-* (bug 7831) Regression in AutoAuthenticate hook
-* Run PHP install version checks on update.php so command-line updaters see
-  new version requirements
-* Do a check for the PHP 5.0.x 64-bit bug, since this is much more disruptive
-  as of MW 1.8 than it used to be. Install or upgrade now aborts with a
-  warning and a request to upgrade.

-== MediaWiki 1.8.2 ==
+== Compatibility changes ==
 
-October 13, 2006
+=== Zend Optimizer ===
 
-MediaWiki 1.8.2 fixes several issues in the Fall 2006 snapshot release:
+A bug in some versions of PHP 5 and Zend Optimizer which was triggered under
+MediaWiki 1.8.x has been worked around by disabling some internal debugging
+features when Zend Optimizer is loaded. This should solve some common
+"blank page" problems.
 
-* (bug 7565) Fixed typos in German localisation
-* (bug 7562) Fix non-ASCII namespaces on Windows/XAMPP servers
+=== PHP 5.0 64-bit ===
 
+MediaWiki now checks for a condition where PHP 5.0.x corrupts array data
+on 64-bit systems and warns you to upgrade PHP to solve the problem. This
+bug causes Special: pages to fail on affected systems under MediaWiki 1.8
+and higher, and subtler data corruption on earlier versions.
 
-== MediaWiki 1.8.1 ==
+The only known workaround is to upgrade PHP to 5.1 or later, which you
+probably should do anyway for security reasons!
 
-October 11, 2006
+=== MySQL 5 ===
 
-MediaWiki 1.8.1 fixes several issues in the Fall 2006 snapshot release:
+MediaWiki should now install and run correctly on MySQL 5.0 and higher when
+MySQL's "strict mode" is enabled. (This is now the default for many Windows
+installations, though it seems to remain off by default on Unix.)
 
-* Fix PHP notice and estimates for dumpBackup.php and friends
-* Improved register_globals paranoia checks
-* (bug 7545) Fix PHP version check on install
-* Experimental web API disabled by default
-* Disable PHP exception backtrace printing unless $wgShowExceptionDetails
-  is set. Backtraces may contain sensitive information in function call
-  parameters.
+This fixes errors about "cannot default default value for BLOB/TEXT fields".
 
+=== ImageMagick ===
 
-== MediaWiki 1.8.0 ==
+Note that ImageMagick older than 6.x may no longer work for image resizing
+due to use of the -thumbnail option.

-This is the quarterly release snapshot for Fall 2006. While the code
-has been running on Wikipedia for some time, installation and upgrade
-bits may be less well tested. Bug fix releases may follow in the coming
-days or weeks.
+== Behavior changes ==
 
+=== Localized special pages ===
 
-MediaWiki is now using a "continuous integration" development model with
-quarterly snapshot releases. The latest development code is always kept
-"ready to run", and in fact runs our own sites on Wikipedia.
+The names of Special: pages can now be localized, so links and URLs to them
+are more legible in languages that aren't English.
 
-Release branches will continue to receive security updates for about a year
-from first release, but nonessential bugfixes and feature development happen
-will be made on the development trunk and appear in the next quarterly release.
+Not all languages have included localized names yet.
 
-Those wishing to use the latest code instead of a branch release can obtain
-it from source control: http://www.mediawiki.org/wiki/Download_from_SVN
+=== E-mail password ===
+
+Users are now required to set a new password for themselves when they first
+log in with a newly generated e-mailed password.
+
+Requesting passwords frequently is prevented to reduce abusive mailbombing.
+
+=== Undo revision ===
+
+An "undo" link now appears in diff view for easier reverting of older edits.
+When GNU diff3 is available for edit conflict merging, this can make it much
+easier to "undo" the changes of an older edit when there are surrounding
+changes elsewhere in the page.
+
+The changes must be manually reviewed and approved, as with conventional
+full-revision reverts.
+
+=== Blocking ===
+
+User blocks can be set to disable the automatic blocking of IP addresses the
+account logs in with.
+
+
+== Database changes ==
+
+* new 'redirect' table stores data on page redirects
+* new 'querycachetwo' table used for some cached special pages
+* 'ipblocks' table adds 'ipb_enable_autoblock'
+* 'recentchanges' table adds 'rc_old_len', 'rc_new_len' for size tracking
+* 'user' table has added 'user_newpass_time' and 'user_editcount' fields
+* some indexes have been updated on 'recentchanges'
 
