• extended all fonts to be capable of handling all European languages which are in common use.
• First stage of DSDHacked support. Tested only with crusader.wad for now.
• The build system was transitioned to optionally use vcpkg, which allows building GZDoom on Windows by running a single batch file.
• WebP and QOI support for textures.
• sanitized the light mode selection to make it a first class mapping feature by separating map dependent light mode setup from performance related user preferences for the default setting.
• Linux: GTK startup now offers all the options of the Windows variant
• lots of new ZScript features.

Details

• Changed the variable type of Crossed3DWater. Seems like there was some kind of oversight. Crossed3DWater is an F3DFloor pointer, not sector_t.
• Add ZScript constants used by FallAndSink
• Switch to miniz from zlib
• fix for Genesis of Descent E1M2, which is impossible to complete on ITYTD/HNTR. I had to decompile the ACS script to figure out what was going on, basically at one point you get locked into a room and have to kill exactly 3 enemies with TID 215 for the door to unlock. One of these is a Baron tagged for only Medium and Hard, in his place is an Imp #1184 that has all the right script setups but is not set to appear on any difficulty. The fix is to simply have this imp appear on Easy.
• fixed the overlapping sector handler in hw_fakeflat.cpp. This picked the wrong plane as the proper texture cutoff.
• fixed: The UDMF loader did not adjust the floor/ceiling overlap state after processing UDMF sector plane properties.
• fixed: EV_DoDonut checked the wrong compatibility variable and missed all map specified flags.
• Fix gameinfo load from same directory as file containing gameinfo lump
• validate partner seg index in LoadGLZSegs before using it
• added compatibility handler for Phocas Island 2 MAP01.
• fixed doublebind check with automap. For the automap C_DoKey gets called twice, once with the automap bindings and once with the regular bindings and doubleclicks.
• clear the Dehacked string table after passing it to GStrings. For some reason std::move does not work here so make sure it won't stick around.
• stop all cutscenes before the ENDOOM screen.
• fixed: Boom's generalized crushers must stop 8 units above the floor. This required changing the special, so a new one was added to avoid altering Generic_Crusher.
• Fix a very rare crash with complex Polyobjects
• add support for not localizing some text functions, and modify menu text fields to use this
• let Dehacked set the implicit missile flags.
• fix ammo consumption of powered up Phoenix Rod.
• add unexplored secret color for overlay automap to the menu
• made all FileReader implementations 64 bit capable.
• added a nomirrors compatibility handler and applied it to Conf256's CONF55 map. This is for disabling broken plane reflection setups.
• When compat_floormove is enabled prevent sector floor from lowering if a thing is stuck in the ceiling (vanilla behavior)
• fixed M_GetSavegamesPath for Linux.
• Add Inventory::ModifyBob and Inventory::ModifyBob3D
• Expose OF_Transient to actors as bNoSaveGame
• add StartGameDirect function
• fixed: MBF21's BOSS flag implies NORADIUSDMG.
• fixed: For Dehacked, A_CPosAttack needs to use a hard coded attack sound. This discrepancy is ancient, so the approach used for the shotgunner does not work here and some hacks are needed to remap the function only for Dehacked.
• implemented the remaining dynamic structures of dsdhacked
• dsdhacked: Allow dynamic creation of new actors
• dsdhacked: allow dynamic creation of new states.
• add float.equal_epsilon and double.equal_epsilon
• Allow building gzdoom with Vulkan with either X11 or Wayland WSI integration through CMake options
• use stb-image for JPEG decoding because the old library provides no advantage over it.
• Allow disabling colors for NameAllKeys
• avoid high stack usage in anmtexture.cpp
• added DSDA's passover/nopassover keys to the MAPINFO parser.
• use a string pool to store all filenames and in the file system. this avoid lots of small allocations for data that will released in bulk later.
• use the lump cache directly for FileData. This was the final puzzle piece to allow using memory mapped files in the future.
• use better hash function in the file system. This is djb2 which is supposedly one of the best string hashing functions around.
• rewrote dir CCMD using ScanDirectory and avoiding I_ChDir entirely.
• use ScanDirectory in all places where the findfile API was used.
