We have an OnPrem Proget server.

When our devs after working they may find that they need to modify a package to allow the app they are actually working on to work. This means that we can end up with a number of Prerelease builds of packages on the server as they need to get to there so they can be properly fetched during the build of the target app.

Is there an accepted Code of Practice for managing prerelease stuff? Do people publish prerelease stuff to a different feed and only post the released stuff to the more public feed? Or is it just expected that once the release is out that the prerelease builds are simply removed from the feed?
