== Notes ==
MediaWiki is now using a "continuous integration" development model with
it from source control: http://www.mediawiki.org/wiki/Download_from_SVN
Changes since 1.12.0rc1: * (bug 13359) Double-escaping in Special:Allpages* Localization updates. == MediaWiki 1.12.0rc1 == This is a release candidate of the Winter 2008 quarterly snapshot releaseof MediaWiki. MediaWiki is now using a "continuous integration" development model withquarterly snapshot releases. The latest development code is always kept"ready to run", and in fact runs our own sites on Wikipedia. Release branches will continue to receive security updates for about a yearfrom first release, but nonessential bugfixes and feature developmentswill be made on the development trunk and appear in the next quarterly release. Those wishing to use the latest code instead of a branch release can obtainit from source control: http://www.mediawiki.org/wiki/Download_from_SVN === Configuration changes in 1.12 ===* Marking edits as bot edits with Special:Contributions?bot=1 now requires the markbotedit permission, rather than the rollback permission previously used. This permission is assigned by default to the sysop group.* MediaWiki now checks if serialized files are out of date. New configuration variable $wgCheckSerialized can be set to false to enable old behavior (i.e. to not check and assume they are always up to date)* The rollback permission can now be rate-limited using the normal mechanism.* New configuration variable $wgExtraLanguageNames* Behaviour of $wgAddGroups and $wgRemoveGroups changed. New behaviour:* * Granting the userrights privilege allows arbitrary changing of rights.* * Without the userrights privilege, a user will be able to add and/or remove the groups specified in $wgAddGroups and $wgRemoveGroups for any groups they are in.* New permission userrights-interwiki for changing user rights on foreign wikis.* $wgImplictGroups for groups that are hidden from Special:Listusers, etc.* $wgAutopromote: automatically promote users who match specified criteria* $wgGroupsAddToSelf, $wgGroupsRemoveFromSelf: allow users to add or remove themselves from specified groups via Special:Userrights.* When $wgUseTidy has been enabled, PHP's Tidy module is now used if it is present, in preference to an external Tidy executable which may or may not be present. To force use of external Tidy even when the PHP module is available, set $wgTidyInternal to false. === New features in 1.12 ===* (bug 10735) Add a warning for non-descriptive filenames at Special:Upload* Add {{filepath:}} parser function to get full path to an uploaded file, complementing {{fullurl:}} for pages.* (bug 11136) If using Postgres, search path is explicitly set if wgDBmwschema is not set to 'mediawiki', allowing multiple mediawiki instances per user.* (bug 11151) Add descriptive <title> to revision history page* (bug 5412) Add feed links for the site to all pages* (bug 11353) Add ability to retrieve raw section content via action=raw* (bug 6909) Show relevant deletion log lines when uploading a previously deleted file* On SkinTemplate based skins (like MonoBook), omit confusing "edit"/"view source" tab entirely if the page doesn't exist and the user isn't allowed to create it* Clarify instructions given when an exception is thrown* AuthPlugin added strictUserAuth() method to allow per-user override of the strict() authentication behavior.* (bug 7872) Deleted revisions can now be viewed as diffs showing changes against the previous revision, whether currently deleted or live.* Added tooltips for the "Go" and "Search" buttons* (bug 11649) Show input form when Special:Whatlinkshere has no parameters* isValidEmailAddr hook added to User method of that name, to allow, e.g., re- stricting e-mail addresses to a specific domain* Removed "Clear" link in watchlist editor tools, as people were afraid to click it. Existing clear links will fall back to the raw editor, which is very easy to clear your watchlist with.* (bug 1405) Add wgUseNPPatrol option to control patroling for new articles on Special:Newpages* LogLine hook added to allow formatting custom entries in Special:Log.* Support for Iranian calendar* (bug 1401) Allow hiding logged-in users, bots and patrolled pages on Special:Newpages* ChangesListInsertArticleLink hook added for adding extra article info to RC.* MediaWikiPerformAction hook added for diverting control after the main globals have been set up but before any actions have been taken.* BeforeWatchlist hook added for filtering or replacing watchlist.* SkinTemplateTabAction hook added for altering the properties of tab links.* OutputPage::getRedirect public method added.* (bug 11848, 12506) Allow URL parameters 'section', 'editintro' and 'preload' in Special:Mypage and Special:Mytalk* Add ot=raw to Special:Allmessages* Support for Hebrew calendar* Support for Hebrew numerals in dates and times* (bug 11315) Signatures can be configured in [[MediaWiki:Signature]] and [[MediaWiki:Signature-anon]]* Signatures for anonymous users link to Special:Contributions page rather than user page* Added --override switch for disabled pages in updateSpecialPages.php* Provide a unique message (ipb_blocked_as_range) if unblock of a single IP fails because it is part of a blocked range.* (bug 3973) Use a separate message for the email content when an account is created by another user* dumpTextPass.php can spawn fetchText.php as a subprocess, which should restart cleanly if database connections fail unpleasantly.* (bug 12028) Add Special:Listbots as shortcut for Special:Listusers/bot* (bug 9633) Add a predefined list of delete reasons to the deletion form* Show a warning message when creating/editing a user (talk) page but the user does not exists* (bug 8396) Ignore out-of-date serialised message caches* (bug 12195) Undeleting pages now requires 'undelete' permission* (bug 11810) Localize displayed semicolons* (bug 11657) Support for Thai solar calendar* (bug 943) RSS feed for Recentchangeslinked* Introduced AbortMove hook* (bug 2919) Protection of nonexistent pages with regular protection interface.* Special:Upload now lists permitted/prohibited file extensions.* Split ambiguous filetype-badtype message into two new messages, filetype-unwanted-type and filetype-banned-type.* Added link to the old title in Special:Movepage* On Special:Movepage, errors are now more noticeable.