Under Mac OS X 10.6 Snow Leopard, I’ve made good use of version control, Mercurial in my case. After upgrading to Mac OS X 10.6 Lion, I’ve discovered that quite a few files in my Mercurial repositories are now also managed by the new Versions feature.
I’m nonplussed by the situation. I’ve also utterly failed to find anything useful on the web, the combination of “Versions” and “version control” being pretty ambiguous.
What sort of issues might arise by both Mercurial and Versions coming into play? If I just ignore Versions, can I expect Mercurial to work transparently? Are there any opportunities offered by using the two together?
Versions is more like a backup. It saves a version every time you “save” (or periodically with autosave), so use it if you need to recover a version since your most recent commit to version control.
