PLT-OS v1.10

PLT-OS v1.10.x is the current Stable release track, supporting PLT-200A and PLT-300A.


PLT-OS v1.9.x introduced a new system partition sizing, to allow for supporting programming targets and other enhancements. This makes PLT-OS v1.10.x unable to revert to pre-v1.8 PLT-OS versions.

If a unit running v1.10.x needs to be downgraded to a pre-v1.8 version, it should first be downgraded to the most recent PLT-OS v1.8 release.
