with attributions, may be found at:

The most major changes:

- - zebra RIB race fixed which led to inconsistencies between RIB and
   kernel FIB
- - aspath loop checking in bgpd had been broken, fixed.

All 0.99 BGP users will want to upgrade promptly to this release, but 
see also the known regressions.

0.99 OSPF users may wish to upgrade too. The OSPF users affected by 
bug #269 may wish to update the bug with the requested information. 
Testing and confirmation of the fix for bug #134, included in this 
release, would be appreciated.

Summary of changes which may affect end-users (in no particular 
order, and with quite arbitrary classification into 'major', 'minor' 
and 'enhancement'):

lib:
  major:
   [lib] Fix infinite recursion for errors on vtys with terminal monitor enabled
   [lib] Do not call vty_close in vty_log_out to avoid possible free memory access
  minor:
   [lib] vty_log shouldn't crash if called when vty isn't initiliased
  enhancement:
   [lib] Add support for Sun libc printstack to zlog_backtrace_sigsafe
   [lib] Optimise thread_call by caching pointer to thread history in the thread
   [lib] Bug #134: threads should be more robust against backward time jumps

zebra:
  major:
   [zebra] Fix forgetfulness wrt configured address on FreeBSD
   [zebra] Bug #268, Fix race between add/delete of routes, sanitise rib queueing
   [interface configuration] Preserve flag indicating address was set by quagga.
   [interface configuration] Try to avoid losing address info after shutdown.
  minor:
   [zebra] Connected routes must always be added to main table
   [zebra] IRDP: Move stream_free to where its created, probably fixing a leak
  enhancement:
   [debug] Improve zebra kernel socket debug message to include IP addresses.
   [debug] Debug messages to terminal vty sessions should include timestamps

bgpd:
  major:
   [bgpd] Fix crash on shutdown of peer
   [bgpd] Potential bug#287 fix, peer_delete should NULL out freed buffers
   [bgpd] aspath_loop_check was broken, fix it and the aspath unit test code.
  minor:
   [bgpd] fix mtype in XFREE and NULL out freed pointer
  enhancement:
   [bgpd] expand vty help for neighbor ... update-source
  known regressions:
   - peer prefix counts can drift, potentially dramatically when bgp
     dampening is not enabled. This is cosmetic, unless maximum-prefix
     is configured for any peer.
   - the 'shutdown' command may not work, sessions to shutdown peers can
     come up. Fix will be integrated to CVS after this release.

ospfd:
  major:
   [ospfd] Avoid getting NSM stuck in ExStart by using local view of DR/BDR
   [ospfd] Bug #288: do not change router ID unless forced by manual configuration
   [ospfd] Clear adjacency state for NSM changes down to TwoWay/ExStart
   [ospfd] early-return in nsm_event missed LLDown event, fixes use after free
  minor:
   [ospfd] Fix ospf passive-interface subcommand to create interface if necessary
   [ospfd] When writing out config, show "debug ospf nsm status" properly
   [ospfd] redistribute default no longer works after complete reconfig, fix

   [ospfd] NSSA translate-enabled ABR should declare itself as ASBR
   [ospfd] lsdb_delete/discard_from_db should be more robust to bad args
   [ospfd] Fix "show ip ospf neighbor A.B.C.D" to show all matches
   [ospfd] Raise ExchangeDone earlier, avoid often needless round of DD packets
  enhancement:
   [ospfd] Implement new ospf router subcommand "log-adjacency-changes [detail]"
   [ospfd] Improve Hello NetworkMask mismatch warning to give more info
   [ospfd] cleanup NSM neighbour delete through a new Deleted NSM state
   [ospfd] record timestamp and event of last NSM state change for neighbour
   [ospfd] Additional NSM neighbour state change stats/information
   [ospfd] draft-ogier-ospf-dbex-opt DB-exchange optimisation
   [ospfd] Bug #134, ospfd should be more robust to backward time change
  known regressions:
   - bug #269: reports of ospfd crashing, apparently when loading large
     number of external LSAs. No one has yet confirmed whether the
     problem has been fixed or still persists.
