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.
52 === Migrated extensions ===
53 The following extensions are migrated into MediaWiki 1.14:
55 * DismissableSiteNotice to allow registered users to dismiss the site notice
56 * Special:DeletedContributions to show deleted user contributions (was extension
58 * Special:Log/newusers recording new users (was extension Newuserlog)
59 * Special:LinkSearch to search for external links (was extension LinkSearch)
62 * Special:Nuke to mass delete all pages created by a user
63 * Poem (patch by Nathaniel Herman)
65 === New features in 1.14 ===
67 * New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
68 'Special:ListUsers/GROUP/USER', in addition to the older syntax
69 'Special:ListUsers/GROUP' where GROUP is a valid group name.
70 * Configurable per-namespace and per-page notices for the edit form,
71 respectively MediaWiki:Editnotice-# where # is the namespace number, and
72 MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
73 PAGENAME is the page name minus the namespace prefix.
74 * (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
75 search engine indexing on a per-article basis.
76 * Handheld stylesheet options
77 * Added 'DoEditSectionLink' hook as a cleaner unified version of the old
78 'EditSectionLink' and 'EditSectionLinkForOther' hooks. Note that the
79 'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
80 run in all cases instead, so extensions using the old hooks should still work
81 if they ran roughly the same code for both hooks (as is almost certain).
82 * Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
83 $wgCleanSignatures=false
84 * Extensions can use the SkinBuildSidebar hook to modify the content of the
85 sidebar and add custom portlets to it

96 added 'convertlink=no|yes' on GET requests whether have the link titles
97 being converted or not
98 * (bug 14921) Special:Contributions/: add user name to <title>
100 * Unescape more "safe" characters when producing URLs, for added prettiness
101 * Introduced a new hook 'SkinAfterContent' that allows extensions to add text

149 * api.php now sends "Retry-After" and "X-Database-Lag" HTTP headers if the maxlag

151 * Configurable per-namespace and per-page header, respectively
152 MediaWiki:Pageheader-# where # is the namespace number, and
153 MediaWiki:Pagenumber-#-PAGENAME where # is the page's namespace number and
154 PAGENAME is the page name minus the namespace prefix. Can be disabled with
155 the new magic word __NOHEADER__
156 * Added "click" parameter to image links, to allow images to link to an
157 arbitrary title or URL. This should replace inaccessible and incomplete

316 regularly. Below only new and removed languages are listed.
318 * Bakhtiari (bqi) (new)
319 * Fiji Hindi (Devanagari script) (hif-deva) (new)
321 * Lezghian (lez) (new)

326 * Tarantino (roa-tara) (new)
327 * Serbo-Croatian (sh) (new)
332 MediaWiki 1.14 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
334 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
335 http://bugs.php.net/bug.php?id=34879
336 Upgrade affected systems to PHP 5.1 or higher.
338 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
339 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
344 1.14 has several database changes since 1.13, and will not work without schema
347 If upgrading from before 1.11, and you are using a wiki as a commons repository,
348 make sure that it is updated as well. Otherwise, errors may arise due to
349 database schema changes.
351 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
352 new database fields are filled with data.
354 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
355 changes are made, and there is a slightly higher chance that things could
356 break. Don't forget to always back up your database before upgrading!
358 See the file UPGRADE for more detailed upgrade instructions.
363 Some output, particularly involving user-supplied inline HTML, may not
364 produce 100% valid or well-formed XHTML output. Testers are welcome to
365 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
366 cases, but this is not recommended on live sites. (This must be set for
367 MathML to display properly in Mozilla.)
369 For notes on 1.13.x and older releases, see HISTORY.
