I’ve been told that parallel collections are going away in 2.13. However, I found this proposal that seems to indicate they are not going away, but rather just refactored into a different import. What is the plan?
Parallel collections are now available as a separate module: https://github.com/scala/scala-parallel-collections. You can check out the various other changes in the 2.13.0 release notes here: https://github.com/scala/scala/releases/tag/v2.13.0.
