Aldus FreeHand 4

Aldus FreeHand 4 is the fourth major release of FreeHand developed by Altsys Corporation and the first to support PowerPC processors. It is also the last major version to be marketed by Aldus. It is feature-equivalent with Virtuoso 2.0 for NeXTSTEP.

Features
FreeHand 4.0 included support for reading and writing Adobe Illustrator 88 and Illustrator 3.0 files, which was an optional feature in the previous version.

Lawsuit
After Aldus Corporation was acquired by Adobe Systems in August 1994, Altsys, which had retained development rights, sued to regain marketing rights to FreeHand, citing a non-compete clause because of Adobe's development of Adobe Illustrator. Altsys also filed for the trademark to Altsys FreeHand in July 1994 in event they needed to self-publish the product. Altsys was then acquired by Macromedia in January 1995.
