-== MediaWiki 1.16.0 ==
-
-2010-07-28
-
-This is a stable 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:
-
-* 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 beta 3 ==
-
-* (bug 23769) Disabled HTML 5 client-side form validation. Was introduced in 
-  1.16 beta 1, but is currently poorly supported by browsers.
-* (bug 23175) Re-added window.ta variable for backwards compatibility.
-* (bug 23264) Fixed breakage of various command line scripts due to extra line
-  endings being inserted by Maintenance::output().
-* Fixed HTTP client functionality with safe_mode=On.
-* Fixed parser tests broken in 1.16 beta 3.
-* For Oracle DB backend: fixed parser tests and table prefix feature.
-* (bug 23767) Fixed PHP warning when REQUEST_URI is blank (IIS issue).
-* Fixed plural function for Northern Sami (se)
-* (bug 23597) Fixed conflicts between ID attributes in the Vector skin and

-* (bug 23465) Don't ignore the predefined destination filename on 
-  Special:Upload after following a red link to a file.
-* In SQLite full-text search feature: fixed "move page" feature, was non-
-  functional.
-* (bug 24565) Fixed Cache-Control headers sent from API modules, to protect
-  user privacy in the case where an attacker can access the wiki through the
-  same HTTP proxy as a logged-in user.
-* Fixed an XSS vulnerability in profileinfo.php for installations with 
-  $wgEnableProfileInfo = true (false by default)
-* Fixed a case where an X-Vary-Options header was sent despite $wgUseXVO being
-  false. Fixed a minor header parsing issue when $wgUseXVO = true.
-* Fixed a register_globals arbitrary inclusion vulnerability in 
-  MediaWikiParserTest.php, introduced in 1.16 beta 1.
-
-== Changes since 1.16 beta 2 ==
-
-* Fixed bugs in the [[Special:Userlogin]] and [[Special:Emailuser]] handling of
-  invalid usernames.
-* Fixed sorting in [[Special:Allmessages]]
-* (bug 23113) Fixed title in the show/hide links on diff pages

-  in page views and previews when the language converter is enabled.
-* (bug 23148) Fixed a local path disclosure vulnerability in ImageMagick image
-  scaling, which was introduced in 1.16 beta 1. 
-* Improved error checking on installer.
-* (bug 22970) Fixed a JavaScript error in the upload destination conflict 
-  check.
-* (bug 23167) Check the watch checkbox by default if the watchcreations 
-  preference is set.
-* (bug 23171) Improve IE6 version check to avoid false positives.
-* (bug 23176) Fixed upload warning override feature "upload new version", 
-  broken in 1.16 beta 1.
-* Fixed regression in unwatch links sent out in notification emails. When the 
-  mailing job was deferred via the job queue, the title was incorrect.
-* (bug 23534) Fixed SQL query error in API list=allusers.
-* Fixed a bug in uploads for non-JavaScript clients. An empty string was used
-  as the default destination filename, instead of the source filename as

-* (bug 23371) Fixed CSRF vulnerability in "e-mail me my password", "create 
-  account" and "create by e-mail" features of [[Special:Userlogin]]
-* (bug 23687) Fixed XSS vulnerability affecting IE clients only, due to a CSS 
-  validation issue.
-* Fixed a DoS vulnerability in ImageMagick image scaling. ImageMagick 
-  expanded wildcard characters "?" and "*" in image filenames, potentially 
-  causing large numbers of images to be scaled in response to a single request.
-  The fix for this involves breaking the scaling of such image filenames until
-  ImageMagick 6.6.1-5 or later is deployed, see bug 23361 for more details.
-* (bug 23608) Fixed invalid HTML in diff pages.
-
-=== Changes since 1.16 beta 1 ===
-
-* Fixed errors in maintenance/patchSql.php
-* (bug 19627) Fix regression from r57867 where HTMLForm would output 
-  <element classes="foo bar"> rather than <element class="foo bar">
-* Fixed broken "-r" option to maintenance/lag.php
-* (bug 23076) Fixed login CSRF vulnerability. Logins now require a token to 
-  be submitted along with the user name and password.
