Huddle Hub firmware and apps are defined by a 4 numbers version sequence:


[main].[major].[minor].[release]


All apps and firmware with the same main and major versions are mutually compatible, for example:


- 1.21.8.1 is compatible with 1.21.10.3

- 1.21.8.1. is NOT compatible with 1.22.0.1


We strongly suggest to update to the latest version anyway, for the best performances and most bug fixes.
