+
+Fetch the latest released versions of:
+* PyPI package `kernel`
+* npm package `@onkernel/sdk`
+
+and update every version constraint inside:
+* templates/python/*/pyproject.toml  -> "kernel>=<latest>"
+* templates/typescript/*/package.json -> "@onkernel/sdk": ">=<latest>"
+
+If a file is modified, it is overwritten in-place. The script exits with code 0
+whether or not modifications were required. However, it prints a summary that is
+useful inside CI to decide if a commit is necessary.
