Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4, v1.89.5, v1.89.6, v1.89.7. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

I have been stubbornly deferring tagging 1.90 for while because I wanted to include the range-select feature in it, but it's not done... But there are about 600 lines of changelog between 1.89 and 1.89.8.

Breaking Changes:

• IO: Obsoleted io.ClearInputCharacters() (added in 1.47) as it now ambiguous and often incorrect/misleading considering the existence of a higher-level input queue. This is automatically cleared by io.ClearInputsKeys(). (#4921)
• ImDrawData: CmdLists[] array is now owned, changed from ImDrawList** to ImVector<ImDrawList*>. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). Allocation count are identical. (#6406, #4879, #1878)

Other Changes:

• Fonts: ImFontConfig::OversampleH now defaults to 2 instead of 3, since the quality increase is largely minimal.
• Fonts, imgui_freetype: Added support to render OpenType SVG fonts using lunasvg. Requires enabling IMGUI_ENABLE_FREETYPE_LUNASVG along with IMGUI_ENABLE_FREETYPE, and providing headers/libraries for lunasvg. (#6591, #6607) [@sakiodre]
• ImDrawData: CmdLists[] array is now an ImVector<> owned by ImDrawData rather than a pointer to internal state.
  • This makes it easier for user to create their own or append to an existing draw data. Added a ImDrawData::AddDrawList() helper function to do that. (#6406, #4879, #1878)
  • This makes it easier to perform a deep-swap instead of a deep-copy, as array ownership is now clear. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)
  • Syntax and allocation count are otherwise identical.
• Fixed CTRL+Tab dimming background assert when target window has a callback in the last ImDrawCmd. (#4857, #5937)
• IsItemHovered: Fixed ImGuiHoveredFlags_ForTooltip for Keyboard/Gamepad navigation, got broken prior to 1.89.7 due to an unrelated change making flags conflict. (#6622, #1485)
• InputText: Fixed a case where deactivation frame would write to underlying buffer or call CallbackResize although unnecessary, in a frame where the return value was false.
• Tables: fixed GetContentRegionAvail().y report not taking account of lower cell padding or of using ImGuiTableFlags_NoHostExtendY. Not taking it into account would make the idiom of creating vertically bottom-aligned content (e.g. a child window) inside a table make the parent window erroneously have a scrollbar. (#6619)
• Tables: fixed calculation of multi-instance shared decoration/scrollbar width of scrolling tables, to avoid flickering width variation when resizing down a table hosting a child window. (#5920, #6619)
• Scrollbar: layout needs to take account of window border size, so a border size will slightly reduce scrollbar size. Generally we tried to make it that window border size has no incidence on layout but this can't work with thick borders. (#2522)
• IO: Added io.ClearEventsQueue() to clear incoming inputs events. (#4921)
  May be useful in conjunction with io.ClearInputsKeys() if you need to clear both current inputs state and queued events (e.g. when using blocking native dialogs such as Windows's ::MessageBox() or ::GetOpenFileName()).
• IO: Changed io.ClearInputsKeys() specs to also clear current frame character buffer (what now obsoleted io.ClearInputCharacters() did), as this is effectively the desirable behavior.
• Misc: Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable stb_sprintf implementation when using IMGUI_USE_STB_SPRINTF. (#6626) [@septag]
• Misc: Avoid stb_textedit.h reincluding string.h while in a namespace, which messes up with building with Clang Modules. (#6653, #4791) [@JohelEGP]
• Demo: Better showcase use of SetNextItemAllowOverlap(). (#6574, #6512, #3909, #517)
• Demo: Showcase a few more InputText() flags.
• Backends: Made all backends sources files support global IMGUI_DISABLE. (#6601)
• Backends: GLFW: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFlags_NoMouse if desired. (#5625, #6609) [@scorpion-26]
• Backends: WebGPU: Update for changes in Dawn. (#6602, #6188) [@williamhCode]
• Examples: Vulkan: Creating minimal descriptor pools to fit only what is needed by example. (#6642) [@SaschaWillem]

Changes from 1.89.7 to 1.89.8 related to the docking branch (multi-viewport and docking features):

• Docking, Style: resizing separators use same colors as window borders (ImGuiCol_Border) for consistency. With default styles it doesn't make a big difference. (#2522) [@rmitton] In the future if we promote using thick value for inner/outer docking padding we may need to introduce new colors for it.
• Docking: added style.DockingSeparatorSize, ImGuiStyleVar_DockingSeparatorSize. Now also scaled by style.ScaleAllSizes(). (#3481, #4721, #2522) [@PossiblyAShrub, @wobbier]
• Docking: fixed rendering of docked-window scrollbar above outer border. (#2522)

Changes from 1.89.7 to 1.89.8 related to the range-select branch:

This is hopefully the last batch of breaking changes before merging this in 1.90:

• RangeSelect/MultiSelect: (BREAKING) BeginMultiSelect() doesn't need two last params maintained by users. Moving some storage from user to core.
• RangeSelect/MultiSelect: Added fields in ImGuiMultiSelectIO to facilitate implementing deletion while providing correct scrolling/focus.
• RangeSelect/MultiSelect: Added multi-select deletion demo.

New exciting projects!

Since 1.89 we semi-sneakily soft launched two new entire projects!

Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4, v1.89.5, v1.89.6. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

I have been stubbornly deferring tagging 1.90 for while because I wanted to include the range-select feature in it, but it's not done... But there are about 540 lines of changelog between 1.89 and 1.89.7.

Breaking Changes:

• Moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage. Majority of users are likely to not even notice.
• Overlapping items: (#6512, #3909, #517)
  • Obsoleted SetItemAllowOverlap(): it didn't and couldn't work reliably since 1.89 (2022-11-15), and relied on ambiguously defined design. Use SetNextItemAllowOverlap() before item instead.
  • Added SetNextItemAllowOverlap() (called before an item) as a replacement for using SetItemAllowOverlap() (called after an item). This is roughly equivalent to using the legacy SetItemAllowOverlap() call (public API) + ImGuiButtonFlags_AllowOverlap (internal).
  • Renamed 'ImGuiTreeNodeFlags_AllowItemOverlaptoImGuiTreeNodeFlags_AllowOverlap` for consistency.
  • Renamed ImGuiSelectableFlags_AllowItemOverlap to ImGuiSelectableFlags_AllowOverlap for consistency.
  • Kept redirecting enums (will obsolete).

