pre-releaseone day ago

This is the fifty-fourth release in the Cats Effect 3.x lineage. It is fully binary compatible with every 3.x release and expected to be fully source-compatible with the eventual 3.6.x lineage. However, we did break binary-compatibility with the previous candidate v3.6.0-RC1.

This release candidate is expected to be very stable, and our main rationale for releasing it as such rather than as a full 3.6.0 is to allow the ecosystem (and adventurous end users!) to try it out and find unforeseen problems prior to full release. If fixing those problems require breaking compatibility prior to 3.6.0 (while maintaining bincompat with 3.x) we will do so, but otherwise you should expect this release to roughly represent the exact API surface area we will ultimately release.

Warning

Please note that Cats Effect 3.6.x is targeting Scala Native 0.4.x, which means it does not at present support native multithreading. This was a very intentional choice meant to give us an opportunity to break binary compatibility only on Scala Native if necessary when upgrading to Scala Native 0.5 and as we discover the impacts of the integrated runtime on the downstream ecosystem. It also reduces risk since Native multithreading in the runtime is a significant lift and we want to make sure we isolate that change from the already significant changes in 3.6.0. This functionality is already under development and we plan to release it in 3.7.0 as soon as possible.
