New version of Theseus released for Convenience Packages
2002/01/29, Theseus updated for CP 2.
A new version of Theseus has been released to support the Convenience Packages. Users of Convenience Package 2 must use this release. This new version is known as Theseus4. To get this new version, select Theseus4 to get the executable. Run the program in a new directory and see the README file for install instructions. This version, unlike prior Theseus3 versions, does not use a device driver, and you may need to make changes in your CONFIG.SYS if you have a prior version of Theseus3 installed. Details are in the README file.

This new version will work correctly only with Convenience Packages (1 and 2). Use Theseus3 for other OS/2 version.
