+* Fix bug where `ActiveSupport::Timezone.all` would fail when tzinfo data for
+ any timezone defined in `ActiveSupport::MAPPING` is missing.
+
+ *Dominik Sander*
+
+* Redis cache store: `delete_matched` no longer blocks the Redis server.
+ (Switches from evaled Lua to a batched SCAN + DEL loop.)
+
+ *Gleb Mazovetskiy*
+
* Fix bug where `ActiveSupport::Cache` will massively inflate the storage
size when compression is enabled (which is true by default). This patch
does not attempt to repair existing data: please manually flush the cache
