The pending Read the Docs builds are builds that were cancelled because there were no changes. They should be showing as skipped or successful. Maybe the issue related to this isn't actually fixed (I don't want to reference it directly in each of our changes because each mention shows up in the issue) or maybe there's something not quite right with our configuration.

Either way, this is ready for merging, once it's approved.
