+## [0.1.20] - 2026-04-17
+
+### Added
+- Cross-platform packaging smoke tests in `ci/smoke/` that install the built wheel on
+  ubuntu, macos-14, macos-13, and windows-latest before publish, plus a post-publish
+  registry smoke. Publish is gated on all-platform smoke success.
+
+### Changed
+- Pinned `manylinux_2_28` with an explicit `python3.12` interpreter for the Linux wheel
+  build (upstream `manylinux: auto` regressed).
