queue.enqueue_many() now supports on_success and on on_failure arguments. Thanks @y4n9squared!
You can now pass enqueue_at_front to Dependency() objects to put dependent jobs at the front when they are enqueued. Thanks @jtfidje!
Fixed a bug where workers may wrongly acquire scheduler locks. Thanks @milesjwinter!
Jobs should not be enqueued if any one of it's dependencies is canceled. Thanks @selwin!
Fixed a bug when handling jobs that have been stopped. Thanks @ronlut!

@mattchan-tencent

This will be the last RQ version that supports Python 3.5.
Allow jobs to be enqueued even when their dependencies fail via Dependency(allow_failure=True). Thanks @mattchan-tencent, @caffeinatedMike and @selwin!
When stopped jobs are deleted, they should also be removed from FailedJobRegistry. Thanks @selwin!
job.requeue() now supports at_front() argument. Thanks @buroa!
Added ssl support for sentinel connections. Thanks @nevious!
SimpleWorker now works better on Windows. Thanks @caffeinatedMike!
Added on_failure and on_success arguments to @job decorator. Thanks @nepta1998!
Fixed a bug in dependency handling. Thanks @th3hamm0r!
Minor fixes and optimizations by @xavfernandez, @olaure, @kusaku.

@ericman93

Failure callbacks are now properly called when job is run synchronously. Thanks @ericman93!
Fixes a bug that could cause job keys to be left over when result_ttl=0. Thanks @selwin!
Allow ssl_cert_reqs argument to be passed to Redis. Thanks @mgcdanny!
Better compatibility with Python 3.10. Thanks @rpkak!
job.cancel() should also remove itself from registries. Thanks @joshcoden!
Pubsub threads are now launched in daemon mode. Thanks @mik3y!

@rpkak

You can now enqueue jobs from CLI. Docs here. Thanks @rpkak!
Added a new CanceledJobRegistry to keep track of canceled jobs. Thanks @selwin!
Added custom serializer support to various places in RQ. Thanks @joshcoden!
cancel_job(job_id, enqueue_dependents=True) allows you to cancel a job while enqueueing its dependents. Thanks @joshcoden!
Added job.get_meta() to fetch fresh meta value directly from Redis. Thanks @aparcar!
Fixes a race condition that could cause jobs to be incorrectly added to FailedJobRegistry. Thanks @selwin!
Requeueing a job now clears job.exc_info. Thanks @selwin!
Repo infrastructure improvements by @rpkak.
Other minor fixes by @cesarferradas and @bbayles.

@selwin

Added success and failure callbacks. You can now do queue.enqueue(foo, on_success=do_this, on_failure=do_that). Thanks @selwin!
Added queue.enqueue_many() to enqueue many jobs in one go. Thanks @joshcoden!
Various improvements to CLI commands. Thanks @rpkak!
Minor logging improvements. Thanks @clavigne and @natbusa!

@skieffer

You can now declare multiple job dependencies. Thanks @skieffer and @thomasmatecki for laying the groundwork for multi dependency support in RQ.
Added RoundRobinWorker and RandomWorker classes to control how jobs are dequeued from multiple queues. Thanks @bielcardona!
Added --serializer option to rq worker CLI. Thanks @f0cker!
Added support for running asyncio tasks. Thanks @MyrikLD!
Added a new STOPPED job status so that you can differentiate between failed and manually stopped jobs. Thanks @dralley!
Fixed a serialization bug when used with job dependency feature. Thanks @jtfidje!
clean_worker_registry() now works in batches of 1,000 jobs to prevent modifying too many keys at once. Thanks @AxeOfMen and @TheSneak!
Workers will now wait and try to reconnect in case of Redis connection errors. Thanks @Asrst!

@selwin

Added job.worker_name attribute that tells you which worker is executing a job. Thanks @selwin!
Added send_stop_job_command() that tells a worker to stop executing a job. Thanks @selwin!
Added JSONSerializer as an alternative to the default pickle based serializer. Thanks @JackBoreczky!
Fixes RQScheduler running on Redis with ssl=True. Thanks @BobReid!

@selwin

Worker now properly releases scheduler lock when run in burst mode. Thanks @selwin!

@selwin

Workers now listen to external commands via pubsub. The first two features taking advantage of this infrastructure are send_shutdown_command() and send_kill_horse_command(). Thanks @selwin!
Added job.last_heartbeat property that's periodically updated when job is running. Thanks @theambient!
Now horses are killed by their parent group. This helps in cleanly killing all related processes if job uses multiprocessing. Thanks @theambient!
Fixed scheduler usage with Redis connections that uses custom parser classes. Thanks @selwin!
Scheduler now enqueue jobs in batches to prevent lock timeouts. Thanks @nikkonrom!
Scheduler now follows RQ worker's logging configuration. Thanks @christopher-dG!
