DOOM Retro v2.3.6 is now available. It may be downloaded here, and its release notes are as follows:

• DOOM Retro is now compiled using Microsoft Visual Studio Community 2017 RC.
• Optimizations have been made to further improve the overall performance and stability of DOOM Retro.
• Changes have been made to the format of savegames and so are not compatible with previous versions of DOOM Retro.
• Minor changes have been made to text that is output to the console.
• A bug has been fixed whereby if the framerate was capped to a value less the display’s refresh rate by using the vid_capfps CVAR, it couldn’t be uncapped while the vid_vsync CVAR was on or without restarting DOOM Retro.
• The effect enabled using the r_shakescreen CVAR requires hardware acceleration. If the vid_scaleapi CVAR is "software", the screen will no longer momentarily freeze when the player is attacked and the r_shakescreen is not 0%.
• A warning will now be displayed in the console, and DOOM Retro will default to nearest-neighbor interpolation, if the vid_scaleapi CVAR is "software" and the vid_scalefilter CVAR is anything other than "nearest".
• The wrong map title is no longer displayed for MAP31 and MAP32 in some PWADs when using the BFG Edition of doom2.wad.
• A bug has been fixed whereby the MAPINFO lump in a PWAD could be parsed incorrectly and cause the wrong music to be played in a map.
• Music will now be paused if either the menu or console is open and the window loses focus.
• A crash will no longer occur when trying to spawn a spider mastermind using the spawn CCMD in DOOM Shareware.
