The parse_job_id function introduced in RQ version 2.0 breaks support for jobs with custom IDs containing :. If there are no plans to continue supporting such custom IDs, this should be clearly mentioned in the documentation.

For instance:

queue = Queue('queue_name', connection=connection)
queue.enqueue_call(func, job_id='job:1')
worker = Worker(queue)
assert worker.work(burst=True)
