Hello everyone,
Change 554602 [1] proposes the removal without deprecation of the old extension schema
update globals. Those globals ($wgExtNewTables, $wgExtNewFields, $wgExtNewIndexes,
$wgExtPGNewFields, $wgExtPGAlteredFields and $wgExtModifiedFields) became obsolete with
1.17 and were replaced with the LoadExtensionSchema hook that passed a DatabaseUpdater
instance.
The phabricator task [2] lists all extensions that still reference those globals, but
these are already migrated to the hook and only use the globals for backwards
compatibility. The task also has a link to the code search query that lists all extensions
still referencing the globals.
