Just to be clear, what's being proposed is some way to flag a release
on PyPI as being "stable" (or some other release as "unstable")? Then
a tool such as pip could prefer a stable release over an unstable
release while scraping download links from PyPI and all related pages?
How would this flag be presented to pip? How would a package
maintainer manage it?
Just a thought on the version number precedence rules: would using
"smypy-rc1-0.7.1" rather than "sympy-0.7.1-rc1" (ie. your version is
'rc1-0.7.1" instead of "0.7.1-rc1") work? It's a hack, I know, but I
had another look at the easy_install docs page and it's not clear to
me whether that would work. I think it might because it uses the same
basic work-around as the sympy-docs-html file.
