(release-26.08-breaking)=
## Breaking changes

* We enabled the [Transparent Management _containerlab_ feature](https://containerlab.dev/manual/vrnetlab/#management-interface) on vrnetlab-based devices supporting it in July 2026. This change should not impact older containers, but will change the management IPv4 address on virtual machines running within some newly-built containers from 10.0.0.15 (default management IPv4 address) to the outside (container) management IPv4 address.
* We switched to [sudo-less *containerlab* operation](https://containerlab.dev/install/#sudo-less-operation). If your containerlab-based labs fail to start, check whether your username is in the `clab_admins` group with the `groups` command. To add your username to that group, use:

```
sudo usermod -aG clab_admins $USER
newgrp clab_admins
```
