v2.13.1

• Fixed a subtle memory leak due to a function scoping change. The issue was introduced in v2.10.0.
• Improved how Groups expire Redis data fixed and an issue where blank Redis keys would be recreated even when a Group key was not being used. This issue was also introduced in v2.10.0 and tests have been added.

v2.13.0

• Added support for ES5 in Bottleneck v2. import Bottleneck from "bottleneck/es5";

v2.12.2

• Added Bottleneck.BottleneckError to the TypeScript typings file.

v2.12.1

• Optimized and improved accuracy of Batching

v2.12.0

• Added new standalone feature called Batching.
  new Bottleneck.Batcher({ maxTime: 1000, maxSize: 25 });
  See Documentation for more information.

v2.11.2

• Fixed Node process exiting early due to the reservoir reaching 0 when there are still queued jobs. This has been the source of much confusion for new users.
• Optimized entering Blocked Mode when using Clustering.

v2.11.1

• Fixed an issue with reservoir refresh where the very first refresh would happen too early.
• Reduced the heartbeat for local datastores to 250ms. It is still 5000ms for redis/ioredis datastores. This allows local limiters to set a reservoirRefreshInterval value as low as 250ms.

v2.11.0

• Added the ability to manually control the creation and reuse of Redis connections via the connection option and the Bottleneck.RedisConnection and Bottleneck.IORedisConnection objects.

v2.10.0

• Added the done() method which returns the total weight of completed jobs across the Cluster.
• Added a new "Reservoir Refresh" feature. Every reservoirRefreshInterval, the reservoir value is automatically reset to reservoirRefreshAmount.
• Fixed a number of edge cases with Clustering and improved its performance.

It is strongly recommended to upgrade to this version if you are using Clustering.

v2.9.0

• Added support for pubsub across the Cluster. Use the publish() method and listen to the message event on a limiter.
• Removed the need to wait for the ready() promise to complete before issuing commands. The commands will be queued until the limiter successfully connects. Make sure to listen to the error event to handle connection errors.
• Added the jobs() method to return a list of job ids in a specific state.
• Fixed an edge case with certain methods (like check()) when a Group key is recreated after timing out.
