+## [v0.16.2] - May 21, 2026
+
+### Bugfixes
+- Resolve nested calculated channel references when fetching calculated channels so expressions that depend on other calculated channels evaluate correctly. ([#580](https://github.com/sift-stack/sift/pull/580))
+- Infer the parquet time column for integer timestamp columns in data imports so files with integer epoch time columns no longer fail detection. ([#582](https://github.com/sift-stack/sift/pull/582))
+
+## [v0.16.1] - May 19, 2026
+
+### Bugfixes
+- Replace the POSIX-only `fcntl.flock` call in the test-results log with a cross-platform `filelock.FileLock` so importing `sift_client` no longer fails on Windows. ([#574](https://github.com/sift-stack/sift/pull/574))
