We are glad to announce the first preview version 0.1 of kotlinx.collections.immutable library has been published to bintray.

This library contains interfaces of immutable persistent collections and their implementations. The implementation is based on pcollections . The maturity of this library is far from release, i.e. the implementations are not as optimal as they can be, and the API is subject to change in the future. However they convey our vision of immutable persistent collections and they are ready to try out.

The goal of this release is to provide some bits you can grab and plug into your project easily to play and experiment with. You can find the instructions how to setup the dependency in the README.

We are looking forward to your feedback.

Feel free to submit issues to github, ask questions here or in slack.
