VERSION 1.92.7 (Released 2026-04-02)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.7
Breaking Changes:
- Separator: fixed a legacy quirk where `Separator()` was submitting a zero-height
item for layout purpose, even though it draws a 1-pixel separator.
The fix could affect code e.g. computing height from multiple widgets in order to
allocate vertical space for a footer or multi-line status bar. (#2657, #9263)
The "Console" example had such a bug:
float footer_height = style.ItemSpacing.y + ImGui::GetFrameHeightWithSpacing();
BeginChild("ScrollingRegion", { 0, -footer_height });
Should be:
float footer_height = style.ItemSpacing.y + style.SeparatorSize + ImGui::GetFrameHeightWithSpacing();
BeginChild("ScrollingRegion", { 0, -footer_height });
When such idiom was used and assuming zero-height Separator, it is likely that
in 1.92.7 the resulting window will have unexpected 1 pixel scrolling range.
- Multi-Select: renamed `ImGuiMultiSelectFlags_SelectOnClick` to `ImGuiMultiSelectFlags_SelectOnAuto`.
Kept inline redirection enum (will obsolete).
- Combo(), ListBox(): commented out legacy signatures which were obsoleted in 1.90
(Nov 2023), when the getter callback type was changed from:
bool (*getter)(void* user_data, int idx, const char** out_text)
To:
const char* (*getter)(void* user_data, int idx)
Other Changes:
- TreeNode:
- Moved `TreeNodeGetOpen()` helper to public API. I was hesitant to make this public
because I intend to provide a more generic and feature-full version, but in the meanwhile
this will do. (#3823, #9251, #7553, #6754, #5423, #2958, #2079, #1947, #1131, #722)
- In 'Demo->Property Editor' demonstrate a way to perform tree clipping by fast-forwarding
through non-visible chunks. (#3823, #9251, #6990, #6042)
Using SetNextItemStorageID() + TreeNodeGetOpen() makes this notably easier than
it was prior to 1.91.
- InputText:
- Shift+Enter in multi-line editor always adds a new line, regardless of
`ImGuiInputTextFlags_CtrlEnterForNewLine` being set or not. (#9239)
- Reworked `io.ConfigInputTextEnterKeepActive` mode so that pressing Enter will
deactivate/reactivate the item in order for e.g. `IsItemDeactivatedAfterEdit()`
signals to be emitted the same way regardless of that setting. (#9001, #9115)
- Fixed a glitch when using `ImGuiInputTextFlags_ElideLeft` where the local x offset
would be incorrect during the deactivation frame. (#9298)
- Fixed a crash introduced in 1.92.6 when handling `ImGuiInputTextFlags_CallbackResize`
in certain situations. (#9174)
- Fixed selection highlight Y1 offset being very slightly off (since 1.92.3). (#9311) [@v-ein]
- InputTextMultiline: fixed an issue introduced in 1.92.3 where line count calculated
for vertical scrollbar range would be +1 when the widget is inactive, word-wrap is
disabled and the text buffer ends with '\n'. Fixed a similar issue related to clipping
large amount of text.
- InputTextMultiline: avoid going through reactivation code and fixed losing revert value
when activating scrollbar.
- InputTextMultiline: fixed an issue where edit buffer wouldn't be reapplied to back
buffer on the `IsItemDeactivatedAfterEdit()` frame. This could create issues when
using the idiom of not applying edits before `IsItemDeactivatedAfterEdit()`.
(#9308, #8915, #8273)
- Tables:
- Allow reordering columns by dragging them in the context menu. (#9312)
- Context menu now presents columns in display order. (#9312)
- Fixed and clarified the behavior of using `TableSetupScrollFreeze()` with columns>1,
and where some of the columns within that range were Hidable.
- Before: `TableSetupScrollFreeze(N, 0)`: include the N left-most visible columns as
part of the scroll freeze. So if you intentionally hide columns <N, the scroll
freeze area would start covering the subsequent/following columns (N+1) etc.
- After: `TableSetupScrollFreeze(N, 0)`: include the N left-most columns (regardless of visibility),
part of the scroll freeze. So if you intentionally hide columns <N, the scroll as
freeze area will cover less columns.
- This is generally more sane and logical.
- Fixed dragging a header to reorder outside of visible bounds (due to horizontal scrolling)
from losing active id.
- Angled Headers: angled section for column being reordered via the regular headers
stays highlighted during reordering.
- Style:
- Fonts: fixed an issue introduced in 1.92.6 where `style.FontBaseSize` would be
cleared during the first frame if no fonts was explicitly added before.
- Border sizes are now scaled (and rounded) by `ScaleAllSizes()`.
- When using large values with `ScallAllSizes()`, the following items thickness
are scaled to integer amounts:
- `InputText()` caret/cursor thickness. (#7031)
- `CloseButton()` thickness.
- `TextLink()` underline thickness.
- `ColorButton()` border thickness.
- `Separator()` thickness, via scaling newly added `style.SeparatorSize`. (#2657, #9263)
- Nav:
- Popups: Shift+F10 or Menu key can now open popups menus when using
`BeginPopupContextItem()`, `BeginPopupContextWindow()` or `OpenPopupOnItemClick()`.
(#8803, #9270) [@exelix11, @ocornut]
- Changed Gamepad mapping for "Activate with Text Input" action: (#8803, #787)
- Previously: press North button (PS4/PS5 triangle, Switch X, Xbox Y).
- Now: long press (hold) Activate button (PS4/PS5 cross, Switch B, Xbox A) for ~0.60 secs.
This is rarely used, somehow easier to discover, and frees a button for other uses.
See updated Gamepad Control Sheets: https://www.dearimgui.com/controls_sheets
