I was trying to push a patch but it seems I am not a committer anymore. My name vanished of https://hg.python.org/committers.txt and the tracker.
I guess I had a DSA key in hg.python.org and those are not valid anymore, but looks like I am not a documented committer anymore in order to send a new 2048 bits RSA key.
I don't know if this is a mistake or a decision. Just let me know.
