Version 3.8 is out! For this long-delayed release (the release date we had set was June 2016!), we spent a lot of time focusing on platform stability and consistency, so this version is light on new features and heavy on bugfixes. We expect a similar situation for 3.9, since we still didn’t attend to everything we wanted in time for release.

If you’re already using 3.7.x, an upgrade is strongly recommended – there’s only a handful of API changes in 3.8 and most of them are unlikely to affect users.

SuperCollider still has 486 open issues and counting, so we need all the help we can get!

Here’s a selection of notable changes in this release:

General

  • Improved support for building sclang without Qt.
  • scvim is back in active development.
