Hi Dario,
We'd love to work with you.
Here is what is happenning with the release.
Rocael is rolling it out at Galileo (postgres). He has a small install to do some testing and is then planning on migrating from ACS 3.4.
At Sloan, we currently have reached the point where we
a) put all our fixes into the .LRN that were appropriate to .LRN
b) merged the Sloan code base with the core .LRN and are testing that
c) have a hit list of bugs we are fixing
In mid-August, we'll be upgrading to a release candidate of .LRN 2.1.
Then we will continue with more bug fixing and customizations and do .LRN 2.1.1, ect. for a few months after that.
