> A library that has a history of regular maintenance is unlikely to get suddenly dropped. And a library that has a large user base will have its maintenance picked up by others if the original maintainer(s) do step down. If the library doesn't meet these criteria then you probably shouldn't be using it.} Projects die all the time or start being very lazy with the maintenance. Not that I expect anything more, there is literally no money in them. The criteria I like to use is "Will I be able to fork it and fix it when it goes unmaintained"?
