-== MediaWiki 1.16.5 ==
-
-2011-05-05
-
-This is a security release of the MediaWiki 1.16 branch.
-
-=== Summary of selected changes in 1.16 ===
-
-Selected changes since MediaWiki 1.15 that may be of interest:
-
-* A new skin called Vector was added
-
-* Watchlists now have RSS/Atom feeds. RSS feeds generally are now hidden,
- since Atom is a better protocol and is supported by virtually all clients.
-
-* It's now possible to block users from sending email via Special:Emailuser.
-
-* The maintenance script system was overhauled. Most maintenance scripts now
- have a useful help page when you run them with --help.
-
-* AdminSettings.php is no longer required in order to run maintenance scripts.
- You can just set $wgDBadminuser and $wgDBadminpassword in your
- LocalSettings.php instead.
-
-* The preferences system was overhauled. Preferences are stored in a more
- compact format. Changes to site default preferences will automatically
- affect all users who have not chosen a different preference.
-
-* Support for SQLite was improved. Some broken features were fixed, and it
- now has an efficient full-text search.
-
-* The user groups ACL system was improved by allowing rights to be revoked,
- instead of just granted.
-
-* A new localisation caching system was introduced, which will make MediaWiki
- faster for almost everyone, especially when lots of extensions are enabled.
-
-By default, this new system makes a lot of database queries. If your database
-is particularly slow, or if your system administrator limits your query count,
-or if you want to squeeze as much performance as possible out of Mediawiki,
-set $wgCacheDirectory to a writable path on the local filesystem. Make sure
-you have the DBA extension for PHP installed, this will improve performance
-further.
-
-== Changes since 1.16.4
-
-* (bug 28534) Fixed XSS vulnerability for IE 6 clients. This is the third
- attempt at fixing bug 28235.
-* (bug 28639) Fixed potential privilege escalation when $wgBlockDisablesLogin
- is enabled.
-
-== Changes since 1.16.3 ==
-
-* (bug 28507) The change we made in 1.16.3 to fix bug 28235 (XSS for IE 6
- clients) was not actually sufficient to fix that bug. This release contains
- a second attempt, hopefully we have fixed it this time.
-
-== Changes since 1.16.2 ==
-
-* (bug 28449) Fixed permissions checks in Special:Import which allowed users
- without the 'import' permission to import pages from the configured import
- sources.
-* (bug 28235) Fixed XSS affecting IE 6 and earlier clients only, due to those
- browsers looking for a file extension in the query string of the URL, and
- ignoring the Content-Type header if one is found.
-* (bug 28450) Fixed a CSS validation issue involving escaped comments, which
- led to XSS for Internet Explorer clients and privacy loss for other clients.
-
-== Changes since 1.16.1 ==
-
-* (bug 26642) Fixed incorrect translated namespace due to a regression in the
- language converter.
-* The interface translations were updated.
-* (bug 27093, CVE-2011-0047): Fixed CSS injection vulnerability.
-* (bug 27094) Fixed server-side arbitrary script inclusion vulnerability.
- Affects Windows servers only. A malicious file with extension ".php" must
- exist on the server for the exploit to be effective.
-
-== Changes since 1.16.0 ==
-
-* (bug 24981) Allow extensions to access SpecialUpload variables again
-* (bug 24724) list=allusers was out by 1 (shows total users - 1)
-* (bug 24166) Fixed API error when using rvprop=tags
-* For wikis using French as a content language, Special:Téléchargement works
- again as an alias for Special:Upload.
-* (bug 25167) Correctly load JS fixes for IE6 (fixing a regression in 1.16.0)
-* (bug 25248) Fixed paraminfo errors in certain API modules.
-* The installer now has improved handling for situations where safe_mode is
- active or exec() and similar functions are disabled.
+Security reminder: MediaWiki does not require PHP's register_globals
+setting since version 1.2.0. If you have it on, turn it '''off''' if you can.
+
+== MediaWiki 1.17.0 ==
+
+2011-06-22
+
+This is the first stable release of the MediaWiki 1.17 branch.
+
+=== Summary of selected changes in 1.17 ===
+
+Selected changes since MediaWiki 1.16 that may be of interest:
+
+* A new installer has been introduced. It has a wizard-style interface which is
+ translated into many languages. Many shortcomings in the old installer were
+ addressed with this rewrite. Note that it is no longer required for the config
+ directory to be made writable by the webserver. Instead the generated
+ LocalSettings.php file is offered as a download, which you must then upload
+ to the wiki's base directory.
+
+* ResourceLoader, a new framework for delivering client-side resources such as
+ JavaScript and CSS, has been introduced. These resources are now delivered
+ through the new entry point script "load.php", instead of as static files
+ served directly by the web server. This allows minification, compression and
+ client-side caching to be used more effectively, which should provide a net
+ performance improvement for most users.
+
+* Category sorting has been improved.
+** Sorting is now case insensitive.
+** Sub-categories, pages and files can now be paged separately.
+** When several pages are given the same sort key, they sort by their
+ names instead of randomly.
+
+* The lowest supported version of PHP is now 5.2.3. If necessary, please
+ upgrade PHP prior to upgrading MediaWiki.
+
+=== Changes since 1.17.0rc1 ===
+
+* Fixed syntax error in generated LocalSettings.php when a non-default user
+ rights profile is chosen.
+* (bug 29399) Fixed PostgreSQL installation when the DB user for installation
+ is the same as the one for web access.
+* (bug 29233) Fixed failover for DB slave servers. When a DB slave went down,
