Early Adopter 2 of Application Express 4.1 is coming. It will introduce a number of features which didn't make the cut for EA1, including Data Loading, Drag & Drop Calendars, and numerous translation improvements.
On or after this Friday, 10-JUN-2011, the current Application Express instance on http://tryapexnow.com will be terminated and a new one will be created. Nothing will be migrated. If there is any information you would like to save from your workspace, I encourage you to export it before Friday, 10-JUN-2011.
Thanks once again for the tremendous response and extremely valuable feedback and guidance. It is our customers who ultimately help make Application Express what it is.
