I'm not sure yet if it will be called 1.4.1 or 1.5.0.
The criteria I use for bumping 1.4 to 1.5 would be new features. Right now there are only bug fixes. We may call it 1.5 if anyone commits anything major. I think it will be a good idea to do it, as there are a few component upgrades there. -- Clebert Suconic
