# Release Notes

## v1.4.0
* Added network update command
* Corrected issue #491 to only teardown network forwarding when on complete teardown only
* Fixed some rust documentation

## v1.3.0
* Housekeep and code cleanup
* macvlan: remove tmp interface when name already used in netns
* Add support for route metrics
* netlink: return better error if ipv6 is disabled
* macvlan: fix name collision on hostns
* Ignore dns-enabled for macvlan (BZ2137320)

## v1.2.0
* Reworked how netavark calls aardvark
* Implemented locking when commiting
* Remove bridge only when no containers are attached
* Updated versions of libraries where possible

## v1.1.0
* Netavark is now capable of starting Aardvark on a port other than 53 (controlled by `dns_bind_port` in `containers.conf`). Firewall rules are added to ensure DNS still functions properly despite the port change.
* Added the ability to isolate networks. Networks with the isolate option set cannot communicate with other networks with the isolate option set.
* Improved the way Aardvark is launched to avoid potential race conditions where DNS would not be ready when containers were started.
* Fixed a bug where Aardvark could not be run in environments with a read-only `/proc` (e.g. inside a container).

## v1.0.3
* Updated dependenciess
* Simplified option parsing for bridge/macvlan
