+# Release Notes v2.0.4
+
+## Fixes
+- Reworked the migration execution endpoint to stream SQL files via stdin instead of relying on chained shell commands, which broke on Podman/Docker setups and led to pattern-matching errors for some files.
+- Added a default `CONTAINER_RUNTIME` setting so the endpoint knows whether to run `docker` or `podman` when the env var is not provided.
