DOOM Retro v2.8.1 is now available. It may be downloaded here and a 64-bit version may be downloaded here. Its release notes are as follows:

• Optimizations have been made to further improve the overall performance and stability of DOOM Retro.
• Minor changes have been made to text that is output to the console.
• The current map’s title is now displayed again in the automap when the vid_widescreen CVAR is off.
• Further improvements have been made to the console’s autocomplete feature.
• A bug has been fixed whereby loading separate .deh or .bex files would cause DOOM Retro to hang.
• STBAR patches wider than 320 pixels will now be displayed correctly when the vid_widescreen CVAR is off.
• Restoring behavior present in Vanilla DOOM, exploding barrels will now trigger line specials.
• Weapons that have been altered using a DEHACKED lump to use the A_FireOldBFG code pointer will now fire in the right direction based on the values of the autoaim and mouselook CVARs.
• The correct amount of ammo is now taken from the player when entering take backpack in the console.
• A crosshair can now be displayed by enabling the new crosshair CVAR. It is on by default, but also requires the mouselook CVAR to be on and the autoaim CVAR to be off.
• If the iwadfolder CVAR is reset using either the reset or resetall CCMDs, the WAD launcher will try to find a common DOOM or DOOM II installation again the next time it is opened.
• The value of the facebackcolor CVAR is no longer applied to the background of the player’s face in the widescreen HUD.