+ an error was immediately shown to the user, instead of trying another slave.
+ Was broken since 1.17 beta 1.
+* (bug 29278) Fixed PHP fatal error when attempting to add text to a page via a
+ redirect.
+* (bug 29408) Fixed uploads of files with MIME types that aren't detected by
+ MediaWiki.
+
+=== Changes since 1.17 beta 1 ===
+
+* Fixed warning about missing file "password.js".
+* When installing on MySQL, don't attempt to create a new database user if the
+ same user is used for installation and web access.
+* Fixed SQL query errors in queries with table aliases.
+* (bug 27891) Fixed the "chronology protector", broken since 1.17beta1, which
+ ensures that when database replication is used, the new version is seen by
+ the user immediately after they create or edit an article.
+* (bug 28845) Allow PostgreSQL installation using a non-root user account which
+ has role creation abilities.
+* When installing on PostgreSQL and the install account is the same as the web
+ account, check to make sure that the account has suitable privileges in the
+ mediawiki schema.
+* (bug 28172) Fixed error in PostgreSQL installation when creating the wiki
+ sysop account.
+* Fixed an issue with the Oracle installer in cases where the user is different
+ to the database name.
+* Added "unblockself" to the list of available rights.
+* In the installer, fixed the "user rights profile" option, it never worked.
+* (bug 29117) Fixed Hebrew localisation of the installer.
+* (bug 28840) Reduce the collateral damage caused by the fix for bug 28235 (XSS
+ on Internet Explorer 6 due to a file extension in the query string) by
+ reducing the number of URLs that are blocked, and by redirecting the request
+ to a safer URL where possible instead of blocking it.
+* (bug 28812) Fixed documentation of API action=parse.
+* (bug 28979) Fixed styling of <abbr> and <acronym>.
+* Fixed the error message displayed when you try to create an account by email,
+ but an email address is not given.
+* Fixed JS error due to missing dependency for jquery.suggestions.
+* Exposed $wgExtensionAssetsPath in JavaScript.
+* (bug 28738) Made ResourceLoader support environments with small URL length
+ limits. The length limit can be configured via $wgResourceLoaderMaxQueryLength,
+ and this is set automatically in the generated LocalSettings.php when the
+ php.ini variable "suhosin.get.max_value_length" is set. When a URL exceeds
+ this limit, the request is split up. Also, reduced the average length of
+ load.php URLs by using a more compact parameter format.
+* (bug 25262) Fix for minification of hardcoded data: URIs in CSS.
+* (bug 25124) Respect $wgStyleDirectory in ResourceLoader.
+* Allow installation when no HTTP client is available, don't throw an exception.
+* (bug 27465) Fix metadata extraction for SVG files using unusual namespace
+ names.
+* (bug 29174) Fix regression in upload-by-URL: uploading files larger than the
+ PHP memory limit should work again.
+* Fixed the display of comments in the new user log.
+* (bug 28237) When installing extensions using the web-based installer, create
+ any necessary database tables.
+* (bug 28983) Fixed automated installation of extensions that overwrite $path.
+* Fixed error caused by missing magic words.
+* Fixed breakage of article editing in PostgreSQL due to text search
+ configuration errors.
+* Fixed the HTTPS client used when Curl is not available. This avoids an error
+ during install about failure of the mediawiki-announce subscription.
+* (bug 28162) When installing to PostgreSQL, respect the "database port" input,
+ it was ignored.
+
+=== Configuration changes in 1.17 ===
+
+* $wgLogAutocreatedAccounts controls whether autocreation of accounts is logged
+ to new users log.
+* (bug 22858) $wgLocalStylePath is by default set to the same value as
+ $wgStylePath but should never point to a different domain than the site is
+ on, allowing skins to use .htc files which are not cross-domain friendly.
+* $wgFileStore has been deprecated. The only usage $wgFileStore['deleted'] has
+ been turned into $wgDeletedDirectory.
+* $wgDeletedDirectory has been added to specify what directory to place deleted
+ uploads in.
+* IBM DB2 database no longer uses the db specific $wgDBport_db2 variable but the
+ normal $wgDBport.
+* $wgCategoryPrefixedDefaultSortkey was removed and is now always false. This
+ provides more sensible sorting behavior for categories.
+* Removed unused globals: $wgEnableSerializedMessages, $wgCheckSerialized,
+ $wgUseMemCached, $wgDisableSearchContext, $wgColorErrors, $wgUseZhdaemon,
+ $wgZhdaemonHost and $wgZhdaemonPort.
+* (bug 24408) The include_path is not modified in the default LocalSettings.php
+* $wgVectorExtraStyles was removed, and is no longer in use.
+* Removed $wgUpdates for database updates; extensions should use
+ DatabaseUpdater::addExtensionUpdate() via the LoadExtensionSchemaUpdates hook.
+* Removed $wgServerName. It doesn't need to be set anymore and is no longer
+ available as input for other configuration items, either.
+* It's no longer necessary for LocalSettings.php to include DefaultSettings.php.
+* It's no longer necessary to set $wgCacheEpoch to the file modification time
+ of LocalSettings.php, in LocalSettings.php itself. Instead, this is done
+ automatically if $wgInvalidateCacheOnLocalSettingsChange is true (which is
+ the default).
+* $wgCopyrightIcon is deprecated and $wgFooterIcons['copyright']['copyright']
+ should be used instead.
+* $wgSysopUserBans is deprecated, and will be made permanently true in 1.18.
+ If you need this functionality, you should use the BlockIp hook to filter and
+ reject such blocks.
+* $wgSysopRangeBans is deprecated, you should set $wgBlockCIDRLimit to maximum
+ (32 for IPv4, 128 for IPv6), equivalent to allowing rangeblocks of only 1
+ address at a time.
+

