For GIT, the repo at https://cgit.freedesktop.org/mesa/mesa/ ; I don't see mesa 18.1.2 tagged but it seems to be officially announced.
Seems the tag exists at https://gitlab.freedesktop.org/mesa/mesa/tags/mesa-18.1.2 so likely the synchronization does nto copy over new tags?
Tag is definitely there. Closing
The tag is there: https://cgit.freedesktop.org/mesa/mesa/refs/tags We were failing to push tags for a while but it was fixed some time ago.
