* Implement a more robust IPC system between the launcher and client * Clippy fix and cargo fmt * Switch to cached JsonReader with LENIENT parsing to avoid race conditions * Make RPC send messages in lines * Try to bind to either IPv4 or IPv6 and communicate version * Move message handling into a separate function to avoid too much code in a macro