Other Changes:

• Tooltips/IsItemHovered() related changes:
  • Tooltips: Added SetItemTooltip() and BeginItemTooltip() helper functions.
    They are shortcuts for the common idiom of using IsItemHovered().
    • SetItemTooltip("Hello") == if (IsItemHovered(ImGuiHoveredFlags_Tooltip)) { SetTooltip("Hello"); }
    • BeginItemTooltip() == IsItemHovered(ImGuiHoveredFlags_Tooltip) && BeginTooltip()
      The newly added ImGuiHoveredFlags_Tooltip is meant to facilitate standardizing mouse hovering delays and rules for a given application. The previously common idiom of using 'if (IsItemHovered()) { SetTooltip(...); }' won't use delay or stationary test.
  • IsItemHovered: Added ImGuiHoveredFlags_Stationary to require mouse being stationary when hovering a new item. Added style.HoverStationaryDelay (~0.15 sec). Once the mouse has been stationary once the state is preserved for same item. (#1485)
  • IsItemHovered: Added ImGuiHoveredFlags_ForTooltip as a shortcut for pulling flags from style.HoverFlagsForTooltipMouse or style.HoverFlagsForTooltipNav depending on active inputs. (#1485)
    • style.HoverFlagsForTooltipMouse defaults to ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort.
    • style.HoverFlagsForTooltipNav defaults to ImGuiHoveredFlags_NoSharedDelay | ImGuiHoveredFlags_DelayNormal.
  • Tooltips: Tweak default offset for non-drag and drop tooltips so underlying items isn't covered as much. (Match offset for drag and drop tooltips)
  • IsItemHovered: Tweaked default value of style.HoverDelayNormal from 0.30 to 0.40, Tweaked default value of style.HoverDelayShort from 0.10 to 0.15. (#1485)
  • IsItemHovered: Added ImGuiHoveredFlags_AllowWhenOverlappedByWindow to ignore window-overlap only. Option ImGuiHoveredFlags_AllowWhenOverlapped now expand into a combination of both _AllowWhenOverlappedByWindow + _AllowWhenOverlappedByItem, matching old behavior.
• Overlapping items: (#6512, #3909, #517)
  • Most item types should now work with SetNextItemAllowOverlap(). (#6512, #3909, #517)
  • Fixed first frame of an overlap highlighting underlying item if previous frame didn't hover anything.
  • IsItemHovered: Changed to return false when querying an item using AllowOverlap mode which is being overlapped. Added ImGuiHoveredFlags_AllowWhenOverlappedByItem to opt-out. (#6512, #3909, #517)
  • Selectable, TreeNode: When using ImGuiSelectableFlags_AllowOverlap/ImGuiTreeNodeFlags_AllowOverlap and holding item held, overlapping widgets won't appear as hovered. (#6512, #3909)
• IsWindowHovered: Added support for ImGuiHoveredFlags_Stationary.
• IsWindowHovered, IsItemHovered: Assert when passed any unsupported flags.
• Tables: Fixed a regression in 1.89.6 leading to the first column of tables with either ScrollX or ScrollY flags from being impossible to resize. (#6503)
• CollapsingHeader/TreeNode: Fixed text padding when using _Framed+_Leaf flags. (#6549) [@BobbyAnguelov]
• InputText: Fixed not returning true when buffer is cleared while using the ImGuiInputTextFlags_EscapeClearsAll flag. (#5688, #2620)
• InputText: Fixed a crash on deactivating a ReadOnly buffer. (#6570, #6292, #4714)
• InputText: ImGuiInputTextCallbackData::InsertChars() accept (NULL,NULL) range, in order to conform to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#6565, #6566, #3615)
• Combo: Made simple/legacy Combo() function not returns true when picking already selected item. This is consistent with other widgets. If you need something else, you can use BeginCombo(). (#1182)
• Clipper: Rework inner logic to allow functioning with a zero-clear constructor. This is order to facilitate usage for language bindings (e.g cimgui or dear_binding) where user may not be calling a constructor manually. (#5856)
• Drag and Drop: Apply default behavior of drag source not reporting itself as hovered at lower-level, so DragXXX, SliderXXX, InputXXX, Plot widgets are fulfilling it. (Behavior doesn't apply when ImGuiDragDropFlags_SourceNoDisableHover is set).
• Modals: In the case of nested modal, made sure that focused or appearing windows are moved below the lowest blocking modal (rather than the highest one). (#4317)
• GetKeyName(): Fixed assert with ImGuiMod_XXX values when IMGUI_DISABLE_OBSOLETE_KEYIO is set.
• Debug Tools: Added io.ConfigDebugIniSettings option to save .ini data with extra comments. Currently mainly for inspecting Docking .ini data, but makes saving slower.
• Demo: Added more developed Widgets->Tooltips section. (#1485)
• Backends: OpenGL3: Fixed support for glBindSampler() backup/restore on ES3. (#6375, #6508) [@jsm174]
• Backends: OpenGL3: Fixed erroneous use glGetIntegerv(GL_CONTEXT_PROFILE_MASK) on contexts lower than 3.2. (#6539, #6333) [@krumelmonster]
• Backends: Vulkan: Added optional support for VK_KHR_dynamic_rendering (Vulkan 1.3+) in the backend, for applications using it. User needs to set init_info->UseDynamicRendering = true and init_info->ColorAttachmentFormat. RenderPass becomes unused. (#5446, #5037) [@spnda, @cmarcelo]
• Backends: GLFW: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser+Emscripten. Matches similar 1.89.4 fix in SDL backend. (#6491)
• Examples: Win32+OpenGL3: Changed DefWindowProc() to DefWindowProcW() to match other examples
  and support the example app being compiled without UNICODE. (#6516, #5725, #5961, #5975) [@yenixing]

Changes from 1.89.6 to 1.89.7 related to the docking branch (multi-viewport and docking features):

• Viewports+Docking: Fixed extraneous viewport+platform-window recreation in various combination of showing or hiding windows, docking with/without split, undocking. While with some backends and without OS decorations, some extraneous window recreation were visibly not noticeable, they would typically become noticeable when enabling OS decorations on those windows (e.g. Windows title bar fade-in/animation).
• Viewports: Closing a viewport via OS...

Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4, v1.89.5. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

I have been stubbornly deferring tagging 1.90 for while because I wanted to include the range-select feature in it, but it's not done... But there are nearly 500 lines of changelog between 1.89 and 1.89.6.

Breaking Changes:

• Clipper: Commented out obsolete redirection constructor which was marked obsolete in 1.79:
  • ImGuiListClipper(int items_count, float items_height) --> Use ImGuiListClipper() + clipper.Begin().
• Clipper: Renamed ForceDisplayRangeByIndices() to IncludeRangeByIndices(), kept inline redirection function (introduced in 1.86 and rarely used). (#6424, #3841)
• Commented out obsolete/redirecting functions that were marked obsolete more than two years ago:
  • ListBoxHeader() -> use BeginListBox()
  • ListBoxFooter() -> use EndListBox()
  • Note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for refeence.
• Backends: SDL_Renderer: Renamed 'imgui_impl_sdlrenderer.h/cpp' to 'imgui_impl_sdlrenderer2.h/cpp',
  in order to accomodate for upcoming SDL3 and change in its SDL_Renderer API. (#6286)
• Backends: GLUT: Removed call to ImGui::NewFrame() from ImGui_ImplGLUT_NewFrame(). It needs to be called from the main app loop, like with every other backends. (#6337) [@GereonV]

Other Changes:

