Changes in v1.93.0 (since v1.92.9b)

🆘 PS: v1.92.8 contained a signature change for the trailing optional parameters of ImDrawList::AddRect(), AddPolyline(), PathStroke(). C++ users should be notified at compile-time, but languages without type-checking may only be notified at runtime. Read v1.92.8 if using non a C++ language. Consider enabling IMGUI_DISABLE_OBSOLETE_FUNCTIONS from time to time to get rid of obsolete calls.

In 1.93.0, the ImDrawList rendering API has been improved to be more robust and more consistent over the whole range of shapes. The rendering now matches much closer to common vector drawing APIs, like html canvas. Improvements, like anti-aliased line endings and stroke position were added. The coordinates passed to the API are now consistently describing shape outlines.

For code using custom rendering: some details are now rendered slightly differently (even if generally more consistent). The difference in rendering is in the range of half a pixel, but that can lead to issues like some lines now look blurrier or more transparent. All Dear ImGui widgets should appear identical or better.

The rendering of common shapes was optimized when the shapes fall on integer coordinates (which is most of the UI). This includes skipping anti-aliasing when not needed, or using textures instead of tessellated geometry to draw round corners. The varying code-paths are designed to look indistinguishable from each others.

New rendering code fixes some inconsistencies between graphics APIs (e.g. DirectX vs OpenGL) which are using different diamond exits rules. New code should work precisely the same regardless of which graphics API is used (note that using _StrokeLegacy mode can lead to the same old inconsistencies).

New rendering code also deals better with animating thickness and rounding (integer values are recommended).

While the current version doesn't make lots of visible use of the new features and facilities, they are among the pillars that will make it easier to create prettier contents, both for custom rendering and future versions of the library.

Use ImDrawFlags_StrokeLegacy mode to emulate old rendering:

Per-primitive: draw_list->AddLine(..., ..., ImDrawFlags_StrokeLegacy);
For a given scope: draw_list->PushDrawFlag(ImDrawFlags_StrokeLegacy, true); draw_list->AddLine(...); draw_list->PopDrawFlag();
Globally: ImGui::Checkbox("DefaultsToStrokeLegacy", &io.ConfigDebugDrawListDefaultsToStrokeLegacy); // Map to a checkbox
Globally: io.ConfigDebugDrawListDefaultsToStrokeLegacy = io.KeyShift; // Map on Shift

Don't panic!
Many applications will not notice any difference! You will more likely see differences if you used lots of direct ImDrawList calls for custom rendering.

Breaking Changes

ImDrawList:

