DD Mmm YY - 1.54

add: in_qwerty <0|1> (default: 1) forces the QWERTY layout for key bindings
  0 - uses your active regional layout (such as AZERTY, QWERTZ, etc.)
  1 - uses the QWERTY layout

add: FFmpeg piping support for compression of audio/video captures
  cl_ffmpeg <0|1> (default: 0) uses FFmpeg instead of writing raw .avi files
  cl_ffmpegCommand <string> are the FFmpeg command-line options for the output file
  cl_ffmpegExePath <string> (default: "ffmpeg") is the path of the FFmpeg executable to use
    note that the path cannot contain spaces on Windows
  cl_ffmpegOutPath <string> (default: "") is the video output directory
    leave empty to write to cpma/videos as with .avi files
  cl_ffmpegOutExt <string> (default: "mp4") is the output file extension
  cl_ffmpegLog <0|1> (default: 0) enables the creation of 1 log file per capture

add: togglegui and toggleguiinput to toggle (the mouse input of) the built-in GUI system

add: key binds starting with "keycatchgui" always take precedence over everything else
  they will work in the main menu, the demo player in protected mode, when the console is down, ...
  here's how you would bind keys to access the new built-in GUI:
  bind F1 "keycatchgui;togglegui"
  bind F2 "keycatchgui;toggleguiinput"

add: r_guiFont <0|1|2> (default: 0) sets the GUI's font
  0 - Proggy Clean (13px)
  1 - Sweet16 Mono (16px)
  2 - custom font file (see r_guiFontFile and r_guiFontHeight)
  note that the custom font can only get loaded at client start-up

add: r_guiFontFile <string> (default: "") is the file path to the custom .ttf font file

add: r_guiFontHeight <7 to 48> (default: 24) is the custom font's height

add: r_gpuPreference <0|1|2> (default: 0) sets the GPU selection preference
  0 - high performance (discrete graphics)
  1 - low power (integrated graphics)
  2 - none

add: r_gpuIndex <0 to GPU count> (default: 0) sets the specific GPU to use
  0 - default (falls back to r_gpuPreference)
  I - uses the GPU at index I from /gpulist

add: /gpulist lists available GPUs, the numbers can be used to set r_gpuIndex

add: r_sleepThreshold <2000 to 4000> (default: 2500) is the frame sleep time cushion, in microseconds
  it's a trade-off between frame time consistency and CPU usage
  set to 2000 if you have a struggling old/low-power CPU
  2500 should be enough to deal with delayed thread wake-ups
  use the frame graph to confirm that higher values help on your system

add: r_smaa <0 to 4> (default: 0) enables enhanced sub-pixel morphological anti-aliasing
  0 - no SMAA
  1 - low quality
  2 - medium quality
  3 - high quality
  4 - ultra quality

add: r_shadingRate <0 to 6> (default: 0) sets the variable-rate shading (VRS) mode
  0 - 1x1 (VRS off)
  1 - 2x1 (base mode)
  2 - 1x2 (base mode)
  3 - 2x2 (base mode)
  4 - 4x2 (extended mode)
  5 - 2x4 (extended mode)
  6 - 4x4 (extended mode)
  the numbers are the horizontal and vertical subsampling factors
  1x1 is forced for the sky, nopicmipped sprites (e.g. simple items)
  and nopicmipped alpha tested surfaces (e.g. grates)
  if extended modes are not supported, 2x2 is used instead
  prefer horizontal subsampling as many maps have textures with thin horizontal lines
  which become an aliased mess when vertically subsampled

add: r_normalSmoothing <0|1> (default: 1) enables smooth vertex normal generation

add: r_normalAreaWeight <0|1> (default: 1) enables area weighting for vertex normal generation

add: Cinematic Rendering Pipeline CVars
  depth of field:
    crp_dof <0|1|2> (default: 1) selects the depth of field mode
      0 - disabled
      1 - scatter-as-gather
      2 - accumulation
    crp_dof_overlay <0|1|2> (default: 0) draws a debug overlay mode
      0 - disabled
      1 - colorized blur
      2 - focus plane
    crp_dof_blades <0 to 16> (default: 6) is the aperture's blade count
      set to less than 3 for a disk shape
    crp_dof_angle <0 to 360> (default: 20) is the aperture's angle, in degrees
  scatter-as-gather depth of field (fast, doesn't handle transparency properly):

    crp_gatherDof_focusFarDist <1 to 2048> (default: 512) is the far-field's focus distance
    crp_gatherDof_focusFarRange <1 to 2048> (default: 384) is the far-field's focus range
    crp_gatherDof_brightness <0 to 8> (default: 2) is the blur brightness' weight
  accumulation depth of field (extremely slow, looks perfect with enough samples):
    crp_accumDof_focusDist <2 to 2048> (default: 256) is the focus distance
    crp_accumDof_radius <0.001 to 20> (default: 0.1) is the aperture radius in world units
    crp_accumDof_samples <1 to 12> (default: 2) is per-axis sampling density
      density N means (2N + 1)^2 scene renders in total, so be careful or you'll trigger TDR
    crp_accumDof_preview <0|1|2> (default: 0) selects the real-time preview mode
      0 - disabled
      1 - 1/4 pixel count, 9 samples total
      2 - 1/16 pixel count, 25 samples total
  motion blur:
    crp_mblur <0 to 3> (default: 0) sets the motion blur mode
      0 - disabled
      1 - camera blur only
      2 - object blur only
      3 - camera and object blur
    crp_mblur_exposure <0.0 to 1.0> (default: 0.5) is the exposure time in percentage of frame time
  miscellaneous:
    crp_sunlight <0|1> enables sunlight on non-lightmapped surfaces
    crp_volLight <0|1> enables volumetric lighting
      fog volumes are lit by ambient light, dynamic lights and sunlight
    crp_drawNormals <0|1> (default: 0) draws vertex normals as colorized wireframe lines
    crp_updateRTAS <0|1> (default: 1) enables raytracing acceleration structure builds every frame