• Window: Fixed resizing from upper border when io.ConfigWindowsMoveFromTitleBarOnly is set. (#6390)
• Tables: Fixed a small miscalculation in TableHeader() leading to an empty tooltip showing when a sorting column has no visible name. (#6342) [@lukaasm]
• Tables: Fixed command merging when compiling with VS2013 (one array on stack was not initialized on VS2013. Unsure if due to a bug or UB/standard conformance). (#6377)
• InputText: Avoid setting io.WantTextInputNextFrame during the deactivation frame. (#6341) [@lukaasm]
• Drag, Sliders: if the format string doesn't contain any %, CTRL+Click to input text will use the default format specifier for the type. Allow display/input of raw value when using "enums" patterns (display label instead of value) + allow using when value is hidden. (#6405)
• Nav: Record/restore preferred position on each given axis after a movement on that axis, then score movement on the other axis using this as a bias. This allows going up and down between e.g. a large header spanning horizontal space and three-ways-columns, landing on the same column as before.
• Nav: Fixed navigation within tables/columns where item boundaries goes beyond columns limits, unclipped bounding boxes would interfere with other columns. (#2221) [@zzzyap, @ocornut]
• Nav: Fixed CTRL+Tab into a root window with only childs with _NavFlattened flags erroneously initializing default nav layer to menu layer.
• Menus: Fixed an issue when opening a menu hierarchy in a given menu-bar would allow opening another via simple hovering. (#3496, #4797)
• Fonts: Fixed crash when merging fonts and the first font has no valid glyph. (#6446) [@JaedanC]
• Fonts: Fixed crash when manually specifying an EllipsisChar that doesn't exist. (#6480)
• Misc: Added ImVec2 unary minus operator. (#6368) [@koostosh]
• Debug Tools: Debug Log: Fixed not parsing 0xXXXXXXXX values for geo-locating on mouse hover hover when the identifier is at the end of the line. (#5855)
• Debug Tools: Added io.ConfigDebugIgnoreFocusLoss option to disable io.AddFocusEvent(false) handling. May facilitate interactions with a debugger when focus loss leads to clearing inputs data. (#4388, #4921)
• Backends: Clear bits sets io.BackendFlags on backend Shutdown(). (#6334, #6335] [@GereonV]
  Potentially this would facilitate switching runtime backend mid-session.
• Backends: Win32: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
• Backends: OpenGL3: Restore front and back polygon mode separately when supported by context (Desktop 3.0, 3.1, or 3.2+ with compat bit). (#6333) [@GereonV]
• Backends: OpenGL3: Support for glBindSampler() backup/restore on ES3. (#6375) [@jsm174]
• Backends: SDL3: Fixed build on Emscripten/iOS/Android. (#6391) [@jo-codegirl]
• Backends: SDLRenderer3: Added SDL_Renderer for SDL3 backend. (#6286) [@Carcons, @ocornut]
• Examples: Added native Win32+OpenGL3 example. We don't recommend using this setup but we provide it for completeness. (#3218, #5170, #6086, #2772, #2600, #2359, #2022, #1553) [@learn-more]
• Examples: Vulkan: Use integrated GPU if nothing else is available. (#6359) [@kimidaisuki22]
• Examples: DX9, DX10, DX11: Queue framebuffer resize instead of processing in WM_SIZE, as some drivers tends to only cleanup after existing the native resize modal loop. (#6374)
• Examples: Added SDL3+SDL_Renderer example. (#6286)
• Examples: Updated all Visual Studio projects and batches to use /utf-8 argument.

Changes from 1.89.5 to 1.89.6 related to the docking branch (multi-viewport and docking features) include:

• Viewports: Fixed platform-side focus (e.g. Alt+Tab) from leading to accidental closure of Modal windows. Regression from 1.89.5. (#6357, #6299)
• Viewports: Fixed erroneous popup closure on closing a previous popup. (#6462, #6299)
• Viewports: Fixed loss of imgui-side focus when dragging a secondary viewport back in main viewport, due to platform-side handling changes. Regression from 1.89.5 (#6299)
• Viewports: Added void* ImGuiPlatformMonitor::PlatformHandle field (backend-dependant), for usage by user code.
• Backends: GLFW: Preserve monitor list when there are no monitor, may briefly happen when recovering from macOS sleeping mode. (#5683) [@Guistac]
• Backends: SDL2: Update monitor list when receiving a display event. (#6348) Note however that SDL2 currently doesn't have an event for a DPI/Scaling change, so monitor data won't be updated in this situation.
• Backends: SDL3: Update monitor list when receiving a display event. (#6348)

Changes from 1.89.5 to 1.89.6 related to the range-select branch: (aimed to finish, apply some api changes and merge in 1.90):

• RangeSelect/MultiSelect: (BREAKING) Renamed ImGuiMultiSelectData to ImGuiMultiSelectIO.
• RangeSelect/MultiSelect: Made SetNextItemSelectionData() optional to allow disjoint selection (e.g. with a CollapsingHeader between items).
• RangeSelect/MultiSelect: Enter can alter selection if current item is not selected.
• RangeSelect/MultiSelect: Removed DragDropActive/preserve_existing_selection logic which seems unused + comments.
• RangeSelect/MultiSelect: Demo tweak. Removed multi-scope from Advanced (too messy), made it a separate mini-demo

TL;DR

Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

All Changes:

