<p>Dear BIRD users,</p>
<p>we are releasing BIRD versions 3.2.0 and 2.18.</p>
<p>We have implemented BGP dynamic onlink/unnumbered and
link-local
connection scenarios and fixed various behavior bugs in
reconfiguration.
Also, AS Sets in AS Paths are now considered malformed by
default.</p>
<p>For BIRD 3.2.0, we have split back the <code>igp_metric</code>
attribute so that now you may find also <code>local_metric</code>
where
applicable. There was a confusion in BIRD 3.0 and 3.1 arising
from two
distinct attributes in BIRD 2 named the same in the code, and me
not
understanding what Santiago was telling me about that. More on
that in
updated 3.2 documentation.</p>
<p>We have done various minor updates, e.g. flags in RAdv (both
versions), fixed a RIP non-determinism (v3) and additional CLI
configuration bugs.</p>
<p>There have been some more core reworks, removing some more
performance chokepoints.</p>
<p>Both versions also include all relevant fixes applied for 3.1.5
and
2.17.3.</p>
<p>Considering unfinished work, we also have several Babel patches
pending which we failed again to review in time to merge into
2.18.
We’ll do them as soon as possible. Also, in BIRD 3.x, the “show
route
for” displays all covering routes instead of just the longest
prefix
match. We’re working on a fix but it’s quite a can of worms.</p>
<p>Officially supported versions are now:</p>
<ul>
<li>3.2.0 and 2.18 until 6 months after 3.3.0 and 2.19 get
released</li>
<li>LTS 3.1.x and 2.17.x, expected to track Debian Trixie</li>
</ul>
<p>The DEB packages in pkg.labs.nic.cz are already there, and RPMs
will
come soon. Please note that the upstream DEBs weren’t built
directly
from the tagged commit but from the <code>release-v2.18</code>
and
<code>release-v3.2</code> branch because of our current CI
limitations.
We’ll fix that for later versions.</p>
<p>Happy new year!<br>
Maria and the BIRD Team</p>
<p>–<br>

<p>After upgrade we spotted small regression with AS-SETs in both
2.18 and 3.2:</p>
