Fabric OS Release Version Classification
Fabric OS release versions are identified by three integers and an optional alphabetic letter using the following syntax:

FOS <Generation Number>.<Major Number>.<Maintenance Number>[<Patch Letter>].

- Generation – The first integer identifies significant functional changes due to core hardware or software architecture changes.
- Major – The second integer identifies major new software functional changes for new features and platform support.
- Maintenance – The third integer identifies a minor release for defect fixes, selected enhancements, or support of hardware variations.
- Patch – A lowercase alphabetic letter identifies a release version for defect fixes.
