This is the thirtieth release in the Cats Effect 3.x lineage. It is fully binary compatible with every 3.x release, and fully source-compatible with every 3.4.x release. Note that source compatibility has been broken with 3.3.x in some minor areas. Since those changes require active choice on the part of users to decide the best adjusted usage for their specific scenario, we have chosen to not provide scalafixes which automatically patch the affected call sites.
For a more comprehensive treatment of all changes between 3.3.x and 3.4.0, please see the RC1 release notes. The following notes only cover the changes between RC1 and RC2.
