@tekka Thank you very much for the response. I will just start migrating my existing nodes to MySensors v2.1.1library.

@tekka, I am planning to move from MySensors v2.0.0 to v2.1.1, do I need to use the updated MYSBootloader? Currently I am using MYSBootloader 1.3 pre-relase (https://forum.mysensors.org/topic/3453/mysbootloader-1-3-pre-release-myscontroller-1-0-0beta).

Can you please also help me understand the differences in the low_fuses and high_fuses values in the older version of bootloader and the latest version?
