugs %] were shown by default.)</li>
  <li>When viewing [% terms.bug %] activity, fields that hold [% terms.bug %] 
    numbers (such as &quot;Blocks&quot;) will have the [% terms.bug %] numbers
    displayed as links to those [% terms.bugs %].</li>
  <li>When viewing the &quot;Keywords&quot; field in [% terms.abug %] list,
    it will be sorted alphabetically, so you can sanely sort a list on
    that field.</li>
  <li>In most places, the Version field is now sorted using a version-sort
    (so 1.10 is greater than 1.2) instead of an alphabetical sort.</li>
  <li>Options for flags will only appear if you can set them. So, for
    example, if you can't grant <kbd>+</kbd> on a flag, that option
    won't appear for you.</li>
  <li>You can limit the product-related output of <kbd>config.cgi</kbd>
    by specifying a <kbd>product=</kbd> URL argument, containing the name
    of a product. You can specify the argument more than once for multiple
    products.</li>
  <li>You can now search the boolean charts on whether or not a comment
    is private.</li>
</ul>

<h4>Enhancements For Administrators</h4>

<ul>
  <li>Administrators can now delete attachments, making them disappear
    entirely from [% terms.Bugzilla %].</li>
  <li><kbd>sanitycheck.cgi</kbd> can now only be accessed by users
    in the <kbd>editcomponents</kbd> group.</li>
  <li>The &quot;Field Values&quot; control panel can now only be accessed
    by users in the <kbd>admin</kbd> group. (Previously it was accessible
    to anybody in the <kbd>editcomponents</kbd> group.)</li>
  <li>There is a new parameter <kbd>announcehtml</kbd>, that will allow
    you to enter some HTML that will be displayed at the top of every
    page, as an announcement.</li>
  <li>The <kbd>loginnetmask</kbd> parameter now defaults to 0 for new
    installations, meaning that as long as somebody has the right
    login cookie, they can log in from any IP address. This makes
    life a lot easier for dial-up users or other users whose IP
    changes a lot. This could be done because the login cookie is now
    very random, and thus secure.</li>
  <li>Classifications now have sortkeys, so they can be sorted in an
    order that isn't alphabetical.</li>
  <li>Authentication now supports LDAP over SSL (LDAPS) or TLS (using
    the STARTLS command) in addition to plain LDAP.</li>
  <li>LDAP users can have their LDAP username be their email address,
    instead of having the LDAP <kbd>mail</kbd> attribute be their
    email address. You may wish to set the <kbd>emailsuffix</kbd>
    parameter if you do this.</li>
  <li>Administrators can now see what has changed in a user account,
    when using the &quot;Users&quot; control panel.</li>
  <li><code>REMIND</code> and <code>LATER</code> are no longer part
    of the default list of resolutions. Upgrading installations will
    not be affected--they will still have these resolutions.</li>
  <li><kbd>editbugs</kbd> is now the default for the <kbd>timetrackinggroup</kbd>
    parameter, meaning that time-tracking will be on by default in a new
    installation.</li>
</ul>

<h2><a name="v30_issues"></a>Outstanding Issues</h2>

<ul>
  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=69621">
    [%- terms.Bug %] 69621</a>: If you rename or remove a keyword that is
    in use on [% terms.bugs %], you will need to rebuild the "keyword cache"
    by running <a href="sanitycheck.cgi">sanitycheck.cgi</a> and choosing 
    the option to rebuild the cache when it asks. Otherwise keywords may 
    not show up properly in search results.</li>
  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=99215">
    [%- terms.Bug %] 99215</a>: Flags are not protected by "mid-air 
    collision" detection. Nor are any attachment changes.</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>
  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370370">
    [%- terms.Bug %] 370370</a>: mod_perl support is currently not
    working on Windows machines.</li>
  <li><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=361149">
    [%- terms.Bug %] 361149</a>: If you are using Perl 5.8.0, you may
    get a lot of warnings in your Apache error_log about "deprecated
    pseudo-hashes." These are harmless--they are a b[%# fool test %]ug in 
    Perl 5.8.0. Perl 5.8.1 and later do not have this problem.</li>
  <li>[% terms.Bugzilla %] 3.0rc1 allowed custom field column names in 
    the database to be mixed-case. [% terms.Bugzilla %] 3.0 only allows
    lowercase column names. It will fix any column names that you have
    made mixed-case, but if you have custom fields that previously were
    mixed-case in any Saved Search, you will have to re-create that Saved
    Search yourself.</li>
</ul>

<h2><a name="v30_security"></a>Security Updates in This Release</h2>

  For details, see the 
  <a href="http://www.bugzilla.org/security/2.22.4/">Security Advisory</a>.</p>

