365     [Lauri Pesonen]
366     - prefs.cpp: remodeled to allow platform-specific prefs items (list of
367     keywords is kept in table)
368     - video.cpp/cscSetEntries: luminance mapping uses integer instead of
369     floating point math
370     - video_*.cpp: on most systems, the frame buffer is allocated with
371     two additional lines as some ROM versions seem to write behind
372     the frame buffer proper
373     - BeOS/Unix/sysdeps.h: defined X86_ASSEMBLY on i386/GCC systems
374     - BeOS/Unix/sysdeps.h: redefined get/put_mem() functions to take and
375     return an uae_u32 value, added some more x86 optimizations
376     - Unix/serial_unix.cpp/kSERDBaudRate: rates between 57600 and 65535
377     result in a rate of 57600 [Lauri Pesonen]
378    
379     V0.4 (alpha) - 10.Apr.1999
380     - upgraded to UAE 0.8.8 CPU, CPU is now built with "gencpu", UAE sources
381     moved to "uae" directory
382     - new preferences item "rom" to specify the path of the ROM file
383     - new preferences item "ether" for Ethernet driver
384     - new INTFLAG_ETHER interrupt flag
385     - main_*.cpp: added ChoiceAlert()
386     - main_*.cpp: disabled UAE FPU (as it is buggy)
387     - serial_*.cpp: device_name is now a "const char *"
388     - serial_*.cpp: implemented monitor (#define MONITOR 1 to activate)
389     - *.h: changed "#ifdef _XXX_H_" to "#ifdef XXX_H" as symbols starting
390     with an underscore are reserved
391     - rom_patches.cpp: icon data moved to sony/disk/cdrom.cpp
392     - rom_patches.cpp: removed unnecessary a0/a1 save/restore from drivers
393     - slot_rom.cpp: removed unnecessary a0/a1 save/restore from drivers
394     - serial_defs.h: added error codes
395     - AmigaOS: the Kickstart ROM is no longer used to redirect NIL pointer
396     accesses as this crashes some machines (especially 68040-based);
397     a scratch memory block is used instead
398     - AmigaOS/serial_amiga.cpp: implemented
399     - AmigaOS/ether_amiga.cpp: implemented
400     - AmigaOS/sys_amiga.cpp: SysAddSerialPrefs() now returns real defaults
401     - AmigaOS/main_amiga.cpp: when the memory for the Mac RAM and ROM
402     cannot be allocated, an error message is displayed (instead of crashing)
403     - AmigaOS/main_amiga.cpp: interrupts are disabled during execution
404     of an EMUL_OP routine
405     - AmigaOS/asm_support.asm: the CTRL-C handler checks for pending
406     AmigaDOS operations
407     - AmigaOS/asm_support.asm: the interrupt signal exception is rethrown
408     when the interrupt level in EmulatedSR gets lowered while interrupts
409     are pending
410     - BeOS: switched from project files to Be supplied makefile system
411     - BeOS/ether_beos.cpp: implemented
412     - BeOS/serial_beos.cpp: modem status of parallel device is returned
413     as (dsrEvent | dcdEvent | ctsEvent)
414     - BeOS/serial_beos.cpp: implemented kSERDBaudRate
415     - BeOS/serial_beos.cpp: serdtDCE is set in PrimeIn()/PrimeOut()
416     - Unix/serial_unix.cpp: added support for parallel ports
417     - Unix/serial_unix.cpp: serdtDCE is set in PrimeIn()/PrimeOut()
418     - Unix/video_x.cpp: pressing F12 and q will quit Basilisk II in DGA mode
419     (useful when it crashed)
420    
421     V0.3 (alpha) - 14.Mar.1999
422     - Unix/video_x.cpp: added 15, 16 and 32 bit window modes [Bill Huey]
423     - BeOS/video_beos.cpp: "screen" prefs item is now either
424     "win/<width>/<height>" for window mode or "scr" for full-screen
425     mode
426     - added documentation of preferences file format to README
427    
428     V0.2 (alpha) - 11.Mar.1999
429     - tested with ROM versions 19 and 26
430     - prefs.cpp: renamed TYPE_BOOL to TYPE_BOOLEAN beacuse of name clash on
431     BeOS R4.1
432     - uae_memory.cpp: added support for frame buffer pixel type conversion
433     in virtual addressing mode, the Mac frame buffer layout now has to be
434     specified in MacFrameLayout (video.h)
435     - Unix/video_x.cpp: the "screen" prefs item is now read to select
436     window mode (with a specified window size) or DGA mode
437     - Unix/video_x.cpp: DGA mode supports 15, 16 and 32 bit modes (packed
438     24 bit pixels don't work)
439     - Unix/Makefile.linux: added -D_REENTRANT to compiler flags
440    
441     V0.2 (alpha) - 23.Jan.1999
442     - first alpha release