• InputText: Reworked prev/next-word behavior to more closely match Visual Studio text editor. Include '.' as a delimiter and alter varying subtle behavior with how blanks and separators are treated when skipping words. (#6067) [@ajweeks]
• InputText: Fixed a tricky edge case, ensuring value is always written back on the frame where IsItemDeactivated() returns true, in order to allow usage without user retaining underlying data. While we don't really want to encourage user not retaining underlying data, in the absence of a "late commit" behavior/flag we understand it may be desirable to take advantage of this trick. (#4714)
• Drag, Sliders: Fixed parsing of text input when '+' or '#' format flags are used in the format string. (#6259) [@idbrii]
• Nav: Made Ctrl+Tab/Ctrl+Shift+Tab windowing register ownership to held modifier so it doesn't interfere with other code when remapping those actions. (#4828, #3255, #5641)
• Nav: Made PageUp/PageDown/Home/End navigation also scroll parent windows when necessary to make the target location fully visible (same as e.g. arrow keys).
• ColorEdit: Fixed shading of S/V triangle in Hue Wheel mode. (#5200, #6254) [@jamesthomasgriffin]
• TabBar: Tab-bars with ImGuiTabBarFlags_FittingPolicyScroll can be scrolled with horizontal mouse-wheel (or Shift + WheelY). (#2702)
• Rendering: Using adaptive tessellation for RadioButton, ColorEdit preview circles, Windows Close and Collapse Buttons.
• ButtonBehavior: Fixed an edge case where changing widget type/behavior while active and using same id could lead to an assert. (#6304)
• Misc: Fixed ImVec2 operator[] violating aliasing rules causing issue with Intel C++ compiler. (#6272) [@BayesBug]
• IO: Input queue trickling adjustment for touch screens. Fixes single-tapping to move simulated mouse and immediately click on a widget that is using the ImGuiButtonFlags_AllowItemOverlap policy. (#2702, #4921)
  • This only works if the backend can distinguish TouchScreen vs Mouse. See 'Demo->Tools->Metrics->Inputs->Mouse Source' to verify.
  • Fixed tapping on BeginTabItem() on a touch-screen. (#2702)
  • Fixed tapping on CollapsingHeader() with a close button on a touch-screen.
  • Fixed tapping on TreeNode() using ImGuiTreeNodeFlags_AllowItemOverlap on a touch-screen.
  • Fixed tapping on Selectable() using ImGuiSelectableFlags_AllowItemOverlap on a touch-screen.
  • Fixed tapping on TableHeader() on a touch-screen.
• IO: Added io.AddMouseSourceEvent() and ImGuiMouseSource enum. This is to allow backend to specify actual event source between Mouse/TouchScreen/Pen. (#2702, #2334, #2372, #3453, #5693)
• IO: Fixed support for calling io.AddXXXX functions from inactive context (wrongly advertised as supported in 1.89.4). (#6199, #6256, #5856) [@cfillion]
• Backends: OpenGL3: Fixed GL loader crash when GL_VERSION returns NULL. (#6154, #4445, #3530)
• Backends: OpenGL3: Properly restoring "no shader program bound" if it was the case prior to running the rendering function. (#6267, #6220, #6224) [@BrunoLevy]
• Backends: Win32: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen/Pen. (#2334, #2702)
• Backends: SDL2/SDL3: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen. This is relying on SDL passing SDL_TOUCH_MOUSEID in the event's 'which' field. (#2334, #2702)
• Backends: SDL2/SDL3: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they actually block text input input and don't only pertain to IME. It's unclear exactly what their relation is to other IME function such as SDL_SetTextInputRect(). (#6306, #6071, #1953)
• Backends: GLFW: Added support on Win32 only for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen/Pen. (#2334, #2702)
• Backends: GLFW: Fixed key modifiers handling on secondary viewports. (#6248, #6034) [@aiekick]
• Backends: Android: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen/Pen. (#6315) [@PathogenDavid]
• Backends: OSX: Added support for io.AddMouseSourceEvent() to discriminate Mouse/Pen. (#6314) [@PathogenDavid]
• Backends: WebGPU: Align buffers. Use WGSL shaders instead of SPIR-V. Add gamma uniform. (#6188) [@eliemichel]
• Backends: WebGPU: Reorganized to store data in io.BackendRendererUserData like other backends.
• Examples: Vulkan: Fixed validation errors with newer VulkanSDK by explicitly querying and enabling "VK_KHR_get_physical_device_properties2", "VK_KHR_portability_enumeration", and
  VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR. (#6109, #6172, #6101)
• Examples: Windows: Added misc/debuggers/imgui.natstepfilter file to all Visual Studio projects, now that VS 2022 17.6 Preview 2 support adding Debug Step Filter spec files into projects.
• Examples: SDL3: Updated for latest WIP SDL3 branch. (#6243)
• TestSuite: Added variety of new regression tests and improved/amended existing ones
  in imgui_test_engine/ repository. [@PathogenDavid, @ocornut]

Changes from 1.89.4 to 1.89.5 related to the docking branch (multi-viewport and docking features) include:

• Viewports: Setting focus from Platform/OS (e.g. via decoration, or Alt-Tab) sets corresponding focus at Dear ImGui level (generally last focused window in the viewport). (#6299)
• Docking: Fixed using GetItemXXX() or IsItemXXX() functions after a DockSpace() call. (#6217)
• Backends: GLFW: Fixed key modifiers handling on secondary viewports. (#6248, #6034) [@aiekick]
• Backends: GLFW: Fixed Emscripten erroneously enabling multi-viewport support, leading to assert. (#5683)
• Backends: SDL2/SDL3: Fixed IME text input rectangle position with viewports. (#6071, #1953)
• Backends: SDL3: Fixed for compilation with multi-viewports. (#6255) [@P3RK4N]

Changes from 1.89.4 to 1.89.5 related to the range-select branch: (aimed to finish, apply some api changes and merge in 1.90):

• RangeSelect/MultiSelect: Fixed 'Enter' to never alter selection (unlike Space).
• RangeSelect/MultiSelect: Fixed needing to set RangeSrcPassedBy when not using clipper.
• RangeSelect/MultiSelect: Added ImGuiMultiSelectFlags_ClearOnClickWindowVoid.
• RangeSelect/MultiSelect: Added ImGuiMultiSelectFlags_ClearOnEscape.

TL;DR

• Nav: Tab key goes through every items (when keyboard navigation is active).
• Nav: Enter key works to activate most items (when keyboard navigation is active).
• Added return value to BeginTooltip().
• Examples: Activated keyboard and gamepad navigation by default in all examples.
• Various other fixes related to: Nav, Tables, Drag and Drop, InputText.
• Various improvements to Win32, SDL2, SDL3, GLFW backends.
• Added a Debug Tools to facilitate testing user-code testing Begin/BeginChild return value.

Changes

This is a followup to v1.89, v1.89.1, v1.89.2 and v1.89.3. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

Breaking Changes:

• Renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop(). Kept inline redirection functions (will obsolete).
• Moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h. Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA, it has been frequently requested by people to use our own. We had an opt-in define which was previously fulfilled by imgui_internal.h. It is now fulfilled by imgui.h. (#6164, #6137, #5966, #2832)
  • OK: #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui.h" / #include "imgui_internal.h"
  • Error: #include "imgui.h" / #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui_internal.h"
  • Added a dedicated compile-time check message to help diagnose this.
• Tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will currently always return true, but further changes down the line may change this, best to clarify API sooner. Updated demo code accordingly.
• Commented out redirecting enums/functions names that were marked obsolete two years ago:
  • ImGuiSliderFlags_ClampOnInput -> use ImGuiSliderFlags_AlwaysClamp
  • ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite
  • ImDrawList::AddBezierCurve() -> use ImDrawList::AddBezierCubic()
  • ImDrawList::PathBezierCurveTo() -> use ImDrawList::PathBezierCubicCurveTo()

Other Changes:

