## New Functionality

* **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)).
* 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.
* 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.
* Static routes (including VRF and discard routes) are now supported on **Nexus OS**, **Nokia SR OS**, **Nokia SR Linux**, and **OpenBSD**.
* **FortiOS** now supports static routing with discard routes (by [Aleksey Popov](https://github.com/a-v-popov)).
* **EVPN/VXLAN-over-IPv6** is now supported on **FRRouting**.
* **BIRD** now supports [OSPF area parameters](plugin-ospf-areas).
* **Junos** now supports BGP confederations and [route import](routing_import) into global and VRF BGP instances.

**Minor improvements**

* **EVPN control-plane-only nodes** (route reflectors) can now be configured for EVPN/VXLAN running over IPv6.
* New *devices* [**netlab report**](netlab-report): nodes, node IDs, devices, and images — a quick summary of all nodes in the lab topology.
* The **netlab show modules** command now splits module support tables into groups and multiple tables for better readability.

(release-26.04-breaking)=
## Potentially Breaking Changes

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.

* 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.
* We had to change the chains of Junos policies in global and VRF BGP instances.