add: Cinematic Rendering Pipeline commands
  cin_freezeFrame freezes the rendered frame (minus ImGUI and tone map) and G-Buffer for inspection
  cin_freezeFrameMB freezes the rendered frame (minus ImGUI, tone map and motion blur)

fix: allocating enough memory for 4K screenshots and video captures

fix: the new demo player now drops zombie snapshots and snapshots from before a server time rewind
  these problematic snapshots happen right before and after gamestate changes

chg: dropped 32-bit support

chg: dropped Linux/FreeBSD client

chg: Windows support is limited to 10 and 11

chg: reworked renderer with 2 new rendering pipelines
  - removed all the Direct3D 11 and OpenGL code, now using Direct3D 12
  - much improved input latency when V-Sync is enabled
  - improved frame-time consistency ("frame pacing")
  - MSAA and alpha-to-coverage have been removed
  - Gameplay Rendering Pipeline (GRP)
    - improved performance and better worst case input latency
    - added SMAA for anti-aliasing (gamma-corrected and not applied to UI for best results)
    - added VRS (Variable Rate Shading) support
    - overhauled fog handling (faster, simpler, decoupled from surfaces)
  - Cinematic Rendering Pipeline (CRP)
    - order-independent transparency
    - depth of field (scatter-as-gather or accumulation)
    - shadowed point lights and sunlight
    - volumetric lighting: fog and NanoVDB animations lit by ambient light, point lights and sunlight
    - all corresponding CVars have the "crp_" prefix
    - the CRP doesn't currently support software video scaling: r_mode 1 will behave like r_mode 0

chg: removed cl_drawMouseLag, r_backend, r_frameSleep, r_gpuMipGen, r_alphaToCoverage, r_alphaToCoverageMipBoost
  removed r_d3d11_syncOffsets, r_d3d11_presentMode, r_gl3_geoStream, r_ignoreGLErrors, r_finish, r_khr_debug
  removed r_verbose, r_customaspect, r_speeds, r_msaa, r_showsky, r_showtris

  replaced r_textureMode with r_lego <0|1> (default: 0) to enable nearest-neighbor texture filtering
  replaced r_shownormals with crp_debugNormals <0|1> (default: 0) to draw vertex normals


30 Oct 23 - 1.53

add: /registerdemos   adds Windows file associations for demo files (.dm_68 .dm_67 .dm_66)
  /unregisterdemos removes Windows file associations for demo files
  on Windows, /demo can now play demo files that have an absolute path (e.g. /demo C:\test.dm_68)

add: r_teleporterFlash <0|1> (default: 1) draws bright colors when being teleported (use 0 for black)

add: s_khz <22|44> (default: 22) is the sound mixing sampling frequency: 22.05 kHz or 44.1 kHz

add: /writeconfig now has a "-f" option to force writing all CVars (whether archived or not)

add: /imageinfo <imagepath> prints where the image was loaded from and shaders that reference it

add: /shadermixeduse prints all images referenced in shaders with conflicting global directives

add: cl_demoPlayer <0|1> (default: 1) selects the demo playback system to use
  cl_demoPlayer 0 = always uses the original demo player
  cl_demoPlayer 1 = uses the new demo player with time rewind support when the mod supports it

add: cl_escapeAbortsDemo <0|1> (default: 1) decides whether the escape key can abort demo playback
  reminder: you can always use /disconnect to stop demo playback

add: r_depthClamp <0|1> (default: 0) disables vertex clipping against the near and far clip planes
  enabling this feature will raise the maximum allowed FoV value of CPMA 1.53
  it turns the view frustum into a pyramid and prevents any vertex between the near clip plane
  and the camera's position from getting clipped (but will still clip anything behind the camera),
  which prevents solid objects from being seen through when too close to the camera
  because depth values are clamped, improper depth ordering can potentially occur

add: /shaderinfo <shadername> [code] prints where the shader was loaded from and optionally the code

add: console mark mode (selection mode) can be toggled with Ctrl-M
  use arrow keys, home/end or page up/down to move the cursor or extend the area when pressing shift
  Ctrl-C/enter copies the selected text to the clipboard without color codes and exits mark mode

add: /searchconsole begins a new console search
  press ctrl-F when the console is down to bring up the command
  press (shift-)F3 to find the next match going up or down
  just like in cmdlist/cvarlist/etc, * will match any amount of characters

add: r_ignoreShaderSortKey <0|1> (default: 0) ignores the shader sort key of transparent surfaces
  instead, it sorts by depth and original registration order only
  this is a work-around for broken maps like bones_fkd_b4 (grates drawn in front of simple items)

add: r_mapGreyscale <0.0 to 1.0> (default: 0) controls the map's desaturation level
  r_mapGreyscale 0 = full color (nothing done)
  r_mapGreyscale 1 = completely monochrome

add: r_mapGreyscaleCTF <0.0 to 1.0> (default: 0) controls the CTF map surfaces' desaturation level
  r_mapGreyscaleCTF 0 = full color (nothing done)
  r_mapGreyscaleCTF 1 = completely monochrome
  it applies to the red/blue color-coded surfaces of popular CTF/NTF maps

add: net_proxy <ip> (default: "") is the proxy server to use when establishing client connections

