GZDoom 4.8.1

Mainly a bugfix release, but contains a major update of the Vulkan backend

- let the "abort" button on the network pane of the startup screen do a hard exit on Windows.
- Bugfix for software mode mirrors not working
- make sure ticdup is initialized.
- Add +ONLYVISIBLEINMIRRORS and +INVISIBLEINMIRRORS actor flags. The former makes the actor only visible in reflections, while the latter makes the actor not cast reflections in mirrors.

- allow taking screenshots in cutscenes.
- fixed JIT target function for GetTimeFrac.
- fixed: For cutscenes the alternative clean scaling factors need to be activated.
- fixed setup of ready state with Dehacked. This needs to emulate the hard coded chainsaw sound when weapon states get reassigned.
- Fix the discolored sky bug on Vulkan
- check point pushers/pullers by inheritance, not absiolute match
- Implement FVector ZScript for Actor Scale
- added FailSound property to PuzzleItem

- set `i_pauseinbackground` to match `!(i_soundinbackground)` for all configs before this commit.
- fixed division by zero with unvalidated ticdup values.
- reinstated con_scale.
- make sure the last notch on the start screen is rendered.
- fix relative include path when loading folders
- avoid storing texture pointers in longer lived data

GZDoom 4.8.0

Highlights
- added Raze-style HUD scaling. Not exposed in the menu yet, Set hud_oldscale to 0 and use shift with the screen resize keys to scale the status bar.
- handle the start/endoom screens with the ingame renderer. They are now present on all platforms and use the full screen size of the game.
- Many MBF21 fixes.
- 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.
- added Raze-style HUD scaling. Not exposed in the menu yet, Set hud_oldscale to 0 and use shift with the screen resize keys to scale the status bar.
- added a few more names to the reserved names for main folder detection.
- consider "fonts" and "models" reserved folder names.
- fixed undefined behavior with Dehacked's value parser.
- Rebuild nodes for 1024.wad MAP02 to fix invisible obstacle near the exit area
- fixed fast crushers going out of sync if something is being crushed by them.
- fixed: Vulkan descriptor sets must check the real translation, not just the translation ID.
- handle the start/endoom screens with the ingame renderer.
- Create a MainWindow class that manages the main win32 window of the application
- Added Actor::LightLevel. Setting it to any value > -1 will override the sector's light level.
- Implement virtual Actor.FallAndSink for scriptable falling and water physics
- Added Actor.WaterDepth to retrieve how submerged and actor is, in map units
- added cutscene data parser. This covers: game start, episode start, cluster start/end, level start/end.
- MASTERNOSEE flag (#1601) Makes it so that if an actor's master is invisible due to camera/mirror/portal shenanigans, then the actor will also be invisible. Name based off of an Unreal Engine flag that does the exact same thing.
- 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.
- Add WorldOffset field. Adjusts the thing's 3D position on render side. This allows for adjusting a thing's visual position without impacting their hitbox.
- fix bad MP start spot in 1024.wad, MAP05
- Enables shortcuts for option menus. Press a key to immediately jump to the next option menu entry which starts with this key. Hold Alt to jump backwards.
- DontLightOthers: Acts as the inverse of DontLightSelf, where it won't light actors that aren't the owner.
- DontLightMap: The light doesn't affect the map.
- Relative Includes for ZScript
- remove m_filter and simplify related code
- exclude keys from ‚artifact‘ cheats
- fixed MF_SHADOW handling for MBF21. This needs to alter the render style as well.
- fixed handling of automap sprites with negative scale.
- fix dynamic light setup. The level’s global flag is unreliable and cannot be used. The operation this was initially supposed to skip cannot be skipped anyway so the impact should be minor.
- Allow SendNetworkEvent during title level.
- add sv_ammofactor to change the skill adjustment for ammo
- extended the read buffer for the 'secret' CCMD.
- This is merely preparation - the actual loading is still in one uninterrupted piece.
- Fix that vk_debug doesn't output anything for newer versions of the vulkan sdk
- added JPEG YCCK decoding.
- Added MF8_SEEFRIENDLYMONSTERS. Non-friendly monsters with this flag on will be able to attack friendly monsters on sight.
- fixed mouse coordinate checks for Strife conversations. ypositions needs one entry per response, not one per line.
- fixed radius of BossBrain actor
- Added QF_3D flag for quakes. When used, the quake thinker will perform a 3D distance check instead of 2D.
- removed compat_soundcutoff from the menu. Handling for this was removed 14 years ago when ZDoom transitioned to FModEx 4.x
- add -compatmode for setting a compatibility mode on startup as a replacement for +compatmode not working as intended.
- activate Hungarian in the menu
- Fix off-by-one in Vulkan multisample sample count selection

- fixed setup of files to load on startup.
- fixed return type of MSTimeF script function.
- moved -rngseed init to D_InitGame
- pass ´hashfile´ to filesystem as parameter
- fix TArray::Append with rvalue parameter. This must clear the source array to obey move rules.

