+  can rotate the image thumbnail appropriately. Metadata support has been generally
+  improved, and can now extract IPTC and XMP metadata.

+  RTL users.

+  from watchlist.
+* (bug 32183) remove the client-* classes added from user-agent-sniffing onto
+  the <html> element.
+* (bug 29912) Unit tests break if parsertest tables are still present.
+* (bug 31694) During installation, tabbing order (cursor focus) goes to logo
+  instead of 'continue'.
+* (bug 29102) Upgrade fails "Unknown character set: 'mysql4".
+* (bug 31990) justify paragraphs pref adds extra space to category listing.

+* (bug 31822) Error during upgrade due to output buffer reset in stdout.
+
+=== Configuration changes in 1.18 ===
+* The WantedPages::getSQL hook has been removed and replaced with
+  WantedPages::getQueryInfo. This may break older extensions.
+* The SkinTemplateBuildContentActionUrlsAfterSpecialPage,
+  SkinTemplateContentActions and SkinTemplateTabs hooks have been removed in
+  favor of SkinTemplateNavigation and SkinTemplateNavigation::SpecialPage.
+* $wgUseCombinedLoginLink controls whether to output a combined
+  login / create account link in the personal bar, or to output separate login
+  and create account links.
+* Skin names are no longer created based on a ucfirst version of the key in
+  $wgValidSkinNames but now the value. This means for
+  $wgValidSkinNames["monobook"] = "MonoBook"; the skin loader will no longer try
+  loading SkinMonobook and will instead load SkinMonoBook.
+* $wgMaxUploadSize may now be set to an array to specify the upload size limit
+  per upload type.
+* $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set
+  $wgAPICacheHelpTimeout = 0;
+* OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed
+  by the page, but $wgAllowUserJs is set to false.
+* Pure "Skin" class based custom skins are no longer supported, all custom skins
+  should be put together using SkinTemplate and BaseTemplate or QuickTemplate.
+* The transliteration for passwords in case they were migrated from an old
+  Latin-1 install (previous to MediaWiki 1.5) is now only done for wikis with
+  $wgLegacyEncoding set.
+* (bug 27508) Add $wgSVGMetadataCutoff to limit the maximum amount of an SVG we
+  look at when finding metadata to prevent excessive resource usage.
+* $wgSysopUserBans and $wgSysopRangeBans (deprecated in 1.17) are now removed.
+  Use $wgBlockCIDRLimit = array( 'IPv4' => 43, 'IPv6' => 128 ) to achieve the
+  same functionality as $wgSysopRangeBans; you can use the BlockIp hook to
+  replicate $wgSysopUserBans functionality.
+* The options on the block form have been standardised such that checking a box
+  makes the block 'more serious'; so while "check to prevent account creation"
+  and "check to enable autoblock" remain the same, "check to allow user-talk
+  edit" is reversed to "check to *disable* user-talk edit", and "check to block
+  anon-only" becomes "check to block logged-in users too".  The default settings
+  remain the same.
+* Most of the field names on the Special:Block form have been changed, which
+  will probably break screen-scraping bots.
+* (bug 26866) The 'trackback' right is no longer granted to sysops by default.
+  $wgUseTrackbacks is already false by default.
+* (bug 17009) the hiddenStructure CSS class, a highly hackish way of at least
+  *appearing* to hide article elements, has been removed.  Use the
+  ParserFunctions extension to actually remove unwanted elements from the
+  output.
+* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable
+  math conversion after upgrading, obtain the Math extension from SVN or from
+  http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php:
+  require_once "$IP/extensions/Math/Math.php";