add: /waitms <milliseconds> to delay command executions by the specified number of milliseconds

add: r_alphaToCoverageMipBoost <0.0 to 0.5> (default: 0.125) boosts the alpha value of higher mip levels
  with A2C enabled, it prevents alpha-tested surfaces from fading (too much) in the distance

chg: with hybrid core CPUs (e.g. Intel gen 12+) on Windows, the main thread will only run on the P-cores

chg: the client can now read .wav files from the local file system when connected to a pure server
  this allows e.g. cg_fragSound to load sounds from the local file system instead of .pk3 files

chg: CVar sets will use all arguments instead of only the first one
  example: pressing n with `bind n "name x y z"` will rename to "x y z" instead of "x"

chg: invertedpenguin's RA blood pool has a new look to help better see the RA against its background

chg: forcing the nopicmip flag on 2 new texture folders: "textures/npmenv" and "textures/npmpads"

chg: r_vertexLight 1 no longer collapses shaders but replaces lightmaps with vertex colors
  for transparent shaders, lightmaps are still used because vertex colors are broken on some maps

chg: bots can no longer get timed out (it happened sv_timeout seconds after bot_pause was enabled)

chg: r_gpuMipGen 0 now respects r_mipGenFilter but not r_mipGenGamma (gamma 2 is used)
  the new code will slow down map loads in general but produces higher quality results
  r_mipGenFilter BL is a special case without gamma correction that's much faster than before

chg: image load/save errors now print warnings instead of triggering drop errors

chg: the maximum texture resolution of 2048 is now enforced in all image loads

chg: updated icon courtesy of deft

chg: r_showtris/r_shownormals <bitmask> (default: 0) draws wireframe triangles/vertex normals
   1 - enables the feature
   2 - only draws for visible triangles
   4 - draws for backfacing triangles
   8 - uses the original vertex color
  16 - uses the original vertex alpha as vertex color

chg: r_lightmap 1 now handles most alpha-tested surfaces

chg: com_soundMegs now defaults to 16

chg: the camera's near clip plane distance is now 1 instead of 4

chg: with r_backend GL3, depth fade with MSAA now requires GLSL 4.00 at a minimum
  depth access is now correctly multi-sampled (less aliasing) and performance has improved as well

chg: with r_backend GL3, alpha to coverage now requires GLSL 4.00 at a minimum

fix: the renderer could crash on some maps without lightmaps (e.g. b0_beta5)

fix: with r_backend GL2, the extra clip plane for mirror/portal surfaces was not being used
  this quick fix is likely to fail for some drivers and vendors due to its use of deprecated features
  based on a few tests: OK on NVIDIA and Intel, not working on AMD

fix: long demo file names would cause video recording to output files with no extension or outright fail

fix: invalid skybox texture mip-mapping and filtering settings (e.g. cpm25 skybox seams)

fix: in render batches with multiple shaders where the second or later surface had a shader using
  "rgbGen lightingDiffuse", the colors would be wrong and crashes could occur

fix: the reported MSAA sample counts for the GL2 and GL3 back-ends could be wrong

fix: registration of a read-only CVar would keep the existing value

fix: the Direct3D projection transform didn't perfectly match the OpenGL version

fix: /video was writing incorrect audio stream lengths to the .avi file headers

fix: /systeminfo /serverinfo /clientinfo /dumpuser would crash when tokens were too long

fix: with r_lightmap 1 and r_dynamiclight 1, lighting transparent surfaces could crash

fix: delayed shader loads could lead to incorrect rendering and crashes (mostly with dynamic lights)

fix: the nextdemo variable wasn't used to start the playback of a new demo when:
  - a drop error happened during demo playback
  - the engine failed to open the current demo file

fix: the Linux/FreeBSD client could crash during start-up

fix: with r_backend D3D11, the alpha channel's blend factors now match the original Q3 behavior
  this affects shaders that use the following blendFunc modes: GL_DST_ALPHA, GL_ONE_MINUS_DST_ALPHA
  examples: jumppads on cpm3a and cpmctf3, jumppad trims on q3wcp14, shiny walls on q3wcp9

fix: batched surfaces with "tcMod turb" would generate incorrect texture coordinates

fix: throwing a fatal error when com_soundMegs is too low to load a map instead of freezing

fix: /video produced .avi files that started with silence when they were not first in the sequence

fix: with r_backend D3D11, some device reset scenarios caused fatal errors instead of video restarts

fix: CVar slots that have been freed (e.g. through unset/cvar_trim/cvar_reset) can now be re-used

fix: with alpha to coverage enabled, high r_picmip values should no longer cause
  alpha-tested surfaces to become transparent in the distance (e.g. q3wcp14 corridor floors)

fix: with r_backend GL3, caching of shader uniforms could break with fog-only shaders

fix: with r_backend D3D11, partial clears incorrectly affected entire render targets
  example: black views in CPMA multi-view with r_fastsky 1


