$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.
