This is the first milestone release in the 2.3.x lineage, and the very first version of Cats Effect 2 to be published for Scala 3! Specifically, this release contains cross-builds for Dotty 0.27.0-RC1 and Scala 3.0.0-M1. We will continue tracking the latest two Scala 3 milestones until final upstream release. This is in addition to similar efforts on the Cats Effect 3 front. Exciting times!
