Hi,
I worked today on a small project [1] to recreated all current features for 0.3 on top of the current changeset in maint. This would be handy when Andrew Lunn will send them to the kernel folks.
I discovered several small differences between maint and master which results in slightly different content in the rebase branch. This comes from the missing merged README and CHANGELOG and some inconsistent changes in my "80 chars per line" patch. I would like to encourage to merge that changes even if the README has currently some outdated information.
I would also want to ask Daniel Seither, Simon Wunderlich and Marek Lindner to check if I accidentally changed their patches in a way they don't want to support. I know that the commit messages aren't up to date, but would like to receive any kind of corrections for them.
Best regards, Sven

Some changes in "batman-adv: Reduce max characters on a line to 80" for trunk and maint branch were made slightly different and should be synchronized for easier tracking of changes between them.

thanks a lot for this effort. I'm sure you spend some time on this!
