Since my last update, we’ve merged about 10 additional PRs for RC1.
There are now no known RC1 blocker bugs, and only one in-flight PR that Adriaan is working to finish (PR 7929).
As for the community build, thanks to community help with https://github.com/scala/bug/issues/11453, we’re up to 94 green projects now, and in addition, a number of not-yet-green projects were investigated and determined not to have uncovered Scala regressions.
Akka is the remaining community build project we want to either get green, or verify that any failures are harmless. Akka is important both as a cornerstone of a sector of the Scala ecosystem, and as a test of the viability of the new stdlib APIs that replace the scala-java8-compat module.
Lukas now has Akka compiling with the latest Scala nightly, but there are test failures that remain to be investigated.
