-2.18 has not been released yet - these are prerelease notes.
-
-Insert nice little intro for version 2.18 here.
-
-**************************
-*** ABOUT THIS VERSION ***
-**************************
-
-This is a development snapshot release of Bugzilla. As such the remainder of
-these release notes have NOT been updated (we usually do this just prior to a
-stable release). For information about a development snapshot release, the
-best source of information is on our website (http://www.bugzilla.org/) in
-the Status Updates area. Development snapshot releases are NOT recommended
-for production use unless you have an expert Perl programmer on hand willing
-to combat any difficulties you run into, since there is no guarantee of
-stability during a development cycle. You have been warned.
-
-
-Bug numbers referenced in this document are all on
-bugzilla.mozilla.org unless otherwise specified.
-
-*** Recommended Practice For The Upgrade ***
-
-As always, please ensure you have run checksetup.pl after
-replacing the files in your installation.
-
-It is recommended that you view the sanity check page
-(sanitycheck.cgi) both before the upgrade and after running
-checksetup.pl after the upgrade, to see if there are any
-problems with your installation.
-
-It is also recommended that if you can, you immediately fix
-any problems you find. Be aware that if the sanity check page
-contains more errors after an upgrade, it doesn't necessarily
-mean there are more errors in your database, as additional
-tests are added to the sanity check over time, and it is likely
-those errors weren't being checked for in the old version.
-
-Failure to do this may mean that bugzilla will not
-work correctly.
-
-Administrators must make sure that certain files are
-inaccessible or confidential information might become
-available to enterprising individuals. This includes the
-localconfig file and the entire data directory. Please
-see the Bugzilla Guide for more information.
-
-*** Dependency Requirements ***
-
-MySQL v3.23.41
-Perl v5.6.0
-CGI v2.88
-DBI v1.32
-DBD::mysql v2.1010
-AppConfig v1.52
-Template Toolkit v2.08
-Text::Wrap v2001.0131
-File::Spec v0.82
-Date::Format v2.21
-Data::Dumper, File::Temp, CGI::Carp (any)
-GD v1.20 (optional)
-GD::Text::Align (any, optional)
-GD::Graph (any, optional)
-Chart::Base v0.99 (optional)
-XML::Parser (any, optional)
-
-*** Deprecated Features ***
-
-- (already happened - move this in 2.18 notes) This is
- possibly the last stable release that will work with
- MySQL version 3.22. Soon Bugzilla will require at least
- version 3.23.x. The exact minimum version number required
- has not yet been decided.
- (bug 87958)
-
-- (already happened - move this in 2.18 notes) This is
- possibly the last stable release to support the
- shadow database. The replacement (using MySQL's built in
- replication) is not present in 2.16, but we expect that
- very few sites use this feature, so we are not planning a
- transition period. If this would cause a problem for you,
- please comment on the below bug.
- (bug 124589)
-
-- Placing comments in localconfig is deprecated. If you have done
- this, they will likely get nuked with future version of
- Bugzilla, as checksetup.pl will likely automatically rewrite localconfig
- to automatically get the latest comments.
- (bug 147776)
-
-*** Outstanding Issues Of Note ***
-
-These issues may have been fixed in later stable or development
-versions of Bugzilla. If you are interested in tracking these
-bugs, please see the bug report numbers listed to find out the
-status of the fix for these bugs, or to obtain a patch that can
-fix the problem on your installation.
-
-- Renaming or removing keywords that are in use will not update
- the "keyword cache" on bugs, and queries on keywords may not work
- properly, until you rebuild the cache on the sanity check page
- (sanitycheck.cgi). The changer will receive a warning to do
- this when altering the keyword.
- (bug 69621)
-
-- Email notifications will not work out of the box if you are
- using Postfix, Exim or possibly other non-SendMail mail
- transfer agents, as Bugzilla sends mail by default in
- "deferred" mode using the "-ODeliveryMode=deferred" command
- line option, which needs to be supported by the sendmail
- program. To fix this, you can turn on the "sendmailnow"
- parameter on the Edit Parameters page (editparams.cgi).
- (bug 37765)
-
-- Users behind rotating transparent proxies or otherwise having
- an IP that changes each URL fetch will find they need to log in
- regularly.