 
 == Configuration changes ==
 
-* $wgUseETag, to enable/disable sending of HTTP ETag headers
-  (default: disabled)
-* $wgLegalTitleChars now includes '+' by default for better compatibility
-  with importing data dumps from Wikipedia
-* $wgDefaultUserOptions now includes all default option settings instead
-  of only overrides.
-
-
-== Major new features ==
-
-* (bug 7098) Add an option to disable/enable sending of HTTP ETag headers,
-  as it seems to result in broken behaviour in combination with Squid 2.6
-  (disabled by default).
-* (bug 550) Allow blocks on anonymous users only.
-* (bug 6420) Render thumbnails for DJVU images, support multipage DJVU display
-  on image pages. Added new 'page=' thumbnail option to select a page from a
-  multipage djvu for thumbnail generation.
-* Full Postgres support is now enabled. It requires version 8.1 or better, and 
-  needs to have both plpgsql and tsearch2 already installed.
-* (bug 6386) fix grammatical errors in danish naming of talk namespaces.
-
-== Changes since 1.7 ==
-
-* Introduced AjaxResponse object, superceding AjaxCachePolicy
-* Changes to sajax_do_call: optionally accept an element to fill instead of a
-  callback function; take the target function or element as a third parameter;
-  pass the full XMLHttpRequest object to the handler function, instead of just
-  the resultText value; use HTTP response codes to report errors.
-* (bug 6562) Removed unmaintained ParserXml.php for now
-* History paging overlap bug fixed
-* (bug 6586) Regression in "unblocked" subtitle
-* Don't put empty-page message into view-source when page text is blank
-* (bug 6587) Remove redundant "allnonarticles" message
-* Block improvements: Allow blocks on anonymous users only. Optionally allow 
-  or disallow account creation from blocked IP addresses. Prevent duplicate
-  blocks. Fixed the problem of expiry and unblocking erroneously affecting
-  multiple blocks. Fixed confusing lack of error message when a blocked user
-  attempts to create an account. Fixed inefficiency of Special:Ipblocklist in 
-  the presence of large numbers of blocks; added indexes and implemented an 
-  indexed pager.
-* (bug 6448) Allow filtering of Special:Newpages according to username
-* (bug 6618) Improve permissions/error detection in Special:Lockdb
-* Quick hack for extension testing: parser test doesn't create new message
-  cache object.
-* (bug 6299) Maintain parser's revision ID across recursive calls to fix
-  {{REVISIONID}} when Cite extension is used
-* (bug 6622) Removed deprecated function Image::newFromTitle
-* (bug 6627) Fix regression in Special:Ipblocklist with table prefix
-* Removed forced dereferencements (new() returns a reference in PHP5)
-* Note about $wgUploadSizeWarning using byte
-* (bug 6592) Add most viewed pages summary to Special:Statistics
-* Pre-strip characters ignored in IDNs from URLs so they can't be used

-  behavior is now a non-invasive check as with namespaceDupes.php
-* (bug 6660) Fix behaviour of EditPage::blockedPage() when the article does
-  not exist; now doesn't show the source box if the user hasn't provided it
-  (blocked mid-edit) and the page doesn't exist
-* Improve default value of "blockedtext"
-* (bug 6680) Added localisation for Dutch bookstore list (nl)
-* Renamed maintainace script redundanttrans.php to unusedMessages.php - clearer usage
-* Fix regression which allowed some blocked users to create additional accounts
-* (bug 6657) Fix Hungarian linktrail
-* (bug 6751) Fix preview of blanked section with edit on first preview option

