Changes are listed below, grouped under each point release of SuperCollider.

Recent changes (will be SuperCollider v3.3.2)
=======================================

Headlines:
----------

* 2009-09-03 add support for Mac OS 10.5 and greater 64-bit builds of plugins and scsynth

* 2009-07-31 mac osx text-completion feature now includes sclang objects - ds
* 2009-08-01 sclang now has a flag (Platform.ideName) for which IDE is in use (scapp, scvim, scel, sced, jsceclipse...) so that the same class-library can be used with different IDEs, enabling IDE-specific code as necessary - ds
* 2009-08-16 add emergency escape route: if sclang is caught in an infinite loop, send it a USR1 signal to break out of it - ds
* 2009-09-12 String:findRegexp and other regular expressions now available on linux as well as mac - mb,ds

* 2009-10-04 support multichannel indices for Env:at - jr
* 2009-10-29 improve OSC message correctness: for convenience, sclang allows command names as symbols with no leading slash e.g. \g_new. To improve compliance with the OSC standard, the leading slash is now added to those symbols before dispatch - ds
* 2009-11-04 new SCAnimationView and update of deferredTaskInterval from 0.038 to 0.01667 - fo

* 2009-11-28 windows: system "application support path", previously hardcoded as C:\SuperCollider, now settable by environment variable SC_SYSAPPSUP_PATH. Default setting for that env var (when using official wix bundle) will be [SC3INSTALLLOCATION] - ds
* 2009-12-15 sclang: 64bit safety - tb
* 2009-12-15 sclang: performance improvement of math ops - tb
* 2010-01-02 scsynth: use osc-compilant address patterns for server/lang communication - tb

* 2009-08-01 SpecCentroid, fix its reaction to silence (output zero instead of NaN) - ds
