56 Notes:
57
58 Export of routes to RS EBGP (route server) sessions from other sources than
59 RS EBGP sessions was changed that ASN is no longer prepended to BGP_PATH in
60 that case. The change does not affect regular BGP configurations or regular
61 route servers that have only RS EBGP peers.
62
63 For BGP route servers and route reflectors, the default value of option
64 'next hop keep' was changed to a more appropriate value.
65
66 Attributes for OSPF and Babel metrics are no longer reset when exported to
67 these protocols and could be set anywhere in BIRD. As a result, OSPF metric is
68 kept when a route is reannounced between OSPF instances. Also, when route is
69 exported to OSPF with both ospf_metric1 and ospf_metric2 attributes it is now
70 propagated as OSPF-E2 route instead of as OSPF-E1 route.
71
72 Compiling BIRD with --enable-debug no longer automatically activates debug
73 mode (-d option) nor local mode (-l option). Also, debug mode with output to
74 file (-D option) no longer not forces foreground mode (-f option).
75
76 The configure script now uses standard option --runstatedir, the old option
77 --with-runtimedir is deprecated.
78
79
