pending:

• scala-ssh
  • upstream PR: support Scala 2.12.0 veact/scala-ssh#5
  • but maybe it's fine to just keep tracking @xuwei-k's fork

forked because of Coursier:

• fastparse
  • issue: regression: fastparse failing because it uses coursier now #294

forked only because of bintray-sbt (lightbend-labs/dbuild#158):

• active: akka-contrib-extra, akka-http, akka-sse, scalamock
• moribund: sbinary, sbt-testng

list is up to date as of: December 14, 2016

a previous round of work on this was done in #322

I should probably expand this list to include freezes, which are just a degenerate case of forking, really

[SethTisue]

I've opened #629 on the coursier situation

[SethTisue]

the number of remaining forks is not that great, and having some freezes is not so bad, either. let's declare victory. the current state of things good enough, overall. we can continue to evaluate individual cases individually
