Definiens XD 2.0 General Availability

Dear Valued Customers,

On behalf of Definiens I am delighted to announce the availability of Definiens XD 2.0.

Definiens XD 2.0 is a major update for the Definiens XD product line. It includes, for the first time, both 32bit and native 64 bit editions of all products. Native 64 bit editions provide benefits for memory computationally intensive processes, such as 3D Rendering, Image Registration and the analysis of large multidimensional data sets. Aside from the memory handling characteristics, 32bit and 64bit editions are functionally equivalent. Definiens recommends customers using previous versions upgrade to Definiens XD 2.0. Please see the following knowledge base article for a more detailed discussion of the 64bit editions.
