    according to the kernel priority (-A).

    is explicitly specified on the "redistribute" line.

  * Routes are now automatically flushed when an interface goes down or an
    IPv4 address changes, which avoids desynchronisation between Babel and
    the kernel.

  * Fixed a bug that broke link-quality estimation, and could cause
    severe instability when we had both good and marginal neighbours.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
43 44 45
  * We now send retractions after a redistributed route is retracted.
  * Fixed a bug that could cause reliable messages (retractions and
    router-id switches) to only be sent twice.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
46
  * We no longer obey a silent time at startup, instead sending a bunch of
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
47
    retractions.  The silent time is inconvenient, but seldom useful.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
48 49
  * Updates for routes to self are now sent together with other updates
    (they used to be sent more frequently).
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
50 51 52
  * Fixes the configuration parser to interpret hello-interval as a number
    of seconds, as specified in the documentation (it used to be interpreted
    as a number of milliseconds).
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
53
  * INCOMPATIBLE CHANGE: the update interval is now a per-interface value,
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
54 55
    may be configured manually in the configuraton file, and defaults to
    4 times the hello interval.  The -u flag is gone.

    remain until the routing table entry was flushed.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
61 62 63 64
  * Implemented per-interface configuration of parameters such as link
    cost, hello interval etc.  The command-line flags are now only used to
    set defaults.

  * Fixed a bug that could cause a crash if an interface was repeatedly
    brought down and then back up.
  * Implemented some protection against time stepping when POSIX clocks are
    not available.

77 78 79 80 81

  * Maintain buffered updates per-interface, which makes multi-interface
    nodes significantly less noisy.
  * Changed the strategy for dealing with unfeasible routes to be slightly
    more generous while still avoiding loops.

23 October 2008: babel 0.90

  * INCOMPATIBLE CHANGE: all new Babel version 2 protocol, which is both
    more robust and less chatty than version 1.
  * Tweaked the strategies for sending triggered updates and unfeasible
    requests to be more conservative.
  * Minor optimisations all over the place.
  * Removed the protocol specification -- the version 2 spec is maintained
    separately.

137
    convergence in presence of packet loss.
Juliusz Chroboczek's avatar

138
  * Optimised the sending of updates to make them smaller.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
139 140
  * Don't forward requests multiple times; this should reduce the
    noise due to requests with no increase in convergence time.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
141
  * Fixed a bug that could cause a crash when resending requests.
Juliusz Chroboczek's avatar

    for extended periods of time.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
149
  * Implemented protection against out-of-date requests being sent and
Juliusz Chroboczek's avatar

150
    forwarded when a node loses its sequence number.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
151 152
  * INCOMPATIBLE CHANGE: reduced the cost of wired networks down to 96
    from 128.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
153 154
  * Tweaked the frequency at which a router's seqno increases, to make
    it more likely that a feasible route will be available when needed.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
155
  * Implemented garbage collection of old sources.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed

    idle when running Babel with the -i flag.

    when output filtering was used.

Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
168 169
  * Implemented the ability to automatically export local addresses (see
    the ``local'' keyword in redistribute specifications).  This should
170 171
    avoid the need to explicitly specify -X on the command line
    (Julien Cristau and Juliusz Chroboczek).
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
172 173 174
  * INCOMPATIBLE CHANGE: local routes (local interface addresses) are
    now exported by default.  Specify ``redistribute local deny'' to
    avoid that.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
175 176
  * Babel will now automatically choose a router id if none is
    specified on the command line.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
177 178
  * Automatically adapt to interfaces appearing or disappearing at runtime,
    as is usually the case when running over tunnels or VPNs.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
179 180
  * Changed the link quality computation algorithm to not discard very
    lossy links.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
181 182 183
  * Multi-hop requests will now be forwarded to an unfeasible successor
    under some circumstances.
  * Send multi-hop requests more aggressively.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
184 185
  * Send requests for a new seqno upon receiving an unfeasible update
    if it's better than what we have.
186
  * No longer consider the age of routes in route selection.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
187
  * Added ability to run as a daemon.

196 197

  * Babel will now automatically check for interfaces' up/down status,
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
198
    IPv4 address, and optionally for carrier sense.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
199 200
  * Implemented the -w option, which disables all optimisations for
    wired interfaces.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
201
  * Implemented support for non-default routing tables.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
202 203

    Julien Cristau).

  * Fixed a bug that prevented requests from being parsed correctly.
  * Fixed a bug that prevented IHU intervals from being sent.
  * Respect reboot_time even after an id change.
  * Deal with neighbours rebooting and losing their hello seqno when
    computing link quality.

229 230 231 232 233
23 September 2007: babel 0.4

  * Fixed incorrect expiration of old sources.  This could prevent
    convergence in some cases.

29 August 2007: babel 0.2

  * Made jitter computation depend on how urgent a given message is.
    This dramatically improves convergence speed, without increasing
    network load.
  * Fixed a bug that prevented neighbour associations from being
    discarded at shutdown.

22 August 2007: babel 0.1

  * Initial public release.