- (bug 20122)
-
-- If you search on any CC or added comments, as well as at least
- one other of CC, added comments, assignee, reporter, etc, then
- the search can be very slow. This is because of limitations of
- the MySQL optimiser.
- (bug 96101)
-
-- It is recommended you use the high speed XS Stash of the Template
- Toolkit, in order to achieve best performance. However, there are
- known problems with XS Stash and Perl 5.005_02 and lower. If you
- wish to use these older versions of Perl, please use the regular
- stash. You are asked which stash you want to use at Template Toolkit
- installation time.
- (bug 140674)
-
-- Querying on CC takes too long on big databases.
- (bug 127200)
-
-- Attachment changes have no midair collision detection, unlike bug changes.
- (bug 99215)
-
-- The email preferences option "Priority, status, severity, and/or milestone
- changes" does not actually report status changes. You can however use the
- option "The bug is resolved or verified" to achieve part of this.
- (bug 130821)

- using Perl math that is not exact beyond 2^48. This results in the new
- group being defined with a "bit" that has several bits set. As users are
- given access to the new group, those users will also gain access to
- spurious lower group privileges. Also, group bits were not always reused
- when groups were deleted.

+*** The Bugzilla 2.18 Release Notes ***
+***************************************
+
+Introduction
+************
+
+This document contains the release notes for Bugzilla 2.18. In this document
+recently added, changed, and removed features of Bugzilla are described.
+
+The 2.18 release is the first in a new stable series, containing the results
+of over two years of hard and dedicated work by volunteers all over the world
+under the lead of Dave Miller.
+
+This is a preliminary document detailing how we expect things to be in the
+final 2.18 release. The contents of this document are subject to change up
+until the final release. Please file bugs in Bugzilla for any additions or
+corrections needed in this document.
-- The email interface had another insecure single parameter system call. This
- could potentially allow arbitrary shell commands to be run. This file is
- not supported at this time, but as long as we knew about the problem, we
- couldn't overlook it.
- (bug 163024)
-*** Bug fixes of note ***
-
-- The email interface was broken. This was a 2.14.3 regression. This file
- is not supported at this time, but as long as we knew about the problem, we
- couldn't overlook it.
- (bug 160631)
+Dependency Requirements
+-----------------------
+
+Minimum software requirements:
+
+ MySQL v3.23.41 (changed from 2.16)
+ Perl v5.6.0 (changed from 2.16)
-***********************************************
-*** USERS UPGRADING FROM 2.14.5 OR EARLIER ***
-***********************************************
-
-*** SECURITY ISSUES RESOLVED ***
-
-- The bug reporter could set the priority even when
- 'letsubmitterchoosepriority' was off.
- (bug 63018)
-
-- Most CGIs are now templatised. This helps to make it
- easier to remember to HTML filter values and easier to spot
- when they are not, preventing cross site scripting attacks.
- (bug 86168)
-
-- Most CGIs now run in taint mode. This helps to prevent
- failure to validate errors.
- (bug 108982)
-
-*** IMPORTANT CHANGES ***
-
-- 2.16 introduces "templatisation", a new feature that allows
- administrators to easily customise the HTML output (the "look and feel")
- of Bugzilla without altering Perl code. Bugzilla uses the
- "Template Toolkit" for this. Please see the "Template Customisation"
- section of the Bugzilla Guide for more details.
-
- Administrators who ran the 2.15 development version and customised
- templates should check the templates are still valid, as file names
- and file paths have changed.
-
- Most output is now templatised. This process will be complete next
- milestone.
-
- For speed, compiled templates are cached on disk. If you modify the
- templates, the toolkit will normally detect the changes, and recompile the
- changed templates.
-
- Adding new directories anywhere inside the template directory may cause
- permission errors if you don't have a webservergroup specified in
- localconfig. If you see these, rerun checksetup.pl as root. If you do not
- have root access, or cannot get someone who does to do this for you, you can
- rename the data/template directory to data/template.old (or any other name
- Bugzilla doesn't use). Then rerun checksetup.pl to regenerate the compiled
- templates.
- (bug 86168, 97832)
-
-- Administrators can now configure maximum attachment sizes. These
- should remain below the maximum size for your MySQL server, or you
- will get obscure MySQL errors if you attach a bigger attachment.
-
- To find out the current size attachment that MySQL can accept, type
- the command 'mysqladmin variables' and find out the value of the
- 'max_allowed_packet' varible in bytes.