01 Jun 20 - 1.52

add: FreeBSD x64 support

add: r_backend <GL2|GL3|D3D11> (default: D3D11 on Windows, GL3 otherwise) selects the rendering back-end
  GL2   - OpenGL 2.0 minimum, OpenGL 3+ features used for r_msaa
  GL3   - OpenGL 3.2 minimum, OpenGL 4+ features used for faster geometry upload, compute shaders, etc
  D3D11 - Direct3D 11 hardware feature level 10.1 minimum, feature level 11.0 for compute shaders

               r_backend | GL2    | GL3    | D3D11
  feature         avail. |        |        |
  -----------------------|--------|--------|-------------------
  MSAA                   | GL 3.0 | always | always
  MSAA centroid sampling | never  | always | always
  depth fade             | never  | always | always
  alpha to coverage AA   | never  | always | always
  dithering              | never  | always | always
  GPU mip-map generation | never  | GL 4.3 | feature level 11.0

add: r_depthFade <0|1> (default: 1) enables depth fade rendering
  this helps explosions, smoke, blood, etc. not having "sharp edges" when intersecting geometry

add: r_alphaToCoverage <0|1> (default: 1) enables alpha to coverage anti-aliasing
  A2C AA can only work if MSAA is enabled (i.e. r_msaa > 1)
  it is used to super-sample all fragments of alpha-tested surfaces

add: r_dither <0|1> (default: 0) reduces color banding artefacts by adding noise

add: r_ditherStrength <0.125 to 8.0> (default: 1.0) controls the amount of noise added by dithering

add: r_gpuMipGen <0|1> (default: 1) enables GPU-side mip-map generation
  this helps improve map load time (less to upload) and image quality (see r_mipGenGamma, r_mipGenFilter)

add: r_mipGenGamma <1.0 to 3.0> (default: 1.8) specifies the gamma space in which the textures are stored
  r_gpuMipGen 1 is required
  it should be closer to 2.4 but defaults lower to not break the looks of some things (e.g. cpm3a tele)
  while 1.0 will preserve the original engine's look, higher values will preserve contrast better

add: r_mipGenFilter <filter> (default: "L4") specifies which filter window is used to generate mips
  r_gpuMipGen 1 is required
  the numbers specify the "radius" of the window filters
  r_mipGenFilter L4  = Lanczos
  r_mipGenFilter L3  = Lanczos
  r_mipGenFilter BL  = Bi-linear
  r_mipGenFilter MN2 = Mitchell-Netravali (B = 1/3, C = 1/3)
  r_mipGenFilter BH4 = 3-term Blackman-Harris
  r_mipGenFilter BH3 = 3-term Blackman-Harris
  r_mipGenFilter BH2 = 3-term Blackman-Harris
  r_mipGenFilter T2  = Tent (1/3 2/3) -> same as the CPU version (r_gpuMipGen 0)

add: r_frameSleep <0|1|2> (default: 2) selects the frame capping mode
  r_frameSleep 0 = forced OFF (when V-Sync is enabled)
  r_frameSleep 1 = forced ON  (when V-Sync is disabled)
  r_frameSleep 2 = automatic  (detects V-Sync status)
  this only applies to OpenGL rendering back-ends
  for Direct3D 11, the behavior is always equivalent to "automatic"
  the new default mode fixes the V-Sync stutter from previous releases

add: r_gl3_geoStream <0 to 4> (default: 0) sets the geometry upload strategy
  r_gl3_geoStream 0 = decide automatically
  r_gl3_geoStream 1 = BufferSubData
  r_gl3_geoStream 2 = Map Unsychronized
  r_gl3_geoStream 3 = Map Persistent when possible, else automatic
  r_gl3_geoStream 4 = AMD pinned memory when available, else automatic
  this only applies to the GL3 rendering back-end

add: r_d3d11_syncOffsets <0|1|2> (default: 2) synchronizes vertex buffer offsets
  r_d3d11_syncOffsets 0 = split  buffer offsets (more data transferred)
  r_d3d11_syncOffsets 1 = sync'd buffer offsets (more API calls)
  r_d3d11_syncOffsets 2 = decide automatically
  this only applies to the D3D11 rendering back-end

add: r_d3d11_presentMode <0|1> (default: 0) sets the Direct3D presentation mode
  r_d3d11_presentMode 0 = blit + discard
  r_d3d11_presentMode 1 = flip + discard when available, else blit + discard
  about the 'flip + discard' presentation mode:
  - Windows 10 is required and tearing must be supported
  - it should help performance by sharing buffer data (less copying)
  - it allows for V-Sync to be disabled with variable refresh rate displays
  - performance issues were observed on some machines, so it's off by default

add: r_khr_debug <0|1|2> (default: 2) decides whether to create an OpenGL debug context
  r_khr_debug 0 = forced OFF
  r_khr_debug 1 = forced ON
  r_khr_debug 2 = only in debug builds

add: r_rtColorFormat <0|1|2> (default: 0) selects the color format for render targets
  r_rtColorFormat 0 = R8G8B8A8
  r_rtColorFormat 1 = R10G10B10A2
  r_rtColorFormat 2 = R16G16B16A16
  higher color bit depths help reduce color banding

add: r_lightmapGreyscale <0.0 to 1.0> (default: 0) controls the level of color desaturation in the lightmap
  r_lightmapGreyscale 0 = full color (nothing done)
  r_lightmapGreyscale 1 = completely monochrome

add: r_transpSort <0|1> (default: 0) selects the transparency sorting mode
  r_transpSort 0 = sort dynamic transparent surfaces
  r_transpSort 1 = sort all transparent surfaces
  the drawback of r_transpSort 1 is that gameplay legibility might suffer and results might look
  quite inconsistent based on the view angles and surface dimensions
  example: dropped items in the cpm18r acid with cg_simpleItems 1

add: global shader directive q3map_cnq3_depthFade <scale> <bias> enables depth fade rendering
  scale is the depth range over which to fade the currently rendered surface
  bias  is a value added to the currently rendered surface's depth, positive goes towards the camera
  whether this is enabled is decided by r_depthFade (must be 1) and r_backend (can't be GL2)
  depth writes must be disabled in all stages (no shader stage can use the depthWrite directive)
  the blend mode (blendFunc) must be the same for all stages and must be one of:
    (one, one) (src_alpha, one) (one_minus_src_alpha, one) (dst_color, zero) (zero, src_color)
    (src_alpha, one_minus_src_alpha) (one, one_minus_src_alpha)

