Because of the popularity of the platform, many people are looking for TF-A releases in the GitHub mirror at https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/.
However, even though v2.2 was released 11 days ago as per https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/, the GitHub repo still hasn't been updated to create a new v2.2 tag as well as a new GitHub release (https://github.com/ARM-software/arm-trusted-firmware/releases). The last "official" release there is still v2.1.
Can you please make sure that tags and new releases get applied to GitHub on release day? If not, I feel that a lot of people, as was the case for myself until I decided to look at git.trustedfirmware.org, will be very confused as to why there exist what looks like release commits for v2.2 on GitHub, yet no official tag for it or release artefacts.