AddLine(): removed the (+0.5f,+0.5f) offset that was sneakily added to input coordinates. (#9504)
- This fixes inconsistencies in the API and matches the PathXXX API.
- It seems scary but in reality AddLine() is not used that often and many won't immediately notice the difference.
- By default, stroke thickness extends on both side of the given segment. e.g for a "pixel-perfect" looking line with thickness=1.0f, coords should be passed as center of each ends of the line.
- Use ImDrawFlags_StrokeLegacy to use old offset if required. Or you can apply the offset manually!
- Generally better, simple and faster to use AddLineH(), AddLineV() functions added in 1.92.8.
- READ IF YOU ARE MINDFUL OF PIXEL-PERFECTNESS IN YOUR CUSTOM RENDERING/WIDGETS USING AddLine():
  - TRANSITION GUIDE FOR AXIS-ALIGNED LINES:
    - When switching from legacy AddLine() values to AddLineV(), AddLineH() you can keep same inputs coordinates as before:
      - Old AddLine({x, y1}, {x, y2}, col) --> AddLineV(x, y1, y2, col); // Vertical line.
      - Old AddLine({x1, y}, {x2, y}, col) --> AddLineH(x1, x2, y, col); // Horizontal line.
      - This will be equivalent and faster for thickness=1.0f lines.
    - Since AddLine() use default stroke pos Center and AddLineV(), AddLineH() use Inside, thickness>1.0f strokes will differ. Using ImDrawFlags_StrokeCenter will match old result more closely (aka look centered), but is more likely to look blurry as it already did before.
    - Read table below about StrokePos and the Pixel-Perfect Rendering guide if you care about pixel-perfect lines.
  - TRANSITION GUIDE FOR DIAGONAL LINES:
    - Your lines will appear offset by -0.5f pixels on each axis. Being anti-aliased diagonal lines, they won't look particularly better or worse, just slightly offset. It'll likely only be noticeable if you carefully combined them with other primitives for a pixel-perfect result.
    - Old AddLine({x1, y1}, {x2, y2}, col) --> AddLine({x1 + 0.5f, y1 + 0.5f}, {x2+ 0.5f, y2 + 0.5f}, col); // Same
    - or use ImDrawFlags_StrokeLegacy --> AddLine({x1, y1}, {x2, y2}, col, thickness, ImDrawFlags_StrokeLegacy); // Offset by +0.5f + disable AA ends.
    - This reapplies the old offset, and should get you exactly the same result you previously got for thickness=1.0f lines. But said result were previously sometimes ambiguous and renderer-dependent. (#3116, #3258, #2441)
    - Old code did not support anti-aliased ends, which could create gaps when rendering shapes out of multiple contiguous lines instead of using AddPolyline(). There is a possibility that you legacy code added fudge offsets here and there; which may not be necessary anymore if you use _AALineEnds, or if you combine rendering of contiguous lines using AddPolyline().

  - 🔍Interactive 1.92.9 vs 1.93 Troubleshooting / Testbed w/ commentary.
AddRect(), AddCircle(), AddNgon(), AddEllipse(), AddTriangle(), AddQuad(): defaulting to "inside" stroke.
- All closed shapes with thickness=1.0f will appear identical.
- The difference for thickness>1.0f shapes may be minimal since very large strokes were not well supported for widgets, but stroke will default inside widgets.
AddCircle(), AddNgon(): removed -0.5f offset added to radius.
- This fixes inconsistencies in the API.
- Use ImDrawFlags_StrokeLegacy to use old method if required. Or you can apply the offset manually!
AddRectFilled(): non-integer coordinates will now display anti-aliased edges. Previously, non-integer coordinates rendered with aliased edges snapped by the rasterizer. (#6971)
AddRect(), AddRectFilled(): rectangles with inverted coordinates won't be visible unless using ImDrawFlags_StrokeLegacy mode. With inverted coordinates (min > max):
- Legacy AddRect() rounding off -> visible but incorrect outer size.
- Legacy AddRect() rounding on -> visible but very glitchy.
- Legacy AddRectFilled() rounding off -> visible and correct.
- Legacy AddRectFilled() rounding on -> visible but very glitchy.
- Use ImDrawFlags_StrokeLegacy to use old rendering for cases without rounding, or fix coordinates.
Merged ImDrawListFlags into ImDrawFlags. ImDrawListFlags was rarely used directly and generally setup by the ImGui context. Unifying them allows easily using them for both per-primitives and scope alterations. Kept redirection enums (will obsolete).
- ImDrawListFlags_AntiAliasedLines -> ImDrawFlags_AALines
- ImDrawListFlags_AntiAliasedFill -> ImDrawFlags_AAFill
- ImDrawListFlags_AllowVtxOffset -> ImDrawFlags_UseVtxOffset
- ImDrawListFlags_TextNoPixelSnap -> ImDrawFlags_TextNoPixelSnap
- Renamed all ImDrawFlags_RoundCornersXXX flags to ImDrawFlags_RoundXXX. Kept redirection enums (will obsolete).
  - ImDrawFlags_RoundCornersAll -> ImDrawFlags_RoundAll
  - ImDrawFlags_RoundCornersNone -> ImDrawFlags_RoundNone
  - ImDrawFlags_RoundCornersTopLeft -> ImDrawFlags_RoundTopLeft
  - ImDrawFlags_RoundCornersTopRight -> ImDrawFlags_RoundTopRight
  - ImDrawFlags_RoundCornersBottomLeft -> ImDrawFlags_RoundBottomLeft
  - ImDrawFlags_RoundCornersBottomRight -> ImDrawFlags_RoundBottomRight
  - ImDrawFlags_RoundCornersTop -> ImDrawFlags_RoundTop
  - ImDrawFlags_RoundCornersBottom -> ImDrawFlags_RoundBottom
  - ImDrawFlags_RoundCornersLeft -> ImDrawFlags_RoundLeft
  - ImDrawFlags_RoundCornersRight -> ImDrawFlags_RoundRight
Marked ImDrawListFlags_AntiAliasedLinesUseTex and style.AntiAliasedLinesUseTex as obsolete, as the new line rendering code always uses textures.
Enabling ImFontAtlasFlags_NoBakedLines in the font atlas will now disable support for anti-aliased lines by clearing style.AntiAliasedLines/style.AntiAliasedLineEnds.

