Christian,
We’re expecting to be able to release our fully-ported Kelper version around mid to end October.
Prior to that, we’ll be taking a look at minor tweaks to 2013 to SR2 to see if we can get it working on Kepler, this would be a milestone / beta release, however, if we are able to make it work.
Are there any particular features in Kepler that you are interested in? Would like to ensure that your needs are met when we get there.
