We've put a release candidate (1.2199) on the web. Here's a list of changes and new features:
http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.2199.html . If any of them appeal to you, please download the candidate and give it a whirl and let us know if you find any problems. The main motivation for getting this release out is so that web-fetching PDB files doesn't break in a few months (the previous release is using a legacy URL to the RCSB web site that will likely go away).
