Monix: Version 2.1.x

Greetings,

Version 2.1.1 is out now, while version 2.1.0 was out on Nov 9. The official announcement was then postponed because we waited to see if bug reports are going to happen. Today version 2.1.1 was released, fixing such a problem.

To use the new version, include this in your build.sbt (and use %%% for Scala.js):

libraryDependencies += "io.monix" %% "monix" % "2.1.1"

The new version supports:

  • Scala 2.10, 2.11 and 2.12
  • Scala.js 0.6.x
  • Cats 0.8.x
  • Scalaz 7.2.x
  • Java 6, 7, 8 and 9
  • Android, at least since 2.x

The theme of the 2.1 release has been performance optimizations, in some cases quite massive, improving Task and parallelizing work by means of the new Observable.mapAsync or by TaskSemaphore.

List of changes for 2.1.0:
