A new version of the HSMM-Mesh node software has been released. And with the new release, comes a change in the name. The non-intuitive, albeit nice and short "HSMM-Mesh" has changed to a fairly cumbersome, but descriptive "Broadband-Hamnet" I'll leave it to you to determine if that is a good thing or a bad thing.
At any rate, the new software WILL NOT communicate with the old, so upgrading is an all or nothing proposition. Basically, if we upgrade one node, we'll have to upgrade them all. So let's get to it and flash some ROMs! Good luck and no bricks!
