(release-25.10)=
## New Functionality

* You can use [wildcards or regular expressions](groups-members) to specify group- or **[as_list](bgp-aslist)** ASN/RR members.
* New device: container version of Cisco 8000v emulator (running IOS XR)

(release-25.10-graph)=
**Graph Improvements**

* [Apply different styling](netlab-graph-topo-format) to VLAN access/trunk links in topology graphs
* Change the D2 node/edge styles to match Graphviz colors
* Enable custom node/link formatting with [**graph.format**](outputs-graph-link-node-attributes) and [**d2.format**](outputs-d2-link-node-attributes) node/link attributes
* Implement [node rank](outputs-graph-layout) in Graphviz graph definition files

**Other Minor Improvements**

* Implement select IGP parameters on loopback interfaces
* [Remove EBGP sessions](evpn-rp) with other PE-devices on EVPN-controlled VLANs
* Change management MAC address pool and netlab-generated device MAC addresses to locally-administered addresses
* Add '--debug: paths' option to help troubleshoot custom templates

## New Device Features

Arista EOS:
* Change default cEOS release to 4.34.2F

Cisco IOS:
* Change image names for Cisco IOSv L2 and Catalyst 8000v *vrnetlab* containers

Cisco IOS XR:
* Implement OSPFv2/v3 timers, passwords, and router priority

FortiOS:
* Use CD-ROM configuration to [build FortiOS Vagrant box](build-fortios)

OpenBSD:
* OSPFv2/v3 support

SR Linux:
* Change default release to 25.7.2

Junos vPTX:
* Support for [vJunosEVO release 24/25](caveats-vptx)

(release-25.10-device-fixes)=
## Fixes in Configuration Templates

Cisco IOS XR:
* Fix OSPFv2/v3 templates

SR Linux:
* Use Linux-style /etc/hosts files (#2677)

(release-25.10-breaking)=
## Breaking changes

* Junos vPTX (vJunosEVO) [needs a UEFI BIOS](caveats-vptx) starting with release 24. Unfortunately, that BIOS does not work with release 23. *netlab* uses UEFI BIOS to start vptx virtual machines; build a *vrnetlab* container if you'd like to run vPTX Junos release 23 or earlier.
* D2 graphs use the same colors as Graphviz graphs, making them a bit different from what they were before.
* The _netlab_-generated management MAC addresses were squatting on Cisco OUI. We changed the management MAC address pool to use locally-administered addresses with the CA:FE:00 OUI.
* _netlab_ removes EBGP sessions between EVPN PE-devices on EVPN-enabled VLANs. In most cases, that's the desired behavior. Use **evpn.domain** node parameter if this change impacts your design.
* The BGP graphs list nodes in peer-to-peer BGP sessions in the order specified in the **nodes** dictionary. This might change how Graphviz/D2 generates BGP graphs.
