0.83.21

• Release notes for this version:
  https://dosbox-x.com/release-0.83.21.html
• Improved clipboard copying & pasting for different
  code pages including box-drawing characters in DBCS
  code pages. Also, for the J-3100 mode, the selected
  text will now be highlighted when you try to select
  text for copying. (Wengier)
• Improved IME support for Chinese/Japanese/Korean
  languages on Windows builds. (Wengier)
• Pausing the emulation will automatically release
  the mouse and prevent mouse capture. (Wengier)
• For Configuration Tool, a "..." button is added to
  properties which have limited numbers of values so
  that when clicking their possible values will be
  shown in a new dialog and can be selected directly.
  Also, more settings will be applied immediately when
  modified from the Configuration Tool. (Wengier)
• For Windows SDL1 builds, DOSBox-X will now try to
  prevent the Windows menus from separating into more
  than one lines due to small window width. (Wengier)
• If a scaler as specified in the config may not work
  as expected and if not forced, DOSBox-X will show a
  a message box asking whether to load it. (Wengier)
• Config option "pixelshader" now allows a shader file
  name without the .fx extension, or a shader file in
  the current directory. (Wengier)
• Added support for ENET reliable UDP as an option for
  modem and null-modem emulation. You can enable it
  with "sock:1" option for modems/null-modems that are
  connected with serial ports (COM1-COM9), such as
  "serial1=modem listenport:5000 sock:1" for COM1 to
  listen to port 5000 with reliable ENET UDP instead
  of TCP connection. The feature is ported from DOSBox
  Staging. (sduensin, GranMinigun, kcgen, Wengier)
• Added new command-line option "-o" for providing
  command-line option(s) if programs(s) are specified
  to start when you launch DOSBox-X. An example:
  dosbox-x program.exe -o "opt1 opt2". (Wengier)
• Added special properties to CONFIG command including
  "cd", "date", "errorlevel", "random", "time", and
  "lastmount" so that commands like "CONFIG -GET cd"
  and "CONFIG -GET errorlevel" will get current DOS
  directory and ERRORLEVEL value. The returned value
  will also be saved to %CONFIG% variable. (Wengier)
• Added "Enter Debugger Command" button to "DOSBox-X
  logging output" and "Code overview" windows (from
  "Debug" menu") for users to enter some debugger
  command(s) and see the result. (Wengier)
• Added debugger commands DATE and TIME to view or
  change DOSBox-X's internal date and time, using the
  same date and time formats as the shell DATE and
  TIME commands, e.g. "TIME 10:11:12". (Wengier)
• Added config option "badcommandhandler" (in [dos]
  section) which allows to specify a custom error
  handler program before error message "Bad command
  or file name" shows up in the DOS shell. (Wengier)
• Added config option "stop turbo on key" (in [cpu]
  section) which allows to automatically stop the
  Turbo (fast forward) mode when a keyboard input
  has been detected. (Wengier)
• Added config option "fat32setversion" (in [dos]
  section) which controls whether DOSBox-X should
  automatically set reported DOS version to 7.0/7.10
  when it's less than 7.0/7.10 and mounting LBA/FAT32
  disk images is requested. It defaults to "ask" so
  that DOSBox-X will ask in this case. (Wengier)
• Added config option "j3100colorscroll" (in [dosv]
  section) which defaults to "false" and allows the
  J-3100 version of SimCity and VGA version of the
  Toshiba Windows 3.1 to run, whereas CGA/EGA version
  of the latter requires a "true" setting. (nanshiki)
• Added config options (in "ethernet, slirp" section)
  "tcp_port_forwards" and "udp_port_forwards" for port
  forwarding when using the Slirp backend. (kcgen)
• Added code pages 737 (Greek) and 775 (Baltic) for
  the guest-to-host code page conversions. (Wengier)
• Added UTF8 and UTF16 commands to convert UTF-8 and
  UTF-16 text to view in the current code page. For
  example, the command "UTF8 < UTF8TEXT.TXT" will
  output converted text UTF8TEXT.TXT in the current
  code page, and for UTF16 command there are optional
  /BE & /LE options to specify endianness. (Wengier)
• Added support for DBCS characters located in UNC
  network paths of the form \COMPUTER\FOLDER\FILE
  on the Windows platform. (Wengier)
• Added hidden code page 951 for Big5-HKSCS encoding
  or Big5 Unicode-At-On (Big5-UAO) encoding. Config
  option "uao" is added in [ttf] section so that if
  set to "true" code page 951 will use the Big5-UAO
  encoding instead of the Big-HKSCS encoding, the
  latter being the default for CP951. If ChinaSea is
  enabled, ChinaSea characters will be used instead
  of original characters in these encodings. (Wengier)
• Added -nl option for MOUNT command to automatically
  find the next available drive letter to mount if
  the specified drive is already mounted. This allows
  multiple directories to be mounted when DOSBox-X
  starts with multiple [name] arguments. (Wengier)
• Added HISTORY command to display or clear command-
  line history for the internal DOS shell. (Wengier)
• Added ASSOC command to view/change file extension
  associations. You can define a command or program
  to open a file with a specific file extension, e.g.
