          audio device capabilities (actual sample rate is also determined)
          [Alexander R. Pruss]
        - Unix/audio_oss_esd.cpp: "silence" in 8-bit mode used wrong fill
          value (0 instead of 0x80) [Alexander R. Pruss]

        - BeOS/Unix/sysdeps.h: defined X86_ASSEMBLY on i386/GCC systems
        - BeOS/Unix/sysdeps.h: redefined get/put_mem() functions to take and
          return an uae_u32 value, added some more x86 optimizations
        - Unix/serial_unix.cpp/kSERDBaudRate: rates between 57600 and 65535
          result in a rate of 57600 [Lauri Pesonen]

V0.4 (alpha) - 10.Apr.1999
        - upgraded to UAE 0.8.8 CPU, CPU is now built with "gencpu", UAE sources
          moved to "uae" directory
        - new preferences item "rom" to specify the path of the ROM file
        - new preferences item "ether" for Ethernet driver
        - new INTFLAG_ETHER interrupt flag
        - main_*.cpp: added ChoiceAlert()
        - main_*.cpp: disabled UAE FPU (as it is buggy)
        - serial_*.cpp: device_name is now a "const char *"
        - serial_*.cpp: implemented monitor (#define MONITOR 1 to activate)
        - *.h: changed "#ifdef _XXX_H_" to "#ifdef XXX_H" as symbols starting
          with an underscore are reserved
        - rom_patches.cpp: icon data moved to sony/disk/cdrom.cpp
        - rom_patches.cpp: removed unnecessary a0/a1 save/restore from drivers
        - slot_rom.cpp: removed unnecessary a0/a1 save/restore from drivers
        - serial_defs.h: added error codes
        - AmigaOS: the Kickstart ROM is no longer used to redirect NIL pointer
          accesses as this crashes some machines (especially 68040-based);
          a scratch memory block is used instead
        - AmigaOS/serial_amiga.cpp: implemented
        - AmigaOS/ether_amiga.cpp: implemented
        - AmigaOS/sys_amiga.cpp: SysAddSerialPrefs() now returns real defaults
        - AmigaOS/main_amiga.cpp: when the memory for the Mac RAM and ROM
          cannot be allocated, an error message is displayed (instead of crashing)
        - AmigaOS/main_amiga.cpp: interrupts are disabled during execution
          of an EMUL_OP routine
        - AmigaOS/asm_support.asm: the CTRL-C handler checks for pending
          AmigaDOS operations
        - AmigaOS/asm_support.asm: the interrupt signal exception is rethrown
          when the interrupt level in EmulatedSR gets lowered while interrupts
          are pending
        - BeOS: switched from project files to Be supplied makefile system
        - BeOS/ether_beos.cpp: implemented
        - BeOS/serial_beos.cpp: modem status of parallel device is returned
          as (dsrEvent | dcdEvent | ctsEvent)
        - BeOS/serial_beos.cpp: implemented kSERDBaudRate
        - BeOS/serial_beos.cpp: serdtDCE is set in PrimeIn()/PrimeOut()
        - Unix/serial_unix.cpp: added support for parallel ports
        - Unix/serial_unix.cpp: serdtDCE is set in PrimeIn()/PrimeOut()
        - Unix/video_x.cpp: pressing F12 and q will quit Basilisk II in DGA mode
          (useful when it crashed)

V0.3 (alpha) - 14.Mar.1999
        - Unix/video_x.cpp: added 15, 16 and 32 bit window modes [Bill Huey]
        - BeOS/video_beos.cpp: "screen" prefs item is now either
          "win/<width>/<height>" for window mode or "scr" for full-screen
          mode
        - added documentation of preferences file format to README

V0.2 (alpha) - 11.Mar.1999
        - tested with ROM versions 19 and 26
        - prefs.cpp: renamed TYPE_BOOL to TYPE_BOOLEAN beacuse of name clash on
          BeOS R4.1
        - uae_memory.cpp: added support for frame buffer pixel type conversion
          in virtual addressing mode, the Mac frame buffer layout now has to be
          specified in MacFrameLayout (video.h)
        - Unix/video_x.cpp: the "screen" prefs item is now read to select
          window mode (with a specified window size) or DGA mode
        - Unix/video_x.cpp: DGA mode supports 15, 16 and 32 bit modes (packed
          24 bit pixels don't work)
        - Unix/Makefile.linux: added -D_REENTRANT to compiler flags
