+=== PHP 5.2 now required ==
+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 WantedPages::getSQL hook has been removed and replaced with
WantedPages::getQueryInfo . This may break older extensions.
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.
=== New features in 1.18 ===

+* (bug 24230) Uploads of ZIP types, such as MS Office or OpenOffice can now be

+ extension

+* (bug 27924) PhpHttpRequest doesn't return response body if HTTP != 200
