* $wgSquidServersNoPurge now supports the use of Classless Inter-Domain
Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6
addresses that should be trusted to provide X-Forwarded-For headers.
-* Preferences 'watchcreations' and 'watchdefault' ("Add pages I create and files
- I upload to my watchlist", "Add pages and files I edit to my watchlist") are
- now enabled by default.
+* Preferences 'watchcreations', 'watchdefault', 'enotifwatchlistpages' ("Add
+ pages I create and files I upload to my watchlist", "Add pages and files I
+ edit to my watchlist", "Email me when a page or file on my watchlist is
+ changed") are now enabled by default.
* $wgLBFactoryConf: Class names have had underscores removed. The configuration
should be updated if LBFactory_Simple or LBFactory_Multi is configured.
* $wgPasswordSenderName has been deprecated. To set a custom mailer name,
* WikitextContent will now render redirects with the expected "redirect"
header, rather than as an ordered list. Code calling Article::viewRedirect
can probably be changed to no longer special-case redirects.
+* [[Special:Diff]] was added, allowing users to create internal links to
+ revision comparison pages using syntax such as [[Special:Diff/12345]],
+ [[Special:Diff/12345/prev]] or [[Special:Diff/12345/98765]].
