+* (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
+ Title::getDBKey(), which doesn't vary case.
+* User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
+ returns the same information in a more useful format.
+* For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
+ as the $lang parameter was deprecated. The same applies to DummyLinker.
+* The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
+ follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
+ instead which blacklists 100,000 commonly used passwords.
+* (T208862) Action::requiresUnblock() is now called from
+ Title::getUserPermissionsErrors() and Title::userCan(). Previously, the method
+ was only called in Action::checkCanExecute(). Actions should ensure that their
+ requiresUnblock() returns the proper result (the default is `true`).
