I was consulting the documentation for Electron Firmware 7.0 on github and was wondering how to assess what changes or feature improvements were added over Electron Firmware 6.4
Here was the link I was using.
What’s the best way to figure out what the improvements are?
But as @Moors7 noted, you should also read the release notes in this thread to know if there are any special upgrade / downgrade procedures: Particle Firmware Updates Thread
