DOOM Retro v1.6.7 has been released and may be downloaded here. This is a small point release and the changes are as follows:

• A bug has been fixed whereby DOOM Retro would crash at startup when trying to run in a screen resolution that wasn’t widescreen.
• DOOM Retro will no longer crash after successive presses of ALT + ENTER to switch between fullscreen and windowed modes.
• Ceilings that use liquid textures will now render correctly.
• An error will now be displayed at startup if a WAD file contains DeePBSP or ZDBSP nodes.
• The saturation setting in doomretro.cfg has been deprecated.
• A bug has been fixed whereby the shadows of dropped items weren’t also being mirrored when the mirrorweapons setting was true in doomretro.cfg.
• Weapons spawned at the start of a map are now also mirrored when the mirrorweapons setting was true in doomretro.cfg.
• Thanks to some excellent coding from entryway and kb1, Vanilla DOOM’s “long wall error” has been fixed.
• Further optimizations have been made to improve the overall performance and stability of DOOM RETRO.
• Teleporters in Back to Saturn X are now drawn correctly in the automap before they have been triggered.
• Whether the automap is active or not, and any automap marks, are now saved in savegames. (Note that this change breaks savegame compatibility with previous versions of DOOM Retro.)
• A header comment has been added to the top of doomretro.cfg, with a note advising to “go to http://wiki.doomretro.com for information on changing these settings”.
• The FPS counter displayed when –DEVPARM is specified on the command-line now won’t be hidden when taking a screenshot, and will continue to update when in a menu or the game is paused.
• Diminished lighting from the player has been enhanced.
• Bloodsplats are now only spawned at the same height as corpses as they slide.

DOOM RETRO v1.6.6 has been released! It may be downloaded here. This is yet another small point release and the changes are as follows:

• The new liquid animation that was introduced in DOOM Retro v1.6.5 has been improved upon such that the entire textures of the sectors will now also rise and fall, rather than just their edges.
• Due to this change in animation, the floating objects in liquid sectors now rise and fall in sync with each other and the sector.
• The bottom of objects in liquid that don’t float (such as monsters and barrels) will now be clipped in sync with the rise and fall of the liquid.
• All liquid sectors are now animated, avoiding issues where one liquid sector would be animated, but another liquid sector adjacent to it wouldn’t be.
• A bug has been fixed whereby the liquid animation was stopping the player and/or monsters from being able to enter certain areas of some maps.
• The brightmap for the COMP2 wall texture has been fixed.
• A bug has been fixed whereby other monsters could infight with Arch-viles.
• The teleporter texture used in Back to Saturn X no longer animates like a liquid.
• Savegames will now be placed in the savegames\DOOM2.WAD\ folder rather than the savegames\unknown.wad\ folder when NERVE.WAD is loaded.
• The player’s weapon is now recentered after teleporting.

DOOM Retro v1.6.5 has been released and may be downloaded here. This is a small point release and the changes are as follows:

• Many optimizations have been made to further improve the overall performance and stability of DOOM Retro.
• A bug has been fixed whereby secret sectors that lower and change their texture may not be displayed in the automap correctly.
• Decorative corpses spawned at the start of a map are now randomly mirrored as intended.
• A bug has been fixed whereby the player sometimes wouldn’t trigger a teleport when running over it in some instances.
• Changes have been made to how lighting is calculated.
• Liquid sectors, and the partially submerged objects that are on them, now animate up and down. This feature may be disabled by changing the animatedliquid setting in doomretro.cfg to false.