add: r_mapBrightness now works on q3map2's external lightmap atlas images

add: the renderer can now batch surfaces with different (but sufficiently similar) shaders
  this new optimization works with the output of "Frozen Sand Particle Studio"

add: /modellist /skinlist /imagelist /shaderlist can now filter results with pattern matching

chg: improved the map download initiation logic and updated the CNQ3 map server addresses

chg: increased the small zone allocator's size from 512 KB to 4 MB (1 MB in the dedicated executable)

chg: dynamic lights now use a different fall-off curve to create softer edges

chg: reverted an old change to the Escape key handling for cgame
  this fixes demo playback behavior in CPMA, which enables custom binds after pressing Escape once

chg: searching for valid sample counts for MSAA in GL2 and GL3 instead of failing right away

chg: switched away from stb_image for .tga file loading and now using an updated version of the old code
  this lowers the chances of a fatal error from the zone memory allocator when reading large images

chg: SSE2 instruction set support is now required

chg: removed FreeType 2 and the unused R_REGISTERFONT syscalls that were using it

chg: removed light flares and all related cvars (r_flare*)

chg: r_textureMode <filter> (default: "best") is now latched and only supports 2 modes:
  r_textureMode GL_NEAREST    = LEGO(R) mode - nearest-neighbor filtering for a subset of surfaces
  r_textureMode anything else = normal  mode - the engine picks the most appropriate filters

chg: removed the following CVars: r_measureOverdraw, r_nobind, r_showImages

chg: r_speeds is no longer cheat-protected
  it now also reports more precise timings, V-Sync status, GPU time and the selected back-end

chg: using the roundss SSE4.1 instruction for inlining floor and ceil syscalls when possible

chg: improved face and grid processing performance with SSE2

chg: r_lightmap is now latched again
  the implementation is now more correct and will apply to all surfaces referencing a lightmap
  it now also supports surfaces referencing q3map2's "external lightmap" atlas images

chg: r_fullbright is now latched again
  it now also supports surfaces referencing q3map2's "external lightmap" atlas images
  r_mapBrightness is now used by r_fullbright for lightmapped surfaces when r_vertexLight is 0

chg: negative r_swapInterval values will request adaptive V-Sync when using an OpenGL back-end

fix: the engine could crash due to render command list overflows

fix: made more keys bindable on Linux/FreeBSD and /bind now accepts uppercase hex digits

fix: removing CVars through unset/cvar_trim/cvar_restart could leave data in an invalid state

fix: r_detailTextures 0 would mess up shaders where "detail" was used in a stage that isn't the last one

fix: dynamic lights could incorrectly stop applying to moving entities (e.g. cpm25 elevator)

fix: crash due to lack of memory for the sound system

fix: incorrect shader state when loading a map with no lighting

fix: fog-only non-sky shaders were incorrectly handled as sky shaders, which broke fog on many maps

fix: r_monitor on Linux/FreeBSD is now 0-based and the value doesn't change incorrectly on its own anymore

fix: when a latched cvar's value is set to its default, the cvar is no longer marked as changed

fix: broken face normals get fixed up on map load, which helps with dynamic lights (e.g. industrial)

fix: classes of transparent surfaces (sprites, beams, etc) now get drawn in the right order

fix: dynamic lights can now affect transparent surfaces and double-sided surfaces on both sides

fix: dynamic lights no longer "reveal" the diffuse texture when r_lightmap is 1

fix: incorrect image flags for various things (clamp mode, mip generation, anisotropic filtering, ...)


31 Mar 19 - 1.51

add: now showing the cvar's current and latched values in the help panel

add: new console and chat keyboard shortcuts
   Ctrl-left/right arrow | move caret to previous/next word
  Shift-left/right arrow | move caret to previous/next argument

add: new console keyboard shortcuts

  if the cvar's current value is in the sequence and not in the last spot, the next one is used
  otherwise, the first value in the sequence is used

chg: r_lodCurveError <250.0 to 10000.0> (default: 2000) is now archived and no longer cheat-protected

chg: multi-monitor support improvements
  add: /monitorlist will print all detected monitors and the indices to use with r_monitor
  chg: the monitor list now gets updated during video restarts and calls to /monitorlist
  chg: Linux   | r_monitor is a 0-based index and monitors are sorted top-to-bottom, left-to-right
  fix: Windows | the Windows + shift + left/right arrow key shortcuts should be usable now

chg: bundling lightmap tiles into texture atlases for improved rendering performance

chg: faster map loads by limiting the rendering back-end's frame-rate

chg: on Windows, the upper limit of open stdio file handles was raised from 512 to 2048

fix: no longer feeding cs commands that came from a previous gamestate to cgame
	example in CPMA: "/map cpm22" -> "/cv map cpm25" -> elevator sound was broken

fix: on Windows, could sometimes click outside the engine's window in raw mouse input mode

fix: when r_msaa was in the range [2, 16], the requested sample count was always 4

fix: /video and /stopvideo fixes
  chg: /video can only be used during demo playback
  fix: broken audio in the output files
  fix: properly named file sequences
  fix: using a better supported video codec (FourCC 0x00000000) for raw BGR output
  fix: broken raw video output when r_width wasn't a multiple of 4

chg: the "nextdemo" cvar is now also used when playback stops before reaching the demo's end

