Pekko 1.2.0 has some new features, performance updates and dependency upgrades. See [GitHub Milestone for 1.2.0-M1](https://github.com/apache/pekko/milestone/6?closed=1), [GitHub Milestone for 1.2.0-M2](https://github.com/apache/pekko/milestone/15?closed=1) and [GitHub Milestone for 1.2.0](https://github.com/apache/pekko/milestone/16?closed=1) for a fuller list of changes.