• WebP image support
• added safeguards against very early access to console variables in Cocoa backend
• Add support for QOI image formats
• block the centerview CCMD if the player has TOTALLYFROZEN. This is deliberately done this way, instead of placing the check inside PlayerPawn::CheckPitch, because there may be other situations where we don't want to block the centering function (APowerFlight::EndEffect being one such case)
• replaced zstrformat with stb_sprintf.
• A_Chase CHF_DONTLOOKALLAROUND
• Add Weapon::ModifyBobLayer , Weapon::ModifyBobLayer3D and Weapon::ModifyBobPivotLayer3D
• allow explicit casts between vectors of different underlying types
• Fixed BlockingLine giving erroneous results
• add CountSectorTags/CountSectorTags/CountLineIDs/GetLineID
• Exported reflection functionality. Localized reflection code to a single function. Fixed an error where NOSHIELDREFLECT was being checked on the wrong Actor. Fixed an oversight where MIRRORREFLECT was checking for valid target despite not needing one.
• Added ShadowAimFactor and ShadowPenaltyFactor. These properties allow to specify how much an actors' aim is degraded when shooting at a shadow actor. And how much the shadow actor itself affects the shooters' aim, respectively.
• Added MF9_SHADOWAIMVERT. This flag causes the vertical aiming of monsters to also be affected when they aim at shadow actors.
• Added MF9_SHADOWBLOCK. Actors in the line of fire with this flag trigger the MF_SHADOW aiming penalty. The shooter needs to have MF9_DOSHADOWBLOCK to check for actors with this flag.
• Added MF9_SHADOWAIM. This flag allows actors with MF6_SEEINVISIBLE to still get an aim penalty by trying to shoot at a shadow actor.
• Added damage property to earthquakes.
• Added damage and thrust multipliers to quakes.
• Added QF_DAMAGEFALLOFF. This flag makes it so that the damage and actor thrusting of earthquakes fades with distance like the screen shake effect does.
• Added (XF/RADF)_CIRCULAR. This flag makes explosions use a spherical radius, instead of a cubic one. Only took almost 30 years.
• Added (XF/RADF)_NOALLIES. This flag allows explosions to not harm any actors that are friendly to its' source.
• Added (XF/RADF)_THRUSTLESS. This flag allows for explosions that do not thrust any of the actors caught in the blast.
• Allow custom MessageBox menu selector
• Individual Joystick Enable/Disable Toggles
• add QualifiedName to VMFunction and allocate these static names from the class data memory arena instead of using FStrings.
• null pointer type checks in the VM added to avoid crash on bad codegen.
• Expanded Service's Get functions to pass in name parameter.
• Added GetName(UI/Data) to Service class.
• make all legacy light modes except 'Doom' and the software rendering emulation MAPINFO only. A CVAR still exists for testing but its value won't be saved to the config.
• MAPINFO can not enforce any of the two software light modes, as low end users require the option to change this to the 'performance' setting.
• changed lightmode menu options: user can only select between "performance', 'software' and 'vanilla'. 'performance' is the old 'Doom' mode which is still needed to speed things up on low end hardware.
• fix the ammocount parameter in Weapon.CheckAmmo
• fix UMAPINFO boss action clearing. This did not handle the case where the actions were cleared without adding new ones and also did not clear the MBF21 boss action flags.
• remove memory leak in A_ChangeModel
• made some changes to vectors.h so that it can be used without the floating point function replacements.
• Add Voodoo Zombie Compatflag
• remove vid_gpuswitch and all its handling; it is only as of now useful in old versions of Windows 7/8/10 which are no longer supported
• added MaxEffectTics field to Powerup
• adapted font system to properly handle Turkish. Those i's are really messy, especially when dealing with allcaps or pure lowercase fonts.
• made D_WriteUserInfoStrings memory safe.
• Fix TArray allocating 0 bytes in constructor
• Add dynamic lights to software slope drawer
• use uniform buffers for dynamic lights everywhere. Branching on SSBO content does not work that well on NVidia so it is better disabled. So far only implemented for OpenGL Vulkan needs more work.
• Fix Software Slope Rendering for non-1.2 pixel ratios
• add the flags MINVISIBLE and MVISBLOCKED
• Extend pseudo-generics system used by maps to dynarrays
• add RedirectCVAR directive for loading alternate maps based on a Bool CVAR setting

