 # Release Notes
 
+## v1.15.2
+
+* Fixed a bug that caused a thread leak in the dhcp-proxy for each started container. ([#811](https://github.com/containers/netavark/issues/811))
+* Fixed a bug which printed bogus errors when the dhcp-proxy was run with an activity timeout of 0. ([#1262](https://github.com/containers/netavark/issues/1262))
+
 ## v1.15.1
 
 * Fixed a regression that caused container name lookups to get the wrong ip address when the host's search domain responded for the same name. ([containers/podman#26198](https://github.com/containers/podman/issues/26198))
