run your wiki with $wgActorTableSchemaMigrationStage SCHEMA_COMPAT_READ_OLD,
note that log_search rows needed to find revision deletions by target user
were incorrectly deleted. See T215464 for details.
+* If revision deletions were performed when the wiki was configured with
+ $wgActorTableSchemaMigrationStage SCHEMA_COMPAT_WRITE_BOTH and without
+ migrateActors.php having been run, the log_search table may contain rows with
+ empty values for "target_author_actor" which will prevent log searches for
+ revision deletions by target user from finding those log entries. These rows
+ may be corrected by (re-)running migrateActors.php.

is no longer a problem, because the code now ensures the timestamp is always
higher than the previous one. The writes are guarded with CAS logic (check
and set), which prevents updates that would overlap.
+* $wgDBmysql5 (T196185) - This experimental setting, deprecated in 1.31, has
+ been removed.
=== New user-facing features in 1.33 ===
* (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
* Added jakub-onderka/php-console-highlighter 0.3.2 explicitly (dev-only).
==== Changed external libraries ====
-* Updated OOUI from v0.29.2 to v0.31.0.
+* Updated OOUI from v0.29.2 to v0.31.2.
* Updated OOjs Router from pre-release to v0.2.0.
* Updated moment from v2.19.3 to v2.24.0.
* Updated wikimedia/xmp-reader from 0.6.0 to 0.6.2.
Use CdnCacheUpdate::newFromTitles() instead.
* Handling of multiple arguments by the Block constructor, deprecated in 1.26,
has been removed.
+* The translation of main page in Sardinian (sc) was changed from "Pàgina Base"
+ to "Pàgina printzipale". Existing wikis using this content language need to
+ move the main page or change the name through MediaWiki:Mainpage page.
=== Deprecations in 1.33 ===
* The configuration option $wgUseESI has been deprecated, and is expected
* ManualLogEntry::setTags() is deprecated, use ManualLogEntry::addTags()
instead. The setTags() method was overriding the tags, addTags() doesn't
override, only adds new tags.
+* Block::isValid is deprecated, since it is no longer needed in core.
=== Other changes in 1.33 ===
* (T201747) Html::openElement() warns if given an element name with a space
changed to explicitly cast. Subclasses relying on the base-class
implementation should check whether they need to override it now.
* BagOStuff::add is now abstract and must explicitly be defined in subclasses.
+* LinksDeletionUpdate is now a subclass of LinksUpdate. As a consequence,
+ the following hooks will now be triggered upon page deletion in addition
+ to page updates: LinksUpdateConstructed, LinksUpdate, LinksUpdateComplete.
+ LinksUpdateAfterInsert is not triggered since deletions do not cause
+ insertions into links tables.