• Fixed SpawnForced not respecting the minimum declared in zspecial.acs. (https://forum.zdoom.org/viewtopic.php?t=77027)
• Exported LinePortals to ZScript
• cleaned up the pitch management in the sound backend. This now treats all pitch methods equally instead of the preferential treatment of Doom's original pitch hack. Most importantly, the sound channel now stores the pitch as a floating point value instead of 9.7 fixed point.
• snd_pitched now also gets checked in the sound engine, not the low level interface.
• Fix Y position of characters in monospace fonts
• Added all of the missing player cheats to the SetPlayerProperty special.

• Fixed a bug where static events would fail to halt propagation.
• Fix diffuse-only material shaders not applying.
• Add sv_noplayerclip to allow players to walk through and shoot each other (only in coop)

• changed CreatePalettedPixels to allow return of static pixel data without reallocation and copying.
• fixed buffer size checks for raw textures.
• Prevent important messages from being accidentally filtered.
• Updated the WOPN banks collection
• Added FlyBob Multiplier for Player
• Added WaterClimbSpeed Property to Players
• Fixed custom screen height and width not saving.
• Additional lock-related ZScript functions.
• Key.IsLockDefined: returns whether a lock number is valid (can be unlocked) or belongs to a "does not work" door.
• Key.GetMapColorForLock: returns the automap color for a lock number (or -1 if the lock isn't valid).
• Key.GetMapColorForKey: likewise, but for a specific key.

• fix OpenGL ES selection on the windows startup dialog
• Multi-Assign Declarations

Inportant note to Windows users:
GZDoom 4.9.0 changes where gzdoom.ini is stored. Unlike older versions this one will always prefer the system's user folder and place the INI in Documents/My Games/GZDoom if no INI is found. This was done to bring handling in line with current guidelines and to make it easier for commecial games that often get installed into a folder without write access. If you still want to store the INI in your game folder you have to create an empty file called GZDoom_portable.ini there before launching. If you still have an old INI in your folder, GZDoom will ask what to do with it, you can either move it to the user folder or convert to a portable install.

Change of savegame storage
This version introduces per-IWAD savegame folders. If you have old savegames you still intend to use, please wait with the update until you can safely delete them.

Highlights

• IQM bone model support
• textured particles

Details

• added target check to A_MaulerTorpedoWave.
• fixed: P_SpawnMapThing may not call playsim code.
• added PARAM_NULLCHECK to the block iterator creation functions.
• added [[noreturn]] to several functions that always throw exceptions.
• Particle Rolling
• Add Textured Particles
• Add GFF_NOEXTCHANGE to Phasing Zorcher flash. The Plasma Rifle does not light the player's sprite, so we must assume the Phasing Zorcher also should not.
• Fix HUD models not drawing if MODELDEF has been changed with A_ChangeModel
• Fix inconsistent distance and hit position on traces that skip everything.
• Fix canvas textures getting clipped by wrong scissor box
• Fix vulkan backend clearing the canvas textures to undefined contents
• made DMover and subclasses non-abstract so they can be inherited from.
• added option to show hub and episode names on the alt HUD.
• reworked CVARs to not use a linked list and to be initialized manually.
• marked a few Printf calls in critical error paths as PRINT_NONOTIFY.
• fixed: R_LoadVoxelDef did not fully initialize the voxel descriptor it creates.
• don't crash on null pointers in V_GetFont.
• zero the velocity of crunched sprites. Since their size is zeroed, they are no longer subject to collision detection and may slide out of the level otherwise.
• don't crash when destroying incomplete textures. This can happen during TEXTURES parsing in case of an error.
• try to keep the engine stable for as long as possible if a VM exception occurs in OnDestroy while running a cleanup. This will still crash, but run long enough for the exception message to be visible.
• fixed F2DDrawer::SetClipRect.
• added vanilla donut handling to compat_floormove.
• Fixed: voxel models pitch/roll properties weren't initialized correctly
• Added QF_SHAKEONLY. The QF_SHAKEONLY flag changes the behavior of earthquakes with a damage radius, so that they only shake actors around, without also harming them.
• Added QF_AFFECTACTORS. The QF_AFFECTACTORS flag makes the thrusting and harming of damaging earthquakes also affect monsters. Monsters with DONTTHRUST will not be flung around by earthquakes.
• Added the QF_GROUNDONLY flag. The QF_GROUNDONLY flag makes earthquakes only shake the player while they are standing on the ground.
• fixed DrawLine commands by giving them a consistent floating point interface.
• heretic: e2m7 - missing texture
• fixed direct native interface for Draw(Thick)Line.
• fixed: The main loop never checked the cutscene flag for disabling wipes.
• Sync movie video playback to the audio, when possible
• Fix washed out colors in Vulkan HDR mode
• normalize the timer with the app start, not the epoch. This ensures smaller values and less wraparounds with integer values in scripts.
• un-deprecated the integer MSTime variant. Due to undefined downconversion rules from double to int, there is no way to safely downcast the return from MSTimef, meaning the function is completely useless for retrieving integral time stamps.
• added Harmony ENDOOM screen.
• added a config getter to the interface.
• moved language CVAR to backend.
• handle menu customization via callbacks.
• move hud scale CVARs to the backend.
• handle autoload flags in startup through function parameters instead of directly accessing the CVARs.

