The software that is installed on your MICROBEAST ULTRA controller is what we call a "firmware". This firmware can be updated (i.e. for improvements, fixes, new features, ...) by downloading a file from the internet and flashing this on the device. To distinguish between firmware files each firmware has a unique version number "X.Y.Z" where "X" is the major version, "Y" is the minor version and "Z" is the patch version. You can say that when the major version ("X") changes then a lot will be different between two versions. When minor version "Y" increases, there will be a few new features or parameters. A change in "Z" is only a patch or fix that shouldn't be greatly noticable expect for some very little improvements. From our Changelog you can find out differences between versions. In general it is always recommended to stay with the latest version as this should give you the most features and benefits.