  "assoc .txt=edit" to open .TXT files with the EDIT
  command when entering the .TXT file name from the
  DOS command line. Wildcards are allowed, such as
  "assoc .*=dir", although in such case exceptions
  including "assoc .com=com", "assoc .exe=exe", and
  "assoc .bat=bat" are probably desired. (Wengier)
• Commands CHOICE and COUNTRY are external commands
  that appear on the Z drive (Z:/DOS/CHOICE.COM and
  Z:/SYSTEM/COUNTRY.COM respectively) now rather than
  internal shell commands. COUNTRY command now also
  affects thousand and decimal separators. (Wengier)
• The internal Virtual Drive Z: can now be rescanned
  just like mounted local drives. (Wengier)
• You can now change most config options in [printer]
  section of the configuration for the virtual printer
  with CONFIG -set commands. (Wengier)
• Added missing ChinaSea characters in code page 950
  with ChinaSea/Big5-2003 extension enabled. (Wengier)
• Added support for Bash-shell completion for DOSBox-X
  on non-Windows platforms. (rderooy & FeignInt)
• Improved DBCS support for DOS commands including
  ATTRIB, ECHO, TYPE, MORE, and TRUENAME. (Wengier)
• Improved checking of segment limits. (joncampbell123)
• Mac OS X builds from now on will use an in-tree tool
  to replace dylib references in all executable files.
  XCode install_name_tool is no longer used, it became
  a hypocondriac and is sitting in the corner screaming
  about link edit data that doesn't fill a __LINKEDIT
  segment. It is once again possible to make Mac OS X
  ARM releases and to use dylib files from Brew doing
  so. (joncampbell123)
• Fix IPL1 partition choice debug message to actually
  show the partition index chosen, not the -partidx
  option variable, which if not given by the user, is
  -1 and was reported as a very large unsigned
  number. (joncampbell123)
• Fixed command-line options -starttool & -startmapper
  not showing messages from specified language file
  for Configuration Tool and Mapper Editor. (Wengier)
• Fixed an issue with RENDER_Reset function while
  loading previously saved states. (yetmorecode)
• Fixed E_Exit "RET from illegal descriptor type 0"
  when running DirectX diagnostic program (dxdiag)
  from a guest Windows 98 system. (Wengier)
• Fixed "parallel?=file openwith:xxx" not working if
  a file name is not provided. (Wengier)
• Fixed crash in the following config combination:
  output=ttf, machine=pc98, dosvfunc=true. (Wengier)
• Fixed Disney sound source connecting to parallel
  port not working in the previous version. (Wengier)
• Fixed NET command from Windows for Workgroups 3.11
  not working from the internal DOS shell. (Wengier)
• Fixed MODE command options like "rate" and "delay"
  not working if entered in upper cases. (Wengier)
• Fixed command-line parameters (when launching
  DOSBox-X) containing Chinese characters in code page
  950 not working in Windows SDL2 builds. (Wengier)
• Integrated commits from mainline (Allofich)
  • Improve BIOS FDD motor timeout counter, most
    notably for earlier PCs. Fixes a Chinese variant
    of Space Harrier.
