* Changes in zebra

** Basic IPv6 router advertisement codes added.  It is not yet usable.

** Fix IPv6 route addition/deletion bug is fixed.

** `show ip route A.B.C.D' works

* Changes in bgpd

** When invalid unfeasible routes length comes, bgpd send notify then
continue to process the packet.  Now bgpd stop parsing invalid packet
then return to main loop.

** BGP-4+ withdrawn routes parse bug is fixed.

** When BGP-4+ information passed to non shared network's peer, trim
link-local next-hop information.

** `no redistribute ROUTE_TYPE' withdraw installed routes from BGP
routing information.

** `show ipv6 route IPV6ADDR' command added.

** BGP start timer has jitter.

** Holdtimer configuration bug is fixed.  Now configuration does not
show unconfigured hold time value.

* Changes in ripngd

** Now update timer (default 30 seconds) has +/- 50% jitter value.

** Add timers basic command.

** `network' configuration is dynamically reflected.

** `timers basic <update> <timeout> <garbage>' added.

* Changes in ripd

** Reconstruct almost codes.

** `network' configuration is dynamically reflected.

** RIP timers now conforms to RFC2453.  So user can configure update,
timeout, garbage timer.

** `timers basic <update> <timeout> <garbage>' works.

* Changes in ospfd

** Bug of originating network LSA is fixed.

** `no router ospf' core dump bug is fixed.

* Changes in ospf6d

** Redistribute route works.

* Changes in zebra-0.76

* Changes in lib

** configure.in Linux IPv6 detection problem is fixed.

** Include SERVICES file to the distribution

** Update zebra.texi to zebra-0.76.

* Changes in zebra-0.75

* Changes in lib

** `termnal length 0' bug is fixed.

* Changes in zebra

** When zebra starts up, sweep all zebra installed routes.  If -k or
--keep_kernel option is specified to zebra dameon.  This function is
not performed.

* Changes in ripngd

** Aggreagte address command supported.  In router ripngd,
`aggregate-address IPV6PREFIX' works.

** Input route-map's bug which cause segmentation violation is fixed.

** route-map method improved.

** BGP-4+ nexthop detection improved.

** BGP-4+ route re-selection bug is fixed.

** After connection Established `show ip bgp neighbor' display BGP TCP
connection's source and destination address.

** In case of BGP-4+ `show ip bgp neighbor' display BGP-4+ global and
local nexthop which used for originated route.  This address will be
used when `next-hop-self'.

* Changes in ospfd

** Fix bug of DR election.

** Set IP precedence field with IPTOS_PREC_INTERNET_CONTROL.

** Schedule NeighborChange event if NSM status change.

** Never include a neighbor in Hello packet, when the neighbor goes
down.

* Changes in zebra-0.74

* Changes in lib

** Now `terminal length 0' means no line output control.

** `line LINES' command deleted.  Instead of this please use `terminal
length <0-512>'.

** `terminal length <0-512>' is each vty specific configuration so it
can not be configured in the configuration file.  If you want to
configure system wide line control, please use `service
terminal-length <0-512>'.  This configuration affects to the all vty
interface.

* Changes in zebra

** Installation of IPv6 route bug is fixed.

* Changes in bgpd

** Very serious bug of bgp_stop () is fixed. When multiple route to
the same destination exist, bgpd try to announce the information to
stopped peer.  Then add orphan write thread is added.  This cause
many strange behavior of bgpd.

** Router-id parsing bug is fixed.

** With BGP-4+ nexthop installation was done with global address but
it should be link-local address.  This bug is fixed now.

** When incoming route-map prepend AS, old AS path remained.  Now bgpd
free old AS path.

** `neighbor PEER weight <0-65535>' command added.

* Changes in ripngd

** Almost codes are rewritten to conform to RFC2080.

* Changes in ospfd

** SPF calculation timer is added.  Currently it is set to 30 seconds.

** SPF calculation works now.

** OSPF routing table codes are added.

** OSPF's internal routes installed into the kernel routing table.

** Now `ospfd' works as non-area, non-external route support OSPF
router.

** Call of log_rotate() is removed.

* Changes in ospf6d

** LSA data structure is changed.

** Call of log_rotate() is removed.

* Changes in zebra-0.73

* Changes in lib

** `config terminal' is changed to `configure terminal'.

** `terminal length <0-512>' command is added.

** Variable length argument was specified by `...'.  Now all strings
started with character `.' is variable length argument.

* Changes in zebra

** Internal route (such as iBGP, internal OSPF route) handling works
correctly.

** In interface node, `ipv6 address' and `no ipv6 address' works.

** Interface's address remain after `no ip address' bug is fixed.

** Host route such as IPv4 with /32 mask and IPv6 with /128 mask
didn't set RTF_GATEWAY even it has gateway.  This bug if fixed now.

* Changes in bgpd

** `match as-path' argument is used to be specify AS PATH value itself
directly (e.g. ^$).  But it is changed to specify `ip as-apth
access-list' name.

** iBGP route handle works without getting error from the kernel.

** `set aggregator as AS A.B.C.D' command is added to route-map.

** `set atomic-aggregate' command is added to bgpd's routemap.

** Announcement of atomic aggregate attribute and aggregator attribute
works.

** `update-source' bug is fixed.

** When a route learned from eBGP is announced to iBGP, local
preference was set to zero.  But now it set to
DEFAULT_LOCAL_PREF(100).

* Changes in ripd

IPv4 address.

* Changes in bgpd

** Change route-map's next-hop related settings.

set ip nexthop          -> set ip next-hop
set ipv6 nexthop global -> set ipv6 next-hop global
set ipv6 nexthop local  -> set ipv6 next-hop local

** Add `next-hop-self' command.

** Bind `quit' command to major nodes.

* Changes in zebra

** Point-to-point link address handling bug is fixed.

** Critical routing information base calculation bug check is fixed.

** zebra ipv4 message is extended to support external/internal route
flavor.

** Now if internal route doesn't has direct connected nexthop, then
nexthop is calculated by looking up IGP routing table.

* Changes in bgpd

`neighbor PEER interface IFNAME'.

* Changes in ospfd

** DD null pointer bug is fixed.

* Changes in zebra-0.69

* Changes in zebra

** zebra redistirbution supports dynamic notification of the route
change.  If you add static route while running zebra, it will be
reflected to other protocol daemon which set `redistribute static'.

** If static route installation is failed due to the error.  The
static route is not added to the configuration and zebra routing
table.

** zebra sets forwarding flag to on when it starts up.

** `no ip forwarding' turn off IPv4 forwarding.

** `no ipv6 forwarding' turn off IPv6 forwarding.

** Change `show ipforward' command to `show ip forwarding'.

** Input buffer overflow bug is fixed.

* Changes in bgpd

** `ip community-list' is added.