-  introduced 'MediaWiki:Searchbutton'
-* Made lines from initialiseMessages() appear as list items during installation
-* Moved the bulk of the localisation data from the Language*.php files to the
-  Messages*.php files. Deleted most of the Languages*.php files.
-* Introduced "stub global" framework to provide deferred initialisation of core
-  modules. 
-* Removed placeholder values for $wgTitle and $wgArticle, these variables will
-  now be null during the initialisation process, until they are set by index.php
-  or another entry point.
-* Added DBA cache type, for BDB-style caches. 
-* Removed custom date format functions, replacing them with a format string in
-  the style of PHP's date(). Used string identifiers instead of integer
-  identifiers, in both the language files and user preferences. Migration should
-  be transparent in most cases.
-* Simplified the initialisation API for LoadBalancer objects.
-* Removed the broken altencoding feature.
-* Moved default user options and toggles from Language to User. Language objects
-  are still able to define default preference overrides and extra user toggles, 
-  via a slightly different interface.
-* Don't include the date option in the parser cache rendering hash unless
-  $wgUseDynamicDates is enabled.
-* Merged LanguageUtf8 with Language. Removed LanguageUtf8.php. 
-* Removed inclusion of language files from the bottom of Language.php. This is
-  now consistently done from Language::factory().

-* (bug 6929) Restore AutoAuthenticate hook
+Several configuration options have changed since 1.8:
+
+=== $wgEnableAPI ===
+
+The experimental machine API interface is now enabled by default, read-only.
+You can disable it by setting $wgEnableAPI = false; in LocalSettings.php.
+
+=== $wgPathInfo ===
+
+The use of PATH_INFO (the text after the script name in 'index.php/Blah')
+is controlled by the $wgUsePathInfo setting. This is now explicitly disabled
+for CGI, apache2filter, and ISAPI configurations of PHP, for more consistency
+with the autodetection from the installer.
+
+In some rarer configurations you may have to switch $wgUsePathInfo from false
+to true or, perhaps, from true to false to make things work properly if bad
+PATH_INFO data comes through the server.
+
+The wiki now tries to detect this condition and should show you an error
+message describing what to change instead of sending the browser into an
+infinite redirect loop.
+
+=== $wgScript and other path settings ===
+
+The following configuration variables are now automatically set in Setup.php
+if they are not overridden in LocalSettings.php:
+
+from $wgScriptPath:
+ + $wgScript
+ |  \- $wgArticlePath
+ + $wgRedirectScript
+ + $wgStylePath
+ + $wgUploadPath
+    \- $wgLogo
+     + $wgMathPath
+
+from $IP:
+ - $wgStyleDirectory
+ + $wgUploadDirectory
+   \- $wgMathDirectory
+    + $wgTmpDirectory
+    + $wgReadOnlyFile
+    + $wgFileCacheDirectory
+
+Newly generated configuration files will by default include only $wgScriptPath
+(hardcoded from the installer) and $IP (detected at runtime).
+
+Old configuration files which specify all these values explicitly should
+continue to work just fine, but if you use the defaults you can remove them
+to reduce clutter.
+
+=== $wgGroupPermissions ===
+
+The sysop group now holds the "autopatrol" and "ipblock-exempt" rights by
+default.
+
+"autopatrol" replaces the preference for marking ones own edits patrolled
+by default; users holding this permission will automatically have their
+edits patrolled, while others cannot mark their own edits as patrolled
+even if they have patrolling rights.
+
+"ipblock-exempt" excludes the user from IP blocks; accounts which are blocked
+explicitly by name will still be blocked, however. This is given to sysops
+to minimize annoyance from accidental "collateral damage"; remember that a
+sysop will be able to lift the block if they desire.
+
+The bot group now holds the "nominornewtalk" right. A user with this right
