 +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: Keepalive time scaling
 +  o BGP: New 'min hold time' and 'min keepalive time' options
 +  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
 +
 +  Notes:
 +
 +  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
 +  released.
 +
 +
 +Version 2.0.10 (2022-06-16)
 +  o BGP performance improvements
 +  o BFD: New 'strict bind' option
 +  o RPKI: VRF support
 +  o Allow use of 240.0.0.0/4 as a private range
 +  o BIRD client uses exit status to report errors
 +  o Important bugfixes
 +
 +Version 2.0.9 (2022-02-09)
 +  o BGP: Flowspec validation procedure
 +  o Babel: MAC authentication support
 +  o Routing table configuration blocks
 +  o Optional prefix trie in routing table for faster LPM/interval queries
 +  o CLI: New 'show route in <prefix>' command
 +  o Filter: Faster (16-way) prefix sets
 +  o Filter: MPLS label route attribute
 +  o Filter: Operators to pick community components
 +  o Filter: Operators to find minimum and maximum element of lists
 +  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
 +
 +  Notes:
 +
 +  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
 +  filtering.
 +
 +
+ Version 3.0-alpha0 (2022-02-07)
+   o Removal of fixed protocol-specific route attributes
+   o Asynchronous route export
+   o Explicit table import / export hooks
+   o Partially lockless route attribute cache
+   o Thread-safe resource management
+   o Thread-safe interface notifications
+   o Thread-safe protocol API
+   o Adoption of BFD IO loop for general use
+   o Parallel Pipe protocol
+   o Parallel RPKI protocol
+   o Parallel BGP protocol
+   o Lots of refactoring
+   o Bugfixes and improvements as they came along
+ 
++
  Version 2.0.8 (2021-03-18)
    o Automatic channel reloads based on RPKI changes
    o Multiple static routes with the same network
