## New Functionality

* Support for [Kubernetes (KinD) clusters](plugin-kind) based on work by [@wnagele](https://github.com/wnagele)
* Layer-2 EVPN/VXLAN support on Cat8000v, IOL, IOLL2
* Containers can be [configured with Linux scripts or *containerlab* startup-config parameter](platform-config-mode) instead of with an Ansible playbook.
* **[netlab graph](netlab-graph)** command can create graphs from a subset of nodes or links
* You can specify the parameters of core links in the **[fabric](plugin-fabric)** plugin
* "Are the SSH servers ready?" tests are executed directly in **netlab initial**, resulting in reduced Ansible-generated clutter.
* OSPFv3 reports

**Minor improvements**

* **[netlab status](netlab-status)** command can generate results in JSON or YAML format
* The **netlab api** command returns the JSON-formatted results of the **netlab status** command in `/status` GET request
* Use JSON files for Ansible group/host variables ([more](release-26.02-breaking))
* **netlab libvirt package** command can build custom Vagrant boxes (used for FRRouting boxes)

## New Device Features

Arista EOS:
* Arista cEOS can be configured with Linux scripts

Aruba CX:
* Aruba CX containers can be configured with *containerlab* partial startup configuration

Cisco IOS:
* IOSv/IOS-XE/IOL containers can be configured with *containerlab* partial startup configuration
* Layer-2 EVPN/VXLAN support on Cat8000v, IOL, IOLL2

Dell OS10:
* Dell OS10 containers can be configured with *containerlab* partial startup configuration

Linux:
* Containers can be configured with the **docker exec** command that executes Linux scripts (skipping the Ansible playbooks)

FRRouting:
* FRRouting containers are configured with Linux scripts
* You can use the **netlab libvirt package** command to build a custom Vagrant box with a preinstalled FRRouting package
* The custom Vagrant box can have the management VRF.

Junos:
* Junos containers can be configured with *containerlab* partial startup configuration

## Fixes in Configuration Templates

Bird:
* Reduced BGP connect/retry/hold timers
* BFD configuration uses its own configuration template

Cisco IOS/IOS-XE:
* Explicit **exit** from VRF BGP configuration (needed to have SRv6 configuration in the same startup-config)
* Cisco IOS/XE devices use a shared VXLAN configuration template

Cisco IOSvL2:
* _netlab_ sets the correct *containerlab* node *type* to influence the generation of initial configuration.
* The *containerlab* image name has been changed to reflect the latest image tag format used by *vrnetlab*
* Use correct interface variable in switchport normalization template (#3056)

Cumulus Linux NVUE:
* Fixed OSPFv2 area configuration template

Dell OS10:
* Cleanup device readiness check

FRRouting:
* Leave *zebra* to configure IP addresses on VLAN interfaces
* Load the MPLS kernel module in the FRR virtual machine

Linux:
* Control IP forwarding with the **netlab_ip_forwarding** variable (needed for KinD clusters)

RouterOS7:
* Set VLAN interface MTU/description
* Fix BGP/VRF/session/origination errors

SR Linux:
* Use SCP to copy the reloaded configuration to the device

VyOS:
* The shared "setup vbash" code has been removed from VyOS configuration templates and is now added during configuration deployment

(release-26.02-breaking)=
## Breaking changes

* The Ansible inventory files (apart from `hosts.yml`) are created in JSON format by default. If you need YAML-formatted inventory files, set the **defaults.outputs.ansible.filetype** [topology default](topo-defaults) to `yaml` or `yml` (depending on the desired file type).