-
- To change the maximum size that MySQL can accept you can alter this
- variable in your 'my.cnf' file.
- (bug 91664)
-
-- Perl 5.004 is no longer supported because the Template Toolkit
- requires 5.005.
- (bug 97721)
-
-- New module requirements: Text::Wrap, Template [requires AppConfig],
- File::Spec.
- (bugs 97784, 84338, 103778)
-
-- The index page is now a CGI instead of an HTML page. You should remove
- any existing index.html file and make sure your web server allows index.cgi
- to be the default page in a directory. If you are not able to do that you
- can instead set index_html in the 'localconfig' file to 1 and checksetup.pl
- will create a redirect page for you.
- (bug 80183)
-
-- It is now recommended that administrators run "processmail rescanall"
- after upgrading to 2.16 or beyond.
-
- This will send out notification emails for changes that were
- made but not emailed, due to Bugzilla bugs. All known
- causes of this have been fixed in this version (bug 104589 and 99519).
-
- It is also recommended that this be run nightly to avoid
- lengthy delays in future if this problem reoccurs.
- (bug 106377)
-
-- In parallel with templatisation, a lot of changes have been made to the HTML
- output of the Bugzilla CGIs. This could break code that attempts to parse
- such code. For example, this breaks mozbot.
- (no bug number)
-
-- The "HTML template" parameters (headerhtml, bodyhtml, footerhtml,
- errorhtml, bannerhtml, blurbhtml, mostfreqhtml, entryheaderhtml) have now
- been moved to Template Toolkit templates. If you have modified these
- parameters you will need to make corresponding changes to the corresponding
- templates. Your old parameter values will be moved to a file called
- old-params.txt by checksetup.pl.
-
- The old parameters correspond to files in template/en/default as follows:
-
- headerhtml: global/header.html.tmpl
- footerhtml: global/footer.html.tmpl
- bannerhtml: global/banner.html.tmpl
- blurbhtml: global/banner.html.tmpl
- mostfreqhtml: reports/duplicates*.html.tmpl
- entryheaderhtml: bug/create/user-message.html.tmpl
-
- (bug 140437)
-

-
-- The query page has been redesigned for better user friendliness.
- (bug 98707)
-- Users can now change their email account.
- (bug 23067)
-- "Dependent Bug Changed" notification emails now contain the
- dependent bug's summary and URL.
- (bug 28736, 113383)
-- Bugs with severity "critical", "blocker", and "enhancement" are
- visually differentiated on bug lists for browsers with sufficient
- CSS support.
- (bug 28884)
-- Bugzilla now has a sidebar for the Mozilla browser.
- (bug 37339)

- email.
- (bug 66651)
-- Comments now have numbers and can be referenced with
- autohyperlinkifying similar to bugs.

- (bugs 84338, 75176)
-- syncshadowdb now supports a configurable temp file location,
- and properly shuts down Bugzilla while running.
- (bug 75840)
-- Dependency tree now lets you exclude resolved bugs and bugs
- below a specified depth.
- (bugs 83058)
-- The "strictvaluechecks" parameter has gone away. These checks
- are now always done.
- (bug 119715)
-- The midair collision page now shows all changes since the bug
- page was loaded, not just the last one.
- (bug 108312)
-- Added support for making dependency graphs with 'dot', which
- is better at creating complex graphs than 'webdot'.
- (bug 120537)
-
-*** Bug fixes of note ***
-
-- Bugzilla scripts are now usually not terminated when the browser
- window they are running in is closed. This caused hard to
- reproduce bugs.
- (bug 104589)
-- On browsers that "reflow" the page, large component / milestone /
- version fields were extremely slow to reflow when you altered
- the product field.
- (bug 96534)
-- The selection in the component / milestone / version fields is
- no longer lost when you change the selection in the product
- field or use the back/forward buttons in your browser to return
- to the page.
- (bug 97966)
-- You could not reverse dependencies in one step.
- (bug 82143)
-- Mass reassignment of non-open bugs will no longer reopen them.
- (bug 30731)
-- Attempting to bulk change no bugs will now give a user-friendly
- error message.
- (bug 90333)
-- If you make a change to a bug where you only add yourself to CC,
- email notifications are now properly sent out for MySQL 3.23.
- (bug 99519)
-- Bug entry now properly validates the data it has been sent.
