New release packages with cffi 1.1.0 are available on bitbucket , note these are different than what I sent out before. https://bitbucket.org/pypy/pypy/downloads Please try them out, we have new buildslaves for win32, macosx and linux64. We would especially appreciate testing out the vmprof profiling features available on linux-64 Comments on the release notice are also welcome, extra points for guessing what "Cameo Charm" means. No fair checking IRC logs for hints. http://pypy.readthedocs.org/en/release-2.6.x/release-2.6.0.html Matti