<h3>3.0.4</h3>

<p>[% terms.Bugzilla %] 3.0.4 contains three security fixes.
  For details, see the

  fixed in this release: one minor information leak, one hole only
  exploitable by an admin or using <code>email_in.pl</code>, and one in an
  uncommonly-used template. For details, see the 
  <a href="http://www.bugzilla.org/security/2.20.4/">Security Advisory</a>.</p>

<h2><a name="v30_upgrading"></a>How to Upgrade From An Older Version</h2>

<h3><a name="v30_upgrading_notes"></a>Notes For Upgraders</h3>

<ul>
  <li>If you upgrade by CVS, there are several .cvsignore files
    that are now in CVS instead of being locally created by 
    <kbd>checksetup.pl</kbd>. This means that you will have to
    delete those files when CVS tells you there's a conflict, and
    then run <kbd>cvs update</kbd> again.</li>
  <li>In this version of [% terms.Bugzilla %], the Summary field
    is now limited to 255 characters. When you upgrade, any Summary
    longer than that will be truncated, and the old summary will be
    preserved in a comment.</li>
  <li>If you have the <kbd>utf8</kbd> parameter turned on, at some
    point you will have to convert your database. <kbd>checksetup.pl</kbd>
    will tell you when this is, and it will give you certain instructions
    at that time, that you have to follow before you can complete
    the upgrade. Don't do the conversion yourself manually--follow
    the instructions of checksetup.pl.</li>
  <li>If you ever ran 2.23.3, 2.23.4, or 3.0rc1, you will have to run
    <kbd>./collectstats.pl --regenerate</kbd> at the command line, because
    the data for your Old Charts is corrupted. This can take several days,
    so you may only want to run it if you use Old Charts.</li>
  <li>You should also read the Outstanding Issues sections of
    <a href="#v30_previous">older release notes</a> if you are upgrading
    from a version lower than 2.22.</li>
</ul>

<h3>Steps For Upgrading</h3>

<p>Once you have read the notes above, see the 
  <a href="[% docs_urlbase FILTER html %]upgrade.html">Upgrading 
  documentation</a> for instructions on how to upgrade.</p>

<h2><a name="v30_code_changes"></a>Code Changes Which May Affect

</ul>

<h3><a name="v30_code_loc"></a><strong>Packagers:</strong> Location
    Variables Have Moved</h3>

<p>In previous versions of [% terms.Bugzilla %], <kbd>Bugzilla::Config</kbd>
  held all the paths for different things, such as the path to localconfig
  and the path to the <kbd>data/</kbd> directory.</p>

<p>Now, all of this data is stored in a subroutine,
  <kbd>Bugzilla::Constants::bz_locations</kbd>.</p>

<p>Also, note that for mod_perl, <kbd>bz_locations</kbd> must return
  <em>absolute</em> (not relative) paths. There is already code in that
  subroutine to help you with this.</p>

<h3><a name="v30_code_hooks"></a>Hooks!</h3>

<p>[% terms.Bugzilla %] now supports a code hook mechanism. See the 
  documentation for 
  <a href="[% docs_urlbase FILTER html %]api/Bugzilla/Hook.html">Bugzilla::Hook</a>
  for more details.</p>

<p>This gives [% terms.Bugzilla %] very advanced plugin support. You can
  hook templates, hook code, add new parameters, and use the XML-RPC
  interface. So we'd like to see some [% terms.Bugzilla %] plugins
  written! Let us know on the <a href="http://bugzilla.org/cgi-bin/mj_wwwusr?func=lists-long-full&amp;extra=developers">developers&#64;bugzilla.org</a>
  mailing list if you write a plugin.</p>

<p>If you need more hooks, please 
  <a href="http://www.bugzilla.org/developers/reporting_bugs.html">File a
  bug</a>!</p>

<h3><a name="v30_code_api"></a>API Documentation</h3>

<p>[% terms.Bugzilla %] now ships with all of its perldoc built
  as HTML. Go ahead and read the
  <a href="[% docs_urlbase FILTER html %]api/">API Documentation</a>
  for all of the [% terms.Bugzilla %] modules now! Even scripts like
  <kbd>checksetup.pl</kbd> have HTML documentation.</p>

<h3><a name="v30_code_globals"></a>Elimination of globals.pl</h3>

<p>The old file <kbd>globals.pl</kbd> has been eliminated.
  Its code is now in various modules. Each function went to the module
  that was appropriate for it.</p>

<p>Usually we filed [% terms.abug %] in 
  <a href="https://bugzilla.mozilla.org">bugzilla.mozilla.org</a> for
  each function we moved. You can search there for the old name of
  the function, and that should get you the information about what
  it's called now and where it lives.</p>

<h3><a name="v30_code_scope"></a>Cleaned Up Variable Scoping Issues</h3>

<p>In normal perl, you can have code like this:</p>
<pre>my $var = 0;
sub y { $var++ }</pre>