- (bug 107743)
-- Midair collision checks will now properly work in all situations
- where dependencies have changed.
- (bug 73502)
-- Browsers can no longer corrupt the params file if they use the "wrong"
- end-of-line markers.
- (bug 92500)
-- The MySQL port defined in localconfig is now properly honoured.
- (bug 98368)
-- Apostrophes in component/milestone/version names no longer cause
- a problem on the query page.
- (bug 30689/42810)
-- File attachment comments will now wrap.
- (bug 52060)
-- Saved queries are no longer mangled if you need to log in again,
- for example if you had cookies off.
- (bug 38835)
-- Bug counts (on reports.cgi) were very slow if you had to
- count a lot of bugs.
- (bug 63249)
-- 2.14 introduced options to let people see a bug when their name
- is on it but who aren't in the groups the bug is restricted
- to. These only allowed the people to view the bugs directly,
- and not see them on buglists and receive email about them.
- (bugs 95024, 97469)
-- A new 'cookiepath' parameter on editparams.cgi allows multiple
- Bugzilla installations to exist on one host without problems.
- (bug 19910)
-- whineatnews.pl now respects the 'sendmailnow' parameter.
- (bug 52782)

-- It was possible for a user to bypass the IP check by
- setting up a fake reverse DNS, if the Bugzilla web server
- was configured to do reverse DNS lookups. Apache is not

-
-*** SECURITY ISSUES RESOLVED ***
-
-- If LDAP Authentication was being used, Bugzilla would allow
- you to log in as anyone if you left the password blank.
- (bug 54901)
-
-- It was possible to add comments or file a bug as someone else
- by editing the HTML on the appropriate submission page before
- submitting the form. User identity is checked now, and the
- form values suggesting the user are now ignored.
- (bug 108385, 108516)
-
-- The Product popup menu on the show_bug form listed all
- products, even if the user didn't have access to all of them.
- It now only shows products the user has access to (and the
- product the bug is in, if the user is viewing it because of
- some other override).
- (bug 102141)
-
-- If a user had any blessgroupset privileges (the ability to
- change only specific privileges for other users), it was
- possible to change your own groupset (privileges) by
- altering the page HTML before submitting on editusers.cgi.

-*** SECURITY ISSUES RESOLVED ***
-
-- Multiple instances of unauthorised access to confidential
- bugs has been fixed.
- (bug 39524, 39526, 39527, 39531, 39533, 70189, 82781)
-
-- Multiple instances of untrusted parameters not being
- checked/escaped was fixed. These included definite security
- holes.
- (bug 38854, 38855, 38859, 39536, 87701, 95235)
-
-- After logging in passwords no longer appear in the URL.
- (bug 15980)
-
-- Procedures to prevent unauthorised access to confidential
- files are now simpler. In particular the shadow directory
- no longer exists and the data/comments file no longer needs
- to be directly accessible, so the entire data directory can
- be blocked. However, no changes are required here if you
- have a properly secured 2.12 installation as no new files
- must be protected.
- (bug 71552, 73191)
-
-- If they do not already exist, checksetup.pl will attempt to
- write Apache .htaccess files by default, to prevent
- unauthorised access to confidential files. You can turn this
- off in the localconfig file.
- (bug 76154)
-
-- Sanity check can now only be run by people in the 'editbugs'
- group. Although it would be better to have a separate
- group, this is not possible until the limitation on the
- number of groups allowed has been removed.
- (bug 54556)
-
-- The password is no longer stored in plaintext form. It will
- be eradicated next time you run checksetup.pl. A user must
- now change their password via a password change request that
- gets validated at their e-mail account, rather than have it
- mailed to them.
- (bug 74032)
-
-- When you are using product groups and you move a bug between
- products (single or mass change), the bug will no longer be
- restricted to the old product's group (if it was) and will
- be restricted to the new product's group.
- (bug 66235)
-
-- There are now options on a bug to choose whether the
- reporter, and CCs can access a bug even if they aren't in
- groups the bug it is restricted to.
- (bug 39816)
-
-- You can no longer mark a bug as a duplicate of a bug you
- can't see, and if you mark a bug a duplicate of a bug
- the reporter cannot see you will be given options as to
- what to do regarding adding the reporter of the resolved
- bug to the CC of the open bug.
