Repositories like golang/x/sys should be updated to the tip of their master. Maybe there is a bug in the releaser tool?

[JamyDev]

Yeah I was surprised it didn't change anything else. Can you try and run it, maybe I don't have the permissions to run it properly.

[JamyDev]

Marking as draft until I can figure out the issues for the updater tool.
