I've partially rewritten the StableVersion extension. It now can * store multiple stable versions (someone wanted this; I can turn that off) * store multiple types (not actually supported yet, but the potential is included), e.g.: ** stable ** stable candidate (someone wanted this) ** "soft-protected" ** other "levels of stability" like "thoroughly reviewed"

And most important: When you click on the "declare this stable" link, it now caches the source *with replaced templates*, meaning the stable page will look the same even if the templates it uses were changed or deleted.

With some help *ahem* the feature could go live this year, IMHO.
