- Faster phased restart and worker timeout (#2220)
- Added state_permission to config DSL to set state file permissions (#2238)
- Added Puma.stats_hash, which returns a stats in Hash instead of a JSON string (#2086, #2253)
- rack.multithread and rack.multiprocess now dynamically resolved by max_thread and workers respectively (#2288)