+will not trigger new message notifications when making minor edits to user
+talk pages. This is meant to minimize annoyance from maintenance bot
+processes.
+
+=== $wgUseWatchlistCache ===
+
+Watchlist caching has been removed. The feature was not maintained, and has
+been unnecessary since switching to the 'recentchanges' database table
+reduced server pressure for Wikipedia's watchlists.
+
+=== $wgBreakFrames ===
+
+MediaWiki in the past attempted to detect when it was embedded in a frameset
+and "break out" of it, assuming it to be hostile.
+
+This behavior is now disabled by default, but can be reenabled by setting
+$wgBreakFrames to true in LocalSettings.php.
+
+
+== New settings ==
+
+=== $wgVariantArticlePath ===
+
+For languages with script variant support (Chinese, Serbian, and others),
+it's possible to use alternate URL paths to select the variant for article
+display, setting $wgVariantArticlePath.
+
+Documentation for this setting would be useful.
+
+=== $wgMaxMsgCacheEntrySize ===
+
+The message cache can now skip items larger than a given size; this allows
+it to better handle the primary caching case when large CSS and JS blobs are
+present.
+
+=== $wgStyleVersion ===
+
+When making significant changes to skin stylesheets and JavaScript files,
+you can append a string to this variable to tweak the generated URLs,
+forcing newly rendered pages to bring in a fresh version despite server-
+or browser-side caching.
+
+Normally this will be set in the course of MediaWiki development, but
+if doing development on a custom skin you may wish to poke it as well.
+
+=== $wgRCShowChangedSize ===
+
+Special:Recentchanges and Special:Watchlist now show the number of bytes
+added or removed to an article to give an idea of the size of the edit.
+This information was previously available only in the IRC update feeds.
+
+To disable this site-wide, set $wgRCShowChangedSize to false.
+(Individual users can suppress the data in custom CSS.)
+
+Adjust $wgRCChangedSizeThreshold to trigger highlighting of particularly
+large changes.
+
+The formatting of the size figure can be adjusted through the
+[[MediaWiki:Rc-change-size]] message.
+
+=== $wgQueryCacheLimit ===
+
+The number of rows stored for "expensive" special pages in miser mode
+can now be adjusted up or down from the default 1000.
+
+=== $wgDisableQueryPageUpdate ===
+
+Individual "expensive" special pages can be skipped in processing by
+updateSpecialPages if added to this list.
+
+=== $wgSorbsUrl ===
+
+The base hostname for the DNS-based proxy blacklist can now be overridden
+when $wgEnableSorbs is set, to use a different blacklist instead of SORBS.
+The blacklist would need to respond the same was as SORBS; any positive
+response will be taken as a proxy.
+
+=== $wgAjaxWatch ===
+
+Experimental AJAX mode for the watch/unwatch tabs to execute inline.
+Does not include the UI messages describing how to reach the watchlist,
+so you may not want it on a general-audience site just yet.
+
+=== $wgParserTestFiles ===
+
+MediaWiki's parser test suite can now be expanded with additional test
+files. Custom extensions can add their test files to this array, and
+they will be run along with the main tests by maintenance/parserTests.php
+
+

+  styling (class="mw-templatesUsedExplanation").
+* Added {{#special:}} parser function, to give the local default title for 
+  special pages
+* (bug 7766) Remove redundant / from AJAX requests, can break some servers

+* Various fixes related to the blocking change re: autoblocks. On inserting
+  an IP block, the ipb_enable_autoblock field is now automagically blanked,
+  because it doesn't make any sense for an IP. Additionally, IP blocks
+  without the ipb_enable_autoblock option no longer show up as "autoblock

+* (bug 7774) MATH: aded more amstex functions

+  recently used IP of a user when they are blocked.
+* Add an index on (rc_user_text,rc_timestamp) on the recentchanges table. This will 
+  make CheckUser.php and the new retroactive autoblock functionality faster.

