Suggestions for procedure going forward

We have had a number of ASDF 3 releases that have mostly been aimed at bug-fixing (although some new features have crept in).

I'd like to declare ASDF 3 feature complete and done, but I don't want to close the door to future bug fix releases as needed, nor do I want to shove incomplete new features out in order to get bug fixes out.

So I'd like to split ASDF development into stable and testing or something like that.

Does anyone have experience doing that? If so, please post suggestions for process to ASDF-devel.

Thanks! r
