+## Version 0.9.0
+[Documentation for this release](https://metallb.universe.tf)
+
+New features:
+
+- Dramatically reduce dead node detection time when using Layer 2 mode. ([#527](https://github.com/metallb/metallb/pull/527)). Fixes [#298](https://github.com/metallb/metallb/issues/298).
+
+ This is improvement closes the linked long standing issue that has been a
+ common pain point for users using Layer 2 mode. This feature is enabled by
+ default.
+ You can disable it by:
+
+ * Changing the `speaker` `Daemonset` manifest and remove the `METALLB_ML_BIND_ADDR` environment variable
+
+ Also, you can verify the old method is being used by checking the `speaker`
+ log on startup to contain: `Not starting fast dead node detection (MemberList)`.
+ If not shown, the new fast node detection method is being used.
+- Allow spaces in address pool IP ranges. ([#499](https://github.com/metallb/metallb/issues/499))
+
+Action required:
+
+- Layer 2 users by default will use a new algorithm to detect dead nodes (time
+ is significantly reduced). If you want to continue with the old way, see the
+ New features section to see how to opt-out. If you find any problems with the
+ new algorithm, as usual, please open an issue.
+
+Bug fixes:
+
+- Allow kustomize to change namespace MetalLB runs. ([516](https://github.com/metallb/metallb/pull/516))
+- Fix layer2 not sending ARP messages when IP changes. ([#520](https://github.com/metallb/metallb/pull/520)). Fixes [#471](https://github.com/metallb/metallb/issues/471).
+- Fix to properly expose `address_total` Prometheus metric. ([518](https://github.com/metallb/metallb/pull/518))
+- Add note in installation process about `strictARP` when using `kube-proxy` in IPVS mode. ([507](https://github.com/metallb/metallb/pull/507))
+- Support older devices that might not support RFC4893. ([#491](https://github.com/metallb/metallb/pull/491))