+  with compression or legacy encoding
+* (bug 6737) Fixes for MySQL 5 schema in strict mode

+  Additional tables 'testrun' and 'testitem' are in maintenance/testRunner.sql,
+  source this and pass --record option to parserTests.php

+  run along with the main batch.
+* Run PHP install version checks on update.php so command-line updaters see
+  new version requirements
+* Do a check for the PHP 5.0.x 64-bit bug, since this is much more disruptive
+  as of MW 1.8 than it used to be. Install or upgrade now aborts with a
+  warning and a request to upgrade.
+* (bug 6440) Updated indexes to improve backlinking queries (links, templates, images)
+* Switched 'anon-only' block mode to default for IP blocks
+* (bug 3687, 7892) Add distinct heading for media files in category display,

+* (bug 3315) Provide rollback link directly on history page.
+* Replace 'old-revision-navigation' message with 'revision-info' and
+  'revision-nav' messages, wrapped in divs with appropriate id's.
+* (bug 4178) MediaWiki:Common.js will now be included for all users if
+  $wgUseSiteJs is enabled, in addition to (if applicable) MediaWiki:Monobook.js
+  and user JS subpages.
+* (bug 7918) "Templates used on this page" changes during preview to reflect
+  any added or removed templates, and works as expected for section edits.
+* (bug 7919) "Templates used on this page" is now shown for read-only pages.