• Nav: Tabbing now cycles through all items when ImGuiConfigFlags_NavEnableKeyboard is set. (#3092, #5759, #787)
  While this was generally desired and requested by many, note that its addition means that some types of UI may become more fastidious to use TAB key with, if the navigation cursor cycles through too many items. You can mark items items as not tab-spottable:
  • Public API: PushTabStop(false) / PopTabStop().
  • Internal: PushItemFlag(ImGuiItemFlags_NoTabStop, true);.
  • Internal: Directly pass ImGuiItemFlags_NoTabStop to ItemAdd() for custom widgets.
• Nav: Tabbing/Shift-Tabbing can more reliably be used to step out of an item that is not tab-stoppable. (#3092, #5759, #787)
• Nav: Made Enter key submit the same type of Activation event as Space key, allowing to press buttons with Enter. (#5606)
  (Enter emulates a "prefer text input" activation vs. Space emulates a "prefer tweak" activation which is to closer to gamepad controls).
• Nav: Fixed an issue with Gamepad navigation when the movement lead to a scroll and frame time > repeat rate. Triggering a new move request on the same frame as a move result lead to an incorrect calculation and loss of navigation id. (#6171)
• Nav: Fixed SetItemDefaultFocus() from not scrolling when item is partially visible. (#2814, #2812) [@DomGries]
• Tables: Fixed an issue where user's Y cursor movement within a hidden column would have side-effects.
• IO: Lifted constraint to call io.AddEventXXX functions from current context. (#4921, #5856, #6199)
• InputText: Fixed not being able to use CTRL+Tab while an InputText() using Tab for completion or text data is active (regression from 1.89).
• Drag and Drop: Fixed handling of overlapping targets when smaller one is submitted before and can accept the same data type. (#6183).
• Drag and Drop: Clear drag and drop state as soon as delivery is accepted in order to avoid interferences. (#5817, #6183) [@DimaKoltun]
• Debug Tools: Added io.ConfigDebugBeginReturnValueOnce / io.ConfigDebugBeginReturnValueLoop options to simulate Begin/BeginChild returning false to facilitate debugging user behavior.
• Demo: Updated to test return value of BeginTooltip().
• Backends: OpenGL3: Fixed restoration of a potentially deleted OpenGL program. If an active program was pending deletion, attempting to restore it would error. (#6220, #6224) [@Cyphall]
• Backends: Win32: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse positions over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
• Backends: SDL2, SDL3: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644) [@adamkewley]
• Backends: GLFW: Avoid using glfwGetError() and glfwGetGamepadState() on Emscripten, which recently updated its GLFW emulation layer to GLFW 3.3 without supporting those. (#6240)
• Examples: Android: Fixed example build for Gradle 8. (#6229, #6227) [@duddel]
• Examples: Updated all examples application to enable ImGuiConfigFlags_NavEnableKeyboard and ImGuiConfigFlags_NavEnableGamepad by default. (#787)
• Internals: Misc tweaks to facilitate applying an explicit-context patch. (#5856) [@Dragnalith]

TL;DR

• Renamed SDL2 backend files (+ Added experimental SDL3 backend).
• Fixed wrapping text regression from previous versions.
• Added SeparatorText().
• Lifted limit on table columns count.
• Fixed to horizontal scrolling wheel in many backends.
• More Emscripten examples + fixes for Emscripten.
• Many other tweaks/fixes.

Changes

This is a followup to v1.89, v1.89.1 and v1.89.2. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

Breaking Changes:

• Backends+Examples: SDL2: renamed all unnumbered references to "sdl" to "sdl2". This is in prevision for the future release of SDL3 and its associated backend. (#6146)
  • imgui_impl_sdl.cpp -> imgui_impl_sdl2.cpp
  • imgui_impl_sdl.h -> imgui_impl_sdl2.h
  • example_sdl_xxxx/ -> example_sdl2_xxxx/ (folders and projects)

Other Changes:

• SeparatorText(): Added SeparatorText() widget. (#1643) [@phed, @ocornut]
  • Added to style: float SeparatorTextBorderSize.
  • Added to style: ImVec2 SeparatorTextAlign, ImVec2 SeparatorTextPadding.
• Tables: Raised max Columns count from 64 to 512. The previous limit was due to using 64-bit integers but we moved to bits-array and tweaked the system enough to ensure no performance loss. (#6094, #5305, #4876, #3572)
• Tables: Solved an ID conflict issue with multiple-instances of a same table, due to how unique table instance id was generated. (#6140) [@ocornut, @rodrigorc]
• Inputs, Scrolling: Made horizontal scroll wheel and horizontal scroll direction consistent across backends/os. (#4019, #6096, #1463) [@PathogenDavid, @ocornut, @rokups]
  • Clarified that 'wheel_y > 0.0f' scrolls Up, 'wheel_y > 0.0f' scrolls Down.
  • Clarified that 'wheel_x > 0.0f' scrolls Left, 'wheel_x > 0.0f' scrolls Right.
  • Backends: Fixed horizontal scroll direction for Win32 and SDL backends. (#4019)
  • Shift+WheelY support on non-OSX machines was already correct. (#2424, #1463) (whereas on OSX machines Shift+WheelY turns into WheelX at the OS level).
  • If you use a custom backend, you should verify horizontal wheel direction.
    • Axises are flipped by OSX for mouse & touch-pad when 'Natural Scrolling' is on.
    • Axises are flipped by Windows for touch-pad when 'Settings->Touchpad->Down motion scrolls up' is on.
    • You can use Demo->Tools->Debug Log->IO to visualize values submitted to Dear ImGui.
  • Known issues remaining with Emscripten:
    • The magnitude of wheeling values on Emscripten was improved but isn't perfect. (#6096)
    • When running the Emscripten app on a Mac with a mouse, SHIFT+WheelY doesn't turn into WheelX. This is because we don't know that we are running on Mac and apply our own Shift+swapping on top of OSX' own swapping, so wheel axises are swapped twice. Emscripten apps may need to find a way to detect this and set io.ConfigMacOSXBehaviors manually (if you know a way let us know!), or offer the "OSX-style behavior" option to their user.
• Window: Avoid rendering shapes for hidden resize grips.
• Text: Fixed layouting of wrapped-text block skipping successive empty lines, regression from the fix in 1.89.2. (#5720, #5919)
• Text: Fixed clipping of single-character "..." ellipsis (U+2026 or U+0085) when font is scaled. Scaling wasn't taken into account, leading to ellipsis character straying slightly out of its expected boundaries. (#2775)
• Text: Tweaked rendering of three-dots "..." ellipsis variant. (#2775, #4269)
• InputText: Added support for Ctrl+Delete to delete up to end-of-word. (Not adding Super+Delete to delete to up to end-of-line on OSX, as OSX doesn't have it) (#6067) [@ajweeks]
• InputText: On OSX, inhibit usage of Alt key to toggle menu when active (used for work skip).
• Menus: Fixed layout of MenuItem()/BeginMenu() when label contains a '\n'. (#6116) [@imkcy9]
• ColorEdit, ColorPicker: Fixed hue/saturation preservation logic from interfering with the displayed value (but not stored value) of others widgets instances. (#6155)
• PlotHistogram, PlotLines: Passing negative sizes honor alignment like other widgets.
• Combo: Allow SetNextWindowSize() to alter combo popup size. (#6130)
• Fonts: Assert that in each GlyphRanges[] pairs first is <= second.
• ImDrawList: Added missing early-out in AddPolyline() and AddConvexPolyFilled() when color alpha is zero.
• Misc: Most text functions treat "%s" as a shortcut to no-formatting. (#3466)
• Misc: Tolerate zero delta-time under Emscripten as backends are imprecise in their values for io.DeltaTime, and browser features such as privacy.resistFingerprinting=true can exacerbate that. (#6114, #3644)
• Backends: OSX: Fixed scroll/wheel scaling for devices emitting events with hasPreciseScrollingDeltas==false (e.g. non-Apple mices).
• Backends: Win32: flipping WM_MOUSEHWHEEL horizontal value to match other backends and offer consistent horizontal scrolling direction. (#4019)
• Backends: SDL2: flipping SDL_MOUSEWHEEL horizontal value to match other backends and offer consistent horizontal scrolling direction. (#4019)
• Backends: SDL2: Removed SDL_MOUSEWHEEL value clamping. (#4019, #6096, #6081)
• Backends: SDL2: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling as reported by SDL. (#4019, #6096)
• Backends: SDL2: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (already fixed in SDL latest trunk). (#6113)
• Backends: SDL2: Implement IME handler to call SDL_SetTextInputRect()/SDL_StartTextInput(). It will only works with SDL 2.0.18+ if your code calls 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1")' prior to calling SDL_CreateWindow(). Updated all examples accordingly. (#6071, #1953)
• Backends: SDL3: Added experimental imgui_impl_sdl3.cpp backend. SDL 3.0.0 has not yet been released, so it is possible that its specs/api will change before release. This backend is provided as a convenience for early adopters etc. We don't recommend
  switching to SDL3 before it is released. (#6146) [@dovker, @ocornut]
• Backends: GLFW: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096) [@ocornut, @wolfpld, @tolopolarity]
• Backends: GLFW: Added ImGui_ImplGlfw_SetCallbacksChainForAllWindows() to instruct backend to chain callbacks even for secondary viewports/windows. User callbacks may need to test the 'window' parameter. (#6142)
• Backends: OpenGL3: Fixed GL loader compatibility with 2.x profiles. (#6154, #4445, #3530) [@grauw]
• Backends: WebGPU: Fixed building for latest WebGPU specs (remove implicit layout generation). (#6117, #4116, #3632) [@tonygrue, @bfierz]
• Examples: refactored SDL2+GL and GLFW+GL examples to compile with Emscripten. (#2492, #2494, #3699, #3705) [@ocornut, @nicolasnoble] The dedicated example_emscripten_opengl3/ has been removed.
• Examples: Added SDL3+GL experimental example. (#6146)
• Examples: Win32: Fixed examples using RegisterClassW() since 1.89 to also call DefWindowProcW() instead of DefWindowProc() so that title text are correctly converted when application is compiled without /DUNICODE. (#5725, #5961, #5975) [@markreidvfx]
• Examples: SDL2+SDL_Renderer: Added call to SDL_RenderSetScale() to fix display on a Retina display (albeit lower-res as our other unmodified examples). (#6121, #6065, #5931).