• fixed: all script methods adding an object to a dynamic array must perform a write barrier.
• add freezetics actor property
• allow notification of actor goal is reached inside of a SECF_NOATTACK sector
• GLES2: Fix anistropic filtering

- added the cutscene system from Raze

Details
- the chat should use the console's scaling, not the one for the messages printed with the small font.
- fixed auto-scaling for console.
- removed all vid_fps offsetting. To compensate there is now also a "stat fps" which displays the FPS rate in the lower left corner. This had to go because unconditionally altering positions was causing problems with custom HUDs.

- Made CanCrossLine opt-in by requiring the CROSSLINECHECK flag.
- Added CanCrossLine virtual for actors.Called last after all other line checks occur. Returning false means the actor cannot cross that line.

• ReadThisMenu / MenuDelegate overriding.

The major new addition is a new GLES2 backend, meant to improve performance on low end hardware. This was written by emile_b for the Android port but backported to the mainline for old hardware support.
Please note that this backend removes some non-essential features to increase performance, like the entire postprocessing or advanced lighting features like specular or PBR.
Our tests show no performance gains on modern hardware capable of Vulkan, so is not recommended to run it on such systems - it is solely meant for old hardware that have performance issues with the modern GL backend.
On older hardware capable of supporting OpenGL 3.3 our measurements show that performance is generally on par with LZDoom.

Furthermore, to make the new backend available to 32 bit users as well, GZDoom 4.7 will exceptionally provide a 32 bit build as well, but please be aware that it depends on the survey's result whether this will see continued maintenance, as user share was already extremely low two years ago.

The survey has been re-enabled for this version so that we can get some information about how the state of systems being used for GZDoom has developed over the last two year. This is mainly due to the addition of the new GLES backend for old hardware, so we can get an overview of how much of this hardware still exists and how future support needs to be handled. We would like to ask as many users as possible to participate, so that we can make the right decisions based on the information we obtain. Like previous surveys this does not collect any private information - all it sends is basic info about the operating system, the number of CPU cores, the name of the graphics card and supported OpenGL/Vulkan versions.

Highlights:

• Widescreen graphics for Strife
• new GLES backend for better performance on OpenGL 3.3 and early 4.x hardware.

• added an OnDestroy method to Shape2D so that its users can explicitly free the data it holds. In this case it is very important to care about management, because this class will hold GPU-side buffers!

• prevent appearance of dangling pointers in corpse queue

• fixed format specifier compilation warnings

• fixed: splashes need the MOVEWITHSECTOR flag.

• better sprite shadow control

  • exclude sprites which are not either opaque or use regular blended translucency from casting shadows.
  • exclude wall and flat sprites from casting shadows.

  In both of these cases the shadow math is unable to produce anything useful that doesn't look off.

• fixed: shadow alpha for translucent objects was not correct in the hardware renderer.

• tweaked shadow code a bit.

  • let CASTSPRITESHADOW act as an override for render style checks. If this is set we can assume that a shadow is desired regardless of style.
  • reordered code to do the more costly checks only when needed.

• fixed brightmap definitions for the SpiderMastermind.

• add player setup to simple options menu

• do not precache unreferenced textures

• added map option to disable shadowmaps. (Prompted by 'Hurt' which has > 4000 lights and runs into both performance issues and unpredictable light selection for the limited amount of shadowmap slots.)

• language update

• For all of Doom's fullscreen images there's now widescreen versions provided. The other games are still being worked on and will be added later when they become available. All new images were created by Nash - this does not use any of the versions from the Unity port.
• A simplified options menu is now available for quick setup of the important settings.
• New keybindings presets. Users can now choose between the classic layout and a WASD-based one
• Menu and intermission screen now scale to the original Doom.exe's layout by default.

fixed ZScript compiler crash with dereferencing null pointers
moved the frame rate drawer out of DFrameBuffer.
did a bit of cleanup on DFrameBuffer, most notably taking GetCaps out of it. With the old softpoly renderer and OpenGL 2.x being gone there is no more need for such complex handling, it is now a single function in d_main.cpp.
Added MTF_NOCOUNT to spawn flags
split voxels.cpp into a backend and a game dependent part.
made FModelRenderer game independent - the 3 functions in question may just be global functions instead.

added validation of game skill when changing a level
fixed potential crash on intermission cast screen
set all texture IDs after finishing the initial texture manager initialization. As it turned out, not all textures have a valid ID at that point so it needs to be redone.

