New Features¶ ↑

• On Ruby 3.2, the pool_class: :timed_queue Database option can now be used to use an alternative connection pool that stores connections in a queue, and uses the new Queue#pop :timeout option in Ruby 3.2 to implement the pool timeout. This new connection pool is simpler than the default connection pool. It is not yet the default connection pool on Ruby 3.2, but it may become the default in a later version. Users of Ruby 3.2 are encouraged to try out the pool_class: :timed_queue Database option and provide feedback on how it works in their application.

Other Improvements¶ ↑

• The tactical_eager_loading plugin now works in combination with the single_table_inheritance and class_table_inheritance plugins, when loading an association only defined in a specific subclass. Previously, eager loading would be skipped in such a case. Now, an eager load will be attempted for all instances supporting the association.

• The validate_associated plugin now avoids database type errors for non-integer association keys. In cases where the associated object doesn’t have a value for the associated key, and the current object does not have a key value that can be set in the associated object, validation errors in the associated object related to the associated key will be ignored.

• Thread-keyed connection pool hashes now use compare_by_identity for better performance.

• The JRuby workaround in the named_timezones extension is no longer used on JRuby 9.3.9.0+, as JRuby fixed the related bug.