chg: mouse motion is no longer forwarded to the mod when the console is down

chg: with 2+ monitors, having the console down will always disable input grabbing

chg: on Windows, a fatal error will move the early console window to the foreground

chg: com_hunkMegs doesn't have a maximum value anymore
  a value too high would reset it and the engine might fail to load with the default value

fix: broken pk3 files could cause crashes (entry names too long) and mess up the FS

fix: using /demo when running a listen server would load the map and then abort playback

fix: no longer making local copies of all the system info cvars of the current server
  this avoids undesired local changes to cvars such as sv_pure

fix: now updating the FS (connected to pure server, pak references) on client disconnects

fix: the condump command was truncating its file path argument to 64 characters

fix: "timedemo" playback runs at full speed again

fix: on Windows, when unfocused, the client would always sleep 5+ ms regardless of com_maxFPS

fix: conditional FS restarts will always re-order the pak list when connected to a pure server

fix: lifted the directory scanning restriction that affected pure listen servers

fix: getting stuck on "Awaiting snapshot..." when the server shuts down during client connection

fix: demo playback would crash when delta entities/players had an invalid field count

fix: strcpy calls with overlapping buffers (undefined behavior), which were responsible for the
  "chars.h not found" / "couldn't load any skills" issue preventing bots from being added

fix: on Linux, the 'Z' and '9' keys could not be bound

fix: cl_allowDownload 1 failing on "connect" (error 10047 on Windows)

fix: cl_allowDownload 1 was using the current directory instead of fs_basepath

fix: jitter due to snapshots piling up with the same server timestamp for loopback and LAN clients

fix: the Windows crash handler would incorrectly consider certain exceptions as fatal

  searchhelp <pattern>  to list all cvars and commands whose help or name matches the pattern

add: new CNQ3 download system that uses checksums to get the right pak files
  the CNQ3 download system will use the WorldSpawn map server for inexact queries
  (when loading demos or using /dlmap) when the CNQ3 map server doesn't have the file

  system | speed | cases               | source(s)     | file availability | server requirements
  -------|-------|---------------------|---------------|-------------------|--------------------
  CNQ3   | fast  | pure servers, demos | map server(s) | not guaranteed    | none
  id     | slow  | pure servers only   | the Q3 server | guaranteed        | sv_allowDownload 1

add: new commands for manually initiating and canceling fast downloads:

add: con_scaleMode <0|1|2> (default: 0) specifies the console text scaling mode
  con_scaleMode 0 = text size scales with con_scale but not the resolution
  con_scaleMode 1 = text size scales with con_scale and the resolution
  con_scaleMode 2 = text size is always 8x12

add: command history saving with con_history (default: 1)

add: r_monitor <0 to monitor count> (default: 0) to select the monitor to display the game on

chg: reduced CPU usage in the client

chg: console/messagemode input buffers now display the "^" character of color codes

chg: r_brightness    <0.25 to 32.0> (default: 2) replaces r_overBrightBits
     r_mapBrightness <0.25 to 32.0> (default: 2) replaces r_mapOverBrightBits
  the new cvars use floating-point values (more control) and a linear scale (more intuitive)
  to convert the old engine values to the new values:
  r_brightness    = pow(2, r_overBrightBits)
  r_mapBrightness = pow(2, max(r_mapOverBrightBits - r_overBrightBits, 0))

chg: r_mode <0|1|2> (default: 0) selects the video mode
  r_mode 0 = no screen mode change, desktop resolution
  r_mode 1 = no screen mode change, custom resolution, custom upscale mode
  r_mode 2 = screen mode change, custom resolution (for the CRT users)
  Custom resolution means using r_width and r_height.
  Custom upscale mode means using r_blitMode.

chg: cl_allowDownload <-1|0|1> (default: 1) can be used to select the download system
  cl_allowDownload -1 = id's original download system

chg: using stb_image to load png and tga images

chg: con_scale <0.25 to 10.0> (default: 1.2) specifies the console text scaling factor and nothing else

chg: replaced monitor gamma by a post-process gamma shader and removed r_ignorehwgamma

chg: removed stereo rendering

chg: anti-aliasing sample count is set with r_msaa on all platforms (on Windows, it was r_ext_multisample)

chg: file system start-up will now verify the presence and integrity of baseq3/pak0-8.pk3 instead of only pak0

chg: replaced id's Huffman codec code with something both simpler and much faster

chg: tweaked console scrolling speeds, fixed backtip insertion on Windows

chg: improved level load times

chg: sound fall-off is linear instead of using a power function

chg: switch from libjpeg 6 to libjpeg-turbo

chg: removed the byzantine r_mode usage added in 1.47

fix: console/messagemode input buffers would ignore the last off-screen color modifier when scrolled

fix: console/messagemode input buffers would sometimes display the cursor at the wrong position

fix: taking screenshots with a render width (r_width) that wasn't a multiple of 4
  would either crash or produce bad screenshots

fix: false positives of the "SCR_UpdateScreen: recursively called" fatal error
  repro: connect, get kicked, connect, get kicked

fix: crash when the number of shader stages was wrong (would happen with the "brandon" player model)

fix: the release of a key bound to "+vstr a b" would execute "b" even though the key press didn't execute "a"

fix: /bind was treating single-character key names in a case sensitive manner

fix: r_fullbright is no longer latched and actually does its job

fix: r_lightmap is now archived and actually does its job

fix: commands registered by cgame no longer auto-complete after the cgame qvm has shut down

fix: broken rendering when the 2nd stage of a collapsed shader stage pair had non-white colors

fix: shader stages using "wave" were not animated when the server time was too large

fix: the pukka3tourney2 slime wasn't green with r_vertexLight 1

fix: the ct3ctf1 grate near quad was getting picmipped when it wasn't supposed to be

fix: improved the player name look-up behavior for these commands: kick, banUser, dumpuser
  if 2 players had the same name, it would just pick the first one (lowest client number)

fix: multi-view mouse input sensitivity is now the same as in the UI for compatible mods like CPMA 1.50

fix: fixed the start-up console window staying visible when starting in full-screen


