We successfully upgraded MIT Sloan to .LRN 2.x this weekend. The technical team will post details soon and our thanks to everyone involved in the effort.
Our philosophy going forward will be to include in the official .LRN releases packages and code which have been thoroughly tested and in production use at some .LRN site. This is to ensure a highly level of quality assurance in every release.
good to know that you are now using 2.x, actually, we would really appreciate you information about how was the process and if you kindly are able put it back your last minute patches, since Galileo is upgrading this weekend ;)
