0.83.7

• Implemented the x86 dynamic core for both 32-bit
  and 64-bit systems by re-porting the code from SVN.
  Dynamic core now supports either the dynamic_x86
  or the dynamic_rec core. The dynamic_x86 core will
  be used by default for x86 and x86_64 platforms and
  if "core=dynamic" is set, and Windows 9x can be run
  in this dynamic core (although at this time may
  encounter some issue with the S3 driver). You can
  also explicit specify setting "core=dynamic_x86" or
  "core=dynamic_rec" for either the dynamic_x86 core
  or the dynamic_rec core. Also thank joncampbell123
  for the 64-bit fix. (Wengier)
• You can now use your own save file (in addition to
  save slots! There are now a "Use save file" toggle
  item and "Browse save file..." for browsing save
  files on your computer. A config option "savefile"
  (in [dosbox] section) is added to specify a save
  file to use at start. (Wengier)
• Save state feature now allows users to optionally
  enter remarks when saving a state. A submenu group
  "Save/load option" is added (under "Capture") where
  you can toggle menu items "No remark when saving
  state" (for disabling input of remarks when saving)
  and "force load state mode". A menu item "Display
  state information" is added as well to display the
  information of the saved state. (Wengier)
• DOSBox-X will now use native dialog box to display
  quit warnings and save state errors. (Wengier)
• Changed some DOS error messages (such as "Illegal
  command" which now reads "Bad command or filename")
  similar to real DOS systems. (Wengier)
• ADDKEY and INT2FDBG commands now appear as programs
  on Z: drive instead of shell commands. (Wengier)
• Improved the -z (move virtual drive Z:) function of
  MOUNT command. You can move the virtual drive as
  many times as you want, and save/load states will
  work even after you move the Z: drive. (Wengier)
• Enhanced the config option "freesizecap" to allow
  the setting "fixed" which is the same as "false",
  and a new setting "relative" is added, which will
  be similar to the setting "fixed" but the reported
  free disk size will also change relative to the
  change of the free disk size ever since. (Wengier)
• Added support for Opus CD-DA tracks by porting and
  cleaning up the source code from other projects.
  Many thanks to Marty Shepard and kcgen. (Wengier)
• Support for FluidSynth MIDI Synthesizer is now
  included in the MinGW builds by default just like
  Visual Studio builds. Set "mididevice=fluidsynth"
  and a soundfont file to use it. (Wengier)
• Enabled xBRZ scaler for Visual Studio SDL2 builds
  just like Visual Studio SDL1 builds. (Wengier)
• Added menu item "Show Sound Blaster configuration"
  under "Sound" menu to show the current information
  about Sound Blaster, and also menu item "Show MIDI
  device configuration" (also under "Sound" menu)
  to show information about the current MIDI device
  such as the soundfont file in use. (Wengier)
• Added "Mount multiple disk/CD images" option to the
  mounting options of the Drive menu to allow users
  to mount more than one disk/CD images to a drive,
  swappable from the menu. Also added separators to
  the Drive submenu to make it look better. (Wengier)
• Added new CPU types to the "Emulate CPU speed" menu
  group namely 286-25MHz, 386DX-25MHz, 486DX4-100MHz,
  486DX5-133MHz, Pentium-60MHz, Pentium-75MHz, and
  Pentium-90MHz. Thanks again for the data provided
  by the user maximus105. (Wengier)
• You can now select a special key (e.g. Alt+Tab,
  Ctrl+Break, Ctrl+Alt+Del, etc) to be sent from the
  key defined in the mapper editor. The key can be
  selected (Ctrl+Alt+Del by default) from the "Send
  special key" menu group in "Main" menu. (Wengier)
• Added full Ctrl+Break emulation at the BIOS and
  DOS level, updated console emulation to match.
  The "Pause" mapper shortcut is now moved to
  HOST[F11/F12]+Pause instead of Ctrl+Pause so that
  Ctrl+Break can work properly for users, and the
  function to send the Ctrl+Break key from the menu
  ("Send special key" under "Main") is added. Also,
  the PC-98 STOP key now functions the same as the
  Ctrl+C and Ctrl+Break keys in IBM PC mode.
• Added functions "CopyToClipboard" and "QuickRun" to
  the mapper editor so that you can use shortcuts to
  activate them (default shortcuts: HOST(F11/F12)+A
  and HOST(F11/F12)+Q respectively), and a default
  shortcut HOST(F11/F12)+V is added to the clipboard
  paste function. Meanwhile, FullCore and SimpleCore
  shortcuts are removed from the mapper. (Wengier)
• Added two new menu items in the "Shared clipboard
  functions" menu group under "Main", including "Copy
  all text on the DOS screen" which will copy all
  screen text to the clipboard, and "Stop clipboard
  pasting" which allows user to stop pasting in the
  middle of pasting long clipboard content. (Wengier)
• The mouse copy/paste feature is now available for
  non-Windows systems on SDL2 builds. Also, pasting
  from the clipboard with a mapped shortcut is also
  available for Linux/X11 on SDL1 builds. (Wengier)
• Added "Use US keyboard layout" toggle menu item in
  the "PC-98" menu group under "Video" to select
  whether to force the default US keyboard layout in
  PC-98 mode, same as the "pc-98 force ibm keyboard
  layout" config option in [pc98] section. Also moved
  the "PC-98 PIT master clock" options from the "DOS"
  menu to this menu group. (Wengier)
• The full dosbox-x.reference.conf file is renamed to
  dosbox-x.reference.full.conf. The original file
  dosbox-x.reference.conf now contains common config
  options instead of all config options. (Wengier)
• The CONFIG command and Configuration Tool will now
  save common and modified config options by default.