+  on current page instead of loading the latest version.
+* (bug 7970) Use current connection explicitly on Database::getServerVersion
+* (bug 2001) Tables with class="sortable" can now be dynamically sorted via
+  JavaScript.
+* Added autosummary for new pages with 500 or less characters, and refactor
+   the autosummary code so it's all done in one function. doEdit is getting too
+   big!
+* (bug 7554) The correct MIME type for SVG images is now displayed on the
+  image page (image/svg+xml, not image/svg).
+* (bug 7883) Added autoblock whitelisting feature, using which specific ranges
+   can be protected from autoblocking. These ranges are specified, in list format,
+   in the autoblock_whitelist system message.
+* Added placeholders for text injection by hooks to EditPage.php
+* (bug 8009) Automatic edit summary for redirects is not filled for edits in existing pages
+* Installer support for experimental MySQL 4.1/5.0 binary-safe schema
+* Use INSERT IGNORE for db-based BagOStuff add/insert, for more memcache-like
+  behavior when keys already exist on add (instead of dying with an error...)
+* Add a hook 'UploadForm:initial' before the upload form is generated, and two
+  member variable for text injection into the form, which can be filled by the hooks.
+* (bug 6295) Add a "revision patching" functionality, where an edit can be undone
+  (with a functionality similar to diff rev1 rev2 | patch -R rev3 -o rev3).
+  This is triggered by including &undo=revid in an edit URL. A link to a URL
+  that will undo a given edit is shown on NEW revision headers on diff pages.
+  The link leads to a "Show Changes" page showing what will be done to undo the 
+  edit.
+* Fix display of link in "already rolled back" message for image/category pages
+* (bug 6016) Left-aligned images should stack vertically, like right-aligned
+  images, not horizontally.
+* Patch from LeonWP: added UploadForm:BeforeProcessing hook in SpecialUpload.php
+* Add AuthPluginSetup hook to override $wgAuth after configuration
+* Fix regression in authentication hook auto-creation on login
+* (bug 8110) Allow spaces in ISBNs
+* (bug 8024) Introduce "send me copies of emails I send to others" preference
+* Added 'EditPage::attemptSave' hook before an article is saved.
+* (bug 8083) Applied patch for sk localisation
+* Add a backslash character to the edit token, to prevent edits via certain
+  broken proxies that mangle such characters in form submissions
+* (bug 7461) Allow overwriting pages using importTextFile.php
+* (bug 7946) importTextFile.php doesn't perform pre-save transform
+* (bug 8117) {{REVISIONTIMESTAMP}} showed weird default if $wgLocalTZoffset set;
+  now uses current time for previews and if timestamp can't be loaded from DB
+* {{REVISIONTIMESTAMP}} now uses site local timezone instead of user timezone
+  to ensure consistent behavior
+* {{REVISIONTIMESTAMP}} and friends should now work on non-MySQL backends
+* (bug 7671) Observe canonical media namespace prefix in Linker::formatComment
+* Added js variable wgCurRevisionId to the output
+* (bug 8141) Cleanup of Parser::doTableStuff, patch by AzaTht
+* (bug 8042) Make miser mode caching limits settable via $wgQueryCacheLimit
+  instead of hardcoding to 1000
+* Enable QueryPage classes to override list formatting
+* (bug 5485) Show number of intervening revisions in diff view
+* (bug 8100) Fix XHTML validity in Taiwanese localization
+* Added redirect to section feature. Use it wisely.
+* Added a configuration variable allowing the "break out of framesets" feature 
+  to be switched on and off ($wgBreakFrames). Off by default.
+* Allow Xml::check() $attribs parameter to override 'value' attribute
+* DB schema change: added two columns (rc_old_len and rc_new_len) to the recentchanges table to store
+  the text lengths before and after the edit
+* (bug 1085) Made Special:Recentchanges show the character difference between the changed revisions
+* Removed a redundant <strong> tag from diff pages that was causing display issues for some users
+* (bug 8203) The keyboard shortcut for "log out" was removed, because users were pressing it
+  when they intended to press the shortcut for "preview".
+* (bug 8148) Handle non-removable output buffers gracefully when cleaning
+  buffers for HTTP 304 responses, StreamFile, and Special:Export.
+  Duplicated code merged into wfResetOutputBuffers() and wfClearOutputBuffers()
+* Special:AllPages : 'next page' link now point to the first title of the next
+  chunk instead of pointing to the last title of current chunk.
+* (bug 4673) Special:AllPages : add a 'previous' link (new message 'prevpage')
+* (bug 8121) wfRandom() was not between 0 and 1
+* Add static method Parser::createAssocArgs($args), so parser functions can
+  use the same code to parse arguments as the templates do.
+* Change behavior of logins using the temporary e-mailed password (as stored
+  in user_newpassword hash field). Instead of just logging in silently and
+  leaving the previous user_password field in place indefinitely, the user
+  is now prompted to set a new password.
+  
+  The password-changing form is at Special:Resetpass; currently it's only
+  usable for changing from the temporary password during login, but it
