We’ve been working on a new release of SuperCollider, and the first preview version is now available.

Mac downloads: https://sourceforge.net/projects/supercollider/files/Mac%20OS%20X/3.4alpha/
Source downloads: https://sourceforge.net/projects/supercollider/files/Source/3.4alpha/
Ubuntu debs: https://launchpad.net/~supercollider/+archive/ppa

3.4 includes many many improvements over 3.3.1, including great work on full 64-bit support for mac and linux - detailed changelog here: http://tinyurl.com/sc34ach

It’s an “alpha” release meaning there may still be some tweaks that we need to fix before the final 3.4 release, so we’d be grateful for feedback.
