26 Notes:
27
28 Export of routes to RS EBGP (route server) sessions from other sources than
29 RS EBGP sessions was changed that ASN is no longer prepended to BGP_PATH in
30 that case. The change does not affect regular BGP configurations or regular
31 route servers that have only RS EBGP peers.
32
33 For BGP route servers and route reflectors, the default value of option
34 'next hop keep' was changed to a more appropriate value.
35
36 Attributes for OSPF and Babel metrics are no longer reset when exported to
37 these protocols and could be set anywhere in BIRD. As a result, OSPF metric is
38 kept when a route is reannounced between OSPF instances. Also, when route is
39 exported to OSPF with both ospf_metric1 and ospf_metric2 attributes it is now
40 propagated as OSPF-E2 route instead of as OSPF-E1 route.
41
42 Compiling BIRD with --enable-debug no longer automatically activates debug
43 mode (-d option) nor local mode (-l option). Also, debug mode with output to
44 file (-D option) no longer not forces foreground mode (-f option).
45
46 The configure script now uses standard option --runstatedir, the old option
47 --with-runtimedir is deprecated.

116 configuration examples. Some options were removed/replaced.
