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 1.17 ===
22 * DatabaseFunctions.php that was needed for compatibility with pre-1.3
23 extensions has been removed.
24 * $wgLogAutocreatedAccounts controls whether autocreation of accounts is logged
26 * $wgAllowImageTag can be set to true to whitelist the <img> tag in wikitext.
27 * (bug 12797) Add $wgGalleryOptions for adjusting of default gallery display
29 * $wgAllowUserCssPrefs option allows disabling CSS-based preferences; which can
30 improve page loading speed.
31 * (bug 22858) $wgLocalStylePath is by default set to the same value as
32 $wgStylePath but should never point to a different domain than the site is
33 on, allowing skins to use .htc files which are not cross-domain friendly.
34 * (bug 20193) Added $wgVectorShowVariantName global configuration variable
35 which causes Vector to render the variants drop-down menu with a label
36 showing the current variant name. This is off by default, pending further
37 research into its user experience implications.
38 * Added $wgJQueryVersion, $wgJQueryMinified and $wgJQueryOnEveryPage (true by
39 default) to configure loading of jQuery by MediaWiki.
40 * XmlFunctions.php has been removed. Use the Xml or Html classes as appropriate.
41 * Added $wgSQLMode for setting database SQL modes - either performance (null)
42 or other reasons (such as enabling stricter checks)
43 * $wgFileStore has been deprecated. The only usage $wgFileStore['deleted'] has
44 been turned into $wgDeletedDirectory.
45 * $wgDeletedDirectory has been added to specify what directory to place deleted
47 * IBM DB2 database no longer uses the db specific $wgDBport_db2 variable but the
49 * The upload link for missing files can now be set separately from the
50 navigation link with $wgUploadMissingFileUrl.
51 * $wgCategoryPrefixedDefaultSortkey was removed and is now always false. This
52 provides more sensible sorting behavior for categories.
53 * Removed unused globals: $wgEnableSerializedMessages, $wgCheckSerialized,
54 $wgUseMemCached, $wgDisableSearchContext, $wgColorErrors,
55 $wgUseZhdaemon, $wgZhdaemonHost and $wgZhdaemonPort.
56 * (bug 24408) The include_path is not modified in the default LocalSettings.php
57 * $wgVectorExtraStyles was removed, and is no longer in use.
58 * $wgLoadScript was added to specify alternative locations for ResourceLoader
60 * $wgResourceLoaderMaxage was added to specify maxage and smaxage times for
61 responses from ResourceLoader based on whether the request's URL contained a
62 version parameter or not.
63 * $wgResourceLoaderDebug was added to specify the default state of debug mode;
64 this will still be overridden with the debug URL parameter a la
66 * $wgResourceLoaderInlinePrivateModules was added to specify whether private
67 modules such as user.options should be embedded in the HTML output or
68 delivered through a resource loader request, which bypasses server cache (like
69 squid) and checks the user parameter against $wgUser. The former adds more
70 data to all pages, while the latter adds a request which cannot be cached
72 * Removed $wgUpdates for database updates; extension should use
73 DatabaseUpdater::addExtensionUpdate().
74 * Removed $wgServerName. It doesn't need to be set anymore and is no longer
75 available as input for other configuration items, either.
76 * Remove $wgRemoteUploads. It was not well supported and superseded by
77 $wgUploadNavigationUrl.
78 * $wgUpgradeKey allows unlocking the web installer for upgrades without having
79 to move LocalSettings.php
80 * The FailFunction "error handling" method has now been removed
81 * $wgAdditionalMailParams added to allow setting extra options to mail() calls.

420 one of the backlinks generators with limit=max.
421 * (bug 24656) API's parse module needs option to disable PP report
422 * PARAM_REQUIRED parameter flag added. If this flag is set, and the end user
423 does not set the parameter, the API will automatically throw an error.
424 * (bug 24665) When starttimestamp is not specified, fake it by setting it to
425 NOW, not to the timestamp of the last edit
426 * (bug 24677) axto= parameters added to allcategories, allimages, alllinks,
427 allmessages, allpages, and allusers

435 * For required string parameters, if '' is provided, this is now classed as

438 * (bug 24166) API error when using rvprop=tags
439 * Introduced "asynchronous download" mode for upload-by-url. Requires
440 $wgAllowAsyncCopyUploads to be true.

442 implicit groups rather than showing 0.
443 * (bug 25248) API: paraminfo errors with certain modules
444 * (bug 25303) Fix API parameter integer validation to actually enforce validation
445 on the input values in addition to giving a warning. Also add flag to enforce (die)
446 if integer out of range (breaking change!)
447 * (bug 24792) API help for action=purge sometimes wrongly stated whether a
448 POST request was needed due to cache pollution
449 * Added iiprop=parsedcomment to prop=imageinfo, similar to prop=revisions
450 * Added rvparse to parse revisions. For performance reasons if this option is
451 used, rvlimit is enforced to 1.
452 * If a action=parse request provides an oldid that is actually the current revision
453 id, try the parser cache, and save it to it if necessary
454 * (bug 25463) Export header should not be shown if no pages were requested, to

485 MediaWiki 1.17 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
488 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
489 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
494 1.17 has several database changes since 1.16, and will not work without schema
497 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
498 ry, make sure that it is updated as well. Otherwise, errors may arise due to
499 database schema changes.
501 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
502 new database fields are filled with data.
504 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
505 changes are made, and there is a slightly higher chance that things could
506 break. Don't forget to always back up your database before upgrading!
508 See the file UPGRADE for more detailed upgrade instructions.
513 Some output, particularly involving user-supplied inline HTML, may not
514 produce 100% valid or well-formed XHTML output. Testers are welcome to
515 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
516 cases, but this is not recommended on live sites. (This must be set for
517 MathML to display properly in Mozilla.)
