DOOM Retro v2.5.7 is now available. It may be downloaded here, and its release notes are as follows:

• Optimizations have been made to further improve the overall performance and stability of DOOM Retro.
• The icon of doomretro.exe has been redesigned.
• Elevators now move smoothly when the vid_capfps CVAR is a value other than 35.
• The dimensions displayed by the mapstats CCMD are now correct for extremely large maps.
• The vertical sensitivity of the gamepad’s right thumbstick has been reduced slightly when the mouselook CVAR is on.
• The spectre’s shadow will now pause if the console is opened during DOOM II’s cast sequence.
• Improvements have been made to the console’s autocomplete feature.
• XInput-compatible gamepads will now vibrate when the player is near an exploding barrel. The amount of vibration can be specified using the new gp_vibrate_barrels CVAR, which can be a value between 0% and 200% and is 100% by default.
• A bug has been fixed whereby a gamepad could continue to vibrate if the player had the chainsaw selected and then used the gamepad to start a new game or load an existing one from the menu.
• The vid_scalefilter CVAR will now affect the external automap correctly when the am_external CVAR is on.
• An evil grin will now be displayed in the status bar when the player uses the IDFA or IDKFA cheats.
• Minor changes have been made to text that is output to the console.
• Obituaries in the console now indicate if the player has a berserk power-up when killing a monster with their fists.
• The following changes have been made to all CVARs that specify a color:
  • They may now be set in the console to a hexadecimal string of the format #rrggbb. The CVAR will then be set to the index of the closest color in DOOM’s 256-color palette.
  • They may now also be set to one of the following color names: black, blue, brick, brown, cream, darkbrown, darkgray, darkgreen, darkred, gold, gray, green, lightblue, olive, orange, purple, red, tan, white or yellow.
• Any lumps in a PWAD between HI_START and HI_END markers will now be ignored.
• A bug has been fixed whereby when unbinding certain controls using the unbind CCMD, that control would then be bound again the next time DOOM Retro was run.
