+ version, therefore there are compatibility issues in OSPF NSSA areas between
+ this and previous version.
+
+
+Version 2.0.4 (2019-02-27)

+
+ Notes:
+
+ 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.

+ o Default EBGP Route Propagation Behavior without Policies (RFC 8212)

+ explicit configuration of import and export policies.
+

+ o Integrated IPv4 + IPv6 design
+ o Support for MPLS next hops
+ o Support for VPNv4 and VPNv6 networks

+ import, export, ...) are now channel options. See doc/bird.conf.example2 for
