 ## Unreleased
 
+## 0.3 - 2024-01-04
+
+- Added `ReadReady` and `WriteReady` impls on `TcpSocket`.
 - Avoid never resolving `TcpIo::read` when the output buffer is empty.
-- Update to `smoltcp` git.
+- Update to `smoltcp` v0.11.
 - Forward constants from `smoltcp` in DNS query results so changing DNS result size in `smoltcp` properly propagates.
+- Removed the nightly feature.
 
 ## 0.2.1 - 2023-10-31
