1 = MediaWiki release notes =
3 Security reminder: MediaWiki does not require PHP's register_globals
4 setting since version 1.2.0. If you have it on, turn it *off* if you can.
8 THIS IS NOT A RELEASE YET
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.
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.
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
21 === Configuration changes in 1.16 ===
23 * $wgEnableFirefogg enable support for firefogg extension, firefogg supports
24 in-browser transcoding, chunk uploads and client side hash checking.
25 * $wgEnableTemporalOggUrls enable oggz_chop support a server side ogg seeking

31 mv_embed.js (script-loader helper) and use new interfaces for upload

33 loader. By default we only grab classes in $wgJSAutoloadClasses
34 * $wgEnableScriptMinify if you want the script loader to minify js
35 * $wgEnableScriptLocalization if you want the script loader to do msg lookups
36 * $wgMwEmbedDirectory the path to MwEmbed Directory (maybe we can depreciate
37 this. Was used when mwEmbed was going to be an extension.

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

50 * $wgDevelopmentWarnings can be set to true to show warnings about deprecated
51 functions and other potential errors when developing.
52 * Subpages are now enabled in the MediaWiki namespace by default. This is
53 mainly a cosmetic change, and does not in any way affect the MessageCache,
54 which was already effectively treating the namespace as if it had subpages.
55 * (bug 10837) $wgVariant is a user variant selected in the user's preferences
56 if the $wgContLang does not have variant, then the $wgLang is used instead.

61 * Added $wgCacheDirectory, to replace $wgFileCacheDirectory,
62 $wgLocalMessageCache, and any other local caches which need a place to put

65 needs to be set explicitly, or $wgCacheDirectory needs to be set instead.
66 * $wgLocalMessageCache has been removed. Instead, set $wgUseLocalMessageCache
68 * Removed $wgEnableSerializedMessages and $wgCheckSerialized. Similar

79 * $wgMemoryLimit has been added, default value '50M'
80 * $wgExtraRandompageSQL is deprecated, the SpecialRandomGetRandomTitle hook
81 should be used instead

129 * Added a PHP port of CDB (constant database), for improved local caching when
130 the DBA extension is not available.
131 * Introduced a new system for localisation caching. The system is based around

134 set $wgCacheDirectory to get a faster CDB-based implementation.
135 * Expanded the number of variables which can be set in the extension messages
137 * Added a feature to allow per-article process pool size control for the parsing

560 MediaWiki 1.16 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
562 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
563 http://bugs.php.net/bug.php?id=34879
564 Upgrade affected systems to PHP 5.1 or higher.
566 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
567 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
572 1.16 has several database changes since 1.15, and will not work without schema
575 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
576 ry, make sure that it is updated as well. Otherwise, errors may arise due to
577 database schema changes.
579 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
580 new database fields are filled with data.
582 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
583 changes are made, and there is a slightly higher chance that things could
584 break. Don't forget to always back up your database before upgrading!
586 See the file UPGRADE for more detailed upgrade instructions.
591 Some output, particularly involving user-supplied inline HTML, may not
592 produce 100% valid or well-formed XHTML output. Testers are welcome to
593 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
594 cases, but this is not recommended on live sites. (This must be set for
595 MathML to display properly in Mozilla.)
