Arrow v0.10.2 is now available

Today, we’re excited to announce the release of Arrow v0.10.2! We’re working toward improving the ergonomics as we approach 1.0.

Arrow is an open source library that’s packed with data types and type classes that empower pure functional programming in Kotlin.

Noteworthy changes in 0.10.2 include:

  • Fix crash on Android API < 21 by replacing usages of java.util.concurrent.atomic with Kotlin’s atomic-fu #1710.
  • Rework recursion schemes to be more modular #1384.

To see the full list of changes, closed issues, and merged PRs in 0.10.2, visit the official changelog for the complete overview.

We would like to give special thanks to the following contributors for this version (in no particular order):
