8 THIS IS NOT A RELEASE YET
9
10 MediaWiki is now using a "continuous integration" development model with
11 quarterly snapshot releases. The latest development code is always kept
12 "ready to run", and in fact runs our own sites on Wikipedia.
13
14 Release branches will continue to receive security updates for about a year
15 from first release, but nonessential bugfixes and feature developments
16 will be made on the development trunk and appear in the next quarterly release.
17
18 Those wishing to use the latest code instead of a branch release can obtain
19 it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

22 * $wgScriptModifiedMsgCheck Checks the mediawiki namespace recent changes to
23 ensure a updated urid for script-loader
24 * $wgScriptModifiedCheck Checks script file modified time for unique request id)
25 * $wgEnableAsyncDownload (lets you disable Async download for windows.
26 Hopefully we will remove this configuration var soon)
27 * $wgEnableFirefogg enable support for firefogg extension, firefogg supports
28 in-browser transcoding, chunk uploads and client side hash checking.

35 (script-loader helper) and use new interfaces for upload
36 * $wgEnableScriptLoaderJsFile if we support grabbing js files with the script
37 loader. By default we only grab classes in $wgJSAutoloadClasses
38 * $wgEnableScriptMinify if you want the script loader to minify js
39 * $wgEnableScriptLocalization if you want the script loader to do msg lookups
40 * $wgMwEmbedDirectory the path to MwEmbed Directory (maybe we can depreciate
41 this. Was used when mwEmbed was going to be an extension.

43 * $wgPhpCliPath Path to php-cli for spinning up background php processes
44 * (bug 18222) $wgMinimalPasswordLength default is now 1

54 * $wgDevelopmentWarnings can be set to true to show warnings about deprecated
55 functions and other potential errors when developing.

60 if the $wgContLang does not have variant, then the $wgLang is used instead.

69 needs to be set explicitly, or $wgCacheDirectory needs to be set instead.
70 * $wgLocalMessageCache has been removed. Instead, set $wgUseLocalMessageCache
71 to true

154 * Expanded the number of variables which can be set in the extension messages
155 files.
156 * Added a feature to allow per-article process pool size control for the parsing

733
734 == Compatibility ==
735
736 MediaWiki 1.16 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
737
738 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
739 http://bugs.php.net/bug.php?id=34879
740 Upgrade affected systems to PHP 5.1 or higher.
741
742 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
743 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
744
745
746 == Upgrading ==
747
748 1.16 has several database changes since 1.15, and will not work without schema
749 updates.
750
751 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
752 ry, make sure that it is updated as well. Otherwise, errors may arise due to
753 database schema changes.
754
755 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
756 new database fields are filled with data.
757
758 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
759 changes are made, and there is a slightly higher chance that things could
760 break. Don't forget to always back up your database before upgrading!
761
762 See the file UPGRADE for more detailed upgrade instructions.
763
764
765 === Caveats ===
766
767 Some output, particularly involving user-supplied inline HTML, may not
768 produce 100% valid or well-formed XHTML output. Testers are welcome to
769 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
770 cases, but this is not recommended on live sites. (This must be set for
771 MathML to display properly in Mozilla.)
772
773 For notes on 1.15.x and older releases, see HISTORY.
774
775
776 === Online documentation ===
777
778 Documentation for both end-users and site administrators is currently being
779 built up on MediaWiki.org, and is covered under the GNU Free Documentation
780 License (except for pages that explicitly state that their contents are in
781 the public domain) :
782
783 http://www.mediawiki.org/wiki/Documentation
784
785
786 === Mailing list ===
787
788 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
789 wikitech-l list:
790
791 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
792
793 A low-traffic announcements-only list is also available:
794
795 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
796
797 It's highly recommended that you sign up for one of these lists if you're
798 going to run a public MediaWiki, so you can be notified of security fixes.

801 === IRC help ===

803 There's usually someone online in #mediawiki on irc.freenode.net
