Yes, you do. Sometimes, rarely we push update only to some critical sections. In this case, only armbian-config was updated, while Armbian internal number or a majority of packages remained the same. A version number is taken from BSP (board support package). This means it won't change until that package gets an update. This usually happens at the major upgrade.
Nothing to worry.
If you find some specific problem with armbian-config, the best way is to open an issue ticket here:
