  * 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.

  * We no longer obey a silent time at startup, instead sending a bunch of
Juliusz Chroboczek's avatar

7
    retractions.  The silent time is inconvenient, but seldom useful.

  * Updates for routes to self are now sent together with other updates
    (they used to be sent more frequently).

  * 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 committed
13 14
  * INCOMPATIBLE CHANGE: the update interval is now a per-interface value,
    and defaults to 5 times the hello interval.  The -u flag is gone.

  * Fixed a bug introduced in 0.17 that caused recently retracted routes to
    remain until the routing table entry was flushed.

  * 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.

  * 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.

  * Fixed a bug that would cause multi-hop requests to be spuriously resent.

  * Made a number of micro-optimisations throughout.

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.

    convergence in presence of packet loss.

97
  * Optimised the sending of updates to make them smaller.

  * Don't forward requests multiple times; this should reduce the
    noise due to requests with no increase in convergence time.

    forwarded when a node loses its sequence number.

    from 128.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
112 113
  * Tweaked the frequency at which a router's seqno increases, to make
    it more likely that a feasible route will be available when needed.

    idle when running Babel with the -i flag.

127 128
  * Implemented the ability to automatically export local addresses (see
    the ``local'' keyword in redistribute specifications).  This should
129 130
    avoid the need to explicitly specify -X on the command line
    (Julien Cristau and Juliusz Chroboczek).
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
131 132 133
  * 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
134 135
  * Babel will now automatically choose a router id if none is
    specified on the command line.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
136 137
  * 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
138 139
  * Changed the link quality computation algorithm to not discard very
    lossy links.
Juliusz Chroboczek's avatar

140 141 142
  * 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
143 144
  * Send requests for a new seqno upon receiving an unfeasible update
    if it's better than what we have.
145
  * No longer consider the age of routes in route selection.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed

  * Babel will now automatically check for interfaces' up/down status,
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
157
    IPv4 address, and optionally for carrier sense.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed
158 159
  * Implemented the -w option, which disables all optimisations for
    wired interfaces.
Juliusz Chroboczek's avatar

  * Implemented support for non-default routing tables.
Juliusz Chroboczek's avatar
Juliusz Chroboczek committed

    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.

188 189 190 191 192
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.
