DOOM Retro v3.3 is now available, in both 32 and 64-bit varieties. Its release notes are as follows:

• Optimizations have been made to further improve the overall performance and stability of DOOM Retro.
• If a mistyped filename is entered in the WAD launcher (for example, doot.wad instead of doom.wad), DOOM Retro will now try to find the closest match.
• If hardware acceleration is unavailable, DOOM Retro will now change the vid_scaleapi CVAR to software and scale each frame accordingly, rather than simply crashing during startup.
• DOOM Retro is now fully MBF-compatible, as support has now been added to BOUNCES and TOUCHY flags in DeHackEd lumps.
• Further improvements have been made to the console’s autocomplete feature.
• Minor changes have been made to the character set used in the console.
• Minor changes have been made to text that is output to the console.
• A level 2 warning will now be displayed in the console if there’s a locked door with no keycard or skull key provided in the map to open it.
• The visual glitch displayed when input is selected in the console while it is opening or closing is now fixed.
• Once the condump CCMD is used to dump the current contents of the console to a file, every line of text that is output to the console thereafter will continue to be dumped to that same file automatically.
• The r_blood CVAR can now be green, causing all blood spilled to be green.
• The episode CVAR will now be updated if the player finishes episode 4 and SIGIL is loaded.
• The thinglist CCMD now indicates if a thing has been dropped by a monster.
• A crash will no longer occur when a monster tries to make a noise and the -nosfx or -nosound parameters are specified on the command-line.
