OpenBGPD 8.8

• Improve default multiproto capability announcement selection. The default MP capability is only set if no other capability is configured on the neighbor.
• The reject as-set configuration option now defaults to yes. Route announcements with AS_SET segments in the AS_PATH Attribute will be rejected. See draft-ietf-idr-deprecate-as-set-confed-set for more information.
• The RFC 8654 Extended Message configuration changed from announce extended (yes|no|enforce) to announce extended message (yes|no|enforce).
• RFC 8950 - Extended nexthop encoding support in the RIB.
• Preliminary support for EVPN in the RIB.
• When transparent-as yes is set, well-known BGP communities are passed on according to RFC 7947. This means that IX Route Servers transparently pass through NO_EXPORT, NO_ADVERTISE, etc.
• Fix an error introduced in the previous release that prevented sessions from staying down.
• Fix add-path send support using best, ecmp, or as-wide-best mode which was not working correctly in the previous release.
• Fix FIB handling on FreeBSD when an interface is destroyed.
• Make the example bgpd.conf work out of the box with 4byte ASN.
