Human-in-the-Loop - approve knob changes before they are applied to your database.
New Target Objectives - support for p99 query latency and CPU utilization as target objectives options for tuning.
Fixed issue in the Configurations tab where the list of knobs displayed would not reset when selecting a different configuration.
Service Update 2021-10-13
Containerized OtterTune Agent - we support an open-source agent running on your hosts that can collect database metrics without our service needing direct network access to your database.
CloudFormation templates - it is now much easier to provision your OtterTune IAM role and the agent

Configuration Versioning - see how your Database parameter group changes overtime
Fixed issue where we were always treating changes to the MySQL parameter innodb_thread_sleep_delay as new configuration changes. This parameter is updated by InnoDB automatically when innodb_adaptive_max_sleep_delay is set. Now, we no longer treat automatic changes to innodb_thread_sleep_delay as a new configuration.
Fixed y-axis issue on charts where we were not appropriately subdividing for small ranges
Fixed issue where we would incorrectly display an error message suggesting that users' agents have been disconnected if they stayed on the database overview page for too long.
Fixed issue where we lost track of a user's parameter group ARN when they switched from Tuning mode to Monitoring mode.
