Next week we will be shipping the release of Extender that will upgrade from the Microsoft Dynamics GP 10.0 version of Extender to go along with the 2010 upgrade that is already available.
The next Extender release after that will be for the full Extender Enterprise release that will support upgrades from Dynamics GP 10.0 and 2010. This version is still undergoing some upgrade testing and you can participate by exporting your current solution and sending to us to help us in ensuring the upgrades will be completely successful. Please send to firstname.lastname@example.org.
The release of Extender Enterprise 2013 will be June 1st.