• A bug has been fixed whereby objects on a sector that lowers and becomes liquid wouldn’t update immediately (that is, the bottom of their sprites wouldn’t be clipped, their shadow wouldn’t be removed, and blood splats wouldn’t be removed either).
• Blood splats that are spawned around decorative corpses at the start of a map are now spawned in a more natural-looking circular pattern, and may also be offset slightly from the corpse to give the impression that the corpse may have slid.
• Blood splats that are spawned when crushing a corpse are now also spawned in a circular pattern.
• The positions of shadows for several monsters have been improved.
• The total amount of blood splats that can be spawned when a corpse slides across the floor has been doubled.
• The total amount of blood splats that can be spawned when a corpse slides across the floor is now saved in savegames. This breaks savegame compatibility with previous versions of DOOM Retro.
• Blood splats that are spawned around decorative corpses at the start of a map now come from this same total.
• A bug has been fixed whereby it was possible for the screen to switch between the TITLEPIC and CREDIT lumps before wiping the screen after the player selects a skill level in the menu to start a new game.
• The top and bottom edges of Spectre shadows are now “fuzzy”.
• The top and bottom edges of Spectre shadows are now “fuzzy”, and also lighter, in DOOM II’s cast sequence, to match how they appear in the game.
• A savegame slot that isn’t empty is now automatically selected in the load game menu if the player previously exited the save game menu while a savegame slot that is empty was selected.
• The screen will now flash the same amount for keycards and skull keys as for other pickups.
• The window can now be resized when in widescreen mode.

• The textures PLANET1, SW2BLUE and SW2MARB now have brightmaps.
• NERVE.WAD will now be automatically loaded if DOOM2.WAD is selected in the WAD launcher and there are also one or more PWADs selected that don’t contain any map data.
• The translucency of blood splats has been reduced slightly, and their edges are no longer softened.
• Green blood splats are now slightly darker.
• A bug has been fixed whereby some shootable switches would only work once.
• The edges of shadows are now black when the translucency setting in doomretro.cfg to false.
• The sfxvolume and musicvolume settings in doomretro.cfg will no longer round down to 0% when set to 6%.

In celebration of DOOM’s 21st birthday (and DOOM Retro’s first!), point release v1.6.4 is now available for download. Here’s a list of the changes it brings:

• Several optimizations have been made in an attempt to further improve the overall performance of DOOM Retro.
• DeHackEd files (*.DEH and *.BEX) are now displayed and can be loaded in the WAD launcher. CTRL-click to select them along with the WAD file(s) you want to load.

• Problems with movement of the mouse have been fixed when starting DOOM Retro in windowed mode.
• Panning when follow mode is off in the automap is now back to working correctly.

• The player’s view will no longer be lowered further due to the footclip setting when standing in a self-referencing sector.
• Improvements have been made to switching weapons using a gamepad.
• For non-widescreen displays, the status bar is no longer displayed when in the automap if it isn’t displayed during a game.
• A bug has been fixed whereby the screensize setting was being reset at startup for non-widescreen displays.

• The menu may still be opened with the gamepad’s START button if gamepad_sensitivity has been reduced to 0.
• A bug has been fixed whereby the help screens wrongly indicated that the A and D keys were used to turn rather than strafe.
• The overall gamepad sensitivity has been increased even more, and the default of gamepad_sensitivity has now been doubled from 16 to 32.

• Several internal optimizations have been made in an attempt to improve the overall performance of DOOM Retro.
• Decorative corpses are now randomly mirrored when a map is loaded.
• A potential overflow has been fixed if there was more than 32 characters in a savegame description.

• A bug has been fixed whereby extreme slowdown would occur if a large amount of monsters (and blood splats) were on a moving sector.

• The messages displayed when the player picks up ammo are now accurate, since the amount can vary depending on the skill level chosen and/or whether a monster dropped it or not.
• A bug has been fixed whereby monsters were not always remembering their last target when attacked by something else. This would affect monster infighting in some instances.
• Widescreen mode is now supported in windowed mode. Rather than displaying pillarboxes, the window will expand and contract horizontally as necessary when toggling widescreen mode on and off.

• Smoke trails are no longer applied to Revenant non-homing rockets by default.
• Instead of just on and off, the smoketrails setting in doomretro.cfg has been changed to allow smoke trails to be enabled or disabled depending on who fired the projectile. The setting can be any combination of the following flags: player (smoke trails for player rockets), revenant1 (smoke trails for revenant non-homing rockets), revenant2 (smoke trails for revenant homing rockets) and cyberdemon (smoke trails for cyberdemon rockets). The default is player|revenant2|cyberdemon.
• A bug has been fixed whereby pressing the CAPSLOCK key on the titlescreen will cause the use of the key to then become inverted (that is, turning CAPSLOCK on would turn “always run” off, and vice versa).
