+*   Removed redundant override of `xml` column definition for PG,
+    in order to use `xml` column type instead of `text`.
+
+    *Paul Nikitochkin*, *Michael Nikitochkin*
+
+*   Revert `ActiveRecord::Relation#order` change that make new order
+    prepend the old one.
+
+    Before:
+
+        User.order("name asc").order("created_at desc")
+        # SELECT * FROM users ORDER BY created_at desc, name asc
+
+    After:
+
+        User.order("name asc").order("created_at desc")
+        # SELECT * FROM users ORDER BY name asc, created_at desc
+
+    This also affects order defined in `default_scope` or any kind of associations.
+
+*   Add ability to define how a class is converted to Arel predicates.
+    For example, adding a very vendor specific regex implementation:
+
+        regex_handler = proc do |column, value|
+          Arel::Nodes::InfixOperation.new('~', column, value.source)
+        end
+        ActiveRecord::PredicateBuilder.register_handler(Regexp, regex_handler)
+
+    *Sean Griffin & @joannecheng*
+
+*   Don't allow `quote_value` to be called without a column.
+
+    Some adapters require column information to do their job properly.
+    By enforcing the provision of the column for this internal method
+    we ensure that those using adapters that require column information
+    will always get the proper behavior.
+
+    *Ben Woosley*
+
+*   When using optimistic locking, `update` was not passing the column to `quote_value`
+    to allow the connection adapter to properly determine how to quote the value. This was
+    affecting certain databases that use specific column types.
+
+    Fixes: #6763
+
+    *Alfred Wong*
+
+*   rescue from all exceptions in `ConnectionManagement#call`
+
+    Fixes #11497
+
+    As `ActiveRecord::ConnectionAdapters::ConnectionManagement` middleware does
+    not rescue from Exception (but only from StandardError), the Connection
+    Pool quickly runs out of connections when multiple erroneous Requests come
+    in right after each other.
+
+    Rescuing from all exceptions and not just StandardError, fixes this
+    behaviour.
+
+    *Vipul A M*
+
+*   `change_column` for PostgreSQL adapter respects the `:array` option.
+
+    *Yves Senn*
+
 *   Remove deprecation warning from `attribute_missing` for attributes that are columns.
