+### Fixed
+- No source code changes. `v1.2.0` was originally tagged before its corresponding pull request was merged into
+  `main`, so the published tag pointed to the pre-merge commit instead of the datacenter/worker id split described
+  in its release notes. The tag was corrected on GitHub, but JitPack had already cached a build under the
+  `v1.2.0` name pointing to the old commit. This release is a clean re-tag of the same `v1.2.0` code under a new
+  version, so JitPack builds it fresh. Depend on `v1.2.1` (not `v1.2.0`) to get the corrected code.