<p>However, under mod_perl that doesn't work. So variables are no
  longer &quot;shared&quot; with subroutines--instead all variables
  that a subroutine needs must be declared inside the subroutine itself.</p>

<h3><a name="v30_code_sql"></a>No More SendSQL</h3>

<p>The old <kbd>SendSQL</kbd> function and all of its companions are
  <strong>gone</strong>. Instead, we now use DBI for all database
  interaction.</p>

<p>For more information about how to use 
  <a href="http://search.cpan.org/perldoc?DBI">DBI</a> with 
  [% terms.Bugzilla %], see the 
  <a href="http://www.bugzilla.org/docs/developer.html#sql-sendreceive">Developer's
  Guide Section About DBI</a></p>

<h3><a name="v30_code_auth"></a>Auth Re-write</h3>

<p>The <kbd>Bugzilla::Auth</kbd> family of modules have been completely
  re-written. For details on how the new structure of authentication,
  read the 
  <a href="[% docs_urlbase FILTER html %]api/Bugzilla/Auth.html">Bugzilla::Auth
  API docs</a>.</p>

<p>It should be very easy to write new authentication plugins, now.</p>

<h3><a name="v30_code_obj"></a>Bugzilla::Object</h3>

<p>There is a new base class for most of our objects, 
  <a href="[% docs_urlbase FILTER html %]api/Bugzilla/Object.html">Bugzilla::Object</a>.
  It makes it really easy to create new objects based on things that are 
  in the database.</p>

<h3><a name="v30_code_req"></a>Bugzilla-&gt;request-cache</h3>

<p><kbd>Bugzilla.pm</kbd> used to cache things like the database
  connection in package-global variables (like <kbd>$_dbh</kbd>).
  That doesn't work in mod_perl, so instead now there's a hash
  that can be accessed through <code>Bugzilla-&gt;request_cache</code>
  to store things for the rest of the current page request.</p>

<p>You shouldn't access <code>Bugzilla-&gt;request_cache</code> directly,
  but you should use it inside of <kbd>Bugzilla.pm</kbd> if you modify
  that. The only time you should be accessing it directly is if you need
  to reset one of the caches. Hash keys are always named after the function
  that they cache, so to reset the template object, you'd do:
  <code>delete Bugzilla-&gt;request_cache-&gt;{template};</code>.</p>

<h3><a name="v30_code_other"></a>Other Changes</h3>

<ul>
  <li><code>checksetup.pl</code> has been completely re-written, and most
    of its code moved into modules in the <kbd>Bugzilla::Install</kbd>
    namespace. See the
    <a href="[% docs_urlbase FILTER html %]api/checksetup.html">checksetup
    documentation</a> and <a href="https://bugzilla.mozilla.org/showdependencytree.cgi?id=277502&amp;hide_resolved=0">[% terms.Bugzilla %]
   [%+ terms.bug %] 277502</a> for details.</li>
  <li>Instead of <kbd>UserInGroup()</kbd>, all of [% terms.Bugzilla %] now 
    uses <kbd>Bugzilla-&gt;user-&gt;in_group</kbd></li>
  <li>mod_perl doesn't like dependency loops in modules, so we now have
    a test for that detects dependency loops in modules when you run
   <kbd>runtests.pl</kbd>.</li>
  <li><kbd>globals.pl</kbd> used to modify the environment variables,
    like <kbd>PATH</kbd>. That now happens in <kbd>Bugzilla.pm</kbd>.</li>
  <li>Templates can now link to the documentation more easily.
    See the <kbd>global/code-error.html.tmpl</kbd> and
    <kbd>global/user-error.html.tmpl</kbd> templates for examples.
    (Search for &quot;docslinks.&quot;)</li>
  <li>Parameters are accessed through <kbd>Bugzilla-&gt;params</kbd>
    instead of using the <kbd>Param()</kbd> function, now.</li>
  <li>The variables from the <kbd>localconfig</kbd> file are accessed
    through the <code>Bugzilla-&gt;localconfig</code> hash instead of through
    <kbd>Bugzilla::Config</kbd>.</li>
  <li><kbd>Bugzilla::BugMail::MessageToMTA()</kbd> has moved into its
    own module, along with other mail-handling code, called
    <kbd>Bugzilla::Mailer</kbd></li>
  <li>The <kbd>CheckCanChangeField()</kbd> subroutine in 
    <kbd>process_bug.cgi</kbd> has been moved to <kbd>Bugzilla::Bug</kbd>,
    and is now a method of [% terms.abug %] object.</li>
  <li>The code that used to be in the <kbd>global/banner.html.tmpl</kbd>
    template is now in <kbd>global/header.html.tmpl</kbd>. The banner
    still exists, but the file is empty.</li>
</ul>
