• IMGMOUNT now supports mounting a RAM drive (using -t ram) (Shane32)
• Direct3D fullscreen aspect ratio fixes, especially for
  monitors with a 5:4 aspect ratio (such as 1280x1024) (Shane32)
• "Show menu" in Windows builds system menu is now a toggle
  to show/hide the menu bar (Shane32)
• Fixed broken color palette with CGA composite and EGA
  machine emulation. Composite CGA and machine=ega displays
  properly again.
• According to documentation, IBM PC and PC-98 use different
  initial PC speaker frequencies. Update the code to match.
• 8254 I/O port alias at 3FD9h-3FDFh added, which is needed
  for several PC-98 games that program the PC speaker
  frequency through those ports instead of through 71h-77h
• New Intel 8255 emulation. PC-98 system 8255 emulation
  now uses this emulation, along with PC speaker emulation.
• Fixed XMS memory copy functions to enable the A20
  gate so extended memory copies work correctly whether
  or not the DOS application in question made the call
  with A20 enabled. This fixes crashes and memory
  corruption while installing Windows 3.1 using SETUP.EXE.
• "CLS" now sends the proper ANSI escapes to clear the
  console in PC-98 mode.
• BIOS logo in PC-98 fixed to clear graphics RAM and
  set graphics back to 8-color digital mode when booting
  to DOS. This should fix palette errors and color issues
  with older PC-98/PC-88 games that use the 8-color
  graphics modes.
• Added PC-98 INT 1Ch timer interval BIOS function,
  and timer countdown routine in IRQ 0.
• Windows builds now incorporate pdcurses and enable
  the debugger interface (bulletshot60)
• DOSBox-X now tracks the systemwide keyboard layout
  on Windows, and acts on user changes to the keyboard
  and language in the system.
• Removed hack code in SDL 1.x that sets DOSBox-X's
  keyboard layout to the US layout even if the host
  uses anything else.
• Fix CPU cycles count increment not to nag you to use
  core=dynamic if a) dynamic core is not available or
  b) you're already using dynamic core.
• Added dynamic core back, it seems to be very stable
  again.