Changes from 1.89.2 to 1.89.3 related to the docking branch (multi-viewport and docking features) include:

• Backends: GLFW: Handle unsupported glfwGetVideoMode() for Emscripten. (#6096)

Changes

This is a followup to v1.89 and v1.89.1. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

All Changes:

• Tables, Nav, Scrolling: fixed scrolling functions and focus tracking with frozen rows and frozen columns. Windows now have a better understanding of outer/inner decoration sizes, which should later lead us toward more flexible uses of menu/status bars. (#5143, #3692)
• Tables, Nav: frozen columns are not part of menu layer and can be crossed over. (#5143, #3692)
• Tables, Columns: fixed cases where empty columns may lead to empty ImDrawCmd. (#4857, #5937)
• Tables: fixed matching width of synchronized tables (multiple tables with same id) when only some instances have a vertical scrollbar and not all. (#5920)
• Fixed cases where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with zero triangles, which would makes the render loop of some backends assert (e.g. Metal with debugging, Allegro). (#4857, #5937)
• Inputs, IO: reworked ImGuiMod_Shortcut to redirect to Ctrl/Super at runtime instead of compile-time, being consistent with our support for io.ConfigMacOSXBehaviors and making it easier for bindings generators to process that value. (#5923, #456)
• Inputs, Scrolling: better selection of scrolling window when hovering nested windows and when backend/OS is emitting dual-axis wheeling inputs (typically touch pads on macOS). We now select a primary axis based on recent events, and select a target window based on it. We expect this behavior to be further improved/tweaked. (#3795, #4559) [@ocornut, @folays]
• InputText: fixed cursor navigation when pressing Up Arrow on the last character of a multi-line buffer which doesn't end with a carriage return. (#6000)
• Text: fixed layouting of wrapped-text block when the last source line is above the clipping region. Regression added in 1.89. (#5720, #5919)
• Misc: added GetItemID() in public API. It is not often expected that you would use this, but it is useful for Shortcut() and upcoming owner-aware input functions which wants to be implemented with public API.
• Fonts: imgui_freetype: fixed a packing issue which in some occurrences would prevent large amount of glyphs from being packed correctly. (#5788, #5829)
• Fonts: added a void* UserData field in ImFontAtlas, as a convenience for use by applications using multiple font atlases.
• Demo: simplified "Inputs" section, moved contents to Metrics->Inputs.
• Debug Tools: Metrics: added "Inputs" section, moved from Demo for consistency.
• Misc: fixed parameters to IMGUI_DEBUG_LOG() not being dead-stripped when building with IMGUI_DISABLE_DEBUG_TOOLS is used. (#5901) [@Teselka]
• Misc: fixed compile-time detection of SSE features on MSVC 32-bits builds. (#5943) [@TheMostDiligent]
• Examples: DirectX10, DirectX11: try WARP software driver if hardware driver is not available. (#5924, #5562)
• Backends: GLFW: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), which could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they are faulty in this specific situation. (#6034)
• Backends: Allegro5: restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5. (#5937) [@Espyo]
• Backends: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored as we were using an immutable sampler. (#5502, #6001, #914) [@martin-ejdestig, @rytisss]

Changes from 1.89.1 to 1.89.2 related to the docking branch (multi-viewport and docking features) include:

• Docking: Internals: fixed DockBuilderCopyDockSpace() crashing when windows not in the remapping list are docked on the left or top side of a split. (#6035)
• Docking: fixed DockSpace() with ImGuiDockNodeFlags_KeepAliveOnly marking current window as written to, even if it doesn't technically submit an item. This allow using KeepAliveOnly from any window location. (#6037)
• Backends: OSX: fixed typo in ImGui_ImplOSX_GetWindowSize that would cause issues when resizing from OS decorations, if they are enabled on secondary viewports. (#6009) [@sivu]
• Backends: Metal: fixed secondary viewport rendering. (#6015) [@dmirty-kuzmenko]

Changes

This is mostly a couple of changes to amend the release of v1.89:

