Check out this K2 update released today. K2 4.6.2 has some interesting enhancements to Oracle, CRM and SharePoint service objects.
K2 now supports calling client side object model in SharePoint. This means cloud/office365 connectivity without any coding. Nice.
You can also use CRM 2011 SmartObjects through the XRM SDK web services.
It also supports ref cursors much better with Oracle now. jEyLaBs influenced some of these Oracle connector enhancements :)
This update is for K2 blackpoint and K2 blackpearl. Check out the K2 4.6.2 Release Notes (KB001520).
