1998

1.11 (March 6)
Build | Source
Initial release, based on the NTDoom and ATB Doom. The version numbering follows from the Doom source code version numbering of 1.10.
  • Works under both Windows 95 and NT 4.0, although it works best under Win95.
  • Limited support for the Pause key. It works with some keyboards on some machines.
  • Supports any resolution compatible with your DirectDraw drivers.
  • Look up/down à la Heretic.
  • Translucency for selected objects.
  • Has a console with most of the functionality of Quake's. The only significant missing feature is Tab-completion.
  • Notarget cheat.
  • Command to kill all monsters in a level or yourself.
  • Can play MUS, MIDI, and MOD music.
  • Selected sounds are played in surround sound.
  • Doors that need keys to open are highlighted on the automap.
  • Automap now shows various statistics in addition to the level name.
  • True keybindings. Bind any key to any command or sequence of commands.
  • Intermission screen can now display your stats using absolute values rather than percentages.
  • A new more general demo format.
1.12 (April 7)
Build | Source
  • Some visual enhancements were made such as centering the menus and drawing borders around the status bar in higher resolutions.
  • Console commands can now be specified on the command line.
  • Removed some of Doom's limits such as VisPlanes, VisSprites, and 2S HOM.
  • Rewrote some of the inner loops in assembly. (There was some assembly in 1.11, but it never got used.)
  • New CVARs relating to mouse movement. (invertmouse, m_pitch, m_yaw, etc.)
  • Mouse movement doesn't get sluggish in high resolutions.
  • Automap colors are customizable.
  • Automap overlay and rotation are available.
  • Eight crosshairs.
  • Shoot up/down.
  • Alt-Tab and Pause work properly on all machines now.
  • The +jump command now works.
  • 25% and 75% translucency levels in addition to 50%. The translucency tables now get saved to disk, too, so they only need to be calculated once instead of every time the game is run.
  • The console font is now editable.
  • Near complete support for DeHackEd patches. (Only monster infighting and changing a few minor text strings are not supported.)
  • Sky height and position is now fixed for high resolutions. (It still wraps if you look up, but at least now if you look straight ahead, it never will.)
  • Weapon sprite is always drawn at the correct location. (It was being drawn too low in some resolutions like 400x300.)
  • New options menu, which includes a key configuration screen.
  • Stealth monsters.
  • New full-screen HUD.
  • And a few other things not worth mentioning separately.
1.13 (May 26)
Release thread | Build
  • Fixed some major bugs (that crashed the game) and other lesser bugs that were just annoying.
  • 3-D collisions for walking under and standing on other things.
  • The status bar can be scaled to the full width of the screen.
  • The screen mode can be selected from a menu inside the game.
  • ZDoom can run in a window on the desktop.
  • Better DeHackEd support. Only a few text replacements are not supported. Everything else works (including monster infighting which I haven't seen in any other port).
  • New features for level designers (see editing.txt for details):
  • Specification of next and secret maps on a per-map basis.
  • Specify sky texture on a per-map basis.
  • Use any lump in a wad as music for a map.
  • Give maps a custom name without using a DeHackEd patch.
  • Maps can be named anything (not just E?M? or MAP??).
  • Place any messages of any length between any two maps.
  • Hexen-style fog (of any color).
  • Ambient sounds — either point like Quake or global like Heretic and Hexen.
  • Automatic use of DeHackEd patches in PWADs.
  • No more DoomWikiLogoIcon.pngtutti-frutti for short textures of certain heights.
  • zdoom.wcf file for use with WadAuthor.
  • Rocket jumping. (One very important note about this: You need to be *in the air* when your rocket explodes for rocket jumping to work. This is different from Quake, and I will probably rewrite it for the next release.)
  • Dynamic palette flashes.
  • Supports stretching skies for freelook.
  • Larger freelook range.
  • Added tab-completion to the console.
  • zdoom.cfg is now the name of the default configuration file since Doom Legacy decided to start using config.cfg.
  • French language support. (Set language CVAR to "french".)
  • Player obituaries.
  • Unlimited ammo cheat (use g_unlimitedammo cvar).
1.14 (July 22)
Release thread | Build | Source
Bugs fixed:
  • The bunny scroller at the end of E3M8 no longer crashes the game.
  • The IDKFA cheat gives the proper amount of armor again.
  • Demo recording works again.
  • Telefragging works again.
  • Picking up the invulnerability sphere displays the correct colors now.
  • DeHackEd patches containing text replacements no longer crash the game.