• Scrolling, Focus: fixed SetKeyboardFocusHere()/SetItemDefaultFocus() during a window-appearing frame (and associated lower-level functions e.g. ScrollToRectEx()) from not centering item. (#5902)
• Inputs: fixed moving a window or drag and dropping from preventing input-owner-unaware code from accessing keys. (#5888, #4921, #456)
• Inputs: fixed moving a window or drag and dropping from capturing mods. (#5888, #4921, #456)
• Layout: fixed End()/EndChild() incorrectly asserting if users manipulates cursor position inside a collapsed/culled window and IMGUI_DISABLE_OBSOLETE_FUNCTIONS is enabled. (#5548, #5911)
• Combo: fixed selected item (marked with SetItemDefaultFocus()) from not being centered when the combo window initially appears. (#5902).
• ColorEdit: fixed label overlapping when using style.ColorButtonPosition == ImGuiDir_Left to move the color button on the left side (regression introduced in 1.88 WIP 2022/02/28). (#5912)
• Drag and Drop: fixed GetDragDropPayload() returning a non-NULL value if a drag source is active but a payload hasn't been submitted yet. This is convenient to detect new payload from within a drag source handler. (#5910, #143)
• Backends: GLFW: cancel out errors emitted by glfwGetKeyName() when a name is missing. (#5908)
• Backends: WebGPU: fixed validation error with default depth buffer settings. (#5869, #5914) [@kdchambers]

Changes from 1.89 to 1.89,1 related to the docking branch (multi-viewport and docking features) include:

• Viewport: Fixed collapsed windows setting ImGuiViewportFlags_NoRendererClear without making title bar color opaque, leading to potential texture/fb garbage being visible. Right now as we don't fully support transparent viewports (#2766), so we turn that TitleBgCollapsed color opaque just like we do for WindowBG on uncollapsed windows.

New secret exciting stuff!

Since 1.89 we semi-sneakily soft launched two new entire projects!

TL;DR;

Some arbitrary highlights among the 90+ changes:

• Debug Tools: Hovering 0xXXXXXXX ids in Debug Log and Metrics can now visually locate the item. (#5855)
• Popups & Modals: fixed nested Begin() inside a popup being erroneously input-inhibited.
• IO: Mitigate scrolling issues on system sending dual-axis wheel data simultaneously (more fixes coming later).
• IsItemHovered: added ImGuiHoveredFlags_DelayNormal and ImGuiHoveredFlags_DelayShort for delayed hover test (work on items that have no persistent identifier e.g. Text items).
• InputText: added ImGuiInputTextFlags_EscapeClearsAll and io.ConfigInputTextEnterKeepActive. Added Shift+Click style selection. Improvements for numerical inputs for IME mode sending full-width characters. Other fixes.
• Menus: various fixes for menu item inside non-popup root windows. Fixes for keyboard/gamepad navigations.
• TabBar: fixes occasional freezes when feeding non-rounded tab widths.
• Backends: Many fixes: freezing IME on Win32, fix for SDL 2.0.22 auto-capture and drag and drop issues with multi-viewports, fixes corruptions issues with OpenGL and multi-viewports on buggy Intel GPU drivers, OSX support for C++ apps etc.
• Obsoleted variety of old symbols, with backward-compatible redirection for newly obsoleted stuff.
• Internals: added wip internal APIs to allow handling input/shorting routing and key ownership. Things will be moved into public APIs over time, including a Shortcut() function that magically handle input routing.
• And many more things...

See Wiki Page: Debug Tools

Breaking Changes

(Suggestion: once in a while, add #define IMGUI_DISABLE_OBSOLETE_FUNCTIONS in your imconfig.h file to make sure you are not using to-be-obsoleted symbols.)

• Layout: Obsoleted using SetCursorPos() / SetCursorScreenPos() to extend parent window/cell boundaries. (#5548)
  This relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item.
  • Previously this would make the window content size ~200x200:
    Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End()
  • Instead, please submit an item:
    Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End()
  • Or simpler alternative:
    Begin(...) + Dummy(ImVec2(200,200)) + End();
  • Content size is now only extended when submitting an item.
    • With #define IMGUI_DISABLE_OBSOLETE_FUNCTIONS this will now be detected and assert.
    • Without #define IMGUI_DISABLE_OBSOLETE_FUNCTIONS this will silently be fixed until we obsolete it.
    • This incorrect pattern has been mentioned or suggested in: #4510, #3355, #1760, #1490, #4152, #150, threads have been amended to refer to this issue.
• Renamed and merged keyboard modifiers key enums and flags into a same set: (#4921, #456)
  • ImGuiKey_ModCtrl and ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl
  • ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift
  • ImGuiKey_ModAlt and ImGuiModFlags_Alt -> ImGuiMod_Alt
  • ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super
    Kept inline redirection enums (will obsolete). This change simplifies a few things, reduces confusion, and will facilitate upcoming shortcut/input ownership apis.
  • (The ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends. The ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api, only by third-party extensions. They were however subject to a recent rename ImGuiKeyModFlags_XXX -> ImGuiModFlags_XXX and we are exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway.)
• Removed io.NavInputs[] and ImGuiNavInput enum that were used to feed gamepad inputs. Basically 1.87 already obsoleted them from the backend's point of view, but internally our navigation code still used this array and enum, so they were still present. Not anymore! (#4921, #4858, #787, #1599, #323)
  Transition guide:
  • Official backends from 1.87:
    • no issue.
  • Official backends from 1.60 to 1.86:
    • will compile and convert legacy gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating!
  • Custom backends not writing to io.NavInputs[] (no gamepad support)
    • no issue.
  • Custom backends writing to io.NavInputs[]:
    • will compile and convert legacy gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing!
  • TL;DR: Backends should call io.AddKeyEvent() / io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[]. The ImGuiNavInput enum was essentially 1.60's attempt to combine keyboard and gamepad inputs with named semantic, but the additional indirection and copy added complexity and got in the way of other incoming work. User's code (other than backends) should not be affected, unless you have custom widgets intercepting navigation events via the named enums (in which case you can upgrade your code).
• DragInt(), SliderInt(): Removed runtime patching of invalid "%f"/"%.0f" types of format strings. This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details.
• Changed signature of ImageButton() function: (#5533, #4471, #2464, #1390)
  • Added const char* str_id parameter + removed int frame_padding = -1 parameter.
  • Old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
    • used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values.
    • had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer.
  • New signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
    • requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier.
    • always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this.
  • As always we are keeping a redirection function available (will obsolete later).
• Removed the bizarre legacy default argument for TreePush(const void* ptr = NULL). Must always pass a pointer value explicitly, NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr); If you used TreePush() replace with TreePush((void*)NULL); (#1057)
• Commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.79 (August 2020): (#3361)
  • DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4()
  • SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4()
    • For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.
  • BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags)
  • OpenPopupContextItem() (briefly existed from 1.77 to 1.79) -> use OpenPopupOnItemClick()
• Removed support for 1.42-era IMGUI_DISABLE_INCLUDE_IMCONFIG_H / IMGUI_INCLUDE_IMCONFIG_H. They only made sense before we could use IMGUI_USER_CONFIG. (#255)

Other Changes

• Popups & Modals: fixed nested Begin() inside a popup being erroneously input-inhibited. While it is unusual, you can nest a Begin() inside a popup or mo...

