LOL most of those were iterative bug fix releases.
Amiupdate has delivered very many free updates to AmigaOS4.1. Good knows what version number it would be up to if they followed MOS and bumped the version number with every minor fix. :laugh1:
Actually, every second release (odd version numbers) was a bugfix release, and between them there were the major updates (with even version numbers). About what a major update was, you can check the details yourself, because - unlike OS4 - all changes are still publicly listed in the
respective release notes on the official MorphOS page. :rtfm:
