Version 2.50 This release includes Unix Frotz, Dumb Frotz, SDL Frotz, and DOS Frotz. All have been tested and appear to be working correctly. With DOS Frotz in particular, had longstanding problems with integer overflows. These are fixed now. Unix Frotz's audio subsystem was revised by Mark McCurry. SDL Frotz finally corrects for adaptive palette images. Major changes coming up: * Add compile-time option for paging Zcode from disk instead of reading the whole thing into memory. This will allow for better perfomance on low-memory machines. * Port Frotz to the PDP-10 mainframe and maybe PDP-11. Contingent on disk-paging. * Create a new GTK3 user interface to resemble the interface of Windows Frotz. * Add language internationalization. Minor changes coming up: * Better control over row and column count for the SDL interface. * Preserve aspect ration when resizing SDL window.
