 # Changelog for network-wait
 
+## 0.2.0
+
+- Add `Network.Wait.Redis` module with functions to wait for Redis servers to become ready to accept connections. This module and its dependency on `hedis` are not enabled by default. The `network-wait:redis` flag must be enabled for this package's Redis support.
+- Generalise the `recoveringWith` function to allow it to return the result of a computation.
+- The functions for TCP/Sockets now return the `Socket` if they are successful.
+- The functions for PostgreSQL now return the `Connection` if they are successful.
+
