First:

1. Are there any confirmed issues with 1.2.1?
2. Are there any reconfig steps that need to done after upgrading?

Second:

Quote from 1F post re: 1.2

“The next firmware version of the software, 2.0 is a major software revision. What do we mean by ‘major’? Visually, and functionally, it will look and work very much the same as our current firmware (1.2). However, it’s underlying programing is moving to 64bit architecture, which means major, under the hood, work. What does moving to 64 bit mean? In simplified terms, it allows us to change from the current older raspberry pi 3b computer module that’s inside our controller today to the raspberry pi 4 computer module.”

What does that mean for all of the current Buildbotics users? Are we stuck with 1.2.1 forever? Or will there be an upgrade path for us, either a new module to put in the controller, or a complete new box?
