# Changelog
## 2025-08-29 - 2.2.0 - feat(ipcclient)
Add clientOnly mode to prevent clients from auto-starting servers and improve registration/reconnect behavior
- Introduce a clientOnly option on transports and clients, and support SMARTIPC_CLIENT_ONLY=1 env override to prevent a client from auto-starting a server when connect() encounters ECONNREFUSED/ENOENT.
- Update UnixSocketTransport/TcpTransport connect behavior: if clientOnly (or env override) is enabled, reject connect with a descriptive error instead of starting a server (preserves backward compatibility when disabled).
- Make SmartIpc.waitForServer use clientOnly probing to avoid accidental server creation during readiness checks.
- Refactor IpcClient registration flow: extract attemptRegistrationInternal, set didRegisterOnce flag, and automatically re-register on reconnects when previously registered.
- Add and update tests to cover clientOnly behavior, SMARTIPC_CLIENT_ONLY env enforcement, temporary socket paths and automatic cleanup, and other reliability improvements.
- Update README with a new 'Client-Only Mode' section documenting the option, env override, and examples.
## 2025-08-28 - 2.1.3 - fix(classes.ipcchannel)
Normalize heartbeatThrowOnTimeout option parsing and allow registering 'heartbeatTimeout' via IpcChannel.on
