[B.A.T.M.A.N.] 0.3-beta vs. 0.3-exp

Hello everyone
first: nice work, i'm impressed!
i'm migrating 15 node olsr network to batman.
right now all nodes run olsrd and batman-0.2 parallel,
but there are some issues with "hidden nodes" (thanks to Axel for 
the bmx-reference-manual)
so my question, which of the switches from bmx (if any) are available 
in the 0.3-beta versions, or is the beta just something like 
0.3-exp --bmx-defaults ?

cheers

  --Jan

All switches available in 0.3-beta have been documented by Wesley on the 
corresponding man page:
http://downloads.open-mesh.net/batman/development/sources/batmand_0.3-beta-current_sources/man/batmand.8.html
and batmand_howto:
https://www.open-mesh.net/batman/doc/batmand_howto.pdf

The switches mentioned in the bmx manual are not available in 0.3-beta. That 
is one of the differences between the two branches. The objective of the 
0.3-beta branch is to always identify the best paramtrization automatically, 
relieving the administrator from the task of identifying appropriate 
parameters. 
For the "hidden nodes" issues, the 0.3-beta implementation should 
automatically hide the existence of all non-primary interface originators 
beyond the local neighbor horizon and instead send host network 
advertisements (HNAs).

No! The --bmx-defaults directive activates features from the 
batmand-experimental branch which might or might not find its way into the 
final batmand-0.3 release. 

The --bmx-defaults directive is supposed to always enable the 
latest "state-of-the-art" of the current batmand-exp implementation. 
Therefore the functionality enabled by this switch will change with future 
versions. Currently the --bmx-defaults switch implements the same parameters 
as the --graz-2007 switch. And this switch is supposed to remain as it is 
also in future versions.
