# Changelog
## 2026-02-19 - 4.0.0 - BREAKING CHANGE(remoteingress-core)
add cancellation tokens and cooperative shutdown; switch event channels to bounded mpsc and improve cleanup
- Introduce tokio-util::sync::CancellationToken for hub/edge and per-connection/stream cancellation, enabling cooperative shutdown of spawned tasks.
- Replace unbounded mpsc channels with bounded mpsc::channel(1024) and switch from UnboundedSender/Receiver to Sender/Receiver; use try_send where non-blocking sends are appropriate.
- Wire cancellation tokens through edge and hub codepaths: child tokens per connection, per-port, per-stream; cancel tokens in stop() and Drop impls to ensure deterministic task termination and cleanup.
- Reset stream id counters and clear listener state on reconnect; improved error handling around accept/read loops using tokio::select! and cancellation checks.
- Update Cargo.toml and Cargo.lock to add tokio-util (and related futures entries) as dependencies.
- BREAKING: public API/types changed — take_event_rx return types and event_tx/event_rx fields now use bounded mpsc::Sender/mpsc::Receiver instead of the unbounded variants; callers must adapt to the new types and bounded behavior.
