serde-json-wasm patched a bug recently that causes deeply nested JSON to overflow the stack, which would cause a runtime error and prevent a contract from executing. this would only cause problems if someone submits an extremely nested JSON message in a proposal, which is unlikely and the user can avoid it, but it's still good to fix. no contracts are at risk of being bricked.