- (bug 96085)
-
-*** IMPORTANT CHANGES ***
-
-- Bugzilla 2.14 no longer supports old email tech. Upon
- upgrading, all users will be moved over to new email tech.
- This should speed up upgrading for installations with
- a large number of bugs.
- (bug 71552)
-
-- There is new functionality for people to see why they are
- receiving notification mails.
-
- Previously, some people filtered old email tech
- notifications depending on whether they were in the To or the
- CC header, in order to get a limited way of determining why
- they were receiving the notification for filtering purposes.
-
- Existing installations will need to make changes to support
- this feature. The receive reasons can be added to the
- notifications as a header and/or in the body. To add these
- you will need to modify your newchangedmail parameter on
- editparams.cgi, either by resetting it or appropriately
- modifying it. The header value is specified by
- %reasonsheader% and the body by %reasonsbody%. For example,
- the new default parameter is:
-
- --------------------------------------------------
- From: bugzilla-daemon
- To: %to%
- Subject: [Bug %bugid%] %neworchanged%%summary%
- X-Bugzilla-Reason: %reasonsheader%
-
- %urlbase%show_bug.cgi?id=%bugid%
-
- %diffs%
-
-
-
- %reasonsbody%
- --------------------------------------------------
-
- (bug 26194)
-
-- Very long fields (especially multi-valued fields like keywords,
- CCs, dependencies) on bug activity and notifications previously
- could get truncated, resulting in useless notifications and data
- loss on bug activity. Now the multi-valued fields only show
- changes, and very big changes are split into multiple lines.
- Where data loss has already occurred on bug activity, it is
- indicated using question marks.
- (bug 55161, 92266)
-
-- Previously, when a product's voting preferences changed all
- votes were removed from all the bugs in the product. Also,
- when a bug was moved to another product, all of its votes
- were removed. This no longer occurs.
-
- Instead, if the action would leave one or more bugs with
- greater than the maximum number of votes per person per bug,
- the number of votes will be reduced to the maximum. The
- person will still be notified of this as before.
-
- If the action would leave a user with more votes in a product
- than is allowed, the limit will be breached so as to not lose
- votes. However the user will not be able to update their
- votes except to fix this situation. No further action is taken
- in this version to make sure that the user does this.
- (bug 28882, 92593)
-
-*** Other changes of note ***
-
-- Groups can now be marked inactive, so you can't add a new
- restriction on that group to a bug, while leaving bugs that
- were previously restricted on that group alone.
- (bug 75482)
-- backdoor.cgi has been removed from the installation. It was
- old code that was Netscape-specific and its name was scaring
- people.
- (bug 87983)
-- You can now add or remove from CC on the bulk change page.
- (bug 12819)
-- New users created by administrators are now automatically
- inserted into groups according to the group's regular
- expression. Administrators must edit the user in a second
- step to override these choices. Previously the
- administrator specified these explicitly which could lead
- to incorrect settings.
- (bug 45164)
-- The userregexp of system groups can now be edited without
- resorting to direct database access.
- (bug 65290)
-
-*** Bug fixes of note ***
-
-- The bug list page was sometimes bringing up a not logged in
- footer when the user was logged in and the installation was
- using a shadow database.
- (bug 47914)
-- You can now view the bug summary in your browser title for
- a group-restricted bug if you have proper permissions.
- (bug 71767)
-- Quick search for search terms did not work in IE5.
- This has been worked around.
- (bug 77699)
-- Quick search for search terms crashed NN4.76/4.77 for Unix.
- This has been worked around.
- (bug 83619)
-- Queries on bugs you have commented on using the "added
- comment" feature should be a lot faster and not time out
- on large installations due to the addition of an index.
- (bug 57350)
-- You can now alter group settings on bulk change for groups
- that aren't on for all bugs or off for all bugs.
- (bug 84714)
-- New bug notifications now include the CC and QA fields.
- (bug 28458)
-- Bugzilla is now more Windows friendly, although it is still
- not an official platform.
- (bug 88179, 29064)
-- Passwords are now encrypted using Perl's encrypt function.
- This makes Bugzilla more portable to more operating systems.
- (bug 77473)
-- Bugzilla didn't properly shut down when told to - some
- queries could still be sent to the database.
- (bug 95082)
+What's New?