-
-=== Configuration changes in 1.16 ===
-
-* (bug 18222) $wgMinimalPasswordLength default is now 1
-* $wgSessionHandler can be used to configure session.save_handler
-* $wgLocalFileRepo/$wgForeignFileRepos now have a 'fileMode' parameter to
-  be used when uploading/moving files
-* (bug 18761) $wgHiddenPrefs is a new array for specifying preferences not
-  to be shown to users
-* $wgAllowRealName and $wgAllowUserSkin were deprecated in favor of
-  $wgHiddenPrefs[] = 'realname', but the former are still retained
-  for backwards-compatibility
-* (bug 9257) $wgRCMaxAge now defaults to three months
-* $wgDevelopmentWarnings can be set to true to show warnings about deprecated
-  functions and other potential errors when developing.
-* Subpages are now enabled in the MediaWiki namespace by default.  This is
-  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.
-* Removed UserrightsChangeableGroups hook introduced in 1.14
-* Added $wgCacheDirectory, to replace $wgFileCacheDirectory,
-  $wgLocalMessageCache, and any other local caches which need a place to put
-  files.
-* $wgFileCacheDirectory is no longer set to anything by default, and so either
-  needs to be set explicitly, or $wgCacheDirectory needs to be set instead.
-* $wgLocalMessageCache has been removed. Instead, set $wgUseLocalMessageCache
-  to true
-* Removed $wgEnableSerializedMessages and $wgCheckSerialized. Similar
-  functionality is now available via $wgLocalisationCacheConf.
-* $wgMessageCache->addMessages() is deprecated. Messages added via this
-  interface will not appear in Special:AllMessages.
-* $wgRegisterInternalExternals can be used to record external links pointing
-  to same server
-* (bug 19907) $wgCrossSiteAJAXdomains and $wgCrossSiteAJAXdomainExceptions added
-  to control which external domains may access the API via cross-site AJAX.
-* $wgMaintenanceScripts for extensions to add their scripts to the default list
-* $wgMemoryLimit has been added, default value '50M'
-* $wgExtraRandompageSQL is deprecated, the SpecialRandomGetRandomTitle hook
-  should be used instead
-* (bug 20489) $wgIllegalFileChars added to override the default list of illegal
-  characters in file names.
-* (bug 19646) $wgImgAuthDetails added  to display reason access to uploaded file
-  was denied to users(img_auth only)
-* (bug 19646) $wgImgAuthPublicTest added to test to see if img_auth set up
-  correctly (img_auth only)
-* $wgUploadMaintenance added to disable file deletions and restorations during
-  maintenance
-* $wgCapitalLinkOverrides added to configure per-namespace capitalization
-* (bug 21172) $wgSorbsUrl can now be an array with multiple DNSBL and renamed
-  to $wgDnsBlacklistUrls (backward compatibility kept)
-* $wgEnableHtmlDiff has been removed
-* (bug 3340) $wgBlockCIDRLimit added (default: 16) to configure the low end of
-  CIDR ranges for blocking
-* $wgUseInstantCommons added for quick and easy enabling of Commons as a remote
-  file repository
-* $wgDBAhandler added to choose a DBA handler when using CACHE_DBA
-* $wgPreviewOnOpenNamespaces for extensions that create namespaces that behave
-  similarly to the category namespace.
-* $wgEnableSorbs renamed to $wgDnsBlacklistUrls ($wgEnableSorbs kept for
-  backward compatibility)
-* $wgUploadNavigationUrl now also affects images inline images that do not
-  exist. In that case the URL will get (?|&)wpDestFile=<filename> appended to
-  it as appropriate.
-* If $wgLocaltimezone is null, use the server's timezone as the default for
-  signatures. This was always the behaviour documented in DefaultSettings.php
-  but has not been the actual behaviour for some time: instead, UTC was used
+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 1.17.4 ==
+2012-04-25
+
+This a maintenance 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 1.17.3 ===
+
+* (bug 35961) Hash comparison should always be strict.
+* Fix broken email confirmation expiration caused by MWCryptRand changes.