  • The crosshair is finally accurate for aiming.
  • Autoaim is properly remembered each time you start ZDoom.
  • Switches in the Ultimate Doom that aren't also in the shareware Doom properly change their appearance when switched.
New features:
  • Players can choose their own colors and names. (Player setup menu is included).
  • 8-player support (untested but should work).
  • Miscellaneous internal code changes have been borrowed from the Boom source. (This does *not* mean that ZDoom supports Boom levels yet.)
  • Cheats, chat messages, and gamestate changes are now recorded in demos.
  • Single-player demos recorded with ZDoom are generally smaller than before.
  • Quake 2-style deathmatch flags.
  • Cheats (optionally) work in multiplayer games.
  • Mode X is now supported under Win95, so all the machines that couldn't run ZDoom in 320x200 before should be able to now.
  • Fewer conditions result in error messages that quit the game. (If you have Heretic, try this: Start ZDoom with -file heretic and go to the console and type "map E1M1".)
  • Keys can repeat in the console.
  • The console and chat mode now use the localized keymap set with the Keyboard control panel.
  • Messages at the top of the screen now break along between words instead of in the middle of them.

Bugs fixed are:
  • No more crashing about freeing a pointer without ZONEID when changing levels.

  • Monsters shouldn't teleport into each other anymore.
  • Improved support for international keyboards.
  • The skill level chosen for a new game is no longer ignored if the new game is started while a demo is playing.
Cosmetic changes:

  • Doublebindings.
  • Better analog joystick support.
  • 180 degree turn command for keyboarders.

  • Monsters stop attacking their target once it is dead.
  • EV_StopPlat() does not get stuck in an infinite loop if there are moving platforms.
  • Partially invisible players are drawn the proper colors (instead of green) if r_drawfuzz is 0.
  • If you are invisible, so are your muzzle flashes.

  • In high resolutions, weapon sprites meet the bottom of the screen.
  • Sounds will not cut out mysteriously when there is no reason for them to do so.

  • The sky gets DoomWikiLogoIcon.pnginverted when using the invulnerability powerup.
  • Implemented better z-checking code (from Heretic/Hexen).
  • Pain elementals will spawn one lost soul at a time instead of two inside of each other.
  • Bex patches that use thing mnemonics really do work now, and unknown bit messages aren't generated for regular DeHackEd patches.
  • Linedef type 134 for regular Doom/Boom maps requires a red key for activation (it was being improperly translated to require a blue one).
  • Monsters can activate secret lines when they cross them. (See Doom II MAP08).