fixed setup of IPK3's where all content is in a subdirectory.
fixed texture layer management so that each material layer can decide for itself if it wants to allow upscaling.
rewrote the hardware texture precacher to use the new texture management to properly track the data to delete.
store the Vulkan descriptor sets in the material - where they belong! Having them in the base texture object was a major maintenance issue.
store the material layers in reference counted pointers in the FGameTexture object.
major refactor of texture upscaling control. All decisions were done deep inside the texture creation code, leaving zero options to the higher level code for controlling the feature.
moved the decision whether to upscale textures up one level in the function chain. Still not the perfect place, this should be decided before creating the texture, not in the middle of the process.
disabled the selective texture cleaning in the precacher. The logic here turned out to be a serious blocker and needs to be rethought.
allocate the sprite positioning info on demand only.
Moved the raw texture handling into the texture manager as well.
moved the front layer hack for Hexen's skies to the texture manager.

use FGameTexture instead of FMaterial for texture tracking in the hardware renderer.
moved the sprite positioning info out of FMaterial back into FTexture.
scale the automap parchment to clean 320x200 dimensions.
made 'supportRemap0' an image property so that the handling for this can be taken out of the actual texture class by just providing a replacement texture for the skies.
decoupled the software renderer entirely from FTexture - it will only look at FSoftwareTexture now, all access to the texture manager has been wrapped.
texture code refactoring to consolidate multiple textures referencing the same backing image.
handle brightmaps in the main shader instead of keeping separate instances around.
added detail and glow layers from Raze.
fixed material setup which could not guarantee that everything was initialized correctly.
for warped textures, warp all layers. With this brightmaps finally work on warped textures.
fixed detection of standalone IWADs
let FSkybox inherit from FImageTexture to simplify the redirection of the base image for the software renderer.
fixed text size calculations in the status bar.
fixed: Setting 'noallies' on the level cleared the player's friendly flag.

fixed conditions with SND_PlayerReserve flag
added global variants of the main 2D-draw functions taking an F2DDrawer as their first parameter.
separated the Doom specific parts of the ZScript parser from the core into a subclass.
separated the Doom specific parts from the compiler backend into a separate file, these parts now get invoked via callback hooks.
put the state pointer serializer in a virtual function so that types.cpp can operate without any knowledge of Doom states.
split the serializer in two to keep the Doom specific parts out of the main file.
split the TObjPtr serializers into a separate file to avoid polluting everything that needs to use the serializer.
took InitializeDefaults out of PClass and moved it to PClassActor. Like so many other parts, this created a hard dependency of the low level code on very invasive game content.

use translation slot 0 for reserved content, like font translations.
major dependency reduction of the texture system.
moved some data needed by the texture system into palettecontainer.cpp.
split animation management out of the texture manager into a separate class.
moved game specific data out of the sound backend. In Raze I already had a user data array for that so this gets used here, too, now.

separated the game-dependent music lookup parts from the core player.
reduce backend's dependency on game state by using callbacks.
merged FPalette and PaletteContainer.

uncouple console's cursor blinking from the game ticker.
c_dispatch header cleanup and splitting of gamestate into a separate header, to avoid polluting low level code with game specific headers.
CCMD no longer uses copystring function.
ability to dynamically register CCMDs.
removed the 'caller' parameter from the CCMD dispatcher. This can never be anything but players[consoleplayer].mo, so there is no need to pass it through the interface.
separated the button code from c_dispatch.
replaced Travis and AppVeyor with GitHub actions
split off the console's command line class into its own file.
CVAR cleanup, in particular decoupling from game internals, which now get handled via callbacks.

renamed fullscreen CVar internally to vid_fullscreen to make searching for it easier.
make DumpCPUInfo return a string instead of letting it print the info itself. Also consolidated I_Init, because both existing versions were identical.
major code refactoring to improve reusability of low level utility code
move SuperFastHash to its own set of files, instead of having this tied to the console.
replace swapvalues with std::swap globally.
added printf.h header to avoid including more dirty ones for the console printing functions.
cleaned up the includes in m_png.h, this file had far too many and far too broad dependencies.
moved the dictionary implementation into the 'scripting' folder where it really belongs.
copied some fixes for overlong config entries from Raze.
renamed basictypes.h to basics.h to keep the file name in line with Raze and make comparisons easier.

Added $OPTVAL_MBFSTRICT to menudef.txt, and added corresponding case 7 to the compatmode cvar in d_main.cpp
removed the obsolete Doomsday 1.8-style texture pack support. This poorly integrated into the texture system and wasn't compatible with modern texture packs anymore so its usefulness was questionable.

stop all sounds after exiting level regardless of intermission screen
fixed comparison with uninitialized data in MAPINFO parser
use GAMENAMELOWERCASE macro for music config defaults
added Romanian to the language selection menu.
