2
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.

6 == MediaWiki 1.18 ==
7
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
20
21 === PHP 5.2 now required ==
22 In 1.18, the lowest supported version of MediaWiki is now 5.2.x. Please upgrade
23 PHP if you have not done so prior to upgrading MediaWiki.
24
25 === Configuration changes in 1.18 ===
26 * The WantedPages::getSQL hook has been removed and replaced with
27 WantedPages::getQueryInfo . This may break older extensions.
28 * $wgUseCombinedLoginLink controls whether to output a combined
29 login / create account link in the personal bar, or to output separate login
30 and create account links
31 * Skin names are no longer created based on a ucfirst version of the key in
32 $wgValidSkinNames but now the value. This means for
33 $wgValidSkinNames["monobook"] = "MonoBook"; the skin loader will no longer try
34 loading SkinMonobook and will instead load SkinMonoBook.
35 * The parser now attempts to output markers for editsection tokens and defer the
36 rendering of them so skin and language specific markup does not need to be
37 saved inside the parser cache note that this changes the cache key making all
38 old entries in the parser cache invalid you can set $wgUseEditSectionTokens to
39 false to disable this and keep your old parser cache entries.
40 Note that this feature should reduce parser cache fragmentation when enabled.
41 * $wgMaxUploadSize may now be set to an array to specify the upload size limit
42 per upload type.
43 * $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set
44 $wgAPICacheHelpTimeout = 0;
45 * OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed
46 by the page, but $wgAllowUserJs is set to false.
47 * Pure "Skin" class based custom skins are no longer supported, all custom skins
48 should be put together using SkinTemplate and BaseTemplate or QuickTemplate.
49 * The transliteration for passwords in case they were migrated from an old Latin-1
50 install (previous to MediaWiki 1.5) is now only done for wikis with
51 $wgLegacyEncoding set.
52
53 === New features in 1.18 ===
54 * Added a special page, disabled by default, that allows users with the
55 'disableaccount' privilege to permanently deactivate user accounts.
56 * (bug 8130) Query pages should limit to content namespaces, not just main
57 namespace
58 * Search suggestions (other than in the Vector skin) will now use the HTML5
59 datalist feature where supported, currently only Firefox 4.
60 * Special:Contribs now redirects to Special:Contributions
61 * (bug 6672) Images are now autorotated according to their EXIF orientation.
62 This only affects thumbnails; the source remains unrotated.
63 * (bug 25708) Update case mappings and normalization to Unicode 6.0.0
64 * New hook ArticlePrepareTextForEdit added, called when preparing text to be
65 saved.
66 * New parser option PreSaveTransform added, allows the pre-save transformation
67 to be selectively disabled.
68 * Alternative to $wgHooks implemented, using the new Hooks class.
69 * Add width parameter to Special:Filepath to allow getting the file path of a
70 thumbnail.
71 * (bug 26870) Add size to {{filepath:}}

83 MediaWiki:Autoconfirmed.css, etc.
84 * (bug 24230) Uploads of ZIP types, such as MS Office or OpenOffice can now be
85 safely enabled. A ZIP file reader was added which can scan a ZIP file for
86 potentially dangerous Java applets. This allows applets to be blocked
87 specifically, rather than all ZIP files being blocked.
88 * (bug 2429) Allow selection of associated namespace in recent changes
89 * (bug 26217) File size is now checked before uploading in HTML5 browsers

233
234 == Compatibility ==
235
236 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
237 supported.
238
239 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
240 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
241
242
243 == Upgrading ==
244
245 1.18 has several database changes since 1.17, and will not work without schema
246 updates.
247
248 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
249 ry, make sure that it is updated as well. Otherwise, errors may arise due to
250 database schema changes.
251
252 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
253 new database fields are filled with data.
254
255 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
256 changes are made, and there is a slightly higher chance that things could
257 break. Don't forget to always back up your database before upgrading!
258
259 See the file UPGRADE for more detailed upgrade instructions.
260
261
262 === Caveats ===
263
264 Some output, particularly involving user-supplied inline HTML, may not
265 produce 100% valid or well-formed XHTML output. Testers are welcome to
266 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
267 cases, but this is not recommended on live sites. (This must be set for
268 MathML to display properly in Mozilla.)
269
270 For notes on 1.17.x and older releases, see HISTORY.

272
273 === Online documentation ===
274
275 Documentation for both end-users and site administrators is currently being
276 built up on MediaWiki.org, and is covered under the GNU Free Documentation
277 License (except for pages that explicitly state that their contents are in
278 the public domain) :
279
280 http://www.mediawiki.org/wiki/Documentation
281
282
283 === Mailing list ===
284
285 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
286 wikitech-l list:
287
288 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
289
290 A low-traffic announcements-only list is also available:
291
292 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
293
294 It's highly recommended that you sign up for one of these lists if you're
295 going to run a public MediaWiki, so you can be notified of security fixes.
