Yo, Updates to the issue tracker should now all hit the mailing list. The traffic over there is relatively low, but only a small handful of us actively check it - I'd prefer all information go to the same place. A few threads which should have been mailing list discussions have instead been held over there. This solves that problem :)
If it gets too spammy I'll separate it out into a -bugs mailing list. Since we used to do all bug discussions on the ML anyway, this should be no big deal. -Dormando
