DOOM Retro v2.4.5 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.
• Sprites taller than 255 pixels are now supported.
• The map title in the automap is now positioned correctly when the r_messagescale CVAR is small.
• Frames from DOOM’s rocket launcher are no longer shown when firing the missile launcher in Freedoom.
• Entering the idmypos cheat will no longer cause a crash.
• Pressing the DEL key when in the save or load game menus will now delete the currently selected savegame.
• Minor changes have been made to text that is output to the console.
• The inverted gray color palette is now applied to the sky when the player has the invulnerability power-up, as originally intended.
• A bug has been fixed whereby blood splats would no longer be spawned after loading a savegame in some instances. Please note that because of this, savegames created with previous versions of DOOM Retro are not compatible with this version.
• Another 29 map-specific fixes, enabled using the r_fixmaperrors CVAR, have been applied to maps in the doom.wad, doom2.wad and plutonia.wad IWADs.
• The text caret shown when entering a savegame description in the save game menu is now always a vertical line using the dominant color of the character set. (Previously, the STCFN121 lump was used. In the DOOM and DOOM II IWADs this lump is a vertical pipe character, but in some PWADs it is replaced with a “Y” character.)
• The sound of the chainsaw will no longer cut off sounds made by the player.
• A bug has been fixed whereby translucent sprites would become less bright when the player had the light amplification visor power-up.
• A bug present in Vanilla DOOM has been fixed whereby homing rockets fired by revenants would randomly become non-homing, and vice versa, when loading a savegame or when pausing then unpausing a game.
