+### Fixed
+
+- Unquoted IPv6 bind hosts with trailing colons erroneously considered
+  unspecified addresses are now properly validated ([#5752]).
+
+  **NOTE:** the Docker healthcheck script now also doesn't interpret the `""`
+  value as unspecified address.
+- Incorrect `Content-Type` header value in `POST /control/version.json` and `GET
+  /control/dhcp/interfaces` HTTP APIs ([#5716]).
+- Provided bootstrap servers are now used to resolve the hostnames of plain
+  UDP/TCP upstream servers.
