 - rediscloud_subscription_database (Redis 8.0+): Fixed drift detection issues where explicitly configured modules would incorrectly show as changes requiring resource replacement after upgrading to Redis 8.0 or higher. Modules are bundled
   by default in Redis 8.0+, so configuration differences are now properly suppressed.
 - rediscloud_subscription_database (Redis 8.0+): The warning for modules has been made more prominent.
+- Support for a new pending status for subscription and database updates.
 - Test Suite: Fixed incorrect file path references in acceptance tests.