+* $wgProfiler is now a configuration array, see StartProfiler.sample for
+  details.
+* $wgProfiling has been removed.
+* The spyc library is now no longer included in phase3.
+* (bug 28343) Unused preferences contextlines/contextchars have been removed
+* $wgSkinExtensionFunctions has been removed. Use $wgExtensionFunctions instead.
+* $wgProto has been removed. You now only need to set $wgServer to change the
+  URL protocol.
+* $wgRateLimitsExcludedGroups (deprecated in 1.13) has been removed.
+* $wgInputEncoding and $wgOutputEncoding (deprecated in 1.5) have now been removed.
+* $wgAllowUserSkin (deprecated in 1.16) has now been removed.
+* $wgExtraRandompageSQL (deprecated in 1.16) has now been removed.
+* LogReader and LogViewer classes (deprecated in 1.14) have now been removed.
+* (bug 26033) Added $wgArticleCountMethod to select the method to use to say
+  whether a page is an article or not. $wgUseCommaCount is now deprecated.
+* $wgEnableDublinCoreRdf and $wgEnableCreativeCommonsRdf no longer work in core,
+  and the functionality has been moved to the relevant extensions. See
+  http://www.mediawiki.org/wiki/Extension:DublinCoreRdf and
+  http://www.mediawiki.org/wiki/Extension:CreativeCommonsRdf as appropriate.
+* (bug 21107) Split error "customcssjsprotected" into separate messages for JS and CSS
+* Removed $wgCheckCopyrightUpload from DefaultSettings, since the relevant feature
+  was removed in about 1.5.
+* LogPageValidTypes, LogPageLogName, LogPageLogHeader and LogPageActionText
+  hooks have been removed.
+* New hook "Collation::factory" to allow extensions to create custom
+  category collations.
+* $wgGroupPermissions now supports per namespace permissions.
+* $wgEnableAutoRotation enables or disables auto-rotation. Leaving it set to
+  null will cause MediaWiki to determine if auto-rotation is available.
+
+=== New features in 1.18 ===
+* BREAKING CHANGE: action=watch / action=unwatch now requires a token.
+* BREAKING CHANGE: Article class hierarchy split into WikiPage (backend).
+  and Article (frontend) hierarchies. Several hooks now pass a WikiPage object instead
+  of an Article object. These hooks all use an $article paramater as documented in hooks.txt.
+  Extensions should be updated to account for this, though most won't require any changes.
+* (bug 27860) Minor edit after clicking 'new section' tab
+  Now the "This is a minor edit" checkbox is not available when you
+  create a page or new section.
+* (bug 8130) Query pages should limit to content namespaces, not just main
+  namespace.
+* Special:Contribs now redirects to Special:Contributions.
+* (bug 6672) Images are now autorotated according to their EXIF orientation.
+  This only affects thumbnails; the source remains unrotated.
+* (bug 25708) Update case mappings and normalization to Unicode 6.0.0.
+* New hook ArticlePrepareTextForEdit added, called when preparing text to be
+  saved.
+* New parser option PreSaveTransform added, allows the pre-save transformation
+  to be selectively disabled.
+* Alternative to $wgHooks implemented, using the new Hooks class.
+* Add width parameter to Special:Filepath to allow getting the file path of a
+  thumbnail.
+* (bug 26870) Add size to {{filepath:}}.
+* Upload warnings now show a thumbnail of the uploaded file.
+* Introduced the edittools-upload message, which will be inserted under the
+  upload form instead of edittools if available.
+* (bug 26285) Extensions will be automatically generated on upload if the user
+  specified a filename without extension.
+* (bug 26851) Special:UserRights now allows to prefill the reason field
+* New maintenance script to fix double redirects
+  (maintenance/fixDoubleRedirects.php).