Style:

Obsoleted style.CurveTessellationTol (default 1.25) which was in Pixels² unit in favor of style.CurveTessellationMaxError (default 1.12) which is in Pixels unit. It is easier to tweak + this allows us to easily scale error threshold on high density screens. style.CurveTessellationMaxError == sqrtf(style.CurveTessellationTol).

ImGuiTextFilter:

Removed float width parameter of Draw(const char* filter, float width): prefer using SetNextItemWidth(float) which is standard. Kept inline redirection function.

Fonts:

Renamed AddRemapChar() to AddRemapCodepoint() (rarely used, marked internal). (#609, #5748, #9559)

Backends:

DirectX12: Removed support for legacy ImGui_ImplDX12_Init() signature, which was obsoleted in 1.91.6 (December 2014), because it needed to forcefully disable support for ImGuiBackendFlags_RendererHasTextures. Use the new signature! (#9487)
OpenGL3: Does not attempt to read GL_CLIP_ORIGIN by default as the detection is sub-optimal and not reliable on some setup. Use ImGui_ImplOpenGL3_SetClipOrigin(0) to enable auto-detection, or e.g. ImGui_ImplOpenGL3_SetClipOrigin(GL_UPPER_LEFT).

Other Changes

Style:

StyleColorsDark(): minor refresh of the default style to look more modern: changed WindowBg to use a slightly greyer value and removed opacity. changed FrameBg values to use a dark black to make frames stand out better. Tweak TextDisabled, TableHeaderBg, TableBorders to match altered WindowBg.
StyleColorsLight(): inverted ImGuiCol_TitleBgXXX colors so that the selected window title bar appears brighter.

DrawList:

Added flags to specify stroke position in all ImDrawList stroking functions: (#9504) [@memononen]
- ImDrawFlags_StrokeInside (default for Rect, Circle/Ellipse, Triangle, Quad, Ngon + AddLineH, AddLineV)
- ImDrawFlags_StrokeCenter (default for Line, Polyline, Beziers, Paths function)
- ImDrawFlags_StrokeCenterBiased (center w/ bias for pixel perfect alignment)
- ImDrawFlags_StrokeOutside
- ImDrawFlags_StrokeLegacy (match old behavior)
- Legacy mode may be set as default for a given scope using PushDrawFlag(ImDrawFlags_StrokeLegacy, true).
- Legacy code was generally applying +0.50f offsets which meant that,
  - with thickness=1.0f: the stroke would appear inside.
  - with thickness>1.0f: the stroke would start expanding on both sides but starting from that small initial offset.
  - with thickness>1.0f for even integer values, the stroke would look blurry.
  - TL;DR; the logic didn't make much sense for thickness>1.0f.
- Defaulting to Inside for closed shapes ensure that rectangles and lines are never blurry, regardless of thickness, as long as input coordinates/sizes are integers. (#9359) Recap:

