From the ITC Press Release:

IntelliCAD 6.5 delivers polar tracking and spell checking features, supports the DIESEL programming language, works with many additional image file formats, implements enhanced performance in several key areas, and benefits from an upgraded user interface with all-new 24-bit color.


The ITC found a few blocking bugs after release of 6.5 and they are being fixed.

As I understand it this version should be available within a few weeks from now.

For the pricing side try CMS sales.
