You can now find the latest Windows binary of netpanzer development trunk here:
http://www.netpanzer.org/download/np/index.php?dir=Binaries/NetPanzer/Development/They are named snapshot-svn-[number].zip
Thre will be a new one every time important changes are added.
Linux users can as usual use svn repository and compile their own binary.
ninja(dev) gameserver is always there for testing.
Please send some feedback ;-)
note: these versions are not compatible with current netpanzer (they use a different transmission protocol).
