xinvaders3d or xinv3d (1.37.0)
  * No Changes made. This is just an update to get beyond the
    unexpected confusion created between 1.31, 1.36, and 1.3.6
    version values. Reading earlier zip files and imports like
    Don's zip file Feb 2000 = 1.31, and HP-UX fixes 2022-03-01
    and then Debian's later 1.3.6 fixes it appears best to get
    beyond git tag 1.31 which might be stalling some automated
    release watcher program.? Also chose tag to be above 1.36.

 -- Joe Da Silva <digital@joescat.com>  2024 Apr 05

xinvaders3d (1.6.0)
  * Thanks to jamesbond3142 for fixing a segfault seen in 64bit

 -- Joe Da Silva <digital@joescat.com>  2023 July 16

xinvaders3d (1.5.0)
  * Renamed xinv3d to xinvaders3d to avoid package confusion if
    both programs loaded at same time on the same computer.
 -- Joe Da Silva <digital@joescat.com>  2023 Feb 23

xinv3d (1.4.0)
  * This started as a resurection of a Debian orphaned program
    'xinv3d' brought up to date and made buildable with current
    PCs. See URL: https://github.com/JoesCat/xinv3d
    Thanks to Debian's Ricardo Mones for suggesting rethreading
    from an earlier release. This version starts from earliest
    release found == version 1.31 based on an ibiblio tarball.
    NOTE: No CVS file system found therefore started fresh 1.31.
  * Imported code HP-UX (1.31) fixes, 2000feb07, unknown author.
  * Imported fixes and improvements, the moving of game text to
    gtext.h, and a detailed history added to README all done by
    Chris Butler for Debian's xinv3d ver{1.3.6-1...1.3.6-6}.
    NOTE: This import is smaller than a complete 1.3.6-6 clone.
  * Import xinv3d.6 manual written by Chris Butler for Debian's
    xinv3d 1.3.6-1 (but may be used by others).
  * Speed-up vector font drawing by changing multiplications to
    a few value increments. This benefits lower-powered CPUs.
  * Bug-fix for lower-right quadrant void of stars.
  * Timer-math bugfix that makes game seem to run very slowly on
    very fast computer even though game is running at thousands
    of frames per second.
  * Updated xinv3d to be built using autoreconf -i and automake.
    Added freedesktop and new icons (resolves Debian #738066).
  * Replaced old make. Bumped version number from 1.3x to 1.4.0

xinv3d (1.3.1)
  * Fixed drawing order. Objects were being drawn in reverse.
 -- Don Llopis <del23@users.sourceforge.net> 2000 Feb 07

xinv3d (1.3)
  * Many thanks to Thomas Boutell, he has contributed a
    Windows port of XInvaders 3D. See README.win for more
    information.
  * XInvaders 3D DOS port finished. XInvaders 3D will now run
    as a full-screen 640x480x8 DOS game. For windows users it
    will run in a DOS window just fine. I used DJGPP+Allegro
    to port it. See README.dos for more information.
  * Added Vector-fonts. All text graphics have been replaced
    with Vector-fonts. Gives the game a cleaner look.
  * New player blinking routine. Player now cycles through
    red colors, rather than being drawn each alternate frame,
    when a new level has been started.
  * New special effect: 1-UP indicator. When 7500pts have
    been reached a new life is indicated by a nice little
    vector 1-UP floating towards the player.
  * New alien-shoot missile routine. Aliens now shoot more.
  * New Distance-of-Point-to-Line routine, used for
    collision detection.
  * Added fix for FreeBSD systems, thanks to Peter da Silva.
  * Fixed ZONE_HEIGHT bug in game.c, which was generating bad
    pointers, thanks to Sam Bushell.
  * Cleaned up code, for portability reasons, thanks to
    Thomas Boutell for his help.
  * Left-Shift key is no longer being used.
 -- Don Llopis <dllopi01@fiu.edu>  2000 Feb 05

  * Cleaned up some more code.
  * Adjusted formation movement.