- Short Gamepad Activation press on InputText() always activate with Text Input mode.
- Popups: pressing North button (PS4/PS5 triangle, SwitchX, Xbox Y) also open popups menus.
- Multi-Select:
- Added `ImGuiMultiSelectFlags_SelectOnClickAlways` mode (rarely used).
This prevents Drag and Drop of multiple items, but it allows to start a new Box-Selection
from inside an existing selection (Excel style). (#9307, #1861)
- Clipper:
- Clear `DisplayStart`/`DisplayEnd` fields when `Step()` returns false.
- Added `UserIndex` helper storage. This is solely a convenience for cases where
you may want to carry an index around.
- Always pulls current context on `ImGuiListClipper::Begin()`, consistent with public
API design, and avoids issues with clipper instances outliving contexts. (#9324, #5856)
- Scrollbar:
- Implemented a custom tweak to extend hit-testing bounding box when window is sitting
at the edge of a viewport (e.g. fullscreen or docked window), so that e.g. mouse the
mouse at the extreme of the screen will reach the scrollbar. (#9276)
- Fixed an issue which could lead initial click to move the current scroll by a pixel.
- Button:
- Moved `ImGuiButtonFlags_AllowOverlap` from imgui_internal.h to imgui.h,
as a convenience for when using e.g. `InvisibleButton()`.
- Focus: fixed fallback "Debug" window temporarily taking focus and setting `io.WantCaptureKeyboard`
for one frame on e.g. application boot if no other windows are submitted. (#9243)
- DrawList:
- PathArcTo(): fixed erroneous segment count for pathologically small arcs on large
circles. (#9331, #9313) [@thedmd, @epajarre]
- Memory:
- Discard/GC of ImDrawList buffers for unused windows favor restoring them to
~Size*1.05 instead of Capacity when awakening again. Facilitate releasing ImDrawList
buffers after unusual usage spike. (#9303)
- Fixed `GetForegroundDrawList()`/`GetBackgroundDrawList()` per-viewport buffers not being
collected when unused for `io.ConfigMemoryCompactTimer` amount of time. (#9303)
- Demo: fixed `IMGUI_DEMO_MARKER` locations for examples applets. (#9261, #3689) [@pthom]
- Misc: added missing ImVec2/ImVec4 operators. (#9339, #8258) [@dkosmari, @ArashPartow]
- Internals:
- ButtonBehavior: fixed internal/low-level `ImGuiButtonFlags_PressedOnRelease`
(as well as equivalent `ImGuiSelectableFlags_SelectOnRelease` for Selectable) from
not taking current active id. `ImGuiButtonFlags_NoHoldingActiveID` allows that.
This was only used internally by MenuItem().
- Backends:
- DirectX9, OpenGL2, OpenGL3, Metal, SDLGPU3, SDLRenderer2, SDLRenderer3: fixed easy-to-fix
issues in code assuming ImTextureID_Invalid is always defined to 0. (#9295, #9310)
- GLFW: mouse cursor is properly restored if changed by user app/code while using
`glfwSetInputMode(..., GLFW_CURSOR_DISABLED)` or `ImGuiConfigFlags_NoMouseCursorChange`.
Amend optimization done in 1.92.6.
- SDLGPU3: removed unnecessary call to `SDL_WaitForGPUIdle()` when releasing
vertex/index buffers. (#9262) [@jaenis]
- WebGPU: fixed version check for Emscripten 5.0.0+.
- WebGPU: removed support for Emscripten <4.0.10. (#9281) [@ypujante]
- WebGPU: added support for WGVK native backend via `IMGUI_IMPL_WEBGPU_BACKEND_WGVK`,
using SPIRV shaders if WGSL is not available. (#9316, #9246, #9257) [@r-lyeh]
(WGVK is a lightweight alternative to Dawn or WGPU for native applications,
which is easier to build/setup, see: https://github.com/manuel5975p/WGVK)
- Examples:
- Emscripten: added `tabindex=-1` to canvas in our shell_minimal.htm. Without it,
the canvas was not focusable in the DOM, which in turn make some backends
(e.g. pongasoft/emscripten-glfw) not receive focus loss events. (#9259) [@pthom]
- Emscripten: fixed minor rendering issues with our HTML shell. (#9281) [@ypujante]
- hidden small blue outline when canvas is focused on Chrome.
- hidden scrollbar in Firefox.
- Vulkan: added `ImGui_ImplVulkan_PipelineInfo::ExtraDynamicStates[]` to allow specifying
extra dynamic states to add when creating the VkPipeline. (#9211) [@DziubanMaciej]
- Vulkan: `ImGui_ImplVulkan_AddTexture()` skips updating descriptor_set if failing
to allocate one. (#8677) [@micb25]
- WebGPU: fixed undefined behaviors in example code for requesting adapter
and device. (#9246, #9256) [@r-lyeh]
- SDL2+WebGPU: fixed hi-dpi handling. (#9300) [@ypujante]
- GLFW/SDL2/SDL3+WebGPU: added support for WGVK. (#9316, #9246, #9257) [@r-lyeh, @ocornut]
- GLFW/SDL2/SDL3+WebGPU: removed support for Emscripten <4.0.10. (#9281) [@ypujante]
Docking+Viewports Branch:
- Viewports:
- Fixed an issue where the implicit "Debug" window would erroneously be targetted for
mouse inputs while hidden if (1) the implicit "Debug" window was used in a previous
session and moved to a secondary viewport and (2) the Platform Backend does not
support the ImGuiBackendFlags_HasMouseHoveredViewport feature. (#9254)
- Backends: SDL2, SDL3: fixed an issue dated 2025/04/09 (1.92 WIP) where a refactor
and a merge caused ImGuiBackendFlags_HasMouseHoveredViewport to never be set, causing
foreign windows to be ignored when deciding of hovered viewport. (#9284) [@ravencgg]
- Backends: SDL3: use SDL_HAS_EVENT_DISPLAY_USABLE_BOUNDS_CHANGED (SDL 3.4.0+) when
available to avoid refreshing monitor work area every frame on Windows. (#8415)
- Backends: Win32: fixed setting/getting correct size when viewports have OS decorations
enabled (e.g. io.ConfigViewportsNoDecoration = false) and process is running in
Per-Monitor V2 DPI mode. (#8897) [@lailoken]

