Sidekiq v4.1.3 Release Notes
-
- Please note the Redis 3.3.0 gem has a memory leak, Redis 3.2.2 is recommended until that issue is fixed.
- Sinatra 1.4.x is now a required dependency, avoiding cryptic errors and old bugs due to people not upgrading Sinatra for years. [#3042]
- 🛠 Fixed race condition in heartbeat which could rarely lead to lingering processes on the Busy tab. [#2982] ```ruby
