+# Release 0.13.0
+:material-calendar: 2021-04-13
+
+## Cisco CSR1000v support
+Added support for Cisco CSR1000v system via [`vr-csr`](../manual/kinds/vr-csr.md) kind.
+
+## RouterOS support
+With [`vr-ros`](../manual/kinds/vr-ros.md) kind added support for Mikrotik RouterOS system.
+
+## Arista cEOS improvements
+This patch release brings the following improvements to Arista cEOS:
+
+1. Arista Ma0 MAC address is now having Arista OUI, instead of docker generated local MAC. Additionally, [System MAC address is now generated](https://github.com/srl-labs/containerlab/pull/362) as the next MAC address from Ma0 interface.
+2. ETBA environment variable is [set to `4`](https://github.com/srl-labs/containerlab/pull/360), from its original value of `1`.
+3. Default cEOS configuration now has the following config line to allow for enhanced BGP daemon to run on startup:
+    ```
+    service routing protocols model multi-agent
+    ```
+
+## Attachments to management network
+With a new reserved endpoint definition it is now [possible](../manual/network.md#additional-connections-to-management-network) to attach data interface of a node to the management network.
+
+
+## Miscellaneous
+* a warning message will be displayed if container host has less than 1GB of free memory
+* a lab won't deploy if a user specified `eth0` interface in the links section as this is not a possible configuration
+* Now it is possible to safely use `-` (dashes) in lab name.
