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 === New installer in 1.17 ===
22 MediaWiki 1.17 is shipping with a completely redesigned installer to fix
23 a lot of outstanding bugs, cleanup the code quality, and make it easier to
24 use. Notably, you can now run upgrades from the web without having to move
25 LocalSettings.php. The specific bugs are listed below in the general notes.
27 === Configuration changes in 1.17 ===
28 * DatabaseFunctions.php that was needed for compatibility with pre-1.3
29 extensions has been removed.
30 * $wgLogAutocreatedAccounts controls whether autocreation of accounts is logged
32 * $wgAllowImageTag can be set to true to whitelist the <img> tag in wikitext.
33 * (bug 12797) Add $wgGalleryOptions for adjusting of default gallery display
35 * $wgAllowUserCssPrefs option allows disabling CSS-based preferences; which can
36 improve page loading speed.
37 * (bug 22858) $wgLocalStylePath is by default set to the same value as
38 $wgStylePath but should never point to a different domain than the site is
39 on, allowing skins to use .htc files which are not cross-domain friendly.
40 * (bug 20193) Added $wgVectorShowVariantName global configuration variable
41 which causes Vector to render the variants drop-down menu with a label
42 showing the current variant name. This is off by default, pending further
43 research into its user experience implications.
44 * XmlFunctions.php has been removed. Use the Xml or Html classes as appropriate.
45 * Added $wgSQLMode for setting database SQL modes - either performance (null)
46 or other reasons (such as enabling stricter checks)
47 * $wgFileStore has been deprecated. The only usage $wgFileStore['deleted'] has
48 been turned into $wgDeletedDirectory.
49 * $wgDeletedDirectory has been added to specify what directory to place deleted
51 * IBM DB2 database no longer uses the db specific $wgDBport_db2 variable but the
53 * The upload link for missing files can now be set separately from the
54 navigation link with $wgUploadMissingFileUrl.
55 * $wgCategoryPrefixedDefaultSortkey was removed and is now always false. This
56 provides more sensible sorting behavior for categories.
57 * Removed unused globals: $wgEnableSerializedMessages, $wgCheckSerialized,
58 $wgUseMemCached, $wgDisableSearchContext, $wgColorErrors,
59 $wgUseZhdaemon, $wgZhdaemonHost and $wgZhdaemonPort.
60 * (bug 24408) The include_path is not modified in the default LocalSettings.php
61 * $wgVectorExtraStyles was removed, and is no longer in use.
62 * $wgLoadScript was added to specify alternative locations for ResourceLoader
64 * $wgResourceLoaderMaxage was added to specify maxage and smaxage times for
65 responses from ResourceLoader based on whether the request's URL contained a
66 version parameter or not.
67 * $wgResourceLoaderDebug was added to specify the default state of debug mode;
68 this will still be overridden with the debug URL parameter a la
70 * $wgResourceLoaderInlinePrivateModules was added to specify whether private
71 modules such as user.options should be embedded in the HTML output or
72 delivered through a resource loader request, which bypasses server cache (like
73 squid) and checks the user parameter against $wgUser. The former adds more
74 data to all pages, while the latter adds a request which cannot be cached
76 * Removed $wgUpdates for database updates; extension should use
77 DatabaseUpdater::addExtensionUpdate().
78 * Removed $wgServerName. It doesn't need to be set anymore and is no longer
79 available as input for other configuration items, either.
80 * Remove $wgRemoteUploads. It was not well supported and superseded by
81 $wgUploadNavigationUrl.

585 MediaWiki 1.17 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
588 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
589 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
594 1.17 has several database changes since 1.16, and will not work without schema
597 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
598 ry, make sure that it is updated as well. Otherwise, errors may arise due to
599 database schema changes.
601 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
602 new database fields are filled with data.
604 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
605 changes are made, and there is a slightly higher chance that things could
606 break. Don't forget to always back up your database before upgrading!
608 See the file UPGRADE for more detailed upgrade instructions.
613 Some output, particularly involving user-supplied inline HTML, may not
614 produce 100% valid or well-formed XHTML output. Testers are welcome to
615 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
616 cases, but this is not recommended on live sites. (This must be set for
617 MathML to display properly in Mozilla.)
619 For notes on 1.16.x and older releases, see HISTORY.
