DOOM Retro v2.3.4 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.
• Minor changes have been made to text that is output to the console.
• The console now opens and closes faster.
• The game will no longer crash when opening the console on the title screen and using the mouse wheel to scroll upwards.
• Instead of toggling capping of the framerate at 35 FPS, the value of the vid_capfps CVAR is now the actual frames per second at which the framerate will be capped. It can be off, or between 35 and 1,000 FPS, and is 200 FPS by default. All interpolation is automatically disabled when this CVAR is set to 35 FPS. This CVAR has no effect if it is set to a value greater than the display’s refresh rate and the vid_vsync CVAR is on.
• Vertical sync with the display’s refresh rate now works correctly when the vid_vsync CVAR is on and the vid_scaleapi CVAR is "opengl".
• The vid_scaleapi CVAR is now "opengl" by default.
• The vid_scalefilter CVAR is now "nearest_linear" by default.
• The vid_vsync CVAR is now on by default.
• The following improvements have been made to HacX: Twitch ’n Kill support:
  • hacx.wad will now be identified correctly when it is loaded using the -iwad command-line parameter.
  • The health bar in the alternate HUD is now displayed correctly when the player’s health is greater than 200.
  • Using the A key to strafe left now works.
  • Windows are no longer shattered when using kill all in the console.
• The music will now be stopped if DOOM Retro crashes.
• A bug has been fixed whereby the music volume and sound effects volume were set incorrectly at startup in some instances.
• The text carets in both the save game menu and the console will no longer be displayed, and the skull in the menu will no longer animate, while the window doesn’t have focus.
• Objects will no longer be lit incorrectly in some rare instances.
• A bug has been fixed whereby certain secrets wouldn’t be counted in some BOOM-compatible maps.
• Sectors with multiple effects in some BOOM-compatible maps will now behave correctly.
• The weapon keys 1 to 7 will no longer momentarily fail to work after entering an invalid parameter for the IDMUSxy cheat.
