Hi all, RevDB (https://bitbucket.org/pypy/revdb), the reverse debugger, was updated to 5.6.x. It contains a few RevDB-specific fixes as well. See the new tag RevDB-pypy2.7-v5.6.1 in the repository, or on direct download at https://bitbucket.org/pypy/pypy/downloads?tab=tags . Please contact me if you'd really like Windows support. A bientôt, Armin.
