+Version 2.0.4 (2019-02-27)
+ o OSPF: Opaque LSAs (RFC 5250)

+ o Preferred route counters are back
+ o Important BGP bugfix

+ o some minor bugfixes
+
+Version 2.0.3 (2019-01-05)
+ o MRT table dumps (RFC 6396)
+ o BGP Long-lived graceful restart
+ o BGP: Optional import table (Adj-RIB-In)
+ o BGP: Extend 'next hop keep' and 'next hop self' options
+ o BGP: Improved VRF support
+ o OSPF: Authentication trailer for OSPFv3 (RFC 7166)
+ o Babel: New option to randomize router ID
+ o Filter: Custom route attributes
+ o Filter: Support for src accessor to SADR source prefix
+ o Filter: Support for VPN_RD sets
+ o Filter: Make ifname attribute modifiable
+ o Perf: Protocol to measure BIRD performance internally
+ o More verbose error messages in config processing
+ o Log file size limit / log rotation
+ o Many bugfixes
+
+ 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.
+
+
+Version 2.0.2 (2018-03-22)
+ o Source-specific routing support for Linux kernel and Babel
+ o BGP: New option 'disable after cease'
+ o Filter: Allow silent filter execution
+ o Filter: Fixed stack overflow in BGP mask expressions.
+ o Several bugfixes
Notes:
- Definitions of OSPFv2, OSPFv3 and RIP NG protocols now use keywords
- 'ospf v2', 'ospf v3' and 'rip ng' instead of 'ospf2', 'ospf3' and 'ripng'.
+ Syntax prefix:netmask for IPv4 prefixes was dropped. Just use prefix/pxlen.
+
- Flows and ROAs no longer use phony next hops, so there is no need to use
- 'drop' or 'unreachable' in their static route definitions.
+Version 2.0.1 (2018-01-16)
+ o Linux MPLS kernel support
+ o Better handling of channels inherited from templates
+ o Default EBGP Route Propagation Behavior without Policies (RFC 8212)
+ o Many bugfixes
- See doc/bird.conf.example2 for configuration examples.
+ Notes:
+
+ To satisfy requirements of RFC 8212, external BGP protocols now require
+ explicit configuration of import and export policies.

Notes:
- Protocols and tables are now connected using explicit channels, most related
- protocol options (table, import, export, ...) are now channel options. See
- doc/bird.conf.example2 for configuration examples.
+ Tables are now defined with appropriate net type keyword. Protocols and tables
+ are now connected by explicit channels, most related protocol options (table,
+ import, export, ...) are now channel options. See doc/bird.conf.example2 for
+ configuration examples. Some options were removed/replaced.