+ User:<name>/common.css and /common.js (if user css/js is enabled).

-* $wgDevelopmentWarnings can be set to true to show warnings about deprecated
- functions and other potential errors when developing.

- mainly a cosmetic change, and does not in any way affect the MessageCache,
- which was already effectively treating the namespace as if it had subpages.
-* Oracle: maintenance/ora/user.sql script for creating DB user on oracle with
- appropriate privileges. Creating this user with web-install page requires
- oci8.privileged_connect set to On in php.ini.

-* Added $wgCacheDirectory, to replace $wgFileCacheDirectory,
- $wgLocalMessageCache, and any other local caches which need a place to put

- it as appropriate.

- signatures. This was always the behaviour documented in DefaultSettings.php
- but has not been the actual behaviour for some time: instead, UTC was used
- by default.
-* Added $wgExtensionAssetsPath, to decouple assets serving from $wgScriptPath.
- If not specified it will default to $wgScriptPath/extensions
-* Added $wgCountTotalSearchHits to make search UI display total number of hits
- with some search engines.
-* Added $wgAdvertisedFeedTypes to decide what feed types (RSS, Atom, both, or
- neither) MediaWiki advertises. Default is array( 'atom' ), so RSS is no
- longer advertised by default (but it still works).
-* Added $wgMemCachedTimeout, controls how long to wait for data from the
- memcached servers.
-* New configuration variables $wgDebugTimestamps and $wgDebugPrintHttpHeaders
- for controlling debug output.

-* Introduced a new system for localisation caching. The system is based around

-* Expanded the number of variables which can be set in the extension messages
- files.
-* Added a feature to allow per-article process pool size control for the parsing
