This is the EDB revision history.

v. 0.15
      - Added EDB integrity check
      - Fixed bug in I/O breakpoints with ins/outs instructions
      - Fixed bug in 'bp' command with action expression incorrectly
	recognised when offset range was used.
      - Altered behaviour of 'bi' command with overlapping break points.
	Bi will now preserve read breakpoint when write one is removed
	and vv. Action expression will be preserved when no new action was
	specified.
      - Variable-size trace buffer introduced. V changed to show only
	screenful of trace records
      - Added breakpoint on prefetch queue different from memory (BQ)
      - 80286 instructions added to disassembler
      - Chaged disassemble logic, so that instructions unavailable
	with current CPU type will be shown as 'invalid'
      - GF will now refuse to proceed while single-stepping.
      - G  will now accept stopping address as argument.
      - EDB will now break out on attempt to implicitly run full speed
	while single-stepping.
      - Fixed bug in 'pop sp' (removed increment by 2)
      - Added AAD/AAM support for bases other then 10
      - Added cf2al (0xD6) instruction
      - Added 80186 extended instruction set.
      - Added new section 'CPU Options' to configuration file.
	Possible values are: Processor and Prefetch.
      - Fixed push sp for 286 mode
      - Fixed bug in 8086 code for idiv instruction, so that quotient value
	of 0x8000 now causes exception 0 while in 8086 mode.
      - Fixed bug with return address of divide but zero exception in 286 mode.
      - ESC/WAIT are now sensitive to msw bits while in 286 mode.
      - call_interrupt now takes notice of idt.base in 286 mode.
      - illegal instructions call exception 6 in 80286 mode
      - Added prefetch queue support
      - Added support for MirrorPort option

v. 0.14 - First public release.
