* 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
* 'xx-uca-et' (CollationEt) - use 'uca-et' instead
* 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
+* LanguageCode::bcp47() now always returns a valid BCP 47 code. This means
+ that some MediaWiki-specific language codes, such as `simple`, are mapped
+ into valid BCP 47 codes (eg `en-simple`).
* The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated
in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'.
The ChangesListSpecialPage code for these legacy hooks, and their use in
assert a newer version of PHP than MediaWiki does, use extension registration.
* The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been
removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
+* DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
+* File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
+* The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use
+ the hook 'SkinEditSectionLinks' instead.
+* The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
+* The global function wfRunHooks, deprecated since 1.25, has now been removed.
+ Use Hooks::run().
+* The hook 'UnknownAction', deprecated since 1.19, has now been removed.
+* The hook 'ParserLimitReport', deprecated since 1.22, has been removed. Use
+ the hooks 'ParserLimitReportPrepare' and 'ParserLimitReportFormat' instead.
=== Deprecations in 1.32 ===
* HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
as a string. They should be given as a OOUI\FieldLayout object instead.
Notably, this affects fields defined in the 'GetPreferences' hook, because
Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
+* In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is
+ deprecated. For the $lang parameter, types other than Language are
+ deprecated.
