-In 1.18, the lowest supported version of MediaWiki is now 5.2.x. Please upgrade
+In 1.18, the lowest supported version of MediaWiki is now 5.2.3. Please upgrade
PHP if you have not done so prior to upgrading MediaWiki.
=== Configuration changes in 1.18 ===
* 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.
=== New features in 1.18 ===
* Added a special page, disabled by default, that allows users with the
potentially dangerous Java applets. This allows applets to be blocked

+* CSS stylesheet MediaWiki:Noscript.css is now loaded for users with JavaScript

+* (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 fixes in 1.18 ===
* (bug 23119) WikiError class and subclasses are now marked as deprecated
double HTML escaped
* (bug 27700) The upload protection can now also be set for files that do not
exist.
+* (bug 27763) Article::getParserOutput() no longer throws a fatal given when an
+ incorrect revision ID is passed.
+* Trim the form field for uploading by url to remove extra spaces which could
+ cause confusing error messages.
+* (bug 27854) Http::isValidURI is way too lax.
+* Do not show enotifminoredits preference, if disabled by $wgEnotifMinorEdits.
+* AbortLogin returning "ABORTED" now handled. Also allows message identifier
+ for "ABORTED" reason to be returned and displayed to user.
