• A bug, inadvertently introduced in v1.6.1, has been fixed whereby the wrong colored keys would appear in the HUD.
  
• The default value for the saturation setting in doomretro.cfg has been changed from 0.75 to 1.00.
  
• The gamma setting in doomretro.cfg has been renamed to gammacorrectionlevel, and the alias off can now be used when it is set to 0.
  
• Blood splats will now appear in maps from PWADs that use a DeHackEd file or lump.
  
• The clipping of the bottom of things will now be updated when the sector they’re in changes to/from liquid.
  
• Spectres now have slightly lighter shadows than the other monsters, with fuzzy edges.
  
• Minor changes have been made to the values of settings in doomretro.cfg. The true/false aliases now appear as on/off, and the none alias now appears as a hyphen. Aliases yes/no may also be used.
  
• Setting the mouse sensitivity to 0 will no longer disable the gamepad as well.
  
• The range of gamepad sensitivity has been increased.
  
• Several minor changes have been made to the properties of pickups in HacX: Twitch ‘n Kill.
  
• The , and . keys can now also be used to strafe left and right, as they could in Vanilla DOOM. They are changed using the key_strafeleft2 and key_straferight2 settings in doomretro.cfg.
  
• Shifted characters are now allowed when entering savegame descriptions. (In Vanilla DOOM, pressing SHIFT + /, for example, would still display “/” rather than “?”.)
