Sometimes ROOT users get bitten by nasty bugs, and we ROOT developers try our best to squash them as quickly as possible. New features and improvements are also constantly merged in ROOT’s main development branch, either coming from ROOT developers or as contributions from the community.

Or, you know, compile the very latest ROOT from source code – but nobody has time for that!