TL;DR;

This is a general "many things" release. Initially I was expecting 1.88 to include new features for input ownership and input routing but it's not ready and we haven't had a release for a while. Among the 80+ changes, some that may interest more people:

• Various fixes related to the 1.87 input io/queue changes.
• Debug: Added of a "Dear ImGui Debug Log" window facilitating looking into common issues (e.g. focus change, popup closure, active id being stolen, etc.).
• Debug: Added a "UTF-8 Encoding Viewer" in Metrics and DebugTextEncoding() function to help validating UTF-8 code since many users have issues with UTF-8 encoding and C++ makes things difficult.
• Sliders: Clicking within the grab/knob of a non-Drag Slider width doesn't alter current value.
• InputText: Fixed undo-state corruptions when altering in-buffers in user callback and in other cases.
• Tables: Fixed a rather frequent draw-call merging issues (some tables created an unnecessary extra draw-call).
• Fixed subtle or rare nav and focus issues.
• Many backends fixes (including tentative fixes for frequent OpenGL issues on Windows in multi-viewport mode).
• Various Docking and Multi-viewport fixes.

Some of the debug tools

Breaking Changes

(Suggestion: once in a while, add #define IMGUI_DISABLE_OBSOLETE_FUNCTIONS in your imconfig.h file to make sure you are not using to-be-obsoleted symbols.)

• Renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS` for correctness. Kept support for old define (will obsolete).
• Renamed CaptureMouseFromApp() and CaptureKeyboardFromApp() to SetNextFrameWantCaptureMouse() and SetNextFrameWantCaptureKeyboard() to clarify purpose, old name was too misleading. Kept inline redirection functions (will obsolete).
• Renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). (This was never used in public API functions but technically present in imgui.h and ImGuiIO).
• Backends: OSX: Removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. Examples that are using the OSX backend have removed all the now-unnecessary calls to ImGui_ImplOSX_HandleEvent(), applications can do as well. [@stuartcarnie] (#4821)
• Internals: calling ButtonBehavior() without calling ItemAdd() now requires a KeepAliveID() call. This is because the KeepAliveID() call was moved from GetID() to ItemAdd(). (#5181)

Other Changes

• IO: Fixed backward-compatibility regression introduced in 1.87: (#4921, #4858)
  • Direct accesses to io.KeysDown[] with legacy indices didn't work (with new backends).
  • Direct accesses to io.KeysDown[GetKeyIndex(XXX)] would access invalid data (with old/new backends).
  • Calling IsKeyDown() didn't have those problems, and is recommended as io.KeysDown[] is obsolete.
• IO: Fixed input queue trickling of interleaved keys/chars events (which are frequent especially when holding down a key as OS submits chars repeat events) delaying key presses and mouse movements. In particular, using the input system for fast game-like actions (e.g. WASD camera move) would typically have been impacted, as well as holding a key while dragging mouse. Constraints have been lifted and are now only happening when e.g. an InputText() widget is active. (#4921, #4858)
  • Note that even thought you shouldn't need to disable io.ConfigInputTrickleEventQueue, you can technically dynamically change its setting based on the context (e.g. disable only when hovering or interacting with a game/3D view).
• IO: Fixed input queue trickling of mouse wheel events: multiple wheel events are merged, while a mouse pos followed by a mouse wheel are now trickled. (#4921, #4821)
• IO: Added io.SetAppAcceptingEvents() to set a master flag for accepting key/mouse/characters events (default to true). Useful if you have native dialog boxes that are interrupting your application loop/refresh, and you want to disable events being queued while your app is frozen.
• Windows: Fixed first-time windows appearing in negative coordinates from being initialized with a wrong size. This would most often be noticeable in multi-viewport mode (docking branch) when spawning a window in a monitor with negative coordinates. (#5215, #3414) [@DimaKoltun]
• Clipper: Fixed a regression in 1.86 when not calling clipper.End() and late destructing the clipper instance. High-level languages (Lua,Rust etc.) would typically be affected. (#4822)
• Layout: Fixed mixing up SameLine() and SetCursorPos() together from creating situations where line height would be emitted from the wrong location (e.g. ItemA+SameLine()+SetCursorPos()+ItemB' would emit ItemA worth of height from the position of ItemB, which is not necessarily aligned with ItemA).
• Sliders: An initial click within the knob/grab doesn't shift its position. (#1946, #5328)
• Sliders, Drags: Fixed dragging when using hexadecimal display format string. (#5165, #3133)
• Sliders, Drags: Fixed manual input when using hexadecimal display format string. (#5165, #3133)
• InputScalar: Fixed manual input when using %03d style width in display format string. (#5165, #3133)
• InputScalar: Automatically allow hexadecimal input when format is %X (without extra flag).
• InputScalar: Automatically allow scientific input when format is float/double (without extra flag).
• Nav: Fixed nav movement in a scope with only one disabled item from focusing the disabled item. (#5189)
• Nav: Fixed issues with nav request being transferred to another window when calling SetKeyboardFocusHere() and simultaneous changing window focus. (#4449)
• Nav: Changed SetKeyboardFocusHere() to not behave if a drag or window moving is in progress.
• Nav: Fixed inability to cancel nav in modal popups. (#5400) [@rokups]
• IsItemHovered(): added ImGuiHoveredFlags_NoNavOverride to disable the behavior where the return value is overridden by focus when gamepad/keyboard navigation is active.
• InputText: Fixed pressing Tab emitting two tabs characters because of dual Keys/Chars events being trickled with the new input queue (happened on some backends only). (#2467, #1336)
• InputText: Fixed a one-frame display glitch where pressing Escape to revert after a deletion would lead to small garbage being displayed for one frame. Curiously a rather old bug! (#3008)
• InputText: Fixed an undo-state corruption issue when editing main buffer before reactivating item. (#4947)
• InputText: Fixed an undo-state corruption issue when editing in-flight buffer in user callback. (#4947, #4949] [@JoshuaWebb]
• Tables: Fixed incorrect border height used for logic when resizing one of several synchronized instance of a same table ID, when instances have a different height. (#3955).
• Tables: Fixed incorrect auto-fit of parent windows when using non-resizable weighted columns. (#5276)
• Tables: Fixed draw-call merging of last column. Depending on some unrelated settings (e.g. BorderH) merging drawcall of the last column didn't always work (regression since 1.87). (#4843, #4844) [@rokups]
• Inputs: Fixed IsMouseClicked() repeat mode rate being half of keyboard repeat rate.
• ColorEdit: Fixed text baseline alignment after a SameLine() after a ColorEdit() with visible label.
• TabBar: BeginTabItem() now reacts to SetNextItemWidth(). (#5262)
• TabBar: Tweak shrinking policy so that while resizing tabs that don't need shrinking keep their initial width more precisely (without the occasional +1 worth of width).
• Menus: Adjusted BeginMenu() closing logic so hovering void or non-MenuItem() in parent window always lead to menu closure. Fixes using items that are not MenuItem() or BeginItem() at the root level of a popup with a child menu opened.
• Menus: Menus emitted from th...
