ZIO 1.0.0-RC21 was released last weekend, bringing the long-awaited changes of the supervision model that were considered the last thing missing to publish version 1.0. From this point, no significant API changes are expected and efforts will be focused on fixing any bugs that are identified as well as polishing the API and documentation for the 1.0 release. Please report any issues you experience with this RC so that the team can address them immediately.
Here are the release notes
for this version. Other changes include, among other things, performance improvements for Chunk, a new data type for STM called TPriorityQueue and various improvements and fixes on ZStream.