+  could perhaps be generalized, replacing the subform in preferences.
+  
+  Once the new password is set successfully, the temporary password is wiped
+  so it cannot be used to login a second time, and the login process
+  is completed.
+* Suppress 'mail new password' button on login form if $wgAuth forbids
+  changing user passwords; it wouldn't work very well...
+* Consolidate password length checks and $wgAuth manipulation into
+  User::setPassword() to avoid duplicate code in different places
+  that set passwords.
+* User::setPassword() now throws PasswordError exceptions if the password
+  is illegal or cannot be set via $wgAuth. These can be caught and a human-
+  readable error message displayed by UI code.
+* Added Title::isSubpage()
+* (bug 8241) Don't consider user pages of User:Foo.css to be CSS subpages
+* Set an explicit class on framed thumbnail inner divs and images, changed some 
+  CSS to use these instead of using descendent selectors.
+* Accept null parameter to User::setPassword() as indicating the password
+  field should be cleared to an unusable state. Login will only be possible
+  after the password is reset, for instance by e-mail.
+* (bug 6394) Invalidate the password set for "by e-mail" account creations
+  to avoid accidental empty password creations.
+* Made the show change size function work on page moves, page creations, and 
+  log entries. Also fixed it in the javascript recentchanges.
+* (bug 8239) correctly get 50 new contributions when clicking '(50 next)'
+* (bug 2259) Fix old regression where e-mail addresses were no longer
+  confirmed on login with mailed password.
+* Add a notification about the confirmation mail sent during account
+  creation, so people don't immediately go off to request a second one.
+* Add a warning on Special:Confirmemail if a code was already sent and has
+  not yet expired.
+* Add user_editcount field to provide data for heuristics on account use.
+  Incremented on edit, with lazy initialization from past revision data.
+  Can batch-initialize with maintenance/initEditCount.php (not yet friendly
+  to replication environments, this will do all accounts in one query).
+* Allow raw SQL subsections in Database::update() SET portion as well as
+  for WHERE portion. Handy for increments and such.
+* User::getOption now accept a default value to override default user values
+  this makes it consistent with WebRequest::get* methods. Corrected code in
+  various places accordingly.
+* (bug 8264) Fix JavaScript global vars for XHTML mode
+* Make $wgSiteNotice value wikitext again, for consistency with editable
+  MediaWiki:Sitenotice and MediaWiki:Anonnotice.
+* (bug 8044) When redirecting from the canonical name of the special page
+  to the localised one, parameters/subpages are omitted
+* (bug 8164) Special:Booksources should use GET for form submission
+* Rewrite Special:Booksources to clean up interface and remove redundant code
+* (bug 7925) Change Special:Allmessages message name filter javascript to be
+  a bit more responsive and easier on the CPU
+* (bug 4488) Support watching pages on deletion; introduces new user preference
+* Minor restructuring of Special:Preferences; "watch pages I edit" and "watch
+  pages I create" options now accessible under "Watchlist" options
+* (bug 8153) <nowiki> doesn't work in site notice
+* (bug 6690) wfMsgNoTrans() transforms messages
+* (bug 8274) Wrap edit tools in a <div> with a specified class
+* Detect PHP 5.0.x 64-bit bug and abort in WebStart.php; too many things break
+  mysteriously otherwise (detection code copied from install-utils.inc)
+* (bug 8295) Change handling of <center> tags in doBlockLevels() to match that
+  of <div>
+* (bug 8110) Make magic ISBN linking stricter: only match ten-digit sequences
+  (plus optional ISBN-13 prefix) with no immediately following alphanumeric
+  character, disallow multiple consecutive internal redirects
+* (bug 2785) Accept optional colon prefix in links when formatting comments
+* Don't show "you can view and copy the source of this page" message for
+  pages which don't exist
+* (bug 8310) Blank line added to top of 'post' when page is blank
+* (bug 8109) Template parameters ignored in "recentchangestext"
+* Gracefully skip redirect-to-fragment on WebKit versions less than 420;
+  it messes up on current versions of Safari but is ok in the latest
+  nightlies. Checking the version number will allow it to automatically
+  work when new releases of Safari appear.
+* Fix regression in thumb styles; size and padding didn't match with
+  new arrangement.
+* (bug 8333) Fix quick user data update on login password change on
+  replication database setups. User data is now pulled from master
+  instead of slave in User::loadFromDatabase, ensuring that it is
+  fresh and accurate when read and then saved back into cache.
+  This was breaking with the Special:Rename operation which
+  automatically logs the user in with the new password after changing
+  it; pulling from slave meant the record was often not the updated
+  one.
+* (bug 8335) Set image width to the first valid parameter found.
+* (bug 8350) Fix watchlist viewing bug when using Postgres.