  The -all command-line option (or "Save all options
  to the configuration file" checkbox) will force to
  save all config options. A new -mod command-line
  option is added to CONFIG command to save modified
  config options only, and a new -norem command-line
  option is added to not write remarks. (Wengier)
• Updated the Windows installer to default to the
  "typical" installation. For the full installation
  start menu items will be added for DOSBox-X builds
  copied to subdirectories. A new checkbox "Write
  common config options (instead of all) to the
  configuration file" is added which when checked
  will only write common and modified advanced config
  options to the config file. Furthermore, for both
  "typical" and "full" installations the Windows
  installer will now also copies the DLL files
  inpout32.dll (32-bit) and inpoutx64.dll (64-bit) to
  the DOSBox-X install directory for use with the
  direct parallel port passthrough feature. (Wengier)
• Improved Flatpak support for Linux. (rderooy)
• Improved message for the -help command-line option,
  adding for example -silent and -socket command-line
  options in the help messages. (Wengier)
• Added -silent command-line option to run DOSBox-X
  silently (without showing the DOSBox-X window) and
  then exit after executing AUTOEXEC.BAT. (Wengier)
• Fixed command-line option -socket not working for
  the null-modem feature. (Wengier)
• Fixed issue that aspect ratio not being respected
  in full-screen mode when a GLSL shader is enabled
  with an OpenGL output. (Wengier)
• Fixed toggle in the "Frameskip" menu group did not
  change when selecting a different option. (Wengier)
• Fixed shelling from programs may not work when the
  shell config option is set. (Wengier)
• The default country setting ("country" option in
  [config] section]) now defaults to auto-detection
  if possible, or 81 (Japan) in PC-98 mode. (Wengier)
• Increased the default maximum DOS files (adjustable
  from [config] section) from 127 to 200. (Wengier)
• Improved resetting with LOADLIN program. (Wengier)
• Improved Gravis Ultrasound (GUS) implementation to
  make it more accurately represent the GUS DMA state
  as expected by the running DOS software.
• The archive attribute will no longer automatically
  be applied to directories on non-Windows systems.
  This fixed issue with PLAYMIDI.EXE from Gravis
  Ultrasound when listing directories. (Wengier)
• Applied hack to allow the low DMA channel detection
  in the SB16 DIAGNOSE program to work. (Wengier)
• The default setting of the clip_paste_speed option
  has been changed from 20 to 30, which will help
  prevent lost keystrokes when pasting from the host
  clipboard for some programs. (Wengier)
• With Pentium CPU setting (cputype=pentium) DOSBox-X
  no longer reports FDIV bug by default. An advanced
  config option "report fdiv bug" is added to report
  such CPU bug when set to true. (rderooy & Wengier)
• Added support for the XDG_DATA_HOME environment
  variable for config directory in Linux. (rderooy)
• Added support for compiling with pcap for Windows
  MinGW builds. (Jookia)
• Added config option "windowposition" (in [sdl]
  section) to set the window position at startup in
  the positionX,positionY format. (tomba4)
• Added config option "raw_mouse_input" (in [sdl]
  section; SDL2 builds only) to bypass the operating
  system's mouse acceleration & sensitivity settings.
  Implemented by NicknineTheEagle.
• Added config option "startquiet" (in [dos] section)
  which when set to true will silence the information
  messages before launching Windows programs to run
  on the Windows host. A toggle menu item "Quiet mode
  (no start messages)" is added to the "Windows host
  applications" menu group in "DOS" menu. (Wengier)
• The menu "Show details" (under "Main") is renamed
  to "Show FPS and RT speed in title bar". (Wengier)
• Add menu group "Text-mode" under "Video" menu to
  change some text-mode related video settings, such
  as changing the number of rows and columns. A zip
  package named TEXTUTIL.ZIP is added to the Z drive
  that contains various utilities (such as CGA.COM,
  EGA.COM, 132X25.COM, 132X43.COM) to change current
  video setting from the command line. Also added a
  config option "high intensity blinking" which when
  set will display high intensity background colors
  instad of blinking foreground text. The menu item
  "Allow 9-pixel wide fonts" is moved from the menu
  group "Compatibility" to here. (Wengier)
• Added "Debugging" menu group under "Help" menu, and
  moved items from the "Video" Debug and "DOS" Debug
  menus and the debugger here (debug builds only).
  Also allowed to hide/show the console or debugger
  window in Windows debug builds. With the menu item
  "Console wait on error" checked the Windows console
  window will wait for the ENTER key before closing
  itself after an E_EXIT occurs. (Wengier)