Breaking Changes:

- The default selection is based on (style.FontSizeBase * FontScaleMain * FontScaleDpi)
reaching a small threshold, but old codebases may not set any of them properly.
As as a result, it is likely that old codebase may still default to AddFontDefaultBitmap().
- Prefer explicitly calling either of them based on your own logic!
You can call AddFontDefaultBitmap() to ensure legacy behavior.

- Fixed handling of `ImFontConfig::FontDataOwnedByAtlas = false` which did
erroneously make a copy of the font data, essentially defeating the purpose
of this flag and wasting memory (undetected since July 2015 and now spotted
by @TellowKrinkle, this is perhaps the oldest bug in Dear ImGui history,
albeit for a rarely used feature!) (#9086, #8465)
HOWEVER, fixing this bug is likely to surface bugs in user/app code:
- Prior to 1.92, font data only needs to be available during the atlas->AddFontXXX() call.
Since 1.92, font data needs to available until atlas->RemoveFont(), or more typically
- Prior to 1.92, font data only needs to be available during the `atlas->AddFontXXX()` call.
Since 1.92, font data needs to available until `atlas->RemoveFont()`, or more typically
until a shutdown of the owning context or font atlas.
- The fact that handling of `FontDataOwnedByAtlas = false` was broken bypassed
the issue altogether.
- Removed ImFontConfig::PixelSnapV added in 1.92 which turns out is unnecessary
(and misdocumented). Post-rescale GlyphOffset is always rounded.
- Popups: changed compile-time 'ImGuiPopupFlags popup_flags = 1' default value to be '= 0' for
BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick().

- Before this version, those functions had a 'ImGuiPopupFlags popup_flags = 1' default
- Before this version, those functions had a `ImGuiPopupFlags popup_flags = 1` default

while changing the signature from 'int mouse_button' to 'ImGuiPopupFlags popup_flags'
while changing the signature from `int mouse_button` to `ImGuiPopupFlags popup_flags`
and trying to preserve then-legacy behavior.
- We have now changed this behavior to: cleanup a very old API quirk, facilitate use by
bindings, and to remove the last and error-prone non-zero default value. Also because we
deemed it extremely rare to use those helper functions with the Left mouse button!
As using the LMB would generally be triggered via another widget,
e.g. a Button() + a OpenPopup()/BeginPopup() call.