New features interesting for wad authors:
1.17a (February 21)
Release thread
Mostly minor bug fixes, released because Herian 2 needed some of those fixes. There are a few new features, however:
  • If you have a skins/ directory in the same directory as zdoom.exe, every wad file in it will be automatically loaded when the game starts. This way, you don't have to load your skins by hand to use them.
  • New formatting options for text printed using ACS.
  • A code pointer to make monsters fire a railgun.
1.17b (March 17)
Release thread
Some minor bug fixes over 1.17 and 1.17a. It also loads faster because the sprite dimensions are not cached until they are actually needed. There are also some other internal changes in preparation for supporting Heretic and Hexen, but those don't affect the user yet.
1.17b1 (March 19)
Release thread
Bugfix release.
1.17c (May 5)
Release thread | Build | Source
  • Fixed game saving crashes on maps with wind/current effects.
  • In Boom deep water sectors, the underwater light and fog colors can now be set independently of the area above water.
  • Added nojump, allowjump, nofreelook, and allowfreelook keywords for use in MAPINFO lumps to control jumping and free look.
  • The random number seed now changes each time you run the program.
1.18 test 1 (June 30)
Release thread
  • Tweaked the optimized renderer for fifth-generation processors.
  • Added the following specials:
  • Added an additional parameter to the Transfer_Heights special.
  • Switched to the OpenPTC library for display.
  • Converted lots of code to an object-oriented C++ architecture.
1.18 test 2 (July 1)
Release thread
  • Fixed vertical aim clipping (BFG works again).
  • Fixed monster wandering.
  • Maps with mapthings of type 0 no longer generate warning messages.
  • Crushers that do no damage no longer act as if they inflict pain to actors.
  • The alias command lists aliases again.
  • Aliases are saved to the config file again.
1.18 test 3 (July 2)
Release thread
  • Removed unnecessary display mode switches.
  • Created a DCanvas class to encapsulate most 2D rendering.
1.18 test 4 (July 3)
Release thread
  • Fixed the "Bad DCanvas::CopyRect" problem introduced in test3.
  • Fixed sound sequences that should not be cut off when stopped (such as the standard doors).
1.18 test 5 (July 6)
Release thread
1.18 test 6 (July 10)
Release thread
  • Rewrote the MiniWikipediaLogoIcon.pngWu line drawer to look better (especially in overlay mode).
  • Stretched skies now get stretched horizontally as well as vertically.
  • Did an initial integration of the Cajun Bot 0.71 code.
1.18 test 7 (July 12)
  • Fixed handling of maps with scrolling walls.
  • Single player works again. In test 6, all games were considered either coop or deathmatch.
  • Disabled the bot thinking code in single player games, so you don't suffer a performance hit when not using bots.
  • Added some performance counters accessible through the stat command.
1.18 test 8 (July 20)
Release thread
  • Fixed a crash problem with the "burn" screen wipe.
  • Fixed a crash problem with playing non-assigned sound sequences.
  • Fixed a crash problem related to trying to shutdown the music subsystem twice.
  • If you try to add more coop bots than there are coop starts, the extra bot leaves quietly instead of ending the game.
  • Weapondrop is now a "server" CVAR, which it should have been in the first place.
  • Changed the nodetable file format to be more compact.
  • Bots can now be recorded in demos.
  • Bots work in multiplayer games. Still buggy. Spawning bots can cause consistency failures, and they can start spinning wildly.
1.18 test 9 (August 9)
Release thread
  • Fixed the "wild" bot spinning problem.
  • Commands like changemap that could make network games go out of sync should work properly now. The reason they would do that is closely related to the reason that the bots would start spinning.
  • Finished the serializer. Now savegames work. Hubs don't, because I haven't written the player travelling code yet.
  • Various other code cleanup.
1.18 test 10 (August 14)
  • Reimplemented hub travel.
  • Optimized R_MapPlane slightly.
  • Added fov command.

  • Bots are restored from savegames.
  • Fixed keyboard turning speed when -dup is used.
  • Network commands get executed only once when -dup is used.
  • In sectors with damaging floors and swimmable deep water, the damage will also be applied while the player is swimming and not just when the player is on the ground.
1.18b (September 15)
Release thread | Build | Source
Bugfix release.
  • Fixed crash when saving games with more than 1024 objects.
  • Fixed crash when loading a game without starting a new one first.
  • Reduced the size and frequency of pregame network packets, under the assumption that problems people were having using 1.18 on the Internet are a result of limited modem bandwidth.
1.19 (November 24)
Release thread | Source/Linux build release thread | Source
First official Linux build.
  • DeHackEd patches that set an actor's death sound to 0 without removing the A_Scream call no longer crash.
  • Fixed sync problems when playing with bullet puffs as particles vs as sprites.
  • Fixed friction when walking on the bottom of swimmable water.
  • Added Jeffrey Cuenco's fixes to get -host and -join command line parameters to work properly.

