+**[v2.12.2: Perchance to Stream](https://github.com/jlowin/fastmcp/releases/tag/v2.12.2)**
+
+This is a hotfix for a bug where the `streamable-http` transport was not recognized as a valid option in `fastmcp.json` configuration files, despite being supported by the CLI. This resulted in a parsing error when the CLI arguments were merged against the configuration spec.
