Processing [site | CDM tag] has been updating quite regularly. JOGL (site | onCDM) support has been updated to 1.1.1. Other changes are in the changelog. You can download from Processing.org, and check out CDM Labs to follow along with what Peter’s been doing in Processing recently.
Ed.: The JOGL changes are a big deal; I’m curious to see what improvements this may cause in render quality via the OpenGL renderer. Processing is nearing its real (non-beta!) 1.0 release, so expect a full-blown update on the progress of the tool soon; see Ben Fry’s recently-posted status report. -PK
