Changes

Breaking Changes:

• TreeNode: Fixed a layout inconsistency when using a empty/hidden label followed by a SameLine() call. (#7505, #282)

     Before: TreeNode("##Hidden"); SameLine(); Text("Hello");
             // This was actually incorrect! BUT appeared to look ok with the default style
             // where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).
     After:  TreeNode("##Hidden"); SameLine(0, 0); Text("Hello");
             // This is correct for all values in style.

• With the fix, IF you were successfully using TreeNode("")+SameLine(); you will now have extra spacing between your TreeNode and the following item. You'll need to change the SameLine() call to SameLine(0,0) to remove this extraneous spacing. This seemed like the more sensible fix that's not making things less consistent. (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).

Other Changes

• Windows: Changed default ClipRect to extend to windows' left and right borders, instead of adding arbitrary WindowPadding.x * 0.5f space on left and right. That ClipRect half-padding was arbitrary/confusing and inconsistent with Y axis. It also made it harder to draw items covering whole window without pushing an extended ClipRect. Some items near windows left and right edge that used to be clipped may be partly more visible. (#3312, #7540, #3756, #6170, #6365)
• Windows: Fixed subsequent Begin() append calls from setting last item information for title bar, making it impossible to use IsItemHovered() on a Begin()-to-append, and causing issue bypassing hover detection on collapsed windows. (#7506, #823)
• Fonts: Fixed font ascent and descent calculation when a font hits exact integer values. It is possible that some prior manual use of ImFontConfig::GlyphOffset may become duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC]
• TreeNode: Added ImGuiTreeNodeFlags_SpanTextWidth to make hitbox and highlight only cover the label. (#6937) [@dimateos]
• Tables: Angled headers: fixed multi-line label display when angle is flipped. (#6917)
• Tables: Angled headers: added style.TableAngledHeadersTextAlign and corresponding ImGuiStyleVar_TableAngledHeadersTextAlign variable. Default to horizontal center. (#6917) [@thedmd, @ocornut]
• ProgressBar: Added support for indeterminate progress bar by passing an animated negative fraction, e.g. ProgressBar(-1.0f * GetTime()). (#5316, #5370, #1901)[@gan74]
• Text, DrawList: Improved handling of long single-line wrapped text. Faster and mitigate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)
• Backends: OpenGL3: Detect ES3 contexts on desktop based on version string, to e.g. avoid calling glPolygonMode() on them. (#7447) [@afraidofdark, @ocornut]
• Backends: OpenGL3: Update loader for Linux to support EGL/GLVND. (#7562) [@ShadowNinja, @vanfanel]
• Backends: Vulkan: Added convenience support for Volk via IMGUI_IMPL_VULKAN_USE_VOLK define. (you could always use IMGUI_IMPL_VULKAN_NO_PROTOTYPES + ImGui_ImplVulkan_LoadFunctions() as well). (#6582, #4854) [@adalsteinnh, @kennyalive, @ocornut]
• Backends: SDL3: Fixed text inputs. Re-enable calling SDL_StartTextInput()/SDL_StopTextInput() as SDL3 no longer enables it by default. (#7452, #6306, #6071, #1953) [@Green-Sky]
• Examples: GLFW+Vulkan, SDL+Vulkan: Added optional support for Volk. (#6582, #4854)
• Examples: GLFW+WebGPU: Added support for WebGPU-native/Dawn (#7435, #7132) [@eliasdaler, @Zelif]
• Examples: GLFW+WebGPU: Renamed example_emscripten_wgpu/ to example_glfw_wgpu/. (#7435, #7132)

Changes from 1.90.5 to 1.90.6 related to the Docking branch:

• Docking: when io.ConfigDockingWithShift is enabled, fixed help tooltip erroneously reading SetNextWindowXXX() data. (#6709, #4643, #7491) [@ocornut, @cfillion]
• Viewports: fixed outer-right edge of MenuBar clipping rectangle off by one when window is located on a monitor with negative coordinates. (#6861, #2884) [@cfillion]
• Backends: Vulkan: reworked swap-chain resize handling for secondary viewports, fix for typical Linux setups. (#2626, #3390, #3758, #7508, #7513) [@RoryO, @InsideBSITheSecond]
• Backends: Vulkan: create a custom pipeline for secondary viewports. Fixes issues when user created main viewport uses a different renderpass. (#6325, #6305, #7398, #3459, #3253, #3522) [@skaman, @FunMiles]

Changes from 1.90.3 to 1.90.6 related to the Range-Select branch: (previous release notes skipped a few)

• RangeSelect/MultiSelect: (Breaking) merge ImGuiSelectionRequestType_Clear and ImGuiSelectionRequestType_SelectAll into ImGuiSelectionRequestType_SetAll, rename ImGuiSelectionRequest::RangeSelected to Selected.
• RangeSelect/MultiSelect: Simplified ImGuiSelectionBasicStorage by using a single SetItemSelected() entry point.
• RangeSelect/MultiSelect: Added ImGuiMultiSelectFlags_NoAutoSelect, ImGuiMultiSelectFlags_NoAutoClear features.
• RangeSelect/MultiSelect: Added Checkbox Demo.
• RangeSelect/MultiSelect: Box-Select: fix preventing focus. amend determination of scope_hovered for decorated/non-child windows + avoid stealing NavId. (#7424)