Thickness	Legacy	Inside	Outside	Center	CenterBiased
1.0f	sharp	sharp	sharp	blurry	sharp
2.0f	blurry	sharp	sharp	sharp	sharp
3.0f	sharp	sharp	sharp	blurry	sharp

Troubleshoot with our interactive 1.92.9 vs 1.93.0 comparing testbed: https://www.dearimgui.com/docs/drawlist_v193

AddPolyline(), PathStroke(), AddTriangle(): the algorithm to render lines got overhauled. (#9504, #2183, #2964, #7972 + #9360, #6331, #4250, #4091) [@memononen]
- Generally fixed rendering of thick strokes/paths.
- The new stroke expansion now uses corner miter calculation, which keeps thickness along the line segments consistent. If the corner becomes too sharp, it will be beveled to avoid long spikes at corners.
- There are also some robustness measures for the case where the line thickness is larger than the features being drawn.
- Rendering artifacts are still possible when the path features are smaller than line thickness, but the artifacts should be more localized. The new implementation attempted to favor simple implementation and robustness over the corner case accuracy.
All functions: new rendering code fixes some inconsistencies between graphics APIs (e.g. DirectX vs OpenGL) which are using different diamond exits rules. New code should work precisely the same regardless of graphics API. (#3116, #3258, #2441) [@memononen]
Debug: added io.ConfigDebugDrawListDefaultsToStrokeLegacy to facilitate comparing old/new behaviors. This is equivalent to calling PushDrawFlag(ImDrawFlags_StrokeLegacy, true) on every drawlists. Suggested uses:
- e.g. io.ConfigDebugDrawListDefaultsToStrokeLegacy = io.KeyShift; // Map on holding Shift
- e.g. ImGui::Checkbox("DefaultsToStrokeLegacy", &io.ConfigDebugDrawListDefaultsToStrokeLegacy);

