+* Loading model schema from database is now thread-safe.
+
+ Fixes #28589.
+
+ *Vikrant Chaudhary*, *David Abdemoulaie*
+
* Add `ActiveRecord::Base#cache_version` to support recyclable cache keys via the new versioned entries
in `ActiveSupport::Cache`. This also means that `ActiveRecord::Base#cache_key` will now return a stable key
that does not include a timestamp any more.