+* (bug 29047) CSS/JS for each user group is imported from MediaWiki:Group-sysop.js,
+  MediaWiki:Group-autoconfirmed.css, etc.
+* (bug 24230) Uploads of ZIP types, such as MS Office or OpenOffice can now be
+  safely enabled. A ZIP file reader was added which can scan a ZIP file for
+  potentially dangerous Java applets. This allows applets to be blocked
+  specifically, rather than all ZIP files being blocked.
+* (bug 2429) Allow selection of associated namespace in recent changes.
+* (bug 26217) File size is now checked before uploading in HTML5 browsers.
+* CSS stylesheet MediaWiki:Noscript.css is now loaded for users with JavaScript
+  disabled (enclosed in the head in a <noscript> tag).

+* (bug 14645) When $wgMiserMode is on, expensive special pages are styled
+  differently (italicized by default) on Special:SpecialPages.
+* Added $wgAggregateStatsID, which allows UDP stats to be aggregated over
+  several wikis.
+* When $wgAllowMicrodataAttributes is true, all itemtypes are allowed, not just
+  the three that were defined in the original specification.
+* (bug 14706) Added support for the Imagick PHP extension.
+* (bug 18691) Added support for SVG rasterization using the Imagick PHP
+  extension.
+* (bug 2581, bug 6834) Added links to thumbnail in several resolutions to the
+  file description page. The sizes are set by $wgImageLimits.
+* (bug 28031) Add pageCount support to ArchivedFile.
+* (bug 27924) PhpHttpRequest doesn't return response body if HTTP != 200.
+* Added hook BitmapHandlerTransform to allow extension to transform a file
+  without overriding the entire handler.
+* The parser now attempts to output markers for editsection tokens and defer the
+  rendering of them post-cache to reduce parser cache fragmentation and ensure
+  skin customizability of edit section links.
+* (bug 24755) AuthPlugin auto-creation of local accounts can now be aborted by
+  other extensions by handling the 'AbortAutoAccount' hook, similar to the
+  'AbortNewAccount' triggered by explicit account creations. (They are separate
+  to avoid loops and confusion; auth plugins like CentralAuth need to handle
+  AbortNewAccount separately.
+* Special:ListFiles is now transcludable.
+* (bug 13879) Special:Emailuser asks for suitable target user if called without.
+* (bug 16956) IPTC and XMP metadata now extracted from images.

+  furthermore, it can import files from the filesystem using --image-base-path.
+* Three new hooks in Special:Undelete, 'UndeleteForm::showHistory',
+  'UndeleteForm::showRevision' and 'UndeleteForm::undelete', so that extensions
+  may override the usage of PageArchive class and replace it with their own
+  class that extends PageArchive.
+* (bug 28915) Implement QUnit test suite for MediaWiki JavaScript.
+  Also built-in support for distribution through a TestSwarm instance.
+* (bug 29036) For cascade-protected pages, the mw-textarea-cprotected class is

+  handle titles on case-sensitive wikis.
+* (bug 29397) Implement mw.Title module in core.
+* In MySQL 4.1.9+ with replication enabled, fetch the slave lag from SHOW SLAVE
+  STATUS instead of SHOW PROCESSLIST. This ensures that lag is reported
+  correctly in the case where there are no write events occurring. Note that
+  the DB user now needs to have the REPLICATION CLIENT privilege if you are
+  using replication.
+* Language codes in $wgDummyLanguageCodes are now excluded on localization
+  statistics (maintenance/language/transstat.php).
+* (bug 29586) Make the (next 200) links on categories link directly to
+  the relevant section of the category.
+* (bug 29109) Allow the automatic edit summary for redirect creation
+  show the first bit of the new redirect page.
+* (bug 29723) mw.util.wikiGetlink() now defaults to wgPageName.
+* (bug 29680) Add GetDefaultSortkey hook to override the default sortkey.
+* (bug 16699) {{#language:}} accepts second parameter to specify the language in
+  which the language name is wanted. Coverage depends on the cldr extension.

+  Supports editing of multiple categories and then saving them in one batch.
+* $wgAutopromoteOnce was added, allowing for users to be automatically promoted
+  to explicit usergroups. If a group is removed from a user via Special:UserRights,
+  it will not automatically be re-added. Configuration is similar to
+  $wgAutopromote (see DefaultSettings.php).

+  values for preferences a hook has been introdiced in User:getDefaultOptions().
+  Setting preferences in $wgDefaultUserOptions still work fine, but when reading
+  them (i.e. with array_keys) to get a list of all preferences, then
+  $wgDefaultUserOptions should no longer be used as it will contain those set via
+  User:getDefaultOptions().
+* (bug 30497) Add client-nojs and client-js classes on document element
+  to let styles easily hide or show things based on general JS availability.
+* (bug 31293) If Special:Userlogin is loaded over HTTPS, display
+  MediaWiki:loginend-https instead of MediaWiki:loginend, if it's not empty.
