Dear BIRD Users,

it’s been quite a while but we have released BIRD versions 3.2.1, 3.1.6, 2.18.1, and 2.17.4. Yes, all of these. We got a lot of bugreports, not only through the users list but also privately. Thank you all so much for them.

The download link is, as always: https://bird.nic.cz/get-bird/

There is the ASPA fix you are waiting for, fixing broken downstream validation. Thanks for reporting and contributing; that was a stupid mistake. More on that hopefully at RIPE 92 in Edinburgh.

Also in all released versions, there are:

• bugfixes for krt_congctl attribute handling
• logrotate file size limit lower bound (16k)
• a bunch of CI updates

For LTS 3.1.6 and 2.17.4, we also included fixes of BGP reconfiguration which are already in 3.2.x and 2.18.x.

And then there is much more fixed in BIRD 3 alone:

• logrotate crash fix
• ROA check crash fix (strangely manifesting mostly when manipulating ASPA checks in filters)
• graceful recovery fix (now it doesn’t crash when recovery is done)
• BGP route refresh request fix (now it works even after session flap)
• BMP (now it actually sends routes)
• rare pipe collision bug
• BGP dynamic instance crash fix (3.2.1 only)
• keyword redefinition allowed again (3.2.1 only)

We did what we could to keep track of everything. If you reported something between 3.2 and 2.18 was released, and March 31, 2026, it should be included in this release. Yet, we may have missed something, and also while we did our best to cover all reported bugs by automatic tests, we would still love if you found some time to check that on your side and report both positive and negative outcomes.

Also it looks like there are already some new bugreports. We’ll try to pick them up as soon as possible.

In parallel, we are also preparing a next minor (feature) release. Although the only merged feature is now RAdv neighbor discovery with BGP autoconnect, we also expect to include the oz-evpn branch (for both BIRD 2 and 3) and a bunch of BGP export memory optimization updates for BIRD 3.

Thank you all again for all your reports, contributions, patience and efforts.

Happy routing!
Maria and the BIRD Team