+***********
+
+Generic Reporting
+-----------------
+
+Bugzilla has a new mechanism for generating reports of the current state of
+the bug database. It has two related parts: a table-based view, and several
+graphical views.
+
+The table-based view allows you to specify an x, y and z (multiple tables of
+data) axis to plot, and then restrict the bugs plotted using the standard
+query form. You can view the resulting data as an HTML or CSV export (e.g.:
+for importing into a spreadsheet).
+
+There are also bar, line and pie charts, which are defined in a very similar
+way. These views may be more appropriate for particular data types, and are
+suitable for saving and then putting into presentations or web pages.
+
+
+Request System
+---------------
+
+The Request System (RS) is a set of enhancements that adds powerful flag
+(superset of the old attachment status) features to the bugs.
+
+RS allows for four states: off, granted, denied, and (optionally) requested,
+where "granted" is the equivalent of "on". These additions mean it is no
+longer necessary to define a status to negate another status (e.g.
+"needs-work" to negate "has-review") because negation is built into each
+status via the status' "denied" state. Bug statuses: Previously only
+attachments could have these kinds of statuses. RS enables them for bugs as
+well. This feature can be used to request and grant/deny certain properties
+for a bug, such as inclusion for a specific milestone or approval for checkin.
+This way, Bugzilla supports the natural decision-making process in your
+organization.
+
+- Requests: Flags can now optionally be made requestable, which means users
+ can ask other users to set them. When a user requests a flag, Bugzilla
+ emails the requestee and adds the request to a browsable queue so both the
+ requester and the requestee can keep track of its status. Once the
+ requestee fulfills the request by setting the flag to either granted or
+ denied, Bugzilla emails the requestee and removes the request from the
+ queue. This feature supports workflow like the mozilla.org code review
+ and milestone approval processes, whereby code is peer reviewed before
+ being committed and patches get approved by product release managers for
+ inclusion in specific product releases.
+
+- Product/component specificity: Previously flags were product-specific, and
+ if you wanted the same flag for multiple products you had to define
+ multiple flags with the same name. Flags are now
+ product/component-specific, and a single flag can be enabled or disabled
+ for multiple product/component combinations via inclusions and exclusions
+ lists. Flags are enabled for all combinations on their inclusions list
+ except those that appear on their exclusions list.
+
+
+Enterprise Group Support
+------------------------
+
+Bugzilla is no longer limited to 55 access control groups. Administrators can
+define an arbitrary number of access groups composed of individual users or
+other groups. The groups can be configured via the web interface to achieve a
+wide variety of access control policies. See the documentation section on
+'Groups And Group Controls' for details.
+
+
+User Wildcard Matching
+----------------------
+
+Sites can now enable the use of wildcards and substrings in bug entry and
+editing forms. If the user enters an incomplete username, he'll get a list of
+users that matched the given username.
+
+
+Support for "Insiders"
+----------------------
+
+If the 'insidergroup' parameter is defined, a specific group of users can be
+designated insiders who can designate comments and attachments as private to
+other insiders. These comments and attachments will be invisible to other
+users who are not members of the insiders group even if the bugs to which they
+apply are visible. Other insiders will see the comments and attachments with a
+visual tinting indicating that they are private.
+
+
+Time Tracking
+-------------
+
+Controls for tracking time spent fixing bugs are included in the bug form for
+members of the group specified by the 'timetrackinggroup' parameter. Any time
+comments are added to the bug, members of the time tracking group can add an
+amount of time they spent, and it's figured into the total and displayed at
+the top of the bug. Shown in the bug are your original estimate, the amount of
+time spent so far, the revised estimate of how much time is remaining, and
+your gain/loss on the original estimate.
+
+
+Authentication module/LDAP improvements
+---------------------------------------
+
+Bugzilla's authentication mechanisms have been modularized, making pluggable
+authentication schemes for Bugzilla a reality. Both the existing database and
+LDAP systems were ported as part of modularization process. Additionally, the
+CGI portion of the backend was redesigned to allow for authentication from
+other sources, including (theoretically) email, which will help Bug 94850.
+
+As part of this conversion, LDAP logins now use Perl's standard Net::LDAP
+module, which has no external library dependencies.
+
+
+Improved localization support
+-----------------------------
+
+Bugzilla administrators can now configure which languages are supported by
+their installations and automatically serve correct, localized content to
+users based on the HTTP 'Accept-Language' header sent from users' browsers.
