Hi all, Here's the release candidate for PyPy 2.2.1 on Windows: it fixes the json decoding, and adds Tk support (thanks Matti!). Please tell me if there is some problem with it. http://buildbot.pypy.org/nightly/release-2.2.x/pypy-c-jit-68207-1567dba349e6-win32.zip On other platforms, PyPy 2.2.1 will not be released, as nothing changed. A bientôt, Armin.
