=== Bug fixes in 1.27 ===
* Special:Upload will now display correct maximum allowed file size when running
under HHVM (T116347).
+* (T54077) The APIEditBeforeSave hook will once again give only the content of
+ the section being edited, rather than the whole revision. This reverts the
+ change made in MediaWiki 1.22.
=== Action API changes in 1.27 ===
* Added list=allrevisions.
* User::isPasswordReminderThrottled() was deprecated.
* Bot-oriented parameters to Special:UserLogin (wpCookieCheck, wpSkipCookieCheck)
were removed.
+* Installer can now be customized without patching MediaWiki code, see
+ mw-config/overrides/README for details.
