 * **Telemetry validation**
     Coupling modern telemetry stacks with containerlab labs make a perfect fit for Telemetry use cases validation. Spin up a lab with containerized network functions with a telemetry on the side, and run comprehensive telemetry use cases.

+# Release 0.15
+:material-calendar: 2021-07-16
+
+!!!warning
+    This release adds a breaking change in the clab file schema. Starting from this release version, a path to a startup config file needs to be provided with `startup-config` key. Previously it was done with `config` key.  
+
+    Use `sed -i s/config:/startup-config:/g <topo-file>` script to auto-substitute the values in the `<topo-file>` file.
+
+## Ignite runtime support and Cumulus VX
+[@networkop](https://github.com/networkop) embarked on a journey of adding a [Cumulus VX](../manual/kinds/cvx.md) to containerlab, and he chose the doing-this-the-hard-way by running Cumulus VX as a container[^1]. To make that happen, he added a new `ignite` runtime that allows us to launch containers with custom kernels.
+
+With that work done, containerlab is now supporting a new kind - [`cvx`](../manual/kinds/cvx.md) - that defines the Cumulus VX NOS and that can run in [different modes](../manual/kinds/cvx.md#mode-of-operation)[^2].
+
+## Containerd runtime support
+[@steiler](https://github.com/steiler) added experimental support for `containerd` runtime. As the name implies, this makes it possible to run containerlab having only containerd installed and the necessary CNI plugins.
+
+Please bear in mind that not all containerlab features are available for containerd runtime, but the core feature set is there.
+
+To start containers with containerd runtime, the `--runtime | -r` global flag has been introduced.
+
+## The BIG refactoring
+With @karimra superpowers, containerlab has undergone a major refactoring of its code base. Now we have a strong and flexible foundation to build new features on top.
+
+This was the biggest architectural change since the beginning, so some rough edges might eventually show up, but we will iron them out.
+
+## Community
+We strive to support the growing containerlab community to the best of our abilities. While github discussions is a nice place to ask formulated questions sometimes it is really nice to have a chat with the community members.
+
+With that in mind we launched the containerlab's own [discord server](https://discord.gg/vAyddtaEV9) that all are welcome to join!
+
+## Miscellaneous
+* kind base configuration templates are now embedded in the code. This means that you can download containerlab binary from Releases and launch the labs, without doing the installation from packages.  
+    The reason you might want to do this is if you want to install containerlab on a system which doesn't have rpm/deb based package manager.  
+    Note, that the package-based installation is still the recommended way.
+* the `exec` command now has a [`--format`](../cmd/exec.md#format) flag that is capable of nicely handling the JSON outputs.
+* deployment of SR Linux nodes will now proceed even if license file is not present[^3]
+* a new [`--keep-mgmt-net`](../cmd/destroy.md#keep-mgmt-net) flag has been added to `destroy` command to prevent the management network deletion attempt
+* the MTU on the veth links created between the containers has been lowered to 9500 from its original 65000 value
+
+
+
+[^1]: as opposed to a VM-way by running Cumulus with [vrnetlab](../manual/vrnetlab.md)
+[^2]: both with `ignite` runtime or `docker` runtime
+[^3]: starting with SR Linux 21.3, the license file is optional