Bugfix release.
  • Sounds can be specified by full path now in SNDINFO and S_SKIN.
  • DECORATE replacement is more universal.
  • Added NecroMage's submission for bitwise/shift assignment operators for ACS. (Requires ACC 1.42+.)
  • Changed PlayAttacking2 to always use the melee state instead of different implementations per player and hard coding it to MissileState+1. Also changed PlayAttacking for the HereticPlayer to use the same animation as PlayAttacking2. Now the special handling for Heretic in the FireWeapon functions can be removed.
2.1.4r273 (July 29)
Release thread | Build | Source
  • Added partial emulation of Boom's TRANMAP by analyzing such lumps and extrapolating translucency level from them. This does not work for non-translucency effects that can be achieved with TRANMAPs.
  • Added a queryiwad_key cvar to control which key can force the IWAD selection box to appear. It can be either "shift" or "control". Any other value will disable its functionality.

2.1.6r346 (October 2)

  • Scaled 2D images are supported.
  • Dehacked max health usage defaults to consistency with other (Boom) ports.
  • A font parameter was added to A_Print.
  • Quoted strings in DECORATE can no longer span multiple lines without using the escape character (\) at the end of each line. This makes it easier to spot places where you unintentionally left off a closing quote and got an error several lines later.
  • A new writeini console command can be used to save the ini at any time, with any file name.
  • If the ini is write-protected when you quit, an error dialog now opens to let you know your settings could not be saved and gives you the opportunity to unprotect it.
  • Multiple stat displays can be enabled at once.
  • Several bugfixes.
2.1.7r524 (October 31)
Release thread | Build | Source
  • Alias commands can now do parameter substitution. If you have %x, where x is some number, in an alias command, it will be replaced by the appropriately numbered parameter passed when the alias is used, with %0 being replaced by the name of the alias itself.
  • A new MapMarker actor has been added that you can use to mark points of interest on the automap. If its first argument is zero, the map marker itself appears on the automap, otherwise it is drawn on top of any actor with a TID matching that argument. If the second argument is one, then the map marker will only be appear if the player has previously seen the sector it is in. You can use Thing_Activate and Thing_Deactivate on markers to turn them on and off. To make custom markers, all you need to do is subclass MapMarker with DECORATE.
  • Added the SetActorPitch ACS command to set an actor's pitch.
  • You can pass multiple jump targets to the A_Jump DECORATE function, and it will choose one of them at random if it jumps.
  • Using a TID of 0 with Thing_Deactivate, SetActorAngle, Thing_Spawn*, Thing_Projectile*, and Thing_Move will now operate on the activator.
  • The fifth argument for Line_SetIdentification can be used to set the high byte of the line ID.

2008

2.2.0r748 (February 15)
Release thread | Build | Source
  • This is the final version of ZDoom to fully support Windows 95 since later versions switched to FMOD Ex.
  • Added custom damage types, with monsters being able to have different custom pain chances, custom damage factors, and custom death sequence for each damage type. Also, damage-specific player pain and death sounds.
  • Custom damage color for palette flashes per player class.
  • Custom state labels. New states can be defined in DECORATE.

  • Drain, HighJump and Regeneration runes as powerups and used specific player sounds for their sound effects.
  • PowerQuadDamage and PowerQuarterDamage as more customizable PowerDamage and PowerProtection. These new powerups allow free customization of the damage modification per damage type by inheriting from these classes and setting specific values. Such derived damage/protection powerups will be considered as separate powers so that for example a QuadDamage and a DoubleDamage item can be stacked which would result in 8x damage.

  • Player.RunHealth property to expose the StrifePlayer's behavior of not being able to run when its health is below 10.
  • Customizable gravity per actor
  • New summonfoe console command, which is analogous to summonfriend but forces the summoned creature to be hostile instead.
  • Added two new MAPINFO flags to control what actor activates impact lines: MissileShootersActivateImpactLines (the current behavior) and MissilesActivateImpactLines (the original Hexen behavior).
  • More player water sounds: *dive (head goes below water), *surface (your head goes back above water), *gasp (getting air back after starting to drown)
