Making a release
Check for "foundational" software upgrades
Mainly Trusted Firmware-A. If a new release was made, upgrade it.
At release time
We have one commit with the released name/version un-suffixed.
support/release.sh script to update the version numbers, make the
commits and tag accordingly.
After the release
Not strictly needed, but upgrading Nixpkgs frequently enough helps us stay on top of updates for dependencies.
Updating the pinned Nixpkgs after the release ensures we're testing the change for the longest time possible.