Windows:

add: in_minimize registers a hotkey to minimize/restore the client
  key names must be separated by white space and there can be at most 2 modifier keys

chg: removed DirectInput mouse input mode

chg: updated mouse input for better grab (de-)activation and fixed window dragging not working

chg: reduced raw mouse input latency and added cl_drawMouseLag

fix: disabled DPI scaling on the client

fix: the crash handler will reset the system timer resolution

fix: if requesting a resolution too high for the display, the image would be offset vertically

fix: in raw mouse input mode, keeping any button pressed while focusing the window would keep
  the cursor visible even after releasing all buttons


Linux:

add: m_relative <0|1> (default: 1) enables SDL's relative mouse mode
  you might want to set it to 0 if you have a messed up input driver

add: in_focusDelay <0 to 100> (default: 5) is the time in ms keypresses are ignored after the window gets the focus

add: minimize command to minimize the client's window

add: automatic dedicated server process restarts for crashes and timed reboots (sv_minRebootDelayMins)
  this means 2 CNQ3 processes run per server: a parent (fixed pid) and a child (new pid after each restart)
  this behavior can be disabled by passing "nohardreboot" as a command-line argument
  the new command sv_restartProcess can be used to shut down the child process and start a new one

chg: the client requires SDL 2 - the following things are handled by it:
  window, GL context, video modes, audio, kb and mouse input, monitor list, clipboard

chg: tty input behavior matches in-game behavior when cgame is running and fixed the truncated tty input

fix: color codes (e.g. "^1") don't get printed to the terminal anymore

fix: tty handling of the leading "]" character

fix: dedicated servers no longer insert a leading backslash when running auto-completion

fix: the crash handler will reset tty input mode correctly


17 Sep 11 - 1.47

add: backported another bunch of dlight stuff from the pmx branch
  adds support for bmodel entities (doors, plats, etc)

fix: in_mouse -1 kept relocating the system cursor even if not focused

fix: implement the sound change from 1.45 *correctly*  :P

fix: default build does not create option r_smp. To assemble the build 
      with the option r_smp need to use preprocessor USE_R_SMP

fix: small fixes to CVA rendering code

fix: fix opStack and rename targets for unix

fix: GTV/spectator can't change POV after map changed

fix: render shader time overflow (fix splashdamage bug).

fix: mouse event queue


24 Nov 09 - 1.46

add: m_limit (default: 0 = off), the maximum post-accel speed to use

chg: sensitivity renamed to m_speed

chg: rewrote pretty much all the mouse code

chg: removed the DI code in favor of "raw" mouse input
  this means only mouse1-mouse5 are supported on windows, sigh MS...

chg: updated freetype from 2.3.5 to 2.3.11


05 Nov 09 - 1.45
note: this release REQUIRES arb shader support
  if your card doesn't have it, use an older version

add: hw gamma should work on Vista

add: r_measureoverdraw is actually useful

add: r_speeds is far more useful now

chg: sound attenuation is biased
  i.e. distant sounds are much louder than in 1.43
  since it's still more correctly spatialised than pre-1.43, this is
  the best compromise i can come up with

chg: r_fullbright works in vertexlight mode (only)
  instead of lightmap only, where it just wasted bandwidth and vram

chg: r_customwidth, r_customheight renamed to r_width, r_height

chg: hardcoded r_mode garbage and modelist removed:
  r_mode 0 (default) = current desktop resolution, depth, hz, etc
  r_mode 1 = custom resolution etc
  note: r_mode 1 WILL NOT tolerate invalid r_displayRefresh values any more

chg: require opengl 1.4 or higher
  removed r_allowExtensions, r_primitives, r_ext_compiled_vertex_array,
  r_ext_multitexture, r_ext_texture_env_add

chg: removed a bunch of useless/obsolete cvars:
  r_logfile, r_showcluster, r_facePlaneCull, r_ignoreFastPath, r_drawSun,
  r_simpleMipMaps, r_offsetFactor, r_offsetUnits

chg: don't tablist cheatvar noise if cheats are off

chg: removed the last bits of legacy altivec cruft

chg: rewrote pretty much all the dlight stuff
  not only does it actually work reliably now
  but it's also massively improved in terms of quality

fix: ignorehwgamma 1 would fail to apply sw gamma to some images

fix: roqs failed to apply sw gamma

fix: sv_floodprotect could block all commands indefinitely


12 Aug 09 - 1.44 (server only)

fix: unbannable player exploit (stanway/auriemma)


