Dear BIRD users,

we are releasing BIRD versions 3.4.0 and 2.20.0. Both versions include all relevant fixes applied in versions 3.3.3, 3.2.4, 3.1.9, 2.19.3, 2.18.2 and 2.17.7. Downloads are possible at https://bird.nic.cz/get-bird/ and in our upstream repositories.

We have added the BGP channel option ignore otc to allow people apply this check manually instead. We have also added passive support for the EVPN ESI attribute.

We have added an option to create local-host routes from interface records via the Direct protocol, and a show radv interfaces CLI command.

This is mostly a minor minor release, and there are more things in progress.

Officially supported versions are now:

• 3.4.0 and 2.20.0 until 6 months after 3.5.0 and 2.21.0 get released
• 3.3.0 and 2.19.0 until end of April 2027
• 3.2.x and 2.18.x until end of November 2026
• LTS 3.1.x and 2.17.x tracking Debian Trixie

Also, on commercial note, we offer BIRD Support, so that you can get help with configuration, priority access to critical bug fixes, and better influence the overall development directions. It’s the users paying for these services, who keep the development running. More on that at our website: https://bird.nic.cz/commercial-services/

Happy routing! Maria and the BIRD Team
