The 1.1.0-M1 (soon to be relabeled as 2.0) release is mostly source compatible with 1.0.x, with a handful of exceptions:

  • replaced use of blocking execution contexts with cats.effect.Blocker
  • changed TCP/UDP support to use SocketGroup
  • maybe changed Pull#stream and Pull#streamNoScope to require result type to be Unit

A scalafix upgrade script that automates as much of those as possible would be fantastic.

It would be twice as fantastic if the Scalafix migration would then be added to Scala Steward before the final release. :-)
