-Version 1.3.12 (2013-11-23)
+Version 1.4.0 (2013-11-25)
   o BFD protocol (RFC 5880).
   o BFD support for OSPF and BGP.
   o New 'allow local as' option for BGP.
   o Filters allows setting gw, ifname and ifindex.
   o Filter operator 'delete/filter' extended to bgp_paths.
   o Filter operator 'len' extended to [e]clists.
-  o PID file support.
+  o BIRD client now allows shorthands for noninteractive commands.
+  o Flag -P for PID file support.
+  o Flag -f added to force BIRD to run in foreground.
+  o Protocol export/import/receive limits are checked during reconfiguration.
   o Several bugfixes and minor improvements.
+  o Several minor but incompatible changes:
+     - IBGP is multihop by default.
+     - Changes primary address selection on BSD to the first one.
+     - Integers in filters are handled as unsigned.
+     - ISO 8601 time formats used by default.
+     - Import of device routes from kernel protocol allowed.
+     - Last state change now tracks just protocol state change.
+     - Minor changes to default router ID calculation.
  
 Version 1.3.11 (2013-07-27)
   o OSPF stub router option (RFC 3137).
