o OSPF: Fix regression in handling PtP links
o RPKI: Handle connection resets properly
o Static: Reject invalid combination of options
o Fix builds with limited set of protocols
Version 2.15 (2024-03-10)

Version 2.14 (2023-10-06)
o MPLS subsystem
o BGP: Access to unknown route attributes
o RAdv: Custom options
o Babel: RTT metric extension
o BMP: Refactored route monitoring
o BMP: Multiple instances of BMP protocol
o BMP: Both pre-policy and post-policy monitoring
o Experimental route aggregation
o Filter: Method framework
o Filter: Functions have return type statements
o Filter: New bytestring data type
o Kernel: Option to learn kernel routes
o Many bugfixes and improvements
User-defined filter functions that return values now should have return type
statements. We still accept functions without such statement, if they could be
properly typed.
For loops allowed to use both existing iterator variables or ones defined in
the for statement. We no longer support the first case, all iterator variables
must be defined in the for statement (e.g. 'for int i in bgp_path ...').
Due to oversight, VRF interfaces were not included in respective VRFs, this is
fixed now.
Version 2.13.1 (2023-06-23)
o BGP: Fix role check when no capability option is present
o Filter: Fixed segfault when a case option had an empty block
This is a bugfix version.

o Babel: IPv4 via IPv6 extension (RFC 9229)
o Babel: Improve authentication on lossy networks
o BGP: New 'allow bgp_med' option
o BSD: Support for IPv4 routes with IPv6 nexthop on FreeBSD
o Experimental BMP protocol implementation
o Important bugfixes
We changed versioning scheme from <epoch>.<major>.<minor> to more common
<major>.<minor>.<patch> . From now on, you may expect that BIRD 2.13.x will be
strictly only fixing bugs found in 2.13, whereas BIRD 2.14 will also contain
new features.
This BIRD version contains an alpha release of BMP protocol implementation.
It is not ready for production usage and therefore it is not compiled by
default and have to be enabled during installation.
Version 2.0.12 (2023-01-23)
o Filter: New 'onlink' route attribute
o Compile-time option to use 4-way tries instead of 16-way ones
o BSD: Support for kernel route metric and other improvements
o Important bugfixes
Version 2.0.11 (2022-11-12)
o BGP roles (RFC 9234)

o BGP: New 'next hop prefer global' option
o Filter: For loops and direct recursion
o Filter: Mixed declarations of local variables
o Filter: Improved static type checks
o Filter: Literal [] for empty set
o Linux: Netlink KRT improvements
o BSD: Experimental support for Netlink API
o Memory management improvements
o Many bugfixes
In contrast to prior versions, configured keepalive time in BGP now scales
with negotiated hold time to maintain proportion between the keepalive time
and the hold time.
The Linux KRT was updated to use the recent API for IPv6 ECMP routes instead
of the legacy one. Consequently, the Linux versions older than 4.11 are no
longer supported, at least for IPv6 ECMP routes. Also, routing table scanning
now runs separately for each table to avoid congestion.
There is a minor change in recursive next hop processing. Previously,
recursive next hop must be resolved through a non-recursive route, now it must
be resolved through a prefix where both the best route and all routes with the
same preference (as the best route) are non-recursive. The old behavior might
lead in some corner cases to an infinite loop of recursive next hop resolution
due to a priority inversion.
There is a minor change in the 'configure undo' command, it is no longer
available after failed reconfiguration, as the old configuration is already
Version 2.0.10 (2022-06-16)
o BGP performance improvements
o BFD: New 'strict bind' option
o RPKI: VRF support

o BGP: New 'free bind' option
o BGP: Log route updates that were changed to withdraws
o BGP: Improved 'invalid next hop' error reporting
o OSPF: Allow ifaces with host address as unnumbered PtP or PtMP ifaces
o OSPF: All packets on PtP networks should be sent to AllSPFRouters address
o Scripts for apkg-powered upstream packaging for deb and rpm
o Support for Blake2s and Blake2b hash functions
o Security keys / passwords can be entered in hexadecimal digits
o Memory statistics split into Effective and Overhead
o Linux: New option 'netlink rx buffer' to specify netlink socket buffer size
o BSD: Assume onlink flag on ifaces with only host addresses
o Many bugfixes
For OSPF on PtP network, BIRD now sends all packets to multicast AllSPFRouters
address (as required in RFC 2328 8.1). This likely breaks setups with multiple
neighbors on a network configured as PtP, which worked in previous versions.
Such links should be configured as PtMP.
Since Linux 5.3, netlink socket can be flooded by route cache entries during
route table scan. This version mitigates that issue by using strict netlink
Version 2.0.8 (2021-03-18)

o BFD: Per-peer session options
o RPKI: Allow build without libSSH
o RPKI: New 'ignore max length' option
o OSPF: Redesign of handling of unnumbered PtPs
o OSPF: Allow key id 0 in authentication
o Babel: Use onlink flag for routes with unreachable next hop
o Many bugfixes
Automatic channel reloads based on RPKI changes are enabled by default,
but require import table enabled when used in BGP import filter.
BIRD now uses bitmaps to keep track of exported routes instead of
re-evaluation of export filters. That should improve speed and accuracy in
route export handling during reconfiguration, but takes some more memory.
Per-channel debug logging and some CLI commands (like 'show ospf neighbors')
defaulting to all protocol instances lead to some minor changes in log and
CLI output. Caution is recommended when logs or CLI output are monitored by

o BGP: Promiscuous ASN mode
o BGP: Mandatory option for channels
o BFD: Support for VRFs
o Graceful restart command
o Redesigned filtering code
o Many bugfixes
Previous version introduced an error in handling of OSPF NSSA-LSA, causing
compatibility issues with proper implementations. The error is fixed in this
version, therefore there are compatibility issues in OSPF NSSA areas between
this and previous version.
Version 2.0.4 (2019-02-27)
o OSPF: Opaque LSAs (RFC 5250)
o OSPF: DN-bit handling (RFC 4576)

o Many bugfixes
Export of routes to RS EBGP (route server) sessions from other sources than
RS EBGP sessions was changed that ASN is no longer prepended to BGP_PATH in
that case. The change does not affect regular BGP configurations or regular
route servers that have only RS EBGP peers.
For BGP route servers and route reflectors, the default value of option
'next hop keep' was changed to a more appropriate value.
Attributes for OSPF and Babel metrics are no longer reset when exported to
these protocols and could be set anywhere in BIRD. As a result, OSPF metric is
kept when a route is reannounced between OSPF instances. Also, when route is
exported to OSPF with both ospf_metric1 and ospf_metric2 attributes it is now
propagated as OSPF-E2 route instead of as OSPF-E1 route.
Compiling BIRD with --enable-debug no longer automatically activates debug
mode (-d option) nor local mode (-l option). Also, debug mode with output to
file (-D option) no longer not forces foreground mode (-f option).
The configure script now uses standard option --runstatedir, the old option
--with-runtimedir is deprecated.
Version 2.0.2 (2018-03-22)
o Source-specific routing support for Linux kernel and Babel
o BGP: New option 'disable after cease'
o Filter: Allow silent filter execution
o Filter: Fixed stack overflow in BGP mask expressions.

o Linux MPLS kernel support
o Better handling of channels inherited from templates
o Default EBGP Route Propagation Behavior without Policies (RFC 8212)
