New Features

• Multiple job executions: a job can now have multiple executions running simultaneously. This will enable future support for long running scheduled jobs. Thanks @selwin!
• Worker(default_worker_ttl=10) is deprecated in favor of Worker(worker_ttl=10). Thanks @stv8!
• Added a cleanup parameter to registry.get_job_ids() and registry.get_job_count(). Thanks @anton-daneyko-ultramarin!
• Added support for AWS Elasticache Serverless Redis. Thanks @bobbywatson3!
• You can now specify TTL for deferred jobs. Thanks @hberntsen!
• RQ's code base is now typed (mostly). Thanks @terencehonles!
• Other minor fixes and improvements. Thanks @hongquan, @rbange, @jackkinsella, @terencehonles, @wckao, @sim6!

Breaking Changes

• Dropped support for Redis server < 4
