= New Features
* Database#{defer,immediate}_constraints methods have been added on
PostgreSQL for changing handling of deferrable constraints inside
a transaction. defer_constraints sets deferrable constraints to
be deferred (not checked until transaction commit), and
immediate_constraints sets deferrable constraints to be checked
as part of the related query, and any already deferred constraint
checks to be applied immediately. You can pass the :constraints
option to only apply the changes to specific constraints.
* TimestampMigrator.run_single has been added, to migrate a single
migration up or down.
= Other Improvements
* INSERT RETURNING is now supported on MariaDB 10.5+, and used
automatically when saving new model objects. Note that this
is not supported when using the jdbc adapter, because the
jdbc-mysql driver doesn't support it. A jdbc/mariadb adapter
could be added, as it's likely recent versions of the
jdbc-mariadb driver would support it, but the jdbc-mariadb gem
hasn't been updated in over 4 years. Talk to the jdbc-mariadb
gem maintainers if you want to use this feature with the jdbc
adapter.
* The Dataset#paged_each optimization in the postgres adapter
now respects the :skip_transaction option, making it the
same as the :hold option. Note that this has effects beyond
just skipping the transaction, but non-HOLD cursors are only
supported inside transactions.
* The any_not_empty? extension's Dataset#any? method now supports
an argument, passing it to Enumerable#any? (which has supported
an argument since Ruby 2.5).
