Allegro and OrCAD 17.0 design solution with new features, enhanced customization capabilities, and simulation performance improvements that provide customers a shorter, more predictable path to product creation. 17.0, as with all major dot zero releases, contains a number of architectural changes that will have an adoption overhead for customers, such as 64Bit only operating system, database changes that require a database update and a new library padstack structure. Through discussions with customers around the world we have learned that a 2015 mandatory update to 17.0 may require more preparation at some customer sites. Therefore the OrCAD and Allegro management team have decided to create and release a new feature packed 2015 version of 16.6 (16.6-2015) that will deliver new OrCAD and Allegro products as well as new functionality tiering of the OrCAD and Allegro base PCB products and pull forward some of the key 17.0 features such as Shape Edit application mode. This new 16.6-2015 release is being planned for June'2015. Therefore 17.0 is being re-positioned as a limited access Early Adopter Program (EAP) release, available and supported for production work for those companies using Allegro who want/need to move to a 64Bit operating system and/or begin to take advantage of the new database Padstack support. With the new feature-rich 16.6-2015 release we do not expect a large number of customers will want to upgrade to 17.0.
