| 10 | +## New Functionality |
| 11 | + |
| 12 | +* **Extreme Networks EXOS** is supported as a Vagrant box or containerlab node with OSPF, VLAN, and VRRP configuration (by [Seb d'Argoeuves](https://github.com/sdargoeuves)). |
| 13 | +* The new [**bgp.advertise**](bgp-advertise-prefix) node attribute allows you to advertise networks in the IP routing table into BGP. It’s supported on most platforms. |
| 14 | +* The **bgp.originate** attribute is now [dual-stack and VRF-aware](bgp-advertise-prefix), allowing you to originate IPv4 and IPv6 prefixes into per-VRF BGP instances. |
| 15 | +* Static routes (including VRF and discard routes) are now supported on **Nexus OS**, **Nokia SR OS**, **Nokia SR Linux**, and **OpenBSD**. |
| 16 | +* **EVPN/VXLAN-over-IPv6** is now supported on **FRRouting**. |
| 17 | +* **BIRD** now supports [OSPF area parameters](plugin-ospf-areas). |
| 18 | +* **Junos** now supports BGP confederations and [route import](routing_import) into global and VRF BGP instances. |
| 19 | + |
| 20 | +**Minor improvements** |
| 21 | + |
| 22 | +* **EVPN control-plane-only nodes** (route reflectors) can now be configured for EVPN/VXLAN running over IPv6. |
| 23 | +* New *devices* [**netlab report**](netlab-report): nodes, node IDs, devices, and images — a quick summary of all nodes in the lab topology. |
| 24 | +* The **netlab show modules** command now splits module support tables into groups and multiple tables for better readability. |
| 25 | + |

| 76 | + |
| 77 | +Cisco IOS XR: |

| 79 | +* IOS XRd is fully tested and supported |
| 80 | + |
| 81 | +Dell OS10: |
| 82 | +* Dell OS10 needs the "normalize" step to shut down layer-2 interfaces in VLAN 1 |
| 83 | + |
| 84 | +FortiOS: |

| 101 | +## Potentially Breaking Changes |
| 102 | + |
| 103 | +We had to make a few changes to support the changed **bgp.originate** attribute and the new **bgp.advertise** attribute. There should be no impact unless you modified the _netlab_ device configuration templates. |
| 104 | + |
| 105 | +* The **bgp.originate** attribute is no longer present in the device data when the device supports *discard* static routes. When needed, _netlab_ adds entries to the **routing.static** list to create the routing table prefixes needed for BGP prefix origination and auto-enables the *routing* module. |
| 106 | +* We had to change the chains of Junos policies in global and VRF BGP instances. |
