0.82.6    Resizing the window in SDL 1.x Windows builds     fixed to work correctly in the latest build     (1803) of Windows 10. Prior to this fix, resizing     the window on that build would quickly hit a deadlock     that prevented the user from moving or resizing the     window again after that point.     PC-98 dosbox.conf option added to select between     accurate key/shift mapping, vs an alternate mapping     appropriate for US keyboards (Yksoft1)     SDL 1.x for Linux/X11 modified to differentiate     Ro and Yen keys despite X11 xkbmap apparently     mapping both to the backslash. The keymap is     queried to detect the scancodes at startup     in order to return the correct SDLK constant.     SDL 1.x and DOSBox-X mapper code updated to     correctly map Ro, Yen, @ ^ ; : keys on a JP     keyboard in Windows and Linux.     PC-98 keyboard BIOS handling updated to generate     ASCII codes according to PC-98 layout, instead     of by US keyboard layout.     Mapper updated to support @ (at sign) key,     ^ (caret) key, and a few other keys that     exist on JP keyboards.     "Hold" modifier for mapper bindings fixed.     It is now possible to tap the key again to     release the hold.     VHD differencing disk support added (Shane32)     INT 18h AH=0Ah updated to support 20-line     text mode. Some games use the 20-line text     mode to space the text out vertically.     Such games will display correctly now.     INT 18h now maintains text layer state     in BIOS data area byte 0x53C, just as     the actual BIOS does.     Added PC-98 INT 18h function AH=0Ah and     AH=0Bh to support BIOS calls that enable     "Simple Graphics" mode. This fixes     problems with other games having vertical     lines over the graphics, even though     these games do not appear to use the     simple graphics at all. (yksoft1)     Added support for PC-98 "Simple Graphics"     mode of text layer attribute bit 4. When     enabled, the attribute bit 4 changes     meaning from vertical line to a bit     indicating that the 8-bit character is     a low resolution 2x4 bitmap to be     displayed in the text layer. This fixes     score and status display in Carat.     PC-98 INT 18h now implements AH=31h to     report CRTC, text and graphics state and     24khz/31khz video mode selection. This     fix allows some games including Touhou     Project to pace it's gameplay correctly     in either video mode.     MinGW HX DOS builds default to host key     F12 again     PC-98 mode now offers selection between     24khz and 31khz video modes (yksoft1)     KEYB.COM fixed to load only the fonts the     ROM BIOS has allocated. This fixes a guest     system crash if using KEYB.COM with     machine=ega     Moved host key to F11 for Windows. F12 is     already taken by some internal debugging     voodoo within Windows itself.     DOSBox-X codebase now strongly encourages     compilation with C++11, will become     required soon.     BOOT command fixed to make it possible to     IMGMOUNT multiple floppies to drive 1, and     boot from another disk in drive 0. This     should enable the use of DOSBox-X with     PC-98 games that expect to boot from drive     A and the user to rotate through floppies     in drive B.     IMGMOUNT fixed to support mounting with no     filesystems and multiple disk images, and     using the "swap floppy" command to rotate     through them.     Added options to BOOT command that allows     specifying multiple disk images and an option     that says to swap disk images only through     one drive.     VHD dynamic support added (shane32)     INT 10 AH=9 background color fixed in 256-color     VGA modes.     Intro text updated to reflect new default     key bindings.     Mapper shortcuts not in common use now exist     without any default binding, and most existing     default bindings are now associated with the     "host" key.     Added 4th modifier "host" key to the mapper.     This "host" key is F12 by default. The intent     is to eventually move most mapper shortcuts     to some combination of F12 and another key,     rather than many shortcuts scattered over the     keyboard. Existing dosbox mapper files should     continue to work.     Renderer and 32bpp VGA display code fixed to     reorder RGBA order for correct display on Intel     Mac OS X systems. Mac OS X, on Intel systems,     uses a strange BGRA 32bpp format that requires     some adjustment on our part to display correctly.     Added more 24bpp INT 10h VESA BIOS modes.     Removed per-sector debug messages from VFD/FDD     image support code.
