Embedded Systems have complex software
(*)Like any complex system, it can be split in smaller pieces to separate concerns.

Softcrates makes sure that all the different components work correctly with the latest version
and will be consolidated in a single image release cycle.
Also there is a LTS (Long-TermSupport)
version that freezes a release and
bugfixes are backported for N years
Each Component has a different release cycle.
