Summary of changes between Frotz 2.53 and Frotz 2.54: ===================================================== Frotz 2.54 was released on Wednesday April 13, 2022. This release's main attractions are official support for TOPS20 and cross-compilation to DOS. NEW FEATURES - Added changes to allow for compilation on a DEC PDP-10 mainframe running TOPS20. See INSTALL_PDP10. - Added a means to cross-compile to DOS by way of Open Watcom C version 2 and later. See INSTALL_DOS. - Added a quiet mode to dumb interface to quell startup messages. BUG FIXES - Fixed several problems with compilation under macOS. - Fixed wrong glyphs in DOS Frotz's Amiga font mode. 1/2 and 1/4 were there instead of the oe and OE ligatures. - Fixed a failure of the -q flag to actually silence sound effects. - Fixed an oversight in SDL Frotz that prevented some sounds from playing in Lurking Horror. - Made the dumb and curses interfaces read the resolution chunk from Blorb files. Previously they would assume a resolution of 320x200.