+
+There are currently localized templates available for: Arabic, Belarusian,
+Chinese, French, German, Italian, Korean, Portuguese (Brazil) Spanish (Spain
+or Mexico) and Russian. These localized template packs are third-party
+contributions, may only be available for specific versions, and may not be
+supported in the future. (http://www.bugzilla.org/download/#localizations)
+
+
+Patch Viewer
+------------
+
+Viewing and reviewing patches in Bugzilla is often difficult due to lack of
+context, improper format and the inherent readability issues that raw patches
+present. Patch Viewer is an enhancement to Bugzilla designed to fix that by
+offering increased context, linking to sections, and integrating with Bonsai,
+LXR and CVS.
+
+
+Comment Reply Links
+-------------------
+
+In Edit Bug, each bug comment now includes a convenient (reply) link that
+quotes the comment text into the textarea. This feature is only enabled in
+Javascript-capable browsers, but causes no inconvenience to other user agents.
+
+
+Full-Text Search
+----------------
+
+It is now possible to query the Bugzilla database using full-text searching,
+which spans comments and summaries, and which searches for substrings and stem
+variations of the search term. Basically, it's like using Google.
+
+
+Email Address Munging
+---------------------
+
+The fact that raw email addresses are displayed in Bugzilla makes it trivial
+for bots that spamharvest to spider through Bugzilla, in particular, through
+Bugzilla's buglists. This change adds HTML obfuscation of email addresses as
+they appear in the Bugzilla web pages.
+
+
+Generic Charting
+----------------
+
+Bugzilla's new charting feature allows you to display flexible summary charts,
+based on configurable data sets (bug 16009).
+
+
+Miscellaneous Improvements
+--------------------------
+
+- The "Assigned To" field on the new bug page is now prefilled with the default
+ component owner.
+
+- A bug alias column is now available in the buglist page.
+
+- Lists of bugs containing errors in the sanity check page now have a "view as
+ buglist" link in addition to the individual bug links.
+
+- Autolinkification Page - It's now possible to apply Bugzilla's comment
+ hyperlinking algorithm to any text you like. This should be useful for status
+ updates and other web pages which give lists of bugs. The bug links created
+ include the subject, status and resolution of the bug as a tooltip.
+
+- There are more <link> tags on the links toolbar for navigating quickly between
+ different areas.
+
+- Buglists are now available as comma-separated value files (CSV) and JavaScript
+ (JS) as well as HTML and RDF.
+
+- Keywords and dependencies can now be entered during initial bug entry.
+
+- A CSS id signature unique to each Bugzilla installation is now added to the
+ <body> tag on Bugzilla pages to allow custom end-user CSS to explicitly affect
+ Bugzilla.
+
+- Perl's path has been changed to a normal /usr/bin/perl from the original
+ legacy "bonsaitools" path specifier.
+
+- A new "always-require-login" parameter allows administrators to require a
+ login before being able to view any page, except the front page.
+
+- A developer may add an attachment, and also reassign a bug to himself as part
+ of that single action.
+
+- Bugzilla is now able to use the replication facilities provided by the
+ MySQL database to handle updates from the main database to the secondaries.
+
+- Mail handling is now between 125% to 175% faster.
+

+Code Changes Which May Affect Customizations
********************************************
-*** USERS UPGRADING FROM 2.10 OR EARLIER ***
-********************************************
-*** SECURITY ISSUES RESOLVED ***
-
-- Some security holes have been fixed where shell escape characters
- could be passed to Bugzilla, allowing remote users to execute
- system commands on the web server.
-
-*** IMPORTANT CHANGES ***
-
-- There is now a facility for users to choose the sort of
- notifications they wish to receive. This facility will
- probably be improved in future versions.
- (bug 17464)
-
-- "Changed" will no longer appear on the subject line of
- change notification emails. Because of this, you should
- change the subject line in your 'changedmail' and
- 'newchangedmail' params on editparams.cgi. The subject
- line needs to be changed from
-
- Subject: [Bug %bugid%] %neworchanged% - %summary%
-
- to:
-
- Subject: [Bug %bugid%] %neworchanged%%summary%
-
- or whatever is appropriate for the subject you are using
- on your system. Note the removal of the " - " in the
- middle.
- (bug 29820)
-
-*** Other changes of note ***
-
-- Bug titles now appear in the page title, and will hence
- display in the user's browser's bookmarks and history.