+* (bug 35671) PHP Notice: Undefined index: gettoken in includes/api/ApiMain.php
+  on line 598.
+
+=== Changes since 1.17.2 ===
+
+* (bug 22555) Remove or skip strip markers from tag hooks like &lt;nowiki&gt; in
+  core parser functions which operate on strings, such as padleft.
+* (bug 34212) ApiBlock/ApiUnblock allow action to take place without a token
+  parameter present.
+* (bug 34907) Fixed exposure of tokens through load.php that could have facilitated
+  CSRF attacks.
+* (bug 35317) CSRF in Special:Upload.
+
+=== Changes since 1.17.1 ===
+* (bug 33117) prop=revisions allows deleted text to be exposed through cache pollution.
+* (bug 32709) Private Wiki users were always taken to Special:Badtitle on login.
+
+=== Changes since 1.17.0 ===
+
+* (bug 29535) Added missing Creative Commons CC0 icon.
+* (bug 29726) Fixed failure to load internationalization messages in 
+  client-side scripts on WebKit-based browsers.
+* Fixed a bug in message transformation where the previous language could leak 
+  into later transformations in the UI language.
+* (bug 29091) Fixed form of native name for Ossetic language (Иронау -> Ирон)
+* Fixed maintenance scripts upgrade1_5.php and rebuildImages.php, they did not
+  work at all since 1.17 beta 1.
+* (bug 29531) Fixed img_auth.php for thumbnails and other filenames with 
+  multiple dots, was broken by the fix for bug 28840.
+* In the maintenance script purgeList.php, fixed a fatal error when a page 
+  title is given, instead of a URL.
+* (bug 19514) Unordered list list-style-image should be IE6-compatible (8-bit).
+* Installer checked for magic_quotes_runtime instead of register_globals.
+* $wgSVGMaxSize is now applied to the smaller of width or height, making very
+  wide pano/timeline/diagram SVGs renderable at saner sizes.
+* (bug 29959) Installer fatal when cURL and allow_url_fopen is disabled and user
+  tries to subsribe to mediawiki-announce.
+* Installer checked for magic_quotes_runtime instead of register_globals
+* (bug 30131) XCache with variable caching disabled no longer used for variable
+  caching (CACHE_ACCEL)
+* (bug 30264) Changed installer-generated LocalSettings.php to use require_once()
+  instead require() for included extensions.
+* (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP
+  warnings/notices to be thrown
+* (bug 30907) Special:Unusedcategories should sort ascendingly.
+* (bug 30219) The page shown when LocalSettings.php does not exist was broken on
+  Windows servers.
+* Hardcoded NLS_NUMERIC_CHARACTERS for Oracle DB to prevent type conversion errors.
+* Fixed recentchanges FK violation on page delete and cache purge error in updater
+  for Oracle DB.
+* (bug 32276) Skins were generating output using the internal page title which
+  would allow anonymous users to determine wheter a page exists, potentially
+  leaking private data. In fact, the curid and oldid request parameters would
+  allow page titles to be enumerated even when they are not guessable.
+* (bug 32616) action=ajax requests were dispatched to the relevant internal
+  functions without any read permission checks being done. This could lead to
+  data leakage on private wikis.
+
+=== 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.
+* Removed DEFAULT '' NOT NULL field definitions from Oracle DB schema because 
+  using the DEFAULT value ('') in DML broke Oracle backend as it treats an 
+  empty VARCHAR2 value as NULL. Indexes on Oracle do not require NOT NULL
+  fields.
+
+=== 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.
+
+=== New features in 1.17 ===
+
+* (bug 10183) Users can now add personal styles and scripts to all skins via
+  User:<name>/common.css and /common.js (if user css/js is enabled).
+* (bug 22748) Add anchors on Special:ListGroupRights.
+* (bug 21981) Add parameter 'showfilename' to <gallery> to automatically
+  apply the names of the individual files within the gallery.

+* (bug 4597) Provide support in Special:Contributions to show only "current"
+  contributions
+* (bug 17857) {{anchorencode}} acts more like how the parser creates section ids
+* (bug 21477) \& can now be used in <math>