* It is now possible to change rights on other local wikis without the MakeSysop extension* Add HTML ID's mw-read-only-warning and mw-anon-edit-warning to warnings when editing to allow CSS styling.* Parser now returns list of sections* When a user is prohibited from creating a page, a title of "View source" makes no sense, and there should be no "Return to [[Page]]" link.* (bug 12486) Protected titles now give a warning for privileged editors.* (bug 9939) Special:Search now sets focus to search input box when no existing search is active* For Special:Userrights, use GET instead of POST to search for users.* Allow subpage syntax for Special:Userrights, i.e., Special:Userrights/Name.* When submitting changes on Special:Userrights, show the full form again, not just the search box.* Added exception hooks* (bug 12574) Allow bots to specify whether an edit should be marked as a bot edit, via the parameter 'bot'. (Default: '1')* (bug 12536) User should be able to get MediaWiki version from any page* (bug 12622) A JavaScript constant to declare whether api.php is available* Add caching to the AJAX search* Add APCOND_INGROUPS* Add DBA caching to installer* (bug 12585) Added a bunch of parameters to the revertpage message* Support redirects in image namespace* (bug 10049) Prefix index search and namespaces in Special:Withoutinterwiki* (bug 12668) Support for custom iPhone bookmark icon via $wgAppleTouchIcon* Add option to include templates in Special:Export.* (bug 12655) Added $wgUserEmailUseReplyTo config option to put sender address in Reply-To instead of From for user-to-user emails. This protects against SPF problems and privacy-leaking bounce messages when using mailers that set the envelope sender to the From header value.* (bug 11897) Add alias [[Special:CreateAccount]] & [[Special:Userlogin/signup]] for Special:Userlogin?type=signup* (bug 12214) Add a predefined list of delete reasons to the file deletion form* Merged backends for OpenSearch suggestions and AJAX search.

The main effect of this for the user is that the rules for uncovered syntaxhave changed. Uncovered main-pass syntax, such as HTML tags, are now generally valid, whereaspreviously in some cases they were escaped. For example, you could have "<ta" inone template, and "ble>" in another template, and put them together to make avalid <table> tag. Previously the result would have been "<table>". Uncovered preprocessor syntax is generally not recognised. For example, if youhave "{{a" in Template:A and "b}}" in Template:B, then "{{a}}{{b}}" will beconverted to a literal "{{ab}}" rather than the contents of Template:Ab. Thiswas the case previously in HTML output mode, and is now uniformly the case inthe other modes as well. HTML-style comments uncovered by template expansionwill not be recognised by the preprocessor and hence will not prevent templateexpansion within them, but they will be stripped by the following HTML securitypass. Bug 5678 has been fixed. This has a number of user-visible effects related tothe removal of this double-parse. Please see the wiki page for examples. Message transformation mode has been removed, and replaced with "preprocess"mode. This means that some MediaWiki namespace messages may need to be updated,especially ones which took advantage of the terribly counterintuitive behaviourof the former message mode. The header identification routines for section edit and for numbering sectionedit links have been merged. This removes a significant failure mode and fixes awhole category of bugs (tracked by bug #4899). Wikitext headings uncovered bytemplate expansion will still be rendered into a heading tag, and will get an entry in the TOC, but will not have a section edit link. HTML-style headings will also not have a section edit link. Valid wikitext headings present in the template source text will get a template section edit link. This is a major break from previous behaviour, but I believe the effects are almost entirely beneficial. The main motivation for making these changes was performance. The new two-passpreprocessor can skip "dead branches" in template expansion, such as unfollowed#switch cases and unused defaults for template arguments. This provides asignificant performance improvement in template-heavy test cases taken fromWikipedia. Parser function hooks can participate in this performance improvementby using the new SFH_OBJECT_ARGS flag during registration. The pre-expand include size limit has been removed, since there's no efficientway to calculate such a figure, and it would now be meaningless for performanceanyway. The "preprocessor node count" takes its place, with a generous defaultlimit. The context in which XML-style extension tags are called has changed, soextensions which make use of the parser state may need compatibility changes. The new preprocessor syntax has been documented in Backus-Naur Form at: http://www.mediawiki.org/wiki/Preprocessor_ABNF The ExpandTemplates extension now has the ability to generate an XML parse tree from wikitext source. This parse tree corresponds closely to the grammardocumented on that page. === API changes in 1.12 ===

== Compatibility ==
MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
http://bugs.php.net/bug.php?id=34879
Upgrade affected systems to PHP 5.1 or higher.
MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
== Upgrading ==
1.12 has several database changes since 1.11, and will not work without schema
updates.
If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
new database fields are filled with data.
If upgrading from before 1.11, and you are using a wiki as a commons repository,
make sure that it is updated as well. Otherwise, errors may arise due to
database schema changes.
If you are upgrading from MediaWiki 1.4.x or earlier, some major database
changes are made, and there is a slightly higher chance that things could
break. Don't forget to always back up your database before upgrading!
See the file UPGRADE for more detailed upgrade instructions.
=== Caveats ===
Some output, particularly involving user-supplied inline HTML, may not
produce 100% valid or well-formed XHTML output. Testers are welcome to
set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
cases, but this is not recommended on live sites. (This must be set for
MathML to display properly in Mozilla.)
For notes on 1.11.x and older releases, see HISTORY.
