Dear all,

You will find Babel 0.11 on


A lot of small tweaks in this version, but little significant changes.
Most notables is a fix for a crash that would happen if an interface
with large MTU was added at runtime, and some preliminary moderation
of requests.

With this version, Babel is mostly feature-complete as far as I am
concerned.  Still missing is resending of incremental route updates,
and more work is needed on the parameters of triggered updates.


29 March 2008: babel 0.11

  * Implemented sub-second hello and update intervals.
  * Fixed a bug that could prevent the best route from being selected
    for extended periods of time.
  * Implemented protection against out-of-date requests being sent and
    forwarded when a node loses its sequence number.
  * INCOMPATIBLE CHANGE: reduced the cost of wired networks down to 96
    from 128.
  * Tweaked the frequency at which a router's seqno increases, to make
    it more likely that a feasible route will be available when needed.
  * Implemented garbage collection of old sources.
  * Implemented coalescing of unicast messages.
  * Fixed a bug that could cause a crash when a link's MTU changes.
  * Fixed a bug that could delay noticing that a network is no longer
    idle when running Babel with the -i flag.
  * Fixed a bug that could cause incorrect metrics to be advertised
    when output filtering was used.
  * Fixed a bug that could cause incorrect link costs to be computed when
    a neighbour reduces its hello interval.
  * Fixed some minor issues with the ordering of outgoing messages.