Added ImDrawFlags_AALineEnds flag to enable anti-aliased line ends.
- Most noticeable for thick lines.
- Also helps fill minor gaps if combining multiple individual lines. For best looking continuous lines you should use AddPolyline(), it creates joins between line segments to avoid any gaps.
- Added style.AntiAliasedLineEnds in ImGui to set default state.
- This is disabled by default! Enabling AA Ends by default would be more "correct", but since it is very slightly slower and increases vertex/index data we decided to not enable it by default. This keeps situations such as "throw tens of thousands of lines at ImDrawList" optimal. You can opt-in for a given shape or in a scope using PushDrawFlag().
Added ImDrawFlags_JoinMiter flag to disable using beveled corner.
- Closer to legacy rendering and slightly faster, but corners sharper than 90 degrees may expand far out.
  - Automatically used by AddRect(), AddCircle(), AddNgon(), AddEllipse() functions since we know that the input path does not contain sharper corners.
Added ImDrawFlags_CapSquare flag to extend lines ends using square caps. (#9360)
AddConvexPolyFilled()/PathFillConvex(): improved to handle input geometry more robustly. The rendering of sharp corners was improved. Earlier there were issues with sharp corners either creating long spikes, or messing up the adjacent edge's anti-aliasing. Now the anti-aliasing fringe calculation is more consistent, and sharp corners get beveled to avoid spikes. There might still be issues when the smallest extent of a long thin polygon is less than a pixel. Also supports ImDrawFlags_JoinMiter, to facilitate matching a stroke using the same flag. [@memononen]
AddRect(), AddRectFilled(): various optimizations for rounded rectangles. (#1962, #9504)
- Integer-aligned coordinates and thicknesses will automatically use baked textures, saving on both CPU and vertex/index data.
- Enabled by default. Use ImFontAtlasFlags_NoBakedRoundCorners to disable baking round corners in font atlas.
- Added ImDrawFlags_UseTexForRoundCorners flag to enable in scope or per-shape. Added for consistency and debugging, not really needed in practice.
AddCircle(), AddCircleFilled(): fixed large circles being under-tessellated (when above ~140 with default CircleTessellationMaxError).
Improved debug-build performance in various locations.
Improved minor mismatches when overlapping strokes and filled shapes.
For example, when using inside strokes,
- AddRect() and AddRectFilled() with rounding now overlap better. (#3656)
- AddCircle() and AddCircleFilled() now overlap better.
Added ImDrawList::PushDrawFlag()/PopDrawFlag() to alter certain flags for a scope and a given ImDrawList. (#9489)
- e.g. PushDrawFlag(ImDrawFlags_StrokeLegacy, true); enforce legacy tweaks.
About ImDrawFlags_StrokeLegacy:
- This is designed to emulate old behavior:
  - Most shapes use ImDrawFlags_StrokeCenter.
  - AddLine() add +0.5f,+0.5f offset to position.
  - AddRect() and AddRectFilled() allow inverted positions.
  - AddRectFilled() has no AA when passed non-integer coordinates.
  - AddCircle(), AddNgon() add a -0.5f offset to radius.
  - Closed shapes use miter corners.
  - Lines don't have anti-aliased ends.
- But there are known difference between legacy code and ImDrawFlags_StrokeLegacy:
- Thick shapes with acute angles will now preserve thickness better, which may make them appear as protruding a little more.
- About disabling anti-aliasing:
  - Disabling anti-aliasing is now emulated by applying different UV coordinates.
    - It does not result in a performance increase or vertex/index data decrease any more (however the tendency is that the new code behaves better than old code).
    - But may be a useful stylistic choice in some circumstances.
  - Many thick shapes had broken corners with old no-AA code, and the old no-AA code was wildly different from the AA code. Not the case any more. (#288)
Per-viewport FramebufferScale for Apple/Retina screen is applied to draw lists:
- AA Fringe is scaled accordingly. (#9577)
- Circle and Curves tessellation error are scaled accordingly.
Reworked assert in PushTexture() to allow convenience grace period of using a texture that was queue for destroy during the frame. Make it safe to stick to an existing texture during the frame. (#9528, #8465)
Added optional platform_io.DrawCallback_SetSamplerFromTex standard backend-agnostic draw callback for requesting to use the sampler associated already associated to a texture. Currently only supported by the OpenGL2/3 and SDLRenderer3 backend. (#9378)
Fixed dangling ImDrawList::_OwnerName when using animated label. (#9552) [@ubi-dcastonguay]

Mixed Values:

Added ImGuiItemFlags_MixedValue flag for representing mixed/indeterminate values. Supported by: Checkbox(), RadioButton(), DragXXX(), SliderXXX(), InputXXX(), ColorXXX() and Combo() functions. The scoped flag is designed for usage by advanced property editors. (#5518, #5677, #6865)

Drags, Sliders:

Ongoing drags may be cancelled using Right-Click, Escape or Gamepad Triangle. Cancelling reverts to the initial value. (#8564, #9534)
Fixed an overflow using ImGuiSliderFlags_Logarithmic with S32/S64 types which leads to clamped interactions. (#9526, #3361, #1823, #1316, #642) [@lailoken]

Tree Nodes:

Fixed issues/asserts with 32+ deep trees when using ImGuiTreeNodeFlags_DrawLinesXXX features or other features requiring stack storage. (#9509) [@lasrod]

Tab Bars:

Improved scroll target when clicking a Tab that is larger than the scrolling section width.
Using <> scrolling buttons while the selected Tab is at either end of the section mid-section but not fully visible always makes it fully visible (before eventually selecting a Tab in the leading/trailing section).

Tables:

Fixed a bug restoring correct .ini columns order when table use is Sortable but had no user changes. (regression from 1.92.9). (#9519, #9108)
Fixed a bug tracking topology changes (insert new columns in the middle) when the table is not _Reorderable: new columns would be ordered incorrectly. (#9570, #9108, #9572) [@lailoken]

InputText:

Fixed a crash in some cases when using Home key in a WordWrap+ReadOnly field. (#9561)

Selectable:

Fixed ImGuiSelectableFlags_SelectOnNav triggering during NavInit.

