New RIB code provides multiple nexthop for a prefix.
Equal cost multipath works on GNU/Linux.
Communication between protocol daemon and zebra is changed to UNIX domain socket.
BGP trap MIB works.
BGP route selection is improved and various option is provided.
New OSPF packet read method.
PLEASE UPDATE WHOLE SUITE including zebra, bgpd, ripd, ripngd,
ospfd, ospf6d when you update from previous version. Zebra protocol
is changed so there may be some protocol mismatch when you don't
update everything.
+ OSPF works on x86 Solaris box.
+ OSPF neighbor is supported.
+ IPv6 inteface's address information propagation bug is fixed.
+ BGP's various MED comparison methods are added.
+ BGP read lock problem is fixed.
+ Zebra works on OpenBSD again.
s/CFLAGS/CPPFLAGS/, to make vtysh build successful.

--- from announcement on zebra@zebra.org
o Zebra protocol is changed to support multipath and distance configuration.
o Distance configuration is enabled.
o Metric value is passed from protocol daemon to zebra.
o "default-information originate" for OSPF.
o Soft reconfiguration for BGP.
o Route refresh support for BGP.
o MD5 authentication for RIP.
o Introducing integrated shell vtysh.
PLEASE UPDATE WHOLE SUITE including zebra, bgpd, ripd, ripngd, ospfd,
ospf6d when you update from previous version. Zebra protocol is
changed so there may be some protocol mismatch when you don't update
everything.
key changes from www.zebra.org:
Many ospfd related bugs are fixed.
Now OSPF module becomes very stable again ;-).
MPLS-VPN PE-RR functionality is added to bgpd.
RIP,zebra interface up/down handling improved.
0.85 -> 0.86 changes:
* Changes in lib
** Fix bug of exec-timeout command which may cause crush.
** Multiple same policy for "access-list", "ip prefix-list, "as-path
access-list", "ip community-list" is not duplicated.
** It used to be "ip prefix-list A.B.C.D/M" match routes which mask >=
M. Now default behavior is exact match so it only match routes which
mask == M.
* Changes in bgpd
** "match ip address prefix-list" is added to route-map.
** A route without local preference is evaluated as 100 local preference.
** Select smaller router-id route when other values are same.
** Compare MED only both routes comes from same neighboring AS.
** "bgp always-compare-med" command is added.
** Now MED value is passed to IBGP peer.
** When neighbor's filter is configured with non-existent access-list,
as-path access-list, ip prefix-list, route-map. The behavior is
changed from all permit to all deny.
* Changes in ospfd
** Fix bug of external route tag byte order.
** OSPF Neighbor deletion bug which cause crush is fixed.
** Some route calculation bug are fixed.
** Add sanity check with router routing table.
** Fix bug of memory leak about linklist.
** Fix bug of 1-WayReceived in NSM.
** Take care of BIGENDIAN architecture.
** Fix bug of NSM state flapping between ExStart and Exchange.
** Fix bug of Network-LSA originated in stub network.
** Fix bug of MS flag unset.
** Add to schedule router_lsa origination when the interface cost
changes.
** Increment LS age by configured interface transmit_delay.
** distribute-list is reimplemented.
** Fix bug of refresh never occurs.
** Fix bug of summary-LSAs reorigination. Correctly copy
OSPF_LSA_APPROVED flag to new LSA. when summary-LSA is reoriginatd.
** Fix bug of re-origination when a neighbor disappears.
** Fix bug of segmentation fault with DD retransmission.
** Fix network-LSA re-origination problem.
** Fix problem of remaining withdrawn routes on zebra.
* Changes in ripd
** Do not leave from multicast group when interface goes down bug is
fixed.
* Changes in zebra
** Remove client structure when client dies.
** Take care static route when interface goes up/down.
(changelog from www.zebra.org)
Fix bug of OSPF LSA memory leak.
Fix bug of OSPF external route memory leak.
OSPF AS-external-LSA origination bug was fixed.
And other many ospfd problems are fixed.
BGP Route reflector's originator-id bug is fixed.
RIPv1 update is done by class-full manner.

GNU Zebra is not yet released, so this NEWS is about beta version.
* Changes in zebra-0.84b
* Changes in lib
** Fix bug of inet_pton return value handling
* Changes in bgpd
** Fix bug of BGP-4+ link-local address nexthop check for IBGP peer.
** Don't allocate whole buffer for displaying "show ip bgp". Now it
consume only one screen size memory.
* Changes in ripd
** Fix debug output string.
** Add RIP peer handling. RIP peer are shown by "show ip protocols".

New beta zebra-0.79 is out:
ftp://ftp.zebra.org/pub/zebra/zebra-0.79.tar.gz
This beta release's main topic is ospfd. Now it works pretty well!
We know it surely has bugs inside, so when you find it please let us
know. ABR,ASBR,Virtual Linux functionality is added. Flooding codes
and LSA database codes are almost rewritten. Terminal interface of
ospfd will show detailed information about LSAs.
There was a report about RIPv2's netmask is zero case. I've changed
ripd codes when netmask is not valid. ripd will ignore the entry.
0.77 -> 0.78:
>ospfd does LSA flodding correctly. Some bug about DD processing, LSA
>ack are fixed. LSA structure is changed for LSA aging support.
>Interface index setting bug with Linux without netlink interface is
>fixed. Some ripd's bugs which introduced in zebra-0.77 are fixed.
>Zebra message is changed to support dynamic interface change
>notification.
http://mail.vbs.at/archive/zebra/zebra/msg00612.html
0.78 -> 0.78a:
>I introduced serious bug about the route does not deleted from zebra's
>routing table. This problem only occur with IPv4 route. I've fixed
>the problem. Would you mind to test below tar-ball?

New beta zebra-0.77 is out:
ftp://ftp.zebra.org/pub/zebra/zebra-0.77.tar.gz
This beta includes brand new ripd. Almost codes of ripd is rewritten.
ripd's dynamic `network' command configuration is improved. `timers
basic' command's semantics is changed to conforms to RFC2453. ripngd
is also updated as same as ripd. IPv6 kernel route handling bug is
fixed. SIGUSR1 reopen logging file. ospfd's bug of originating
network LSA is fixed. Redistribute routes handling is much improved.
Now `no redistribute' works as expected. BGP-4+ withdraw bug is
fixed. IPv6 router advertisement codes are added but not yet usable.
>This is the first beta relase which includes (partly) workable ospfd.
>Now ospfd works as inter area OSPF router. When it works properly
>route goes into the kernel. Please note it does not support intra
>area route, AS external route, multiple area, aging of LSA, etc...
>Please use ospfd only in test environment.
>
>BGP serious bug is fixed. ripngd is almost rewritten to conform to
>RFC2080. ospf6d's LSA data structure is improved. And also many bugs
>are fixed.
