 # Changelog
 
+## 3.0.0
+
+* Update `hyper` dependency to `1.0`. This is considered a breaking change because we expose the ability to
+    construct your own `AsyncRobot` using a custom `hyper::Client`, which was [removed in hyper v1.0](https://hyper.rs/guides/1/upgrading/).
+    The *Client* functionality is still available in the spin-off crate [hyper-util](https://github.com/hyperium/hyper-util),
+    which is also what `hrobot-rs` uses now.
+* Switch to using the rustls built-in webpki roots by default, instead of native roots. This is potentially a breaking change,
+    but in all likelihood, this won't impact you unless you're behind an intercepting firewall man-in-the-middling your traffic.
+    If you need to override this behaviour, see [AsyncRobot::new](https://docs.rs/hrobot/3.0.0/hrobot/struct.AsyncRobot.html#method.new)
+    for information about providing your own customized hyper client.
+* Update `serial_test` dependency to v3.0.0
+
 ## 2.0.0
 
 * Replace Decimal export with rust_decimal re-export.
