I've likely made other errors.

tag v0.9.0 commit 8f35a5c0 2020-10-07

tag v0.10.0 commit a6b2180 2020-10-12

branch v1.9.0 commit 3ac3396 2021-05-17

tag v1.9.0 commit ada7f97b 2021-05-17

tag v1.10.0 commit 764fa9dae6 2021-06-23 origin/releases

I found it.  I have a local branch locally named v1.9.0 that contains commits on top of v1.10.0 .

I apparently merged something on top of my releases worktree and named it as an earlier version.

I try (some disappear) to take 24/7 terminal logs, so that may be reviewable if needed.