- (bug 22041)
-- Edit groups functionality (editgroups.cgi).
- (bug 25010)

- based on what duplicates you receive.
- (bug 25693)
-- When installing Bugzilla fresh, the administrator account is
- now created in checksetup.pl.
- (bug 17773)
-- Stored queries now show their name above the bug list, which
- helps the user when they have multiple bug lists in multiple
- browser windows. It also appears in the page title, and will
- hence display in the user's browser's bookmarks and history.
- (bug 52228)
-- All states and resolutions can now be collected for charting.
- (bug 6682)
-- A new search-engine-like "quick search" feature appears on

-- Querying on dependencies now works in the advanced query
- section of the query page.
- (bug 30823)
-- When a bug is marked as a duplicate, the reporter of the
- resolved bug is automatically added to the CC list of the
- open bug.
- (bug 28676)
-
-*** Bug fixes of note ***
-
-- Notification emails will now always be sent to QA contacts.
- Previously they wouldn't if you were using new email tech.
- (bug 30826)
-- When marking a bug as a duplicate, the duplicate stamp marked
- on the open bug will no longer be written too early (such as
- on mid-air collisions).
- (bug 7873)
-- Various bug fixes were made to the initial assignee and QA
- of a component. It is no longer possible to enter an
- invalid address. They will also now properly update when
- a user's email address is changed. Sanity check will now
- check these.
- (bug 66876)
-- Administrators can no longer create an email accounts that do
- not match the global email regular expression parameter.
- Previously this could occur and would cause sanity check
- errors.
- (bug 32971)
-- The resolution field can no longer become empty when the
- bug is resolved. This occurred because of midair collisions.
- (bug 49306)
-
-*******************************************
-*** USERS UPGRADING FROM 2.8 OR EARLIER ***
-*******************************************
-
-Release notes were not compiled for versions of Bugzilla before
-2.12.
-
-The file 'UPGRADING-pre-2.8' contains instructions you may
-need to perform in addition to running 'checksetup.pl' if you
-are running a pre 2.8 version.
+- A mechanism (called "Template Hooks") for third party extensions to plug into
+ existing templates without having to patch or replace distributed templates
+ has been added. More information on this can be found in the documentation.
+
+- Header output now uses CGI.pm, in a step towards enabling mod_perl
+ compatibility. This change will affect users that had customized charsets in
+ their CGI files: previously the charset had to be added everywhere that
+ printed the Content-Type header; now it only needs changing in one spot, in
+ Bugzilla/CGI.pm.
+
+- $::FORM{} and $::COOKIE{} are deprecated. Use the $cgi methods to access
+ them.
+
+- $::userid is gone in favor of Bugzilla->user->id
+
+- ConnectToDatabase() is gone (it's done automatically when you initialize the
+ Bugzilla object)
+
+- quietly_check_login() and confirm_login() are gone, use Bugzilla->login()
+ with parameters for whether the login is required or not.
+
+- Use Bugzilla->user->login in place of $::COOKIE{Bugzilla_login}
+
+- You can tell if there's a user logged in or not by checking if
+ Bugzilla->user exists rather than looking for $::userid==0
+
+
+Recommended Practice for the Upgrade
+************************************
+
+As always, please ensure you have run checksetup.pl after replacing the
+files in your installation.
+
+It is recommended that you view the sanity check page (sanitycheck.cgi) both
+before the upgrade and after running checksetup.pl after the upgrade, to see
+if there are any problems with your installation.
+
+It is also recommended that, if possible, you fix any problems you find
+immediately. Failure to do this may mean that Bugzilla will not work correctly.
+Be aware that if the sanity check page contains more errors after an upgrade,
+it doesn't necessarily mean there are more errors in your database, as
+additional tests are added to the sanity check over time, and it is possible
+that those errors weren't being checked for in the old version.
+
+As previously noted in the Dependency Requirements MySQL is now required to be
+at least version 3.23.41. This implies that all tables of type ISAM will be
+converted by the checksetup.pl script to MyISAM. As with any upgrade it is
+recommended to make a backup of the database, perhaps by using mysqldump.
+
+Example:
+
+ mysqldump -u root -p --databases bugs > bugs.db.backup
projects / thirdparty / bugzilla.git / commitdiff
