New Features

• A single_statement_dataset_destroy plugin has been added. This plugin will run the before_destroy hooks for all instances, then run a DELETE statement on the dataset, then run the after_destroy hooks for all instances. However, this optimized form will not be used if the model uses a custom around_destroy hook.

• The set_column_type schema modification method now supports a :collate option on PostgreSQL 9.1+ and MySQL.

Other Improvements

• The unused_associations plugin no longer reports associations with the :is_used option as unused. Previously, the :is_used option only disabled changes by the :modify_associations plugin option.

• Postgres::PGRange#to_s is now an alias of inspect, so it also uses the friendly inspect output added in 5.97.0.
