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

<p>Welcome to Bugzilla 3.0! It's been over eight years since
  we released Bugzilla 2.0, and everything has changed since
  then. Even just since our previous release, 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 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="https://github.com/bugzilla/bugzilla.github.io/compare/3.0">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">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">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">Bug 433851</a>)</li>
  <li>If you were running mod_perl, 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">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">Bug 441541</a>)</li>
  <li><a href="https://www.bugzilla.org/docs/3.0/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">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>Bugzilla administrators were not being correctly notified
    about new releases.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=414726">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">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">Bug 384009</a>)</li>

  <li>Better threading of bugmail in some email clients.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=376453">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">Bug 92274</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=377025">Bug 377025</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=412943">Bug 412943</a>,
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=413672">Bug 413672</a>, and
     <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=431721">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">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">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">Bug 405946</a>)

  </li><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">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">Bug 414430</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>3.0.3</h3>

<ul>
  <li>mod_perl no longer compiles 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">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">Bug 362436</a>)</li>

  <li>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">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">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">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">Bug 400160</a>)</li>

  <li>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">Bug 408766</a>)</li>
</ul>

<h3>3.0.2</h3>

<ul>
  <li>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">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 a bug.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370739">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">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">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 Bugzilla.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365756">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
    Bugzilla under mod_perl.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=370398">Bug 370398</a>)</li>
  <li>If moving a bug between products would remove groups
    from the bug, you are now warned.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=303183">Bug 303183</a>)</li>
  <li>On IIS, whenever 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">Bug 390148</a>)</li>
  <li>If you used <kbd>email_in.pl</kbd> to edit a bug that was
    protected by groups, all of the groups would be cleared.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=385453">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">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">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">Bug 380709</a>)</li>
  <li>Logging into Bugzilla from the home page works again
    with IIS5. 
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=364008">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">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">Bug 381737</a>)</li>
  <li>The "Bug-Writing Guidelines" page has been shortened
    and re-written.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=378590">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">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">Bug 384497</a>)</li>
  <li>If you are a "global watcher" (you get all mails from every bug), you can now see that in your Email Preferences.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=365302">Bug 365302</a>)</li>
  <li>The Status and Resolution of bugs are now correctly
    localized in CSV search results.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=389517">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">Bug 387860</a>)</li>
  <li>Editing the "languages" parameter using <kbd>editparams.cgi</kbd> would
    sometimes fail, causing Bugzilla to throw an error.
    (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=335354">Bug 335354</a>)</li>

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

<p>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 "Field Values" control panel.</p>

<p>Don't add too many custom fields! It can make 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 Bugzilla, only then should you
  start your custom fields.</p>

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

<p>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 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, 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 "share" their saved searches
  with a certain group. That group will then be able to 
  "subscribe" to those searches, and have them appear
  in their footer.</p>

<p>If the sharer can "bless" 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 "Preferences" screen.</p>

<h3><a name="v30_feat_afn"></a>Attachments and Flags on New Bugs</h3>

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

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

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

<p>You can now customize the list of resolutions available
  in 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 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 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 "Format for Printing" page for bugs.</li>
  <li>The layout of <kbd>show_bug.cgi</kbd> (the 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>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="https://www.bugzilla.org/docs/3.0/html/api/">Bugzilla 
  API Docs</a>, in the various <kbd>Bugzilla::WebService</kbd> modules.</p>

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

<p>Bugzilla can have multiple "skins" installed,
  and users can pick between them. To write a skin, you just have to
  write several CSS files. See the <a href="https://www.bugzilla.org/docs/3.0/html/cust-skins.html">Custom
  Skins Documentation</a> for more details.</p>

<p>We currently don't have any alternate skins shipping withBugzilla. 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 a bug, 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
  Bugzilla sends.</p>

<h3><a name="v30_feat_df"></a>No More Double-Filed Bugs</h3>

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

<p>Now, if you try to submit a bug twice from the same screen 
  (by going back or by refreshing the page), Bugzilla will warn 
  you about what you're doing, before it actually submits the duplicate
  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 bugs in a component.</p>

