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 1.14 ===
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 * Editing the MediaWiki namespace is now unconditionally restricted to people
44 with the editinterface right, configuring this in $wgNamespaceProtection
46 * $wgAllowExternalImagesFrom may now be an array of multiple strings.
47 * Introduced $wgEnableImageWhitelist to toggle the on-wiki external image
49 * Added $wgRenderHashAppend to append some string to the parser cache and the
50 sitenotice cache keys.
51 * $wgRCChangedSizeThreshold is now a positive integer by default,
52 * (bug 16006) $wgEnableWriteAPI is now true by default. Authorized can perform
53 write actions using the API.
55 === Migrated extensions ===
56 The following extensions are migrated into MediaWiki 1.14:
58 * Special:DeletedContributions to show deleted user contributions (was extension
60 * Special:Log/newusers recording new users (was extension Newuserlog)
61 * Special:LinkSearch to search for external links (was extension LinkSearch)
64 * Poem (patch by Nathaniel Herman)
67 === New features in 1.14 ===
69 * New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
70 'Special:ListUsers/GROUP/USER', in addition to the older syntax
71 'Special:ListUsers/GROUP' where GROUP is a valid group name.
72 * Configurable per-namespace and per-page notices for the edit form,
73 respectively MediaWiki:Editnotice-# where # is the namespace number, and
74 MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
75 PAGENAME is the page name minus the namespace prefix.
76 * (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
77 search engine indexing on a per-article basis.
78 * Handheld stylesheet options
79 * Added 'DoEditSectionLink' hook as a cleaner unified version of the old
80 'EditSectionLink' and 'EditSectionLinkForOther' hooks. Note that the
81 'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
82 run in all cases instead, so extensions using the old hooks should still work
83 if they ran roughly the same code for both hooks (as is almost certain).
84 * Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
85 $wgCleanSignatures=false
86 * Extensions can use the SkinBuildSidebar hook to modify the content of the
87 sidebar and add custom portlets to it

102 * Unescape more "safe" characters when producing URLs, for added prettiness

151 * api.php now sends "Retry-After" and "X-Database-Lag" HTTP headers if the maxlag
152 check fails, just like index.php does
153 * Added "link" parameter to image links, to allow images to link to an
154 arbitrary title or URL. This should replace inaccessible and incomplete
155 solutions such as CSS-based overlays and ImageMap.

157 using new "alt=" parameter for images
158 * (bug 44) The {{ns:}} core parser function now also accepts localized namespace

167 wiki is set to read-only mode.
168 * Added a call to the 'UnwatchArticleComplete' hook to the watchlist editor. This
169 should make it so that ALL user-accessible methods of removing a page from a watchlist
170 lead to this hook being called (it was previously only called from within Article.php
171 * Maximum execution time for shell processes on linux is now configured with
172 $wgMaxShellTime (180 seconds by default)

373 === Languages updated in 1.14 ===
375 MediaWiki supports over 300 languages. Many localisations are updated
376 regularly. Below only new and removed languages are listed.
378 * Bakhtiari (bqi) (new)
379 * Fiji Hindi (Devanagari script) (hif-deva) (new)
381 * Lezghian (lez) (new)
383 * Eastern Mari (mhr) (new)
386 * Plautdietsch (pdt) (new)
387 * Tarantino (roa-tara) (new)
388 * Serbo-Croatian (sh) (new)
393 MediaWiki 1.14 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
395 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
396 http://bugs.php.net/bug.php?id=34879
397 Upgrade affected systems to PHP 5.1 or higher.
399 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
400 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
405 1.14 has several database changes since 1.13, and will not work without schema
408 If upgrading from before 1.11, and you are using a wiki as a commons repository,
409 make sure that it is updated as well. Otherwise, errors may arise due to
410 database schema changes.
412 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
413 new database fields are filled with data.
415 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
416 changes are made, and there is a slightly higher chance that things could
417 break. Don't forget to always back up your database before upgrading!
419 See the file UPGRADE for more detailed upgrade instructions.
424 Some output, particularly involving user-supplied inline HTML, may not
425 produce 100% valid or well-formed XHTML output. Testers are welcome to
426 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
427 cases, but this is not recommended on live sites. (This must be set for
428 MathML to display properly in Mozilla.)
430 For notes on 1.13.x and older releases, see HISTORY.