- added missing BLOCKF_ flags for ZScript.
- added ‚repeat‘ option to SetLineActivation ACS function
- made friendlyseeblocks writable.
- removed all remains of the corpsegibs flag and made vileghosts interactive. Ghosts are still off by default, but they will now be enabled when selecting the vanilla (strict) compatibility mode.

- let A_SpawnParticle respect the float bob offset
- separate message for disabling noclip2
- added a nullptr check for StatusBar when drawing „Paused“
- make menu scale adjustments for ultra-wide aspect ratios.
- treat PSP layer ID 0 as invalid. No PSprites with this ID may ever be created, as there is no means to find them again.
- fixed: The skill menu did not remember its last selection.

- added vertical bullet spread relative to ssg
- Fixed GUS Emulation with DMXGUS(C) lump conf.
- changed default value for midi_config to empty string since gus is not working with sf2 file
- fixed SetupDMXGUS not loading lump correctly, wrong use of CheckNumForFullName
- midi_config default to empty string, since lzdoom.sf2 doesn't seem supported (distorted sound)
- added absolute paths to FZipPatReader so we can add custom patches to resource files by using gus_patchdir and/or ULTRADIR variable (some custom maps has custom patches that can be added this way without putting them inside the resource file or in the same folder of the configuration file)
- set timidity_reverb_level min value to 0 in menudef.txt, set to 9 by mistake?
- Added the MF8_DONTFOLLOWPLAYERS flag, which allows friendly monsters to not follow their FriendPlayer when they have no target or goal left to head to.
- fixed Font struct export and removed the duplicate handler.
- fix detection for misplaced | when creating the small fallback font
- typo 'Yea' instead of 'Yes'

Mainly a bugfix release addressing the following issues:

• Fixed: SBar_DrawTextureRotated was missing the angle parameter
• Compat patch for misplaced items in Hexen MAP08.
• fixed some imprecisions in font luminosity calculation. This was still going through the palette which could result in off-by-one errors.

• fixed memory leak in DShape2DBufferInfo.
• allow "INDEXFON" as an alias for "INDEXFONT".
• fixed A_Punch having a short attack range (take 2).
• GLES: Fix texture MapBuffer and AllocateBuffer create client side memory.
• Fix "out of memory" errors when the vulkan backend is asked to create zero byte sized buffers
• resolved a VM abort upon morphing while the tome of power is active

• PreTravelled virtual for player and inventory.
• Allow customization of pause screen.
• ReadThisMenu / MenuDelegate overriding.

GZDoom g4.7.0

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.

GZDoom 4.6.1

• Fixed bug with BishopPuff moving in wrong direction

• a couple important widepix fixes

• fix for "Return to Phobos (return01.wad) has an ancient bug in map E1M2 where the switch to raise the exit bridge doesn't work in versions of Doom past patch 1.2."

• add missing break statement in level_compatibility.zs

• fix DaggerAlert using FindState incorrectly.

• Fixed wrong parameter type passed into TryMove here

• fixed: Actors did not set the position when spawning a dynamic light.

• Add 'AddDialogues' in MAPINFO to additively add Strife NPC dialogs without overwriting each other.

• let dynamic lights call UpdateLocation instead of just setting their position right after being spawned. This ensures that the position is correct and that everything gets set up properly.

• fixed parsing of MAPxx par times in BEX lumps

• Make sprite shadows ignore float bob

• fixed explosive damage radius for clericflame.

• fixed permission validation in OptionMenuItemCommand.DoCommand. This was missing the InMenu check like the other critical menu functions.

• added detection of macOS 12 Monterey

• prevent redundant string copying in Strife conversation parser

• Fixed impassable exit line in 007ltsd.wad E4M7

• fixed initialization of model frames

• fix missing border flat on heretic shareware

• fixed parsing of 2D vectors in OBJ model loader

• added TVector2<> constructor from float*

• fixed bad type in FxFontCast.

• fixed potential crash when sound sequence is destroyed. Level can be unset if sound sequence destruction happens after saved game loading failure

• report correct macOS version with older SDKs

• Add Windows 11 detection

• 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

GZDoom g4.5.0

• 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.
• major additions to the menu system - animated menu transitions, image slideshows and fixed size menus can now be created.
• the console now uses the border flat as default background instead of the titlepic.
• it is now possible to fully quit the fullscreen console and get back to the title loop.
• various enhancements and fixes for ZScript.
• Interpolate positions and angles in the automap for smoother appearance
• Added $PitchSet for SNDINFO.
• allow indirections in the string table by prefixing the language string with '$$' the remaining text is interpreted as another string label to resolve.
• optimization of the patch texture checker - do not read in the entire file if checking the initial header is sufficient for rejecting it. This can speed up loading of large mods quite significantly.
• MIDS-format MIDI support
• OPUS support, courtesy of an updated libsndfile.
• libADL/libOPN update

moved benchmark fps output to the custom part of it because it depends on game data.
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

block off the Substitute function by making it private to the 3 classes that really need it.
let TeleportSpecial universally map to Teleport when checking action special names.

removed the "no IWAD definitions found" error message because the condition it checks for is not an error.
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.

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.
moved the handling for paletted replacements into 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 correc...