+* (bug 6603) When warning about invalid file extensions, output the bit
+  of the extension we actually checked
+* (bug 7669) Drop defaults on BLOB/TEXT columns for better compatibility
+  with MySQL's strict mode, often enabled by the Windows installer.
+  The defaults are ignored anyway when strict mode is off...
+* (bug 7685) Use explicit values for ar_text and ar_flags when deleting,
+  for better compatibility with MySQL's strict mode
+* Update default interwiki values to reflect changed location of ursine:
+* (bug 5411) Remove autopatrol preference
+* Users who have the "autopatrol" permission will have their edits marked as
+  patrolled automatically
+* Users who do not have the "autopatrol" permission will no longer be able
+  to mark their own edits as patrolled
+* Introduce 'PingLimiter' hook; see docs/hooks.txt for more information
+* (bug 532) Tweaked alt text for some interface messages
+* (bug 8231) Gave useful alt text to the main <img> on image pages
+* (bug 371) Remove alt text for "Enlarge" icon on thumbnails
+* Initialize user_editcount to 0 instead of NULL for newly created accounts
+* (bug 3696) Strip LRM and RLM characters from titles to work around the
+  problem some people have where titles cut-and-pasted from lists include
+  the bidi override characters appended to the lists.
+  A more thorough blacklist for forbidden and translatable characters would
+  be wise, though, as might a cleaner method for the lists in the first place.
+* Fix regression in email password resets on read-restricted sites
+* Set tabindex on fields in deletion form so you don't have to tab through
+  the links in the sitenotice
+* (bug 8271) Show full time and date on viewer for individual deleted
+  revisions
+* (bug 8214) Output file size limit and actual file size in appropriate units
+  on Special:Upload
+* (bug 8016) Purge objectcache table during upgrade processes - use the --nopurge
+  option to prevent this when running maintenance/update.php
+* (bug 7612) Remove superfluous link to Special:Categories from result items
+  on Special:Mostcategories
+* {{PLURAL:}} now handles formatted numbers correctly
+* (bug 8331) Added the change size value to watchlists; therefore made
+  watchlists use RecentChange::newFromRow() instead of newFromCurRow()
+* (bug 8351) Fix undo for simple reverts
+* (bug 6856) User::clearNotification() does not respect read-only mode
+* (bug 6853) Use a checkbox on the installer form to indicate that a superuser
+  account should be used; this is clearer than the old check which relied on
+  the password never being an obscure value
+* Remove old unused watchlist cache, which was a leftover from the old schema
+  where watchlists were more expensive to generate
+* Minor cosmetic changes to Special:Userrights
+* Added wgCanonicalSpecialPageName to JavaScript variables
+* Fix image deleting when using Postgres.
+* Output both source and destination titles in maintenance/moveBatch.php
+* Added basic parser tests for language variants 
+* Enable selflinks and categories to be written in some of the language variants
+* Prevent conversion of JavaScript code in language variants
+* Output software version number in maintenance/parserTests.php
+* (bug 7169) Use Ajax to watch/unwatch articles if enabled
+* Make variant table caching a little more robust, using main language code
+  in cache key. Probably this is still a bit wonky, though. Was breaking
+  parser tests when Chinese tables were getting loaded into Serbian code.
+* (bug 8380) Be nicer about blank lines in deleteBatch.php
+* (bug 8401) Fix regression in SORBS lookup for some DNS setups
+* Use raw file descriptor in posix_isatty() check to avoid warning on
+  Linux systems with at least some versions of PHP
+* (bug 5908) Allow overriding the default category sort key for all items on
+  a page using {{DEFAULTSORT}}
+* (bug 6449) Throw a more definitive error message when installation fails
+  due to an invalid database name
+* (bug 5827) Use full text for option link labels on Special:Watchlist
+* (bug 8018) Allow hiding minor edits from the watchlist
+* (bug 8427) MonoBook RTL IE 7.0 tweaks failed when sidebar's navigation
+  section is renamed; no longer relies on first section name
+* Stabilize client-side table sorting even if the underlying Javascript sort()
+  implementation is unstable
+* Add hook for extensions to add user information to the panel in preferences,
+  next to the user name and ID.
+* (bug 8392) Display protection status of transcluded pages in the edit page
+  template list. Patch by Fyren, with i18n naming tweak.
+* Fix for interwiki transclusion where target wiki uses query string for title
+* Resolve namespaces on interwiki Title objects using canonical namespace names
+  if possible (should not happen, though, outside interwiki transclusion... and
+  maybe not even then, but it does)
+* (bug 8447) Fix SQL typo breaking non-default $wgHitcounterUpdateFreq
+* Do not allow previews of deleted images to be cached
+* Add global variable $wgDefaultLanguageVariant used to set the default language 
+  variant of a wiki to something different than the main language code
+* Add 'variant' option to parserTests - runs test with the given variant as