Fonts:

Reworked AddFontDefault() to use io.DisplayFrameBufferScale as part of the heuristic to select AddFontDefaultVector() by default, effectively using ProggyForever instead of ProggyClean on most Apple/Retina setups by default.
Added ImFont::AddRemapCodepointToGlyphIndex() allowing to access glyphs that are not mapped to codepoints. (#9559, #5647, #609, #5748, #8466)
imgui_freetype: Fixed blurriness rendering AddFontDefaultVector(). Caused by a non-pixel aligned offset caused by ExtraSizeScale. (#9348, #9233) [@redpartizan, @RDMCz]
(Internal) ImFontLoader: reworked FontSrcContainsGlyph, FontBakedLoadGlyph signatures to take raw glyph index instead of codepoint. Added FontSrcGetGlyphIndexFromCodepoint. (#9559, #5647, #9540, #8466, #8465)
Added IMGUI_DISABLE_STB_TRUETYPE to completely omit the stb_truetype loader code + stb_truetype.h code. (#9573)

ColorEdit:

ColorButton(), ColorEdit4(), ColorPicker4(): cancel-out alpha caused by BeginDisabled() so disabled color buttons have the same color as non-disabled ones. (#9511)
ColorButton(): fixed issues/inconsistencies with checkerboard rendering when combining color alpha and global style alpha. (#9511) [@enjmiah, @ocornut]

Popups:

Amended context menu right-click opening code to check that the right-click hasn't been owned by another items. This is more correct and also necessary to avoid Drags/Sliders cancelling also triggering a cancel menu. (#8564, #9534)
Reworked GetMousePosOnOpeningCurrentPopup() to be legal to call within the BeginPopup()/EndPopup() scope of a popup which was just closed. (#9551) [@jkunstwald]

ImGuiTextFilter:

Added support for space as an "and" filter, which is the standard. (#2435, #30) e.g. w/ filter 'hello world' (without quotes) both words needs to be in input data.
Added support for double-quoted "xxx" blocks to e.g. match words sequences. (#2435) e.g. w/ filter "hello world" the exact sequence needs to be in input data.
Fixed filtering when mixing "include" and "-exclude" keyword so that an "-exclude" match always filters out. (#2435) [@kudaba, @ocornut]
Added DrawWithHint() function. (#6206, #6395, #6447)
Added a "incl -excl" hint by default when the search field is empty. (#6206, #6395, #6447)

Widgets:

Checkbox, Menus: check marks use anti-aliased ends.
Tweaked rendering in various locations to avoid blurriness:
- Windows: title-bar and menu-bar border (when thickness>1.0f).
- SeparatorText: border (when thickness>1.0f).
- Tree: hierarchy lines (when thickness>1.0f).
- InputText: input caret (when thickness>1.0f).
- TabBar: selected overline border (when thickness>1.0f).

Misc:

Fixed GetBackgroundDrawList()/GetForegroundDrawList() not being properly reset every frame when accumulated session time is very large (e.g. a few days). [@lailoken]
Added IM_NODEBUGSTEP helper to tag functions with __declspec(non_user_code) (MSVC) or [[gnu::artificial]] (Clang/GCC) in order to provide a hint to debuggers to skip trivial functions when stepping into.
Tagged various trivial functions using IM_NODEBUGSTEP: ImVec2(), ImVec4() etc. and various operators.
Fixed strict aliasing violation in ImHashData() affecting Clang 23 + SSE 4.2 + -flto. Could manifest as ImFontAtlasBakedGetId() computation omitting font size from the hashed data. (#9557, #9560) [@sthalik]
IO: restore default clipboard/ime/shell platform handlers on ClearPlatformHandlers(), fixing issues switching backends mid-session to one relying on default. (#9537, #8945, #2769) [@lstalmir]

Demo:

Added Widgets->Mixed Values section. (#5518, #5677, #6865)
Custom Rendering section: exposed new flags; showcasing overlapping strokes and filled shapes; added an option to animate thickness; added new shapes to showcase new rendering features that previously hit limitations.
Style Editor: fixed style/colors combo box applying style when opening Combo.