<h3><a name="v30_feat_emi"></a>File/Modify Bugs By Email</h3>

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

<p>For more details see the <a href="https://www.bugzilla.org/docs/3.0/html/api/email_in.html">documentation
  for email_in.pl</a>.</p>

<h3><a name="v30_feat_gw"></a>Users Who Get All Bug 
  Notifications</h3>

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

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

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

<p>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.) 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 Bugzilla
  available to download.</p>

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

<p>If your 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 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 Bugzilla to their search bar.
  This uses the 
  <a href="https://landfill.bugzilla.org/bugzilla-3.0-branch/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 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 bug you modify. Note that it's <strong>on</strong> 
    by default.</li>
  <li>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 a bug by clicking
    "Hide Obsolete" at the bottom of the attachment table.</li>
  <li>If a bug 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
    (Bugzilla will throw an error if you try).</li>
  <li>Many new headers have been added to outbound Bugzilla
    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 a bug, you will see the title of the 
    bug. Of course, this only works for bugs in your
    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 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 a bug's resolution without reopening it.</li>
  <li>When you view the dependency tree on a bug, resolved 
    bugs will be hidden by default. (In previous versions,
    resolved bugs were shown by default.)</li>
  <li>When viewing bug activity, fields that hold bug 
    numbers (such as "Blocks") will have the bug numbers
    displayed as links to those bugs.</li>
  <li>When viewing the "Keywords" field in a bug 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 Bugzilla.</li>
  <li><kbd>sanitycheck.cgi</kbd> can now only be accessed by users
    in the <kbd>editcomponents</kbd> group.</li>
  <li>The "Field Values" 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 "Users" 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">Bug 69621</a>: If you rename or remove a keyword that is
    in use on bugs, you will need to rebuild the "keyword cache"
    by running <a href="https://landfill.bugzilla.org/bugzilla-3.0-branch/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">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">Bug 89822</a>: When changing multiple 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">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">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">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 bug in 
    Perl 5.8.0. Perl 5.8.1 and later do not have this problem.</li>
  <li>Bugzilla 3.0rc1 allowed custom field column names in 
    the database to be mixed-case. 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>

  exploitable by an admin or using <code>email_in.pl</code>, and one in an
  uncommonly-used template. For details, see the 
  <a href="https://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>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 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="https://www.bugzilla.org/docs/3.0/html/upgrade.html">Upgrading 
  documentation</a> for instructions on how to upgrade.</p>

  <li><a href="#v30_code_other">Other Changes</a></li>
</ul>

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

<p>In previous versions of 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>Bugzilla now supports a code hook mechanism. See the 
  documentation for 
  <a href="https://www.bugzilla.org/docs/3.0/html/api/Bugzilla/Hook.html">Bugzilla::Hook</a>
  for more details.</p>

<p>This gives 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 Bugzilla plugins
  written! Let us know on the <a href="https://lists.bugzilla.org/listinfo/developers">developers@bugzilla.org</a>
  mailing list if you write a plugin.</p>

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

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

<p>Bugzilla now ships with all of its perldoc built
  as HTML. Go ahead and read the
  <a href="https://www.bugzilla.org/docs/3.0/html/api/">API Documentation</a>
  for all of the 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 a bug 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 "shared" 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 Bugzilla, see the 
  <a href="https://www.bugzilla.org/contributing/developer#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="https://www.bugzilla.org/docs/3.0/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="https://www.bugzilla.org/docs/3.0/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="https://www.bugzilla.org/docs/3.0/html/api/checksetup.html">checksetup
    documentation</a> and <a href="https://bugzilla.mozilla.org/showdependencytree.cgi?id=277502&amp;hide_resolved=0">Bugzilla
   bug 277502</a> for details.</li>
  <li>Instead of <kbd>UserInGroup()</kbd>, all of 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 "docslinks.")</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 a bug 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>
