+# Release 0.16
+:material-calendar: 2021-08-02
+
+!!!warning
+    This release adds a new way of writing containerlab hosts information into the `/etc/hosts` file.
+
+    Before upgrading to this release destroy all labs and ensure no stale entries are present in the `/etc/hosts` file, then do the upgrade.
+
+## Improved interfaces detection for vr-based nodes
+With the enhancements made by [@carlmontanari](https://github.com/carlmontanari) in vrnetlab and [@networkop](https://github.com/carlmontanari) in containerlab we improved the way vr-based nodes boot.
+
+The improvements are related to the way VMs inside the containers detect the presence of the dataplane interfaces. Starting with `hellt/vrnetlab v0.5.0` and `containerlab v0.16.0` the nodes will know exactly how many interfaces a user defined in the lab file, and therefore will wait for those interfaces to appear before booting the qemu VM.
+
+## Non-sequential interfaces for vr-based nodes
+Thanks to [@carlmontanari](https://github.com/carlmontanari) work in [vrnetlab#55](https://github.com/hellt/vrnetlab/pull/55) it is not possible to define nodes interfaces in a non-sequential way. This means, that now a user can define the links as follows:
+
+```yaml
+topology:
+  nodes:
+    sr1:
+      kind: vr-sros
+      image: vr-sros:21.5.R2
+
+    sr2:
+      kind: vr-sros
+      image: vr-sros:21.5.R2
+
+  links:
+    # sr1 port 3 is connected to sr2 port 5
+    - endpoints: ["sr1:eth3", "sr2:eth5"]
+```
+
+## New DNS entries format
+Containerlab [creates nodes DNS entries](../manual/network.md#dns) when the lab is deployed. In this release we improved the visual layout of those entries so they can be introspected easier.
+
+## User-defined Ansible groups
+A user can now specify an [extra ansible group](../manual/inventory.md#user-defined-groups) the node should be part of in addition to the default grouping by kind.
+
+## New node kinds
+[@carlmontanari](https://github.com/carlmontanari) added support for [Cisco Nexus 9000v](../manual/kinds/vr-n9kv.md) and [Palo Alto PAN](../manual/kinds/vr-pan.md) nodes.
+
+## Miscellaneous
+* IPv6 LLA is now enabled on veth interfaces [#551](https://github.com/srl-labs/containerlab/issues/551)
