 ## [Unreleased]
 
+## [1.2.1] - 2026-09-01
+
+First release published to PyPI. The package itself is byte-identical to 1.2.0 —
+`src/` and `pyproject.toml` are unchanged — so there is nothing to upgrade for if you
+are already running 1.2.0 from source.

+### Changed
+
+- The release workflow gained a `workflow_dispatch` trigger, so a publish can be
+  retried without recreating the GitHub Release. Both entry points share the same
+  tag/version guard.
+- Checkout in the release build is pinned to the tag being released rather than
+  defaulting to the branch.
