I'm planning for two new features in @sidekiq 7.3.0:

1. A new job arguments serializer which can handle Symbols and other Rubyisms.
2. Add iteration support for better control with long-running jobs.

(2) will be based on @fatkodima's sidekiq-iteration gem which has been praised by several customers. I can't thank him enough for his ongoing work to improve Sidekiq.
