+* Changes in Quagga 0.99.23
+
+Known issues:
+- [bgpd] setting an extcommunity in a route map on a route that already has
+ an extcommunity attribute will cause bgpd to crash. This issue will be
+ fixed in a followup minor release.
+
+User-visible changes:
+- [lib] Performance enhancements on hashes and timers.
+- [bgpd] New feature: iBGP TTL security.
+- [bgpd] New feature: relaxed bestpath criteria for multipath and improved
+ display of multipath routes in "show ip bgp". Scripts parsing this output
+ may need to be updated.
+- [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate
+ IPv4 nexthop by looking at the interface.
+- [ospf6d] A large amount of changes has been merged for ospf6d. Careful
+ evaluation prior to deployment is recommended.
+- [zebra] Recursive route support has been overhauled. Scripts parsing
+ "show ip route" output may need adaptation.
+- [zebra] IPv6 address management has been improved regarding tentative
+ addresses. This is visible in that a freshly configured address will not
+ immediately be marked as usable.
+- [*] a lot of bugs have been fixed, please refer to the git log
+
