We've just put out a major new release of Unison. It includes a snazzy new UI for browsing Unison codebases, a new computable documentation format, a new faster runtime, and a new SQLite-based codebase format that substantially improves codebase performance.

Summer collaboration with Heather Miller on Unison distributed programming library

Exciting news! Heather Miller, CMU professor and Scala Center founder, who does very cool research at the intersection of programming languages, FP, and distributed systems, will be a Visiting Researcher with us this summer. Like us, Heather is passionate about finding ways to make distributed programming more compositional. We'll be collaborating together on a library for distributed computing in Unison and some interesting demo application using that library.

People are writing Unison libraries now

It's exciting to see Unison gradually coming together, but even more exciting has been seeing people writing and publishing Unison code. I've been pretty busy reviewing pull requests to the Unison base libraries and there's already a lot of useful stuff there. Thanks to everyone who has contributed so far!

How Unison reduces ecosystem churn

Unison doesn't have library dependency conflicts, and many sources of ecosystem churn just disappear. This fact got a brief mention in the Strange Loop 2019 talk, but that talk didn't make all the benefits totally clear. This article will attempt to highlight some of the more surprising benefits of Unison's approach.