08 Aug 08 - 1.43

fixed sfx0 using a real sound and thus "hiding" it

corrected sv_pure back to CVAR_ROM

added the correct "fastsky!=0 == disable portals" test, ffs me  :P

removed long-obsoleted r_lastValidRenderer

removed long-obsoleted r_ext_gamma_control

removed pointless cl_forceavidemo

removed r_rail* and marked the never-used RT_BEAM etc as such

removed RAVENMD4 completely

r_fullbright is not a cheat var

fixed a bug with CVAR_CHEAT

fixed another bug in \video (hopefully)

fixed distance culling on dlit patch seams

changed r_ext_max_anisotropy default to 16

added con_scale for console font scaling
0 = Q3 style, always 8x12 pixels regardless of screen rez
1 = Q4 style, scales with screen rez
!0 = scale with screen rez and a custom multiplier

straightened out the con cvar mess:
cl_noprint -> con_noprint
scr_conspeed -> con_speed and correctly CVAR_ARCHIVE
con_notifytime correctly CVAR_ARCHIVE
removed cl_conXOffset since it basically doesn't work

sleep correctly if an unfocused client (win32-only)
don't sleep INcorrectly if a dedicated server (win32-only)

fixed a (huge) memory leak in the vm

fixed sv_pure 1 problems on listen servers

another overhaul of the sound code:

spatialisation is now correct, which has two huge impacts:
  you can "place" sounds MUCH more accurately than before,
  but as a result, distant sounds are MUCH quieter

removed s_doppler, it's almost right but it just sounds like shit

most of the s_mixprestep hackery has been removed, and you can
probably set it to 0 if your sound drivers work properly

OAL support has been dropped completely and indefinitely
  it's crap and i'm tired of it poisoning the codebase


Mar 08 - 1.42

bots are no longer kicked by devmap

legacy cack like joystick/midi support only pollutes configs if enabled

fixed a memory leak in the sound code

fixed even more (hopefully all) dropped sound issues in snd_dma

made com_soundmegs SLIGHTLY less broken: now only 2x instead of 3x  :P
note that "soundmegs" are taken FROM THE HUNK now to fix the leak
so you need to increase com_hunkmegs by 2x your com_soundmegs

removed the explicit and incorrect "fastsky==1 == disable portals" test

r_noportals is not a cheat var

hyperspace is a bit less annoying

purged the unused (never finished) idMD4 model code

fixed some bugs in referencedpak list generation

fixed roqs ignoring s_volume

fixed widescreen modes crashing on listen servers

fixed downloads not completing properly


18 Feb 08 - 1.41

removed all bs references to GT_SINGLE_PLAYER and ui_singlePlayerActive
(except from the bot code, which has bigger problems)
added sv_singleplayer

improved TTF overhead a lot: now as fast as crappy bitmap fonts  :D

removed the stupidity of every key aborting demo playback: now ESC only

only play the id logo cin the FIRST time, not every fkn time

removed the broken stencil/projection shadow code

avis produced by \video actually work (bug+fix both from ioq3)

fixed some ABSURD buffer overruns and broken code in snd_dma
which caused random dropped sounds for no reason
it's a miracle it doesn't segfault any real OS
also dumped the unused-since-TA adpcm/mulaw/etc cruft

fixed a TA-era (surprise, surprise) bug that broke loopsound behavior

loop (ie ambient) sounds are now 75% volume

q3config is NEVER autowritten just because of bind/cvar changes
it sucks if you're playing and it sucks even more if you're on GTV
UI/SP code should write it EXPLICITLY if they want to save something


19 Dec 07 - 1.40

the code now requires a C++ compiler
MASSIVE cleanups of the codebase, tho still plenty of bits left

screenshot filename is YYYY_MM_DD-HH_MM_SS-TTT
this means they'll never collide *; moviemakers won't run out;
and the engine DOESN'T STAT 10,000 FILES EVERY FRAME
(* except at 2am on an autumn night if you're amazingly unlucky :P)

demo filename is YYYY_MM_DD-HH_MM_SS

fixed demos to be MAX_OSPATH instead of MAX_QPATH, ie 256 chars now

removed support for IPX

removed in_logitechbug

updated cpu detection

added TTF support

fixed a bunch of stuff in ScanAndLoadShaderFiles, but it's still crap

fixed the patch collision epsilon bugs of 1.34

reverted to id's tab-completion since ioq3's is so hated
i've semi-merged them atm, will fix up when i get time

interpreted vm is never used on platforms that support compiled vm

clampmaps and nomip images use GL_CLAMP_TO_EDGE rather than GL_CLAMP

disabled curl until it's brought up to standard

merged platform-specific *_net.* into qcommon/net_ip.cpp, <3 timbo  :)

fixed USERINFO vars not being sent properly during connect

remove some network stuff (buffer sizes and TOS) http://support.microsoft.com/kb/248611


12 Sep 07 - released as 1.34, since it was about time we did  :P

increased default MAX_POLYS to 8K and MAX_POLYVERTS to 32K


Aug 07

fixed a bug in the skybox code that tried to use a 0-length CVA
which makes recent nvidia drivers go into spaz mode 

changed r_ext_multisample default to 0 to stop ix nagging  :P


July 07

added support for curl

improved some network stuff (buffer sizes and TOS)

added support for mouse5-mouse8


1 May 07

remove broken useless cl_freezeDemo and make demo pausing work
just use timescale 0


27 Apr 07

ripped out all support for legacy substandard hw/drivers (ie Voodoo etc)
and r_maskMinidriver

mode 8 corrected to 1280x960

undefined USE_OPENAL

removed GetUserName call

removed stupid+broken r_dlightbacks

created dlight texture correctly

fixed the dlight code

removed the explicit and incorrect "vertexlight==1 == disable dlights" test

removed redundant r_ext_texture_filter_anisotropic

removed retarded cl_consoleHistory

removed redundant cl_autoRecordDemo

shader spew made developer 1

gl extensions spew made developer 1

pak list made fs_debug 1

removed the TA cvars that were hacked into the engine

reordered demo_protocols to reduce spew


====================
=== Known issues ===
====================

iss: OBS captures go blank after doing a video restart with the D3D11 back-end
exp: device/swap chain re-creation isn't handled by OBS' capture plug-in
