Here are some of the latest updates, projects, talks, articles, and events in the Functional Programming community:

Scala.js 0.6.17 was released on June 4th and includes a few new feature and a bunch of bug-fixes.

Bug fixes in this release include:

#2943/#2827 - fixes performance regression in the optimizer and slow incremental linking times for fastOptJS (with ScalaTest)
#2845 - fixes issue where Scala.js compilier wasn’t passing through UTF-8 correctly for dependencies
#2798 - Allows the sbt plugin to work when run on Java 9

The main new feature, according to the release is, “ the ability for facade libraries to support both the traditional NoModule style, where JS libraries are exposed as global variables and accessed through @JSGlobal, and the CommonJSModule style, where JS libraries are imported through @JSImport.”

You can read the full announcement here: Announcing Scala.js 0.6.17.

Freestyle simplifies and promotes applications and libraries built on top of a purely functional style.

Version 0.2.0 released this week and focuses on optimizations on the runtime for faster evaluations of handlers and runtime optimization over the Coproduct algebra lookup. New features and bug fixes include:

#310 - Adds FunctorK for finally tagless
#315 - Optimization: Replace FunctionK pattern matching with JVM switch for faster @free programs
#326 - Use nested coproduct list support from Iota 0.2.x
