Full Changelog: v2.8.0...v2.9.0
Performance improvement
In version v2.9.0, ants introduces two new pool types: MultiPool and MultiPoolWithFunc from which you will benefit the
performance improvement on the basis of the fine-grained locking that reduces the lock contention.
These two pools are a good fit for the scenario where you have a large number of tasks to submit, and you don't want the single pool to be the bottleneck.
