cats v2.2.0-RC1 Release Notes
Release Date: 2020-07-06 // almost 4 years ago-
🚀 This is the first release candidate for Cats 2.2.0, and it will become 2.2.0 if no major issues turn up in the next week or two. It includes some minor changes that technically break source compatibility with 2.2.0-M3 (for example), but these should not affect normal usage. It is backward binary compatible with 2.2.0-M3 and all 2.1.x and 2.0.x releases (and also with 1.x for the non-laws modules), but it is not binary compatible with 2.2.0-M1 or 2.2.0-M2.
🚀 Please note that this release follows 2.2.0-M3 in dropping support for Scala.js 0.6.
