+2021-06-29 Daniel Baumann <daniel.baumann@open-infrastructure.net>
+
+ * Releasing version 20210628.
+
+ * Backward incompatible changes:
+ - The networking integration on the container host depended on
+ ifupdown. Now, to support KVM as an additional backend
+ alongside systemd-nspawn in compute-tools, we're switching
+ in this version exclusively to openvswitch.
+ - Moving from ifupdown to openvswitch to manage the bridges
+ requires manual re-configuration of the networking stack on
+ the host, otherwise no container will continue to have network
+ access.
+ - Configuration examples for systemd-networkd (recommended) on the
+ host to use openvswitch are documented in HOST-SETUP.txt.
+
+ [ Simon Spöhel ]
+ * Using openvswitch instead of linux bridges.
+ * Updating documentation for openvswitch.
+
2021-06-28 Daniel Baumann <daniel.baumann@open-infrastructure.net>
* Releasing version 20210628.
