See troubleshooting.md for a troubleshooting guide.

Backwards compatibility

See mcpgodebug.md for a list of backwards incompatible behavior changes and description how they can be temporarily undone.

Rough edges

See rough_edges.md for a list of rough edges or API oversights that can't be addressed due to our compatibility promise. We'll revisit these if/when we move to a v2 of the SDK.
