Hi again,
new NDT version is coming soon, however there are last changes to be 
performed
before this. I have merged all changes to release into trunk, tested and 
fixed individual
small bugs. Next step will be to update our wiki pages to match new 
version which I will
be working on in nearest time.
However I wanted to ask two last questions to you:
1. So far new release package has been published in "downloads" section 
of google code
project but recently Google has disabled this option. Therefore should 
we place such archive
in some external source like Google drive where users could directly 
download this (and update
wiki with such link)? Or maybe just publish link to release tagged 
revision?

2. Also what about updating NDT links/software on another sites? I know 
that it will be performed
on M-lab but what about Internet2 website?

Regards
Sebastian
