== Upgrading notes for 1.33 ==
1.33 has several database changes since 1.32, and will not work without schema
* MessageBlobStore::getBlob(), deprecated in 1.27, has been removed.
Use ::getBlobs() instead.
* The .background-size() LESS mixin, deprecated in 1.27, has been removed.
-* MWNamespace::clearCaches() has been removed. So has the $rebuild parameter
- to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
- Instead, create a new NamespaceInfo, such as by calling
- resetServiceForTesting( 'NamespaceInfo' ) on a MediaWikiServices.
- For classes that inherit from MediaWikiTestCase and used setMwGlobals() to
- modify a variable that affects namespaces, caches will automatically be
- reset and any calls to MWNamespace::clearCaches() can be removed entirely.
* ReadOnlyMode::clearCache() and ConfiguredReadOnlyMode::clearCache() have been
removed. Use MediaWikiTestCase::overrideMwServices() instead.
* Block::isValid is deprecated, since it is no longer needed in core.
* Calling Maintenance::hasArg() as well as Maintenance::getArg() with no
parameter has been deprecated. Please pass the argument number 0.
-* The MWNamespace class is deprecated. Use MediaWikiServices::getNamespaceInfo.
+* ResourceLoaderContext::expandModuleNames has been deprecated.
+ Use ResourceLoader::expandModuleNames instead.
