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 1.14 ===
22
23 * $wgExemptFromUserRobotsControl is an array of namespaces to be exempt from
24 the effect of the new __INDEX__/__NOINDEX__ magic words. (Default: null, ex-
25 empt all content namespaces.)
26 * $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4
27 has been $wgSearchForwardUrl.
28 * (bug 15080) $wgOverrideSiteFeed has been added. Setting either
29 $wgSiteFeed['rss'] or 'atom' to a URL will override the default Recent Changes
30 feed that appears on all pages.
31 * $wgSQLiteDataDirMode has been introduced as the default directory mode for
32 SQLite data directories on creation. Note this setting is separate from
33 $wgDirectoryMode, which applies to all normal directories created by MediaWiki.
34 * $wgGroupsAddToSelf and $wgGroupsRemoveFromSelf now work more like
35 $wgAddGroups and $wgRemoveGroups, where the user must belong to a specified
36 group in order to add or remove those groups from themselves.
37 Backwards compatibility is maintained.
38 * $wgRestrictDisplayTitle controls if the use of the {{DISPLAYTITLE}} magic
39 word is restricted to titles equivalent to the actual page title. This
40 is true per default, but can be set to false to allow any title.
41 * $wgSpamRegex may now be an array of multiple regular expressions.
42 * $wgAjaxSearch has been removed; use $wgEnableMWSuggest instead.
43
44 === New features in 1.14 ===
45
46 * New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
47 'Special:ListUsers/GROUP/USER', in addition to the older syntax
48 'Special:ListUsers/GROUP' where GROUP is a valid group name.
49 * Configurable per-namespace and per-page notices for the edit form,
50 respectively MediaWiki:Editnotice-# where # is the namespace number, and
51 MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
52 PAGENAME is the page name minus the namespace prefix.
53 * (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
54 search engine indexing on a per-article basis.
55 * Handheld stylesheet options
56 * Added 'DoEditSectionLink' hook as a cleaner unified version of the old
57 'EditSectionLink' and 'EditSectionLinkForOther' hooks. Note that the
58 'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
59 run in all cases instead, so extensions using the old hooks should still work
60 if they ran roughly the same code for both hooks (as is almost certain).
61 * Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
62 $wgCleanSignatures=false
63 * Extensions can use the SkinBuildSidebar hook to modify the content of the
64 sidebar and add custom portlets to it
65 * Added 'MakeGlobalVariablesScript' hook for extensions to be able to add vari-
66 ables into into the output of Skin::makeVariablesScript
67 * (bug 13846) Added $wgAddGroups and $wgRemoveGroups display on
68 Special:ListGroupRights
69 * (bug 14377) Add a date selector to history pages
70 * (bug 15007) New 'pagetitle-view-mainpage' message allows the HTML <title> of
71 the main page to be customized
72 * Added $wgDisableTitleConversion to disabling the conversion for all pages on
73 the wiki
74 * Added 'noconvertlink' toggle that can be set per user preferences, also
75 added 'convertlink=no|yes' on GET requests whether have the link titles
76 being converted or not
77 * (bug 14921) Special:Contributions/: add user name to <title>
78 Patch by Emufarmers
79 * Unescape more "safe" characters when producing URLs, for added prettiness
80 * Introduced a new hook 'SkinAfterContent' that allows extensions to add text
81 after the page content and article metadata. Updated all skins and skin
82 templates to work with that hook.
83 * (bug 14929) removeUnusedAccounts.php now supports 'ignore-touched' and
84 'ignore-groups'. Patch by Louperivois
85 * (bug 15127) Work around minor display glitch in Opera.
86 * By default, reject file uploads that look like ZIP files, to avoid the
87 so-called GIFAR vulnerability.
88 * (bug 15141) Give ability to only list protected pages with the cascading
89 option enabled on Special:ProtectedPages
90 * (bug 15157) Special:Watchlist has the same options as Special:Watchlist:
91 Show/Hide logged in users, Show/Hide anonymous, Invert namespace selection
92 * Added hook 'UserrightsChangeableGroups' to allow modification of what
93 groups may be added or removed via the Special:UserRights interface.
94 * HTML entities like &nbsp; now work (are not escaped) in edit summaries.
95 * (bug 13815) In the comment for page moves, use the colon-separator message
96 instead of a hardcoded colon.
97 * Allow <gallery> to accept image names without an Image: prefix
98 * Add tooltips to rollback and undo links
99 * Backend upload code has been removed from SpecialUpload.php. This may cause
100 backwards incompatibility with upload extensions.
101 * BMP images are now displayed as PNG
102 * (bug 13471) Added NUMBERINGROUP magic word
103 * (bug 11884) Now support Flash EXIF attribute
104

129 * (bug 14868) Setting $wgFeedDiffCutoff to 0 now disables generation of the diff

132 allows having the unprefixed page title as the default category sortkey

169 shown as empty instead of the current time.
170 * API search now falls back to fulltext search by default when using Lucene

188 etc. (AKA lists) instead of arrays with pageIDs as keys (AKA hash tables)
189 for consistency with other list modules.
190 * Added action=watch
191 * (bug 15275) apprefix and related parameters ignore spaces at the end
192 * action=edit no longer throws unknown error 228 when trying to create an empty

196
197 === Languages updated in 1.14 ===
198
199 MediaWiki supports over 300 languages. Many localisations are updated
200 regularly. Below only new and removed languages are listed.
201
202 (no changes yet)
203
204 == Compatibility ==
205
206 MediaWiki 1.14 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
207
208 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
209 http://bugs.php.net/bug.php?id=34879
210 Upgrade affected systems to PHP 5.1 or higher.
211
212 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
213 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
214
215
216 == Upgrading ==
217
218 If upgrading from before 1.11, and you are using a wiki as a commons repository,
219 make sure that it is updated as well. Otherwise, errors may arise due to
220 database schema changes.
221
222 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
223 new database fields are filled with data.
224
225 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
226 changes are made, and there is a slightly higher chance that things could
227 break. Don't forget to always back up your database before upgrading!
228
229 See the file UPGRADE for more detailed upgrade instructions.
230
231
232 === Caveats ===
233
234 Some output, particularly involving user-supplied inline HTML, may not
235 produce 100% valid or well-formed XHTML output. Testers are welcome to
236 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
237 cases, but this is not recommended on live sites. (This must be set for
238 MathML to display properly in Mozilla.)
239
240 For notes on 1.13.x and older releases, see HISTORY.
241
242
243 === Online documentation ===
244
245 Documentation for both end-users and site administrators is currently being
246 built up on MediaWiki.org, and is covered under the GNU Free Documentation
247 License (except for pages that explicitly state that their contents are in
248 the public domain) :
249
250 http://www.mediawiki.org/wiki/Documentation
251
252
253 === Mailing list ===
254
255 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
256 wikitech-l list:
257
258 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
259
260 A low-traffic announcements-only list is also available:
261
262 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
263
264 It's highly recommended that you sign up for one of these lists if you're
265 going to run a public MediaWiki, so you can be notified of security fixes.
266
267
268 === IRC help ===
269
270 There's usually someone online in #mediawiki on irc.freenode.net
