That's a good question. The modifying sentence is the critical part: would there be any change to the bytecodes generated?

Anyone with a truly critical need is free to download the patch and recompile. Overall, I see patch releases as coinciding with feature releases so that people can concentrate on doing the same kind of work at the same time. > I'm also not sure if a beta cycle in a bugfix release is really necessary, > especially a month long one.

It slows the release pace and -- given the usually high quality of Python betas -- it encourages people to try them out. I believe that we *do* need patch betas for system testing. >> Should the first patch release following any feature release be >> required to be a bug fix release?

That is *precisely* why my original proposal suggested that only the N-1 release get patch attention, to conserve effort.
