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

21 === Configuration changes in 1.18 ===
22 * The WantedPages::getSQL hook has been removed and replaced with
23 WantedPages::getQueryInfo . This may break older extensions.
24 * $wgUseCombinedLoginLink controls whether to output a combined login / create account
25 link in the personal bar, or to output separate login and create account links
26 * Skin names are no longer created based on a ucfirst version of the key in $wgValidSkinNames but now
27 the value. This means for $wgValidSkinNames["monobook"] = "MonoBook"; the skin
28 loader will no longer try loading SkinMonobook and will instead load SkinMonoBook.
29 * The parser now attempts to output markers for editsection tokens and defer the rendering
30 of them so skin and language specific markup does not need to be saved inside the parser cache
31 note that this changes the cache key making all old entries in the parser cache invalid you
32 can set $wgUseEditSectionTokens to false to disable this and keep your old parser cache entries.
33 Note that this feature should reduce parser cache fragmentation when enabled.
34
35 === New features in 1.18 ===
36 * Added a special page, disabled by default, that allows users with the
37 'disableaccount' privilege to permanently deactivate user accounts.
38 * (bug 8130) Query pages should limit to content namespaces, not just main namespace
39 * Search suggestions (other than in the Vector skin) will now use the HTML5
40 datalist feature where supported, currently only Firefox 4.
41

78 === Languages updated in 1.18 ===
79
80 MediaWiki supports over 330 languages. Many localisations are updated
81 regularly. Below only new and removed languages are listed, as well as
82 changes to languages because of Bugzilla reports.
83
84 == Compatibility ==
85
86 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
87 supported.
88
89 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
90 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
91
92
93 == Upgrading ==
94
95 1.18 has several database changes since 1.17, and will not work without schema
96 updates.
97
98 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
99 ry, make sure that it is updated as well. Otherwise, errors may arise due to
100 database schema changes.
101
102 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
103 new database fields are filled with data.
104
105 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
106 changes are made, and there is a slightly higher chance that things could
107 break. Don't forget to always back up your database before upgrading!
108
109 See the file UPGRADE for more detailed upgrade instructions.
110
111
112 === Caveats ===
113
114 Some output, particularly involving user-supplied inline HTML, may not
115 produce 100% valid or well-formed XHTML output. Testers are welcome to
116 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
117 cases, but this is not recommended on live sites. (This must be set for
118 MathML to display properly in Mozilla.)
119
120 For notes on 1.17.x and older releases, see HISTORY.
121
122
123 === Online documentation ===
124
125 Documentation for both end-users and site administrators is currently being
126 built up on MediaWiki.org, and is covered under the GNU Free Documentation
127 License (except for pages that explicitly state that their contents are in
128 the public domain) :

131
132
133 === Mailing list ===
134
135 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
136 wikitech-l list:
137
138 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
139
140 A low-traffic announcements-only list is also available:
141
142 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
143
144 It's highly recommended that you sign up for one of these lists if you're
145 going to run a public MediaWiki, so you can be notified of security fixes.

148 === IRC help ===
