 Apache Pekko 2.0.x releases support Java 17 and above.

+This is milestone release and is aimed at testing this new major version
+by early adopters. This is experimental. This release should not be used in production.
+
+We recommend that anyone using previous 2.0.0 milestones upgrade to this release due to some important bug fixes.

+See the [GitHub Milestone for 2.0.0-M3](https://github.com/apache/pekko/milestone/28?closed=1) for a fuller list of changes.

+### Bug fix
+
+* The existing 2.0.0 milestones have issues related to high concurrency introduced when we switched away from sun.misc.Unsafe to using Var Handles.
