This packet contains firmware version information. majorVersion changes may introduce serious incompatibilities.
minorVersion changes may add or modify functionality, but maintain backward compatibility with previous minor
versions. patch level changes reflect bug fixes and internal modifications with little effect on the user. The build
stage is one of the following: 0=release candidate, 1=development, 2=alpha, 3=beta.
The buildNumber is incremented with each engineering firmware build. The buildNumber and stage for released
firmware are both zero. The final beta candidate is v.w.x.3.y, which is changed to v.w.x.0.1 to create the first release
candidate. The last release candidate is v.w.x.0.z, which is changed to v.w.x.0.0 for release.
