+* 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.
+
+ NOTE: This feature is turned off by default, and `#cache_key` will still return cache keys with timestamps
+ until you set `ActiveRecord::Base.cache_versioning = true`. That's the setting for all new apps on Rails 5.2+
+
+ *DHH*
+
+* Respect `SchemaDumper.ignore_tables` in rake tasks for databases structure dump
+
+ *Rusty Geldmacher*, *Guillermo Iguaran*
+
* Add type caster to `RuntimeReflection#alias_name`
Fixes #28959.
