When I gave the PSF members an update on the work to move the python-dev tracker over to Roundup Andrew Kuchling asked me to also send an email to python-dev since October/November.
As of right now the biggest thing holding up the transition is documentation. A doc needs to get written explaining basic workflow of how issues should be handled. Also need to go through and remove SF references and make them more general (e.g., mention an "issue tracker" when possible).
After that some redirects need to be tweaked. www.python.org/sf/ needs to redirect to the Roundup installation (which is keeping SF bug numbers). bugs.python.org will also be set to point to the Roundup server.
After all of that we will find out from Anthony and Neal when a release is going to be so as to do the switch when it won't run into a release (before or after).
The current test tracker is at http://psf.upfronthosting.co.za/roundup/tracker/ . The meta tracker for dealing with this stuff is at http://psf.upfronthosting.co.za/roundup/meta/ . Feel free to have a look, but please don't go overboard with the suggestions on changes. It is not difficult to change the tracker after it launches. The last thing any of us want to see is the tracker launch delayed because someone wants a feature that takes a while to implement. Unless there is a critical issue you find it would be appreciated if you file the suggestion and just let us push after the launch if it is deemed it will take too much time to implement.
The mailing list where all discussions take place is http://mail.python.org/mailman/listinfo/tracker-discuss . Fairly low-traffic although all updates to the meta tracker get sent there.
Obviously if you have questions feel free to ask. And if you want to help with getting the switch to happen just speak up. =)