Backends:

QNX: added QNX Screen backend. (#9492) [@mgorchak-blackberry]
Metal, Metal4: added support for rendering inside a render pass with multiple color attachments (e.g. when merged with other passes): we render to the first color attachment and leave the other ones untouched. (#9574) [@tqjxlm]
OpenGL2, OpenGL3: added support for platform_io.DrawCallback_SetSamplerFromTex draw callback to request using the sampler associated already associated to a texture. (#9378)
OpenGL2, OpenGL3: fixed DrawCallback_ResetRenderState handler not resetting all states in the glTexParameter() path. (#9378)
OpenGL3: added ImGui_ImplOpenGL3_SetClipOrigin() to specify origin between GL_LOWER_LEFT (new default), GL_UPPER_LEFT and 0 (autodetect, old default).
OpenGL3: avoid querying glGetIntegerv(GL_CLIP_ORIGIN) multiple times when using when using default and using DrawCallback_ResetRenderState, at it appear to stall some drivers. (#2186, #3998, #3146, #3143, #8640)
SDL2: fixed querying framebuffer scale/density when using Metal without going through a SDL_Renderer. (#5592) [@lailoken]
SDLRenderer3: restore any temporarily modified texture scale modes at the of RenderDrawData(). (#9378)
SDLRenderer3: expose CurrentScaleMode in ImGui_ImplSDLRenderer3_RenderState. (#9543, #9378) [@Clownacy]
SDLRenderer3: added support for platform_io.DrawCallback_SetSamplerFromTex draw callback to request using the sampler associated already associated to a texture via SDL_SetTextureScaleMode(). (#9378) It is equivalent to setting render_state->CurrentScaleMode = SDL_SCALEMODE_INVALID. Note: this callback is only supported by selected rendering backends: most other graphics API don't have the equivalent of SDL_SetTextureScaleMode() and the callback won't work with them.
Vulkan: added for support for multiple Vulkan contexts with custom loaders. (#6616) [@lstalmir]
Vulkan: added support for rendering inside a render pass with multiple color attachments (e.g. when merged with other passes): we render to the first color attachment and leave the other ones untouched. (#9574) [@tqjxlm]
WebGPU: fixed passing non-integer sizes to wgpuRenderPassEncoderSetViewport() when FramebufferScale is >1.0f. (#9515, #8628) [@WayU]
WebGPU: update to build with wgpu-native 29.0+. (#9377, #9532, #9530) [@lucascompython, @ivan-enzhaev]

camomill is an application for generating 5-axis toolpaths for CNC machines. It aims to be a cost-effective (buy once, perpetual license) Computer-Aided Manufacturing (CAM) tool with a focus on the 5-axis operations that are traditionally reserved for very expensive industrial-grade software suites.

https://github.com/ngwg/ceasta
"win32 + dx11 on windows, glfw + opengl3 on linux and macos (the mac build is one universal .app; the window works in points and 1.92's dynamic fonts render at the retina density). a plain fixed layout with splitters instead of docking, ImGuiListClipper for the listing and every table, the function graph drawn with ImDrawList, and a command palette for every action. three themes: dark, light and high contrast."

@ExtasyHosting: "Custom firmware on a FlySky TX. It’s always a pleasure getting ImGui running on embedded hardware"

@Zaryob: ImShark — a packet analyzer built with Dear ImGui
"I started ImShark in 2023 as a small project to learn how network packets and protocols work, using Dear ImGui to inspect them visually. Over time, it grew into a Wireshark-inspired desktop application, with live packet capture alongside offline capture analysis."
