   and API updates have been a little more frequent lately. They are documented below and in imgui.cpp and should not affect all users.
 - Please report any issue!
 
+-----------------------------------------------------------------------
+ VERSION 1.91.0 (Released 2024-07-30)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.0
+
+Breaking changes:
+
+- IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness.
+    - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data);
+    - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);
+  It is expected that for a vast majority of users this is automatically set by core
+  library and/or platform backend so it won't have any effect.
+- Obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (#7838)
+  You should never need those functions! You can do everything in less a confusing manner by only
+  using GetCursorScreenPos() and GetContentRegionAvail(). Also always consider that if you are using
+  GetWindowPos() and GetCursorPos() you may also be making things unnecessarily complicated.
+  I repeat: You can do everything with GetCursorScreenPos() and GetContentRegionAvail()!
+   - GetWindowContentRegionMax().x - GetCursorPos().x              -->  GetContentRegionAvail().x
+   - GetWindowContentRegionMax().x + GetWindowPos().x              -->  GetCursorScreenPos().x + GetContentRegionAvail().x              // when called from left edge of window
+   - GetContentRegionMax()                                         -->  GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates
+   - GetWindowContentRegionMax().x - GetWindowContentRegionMin().x -->  GetContentRegionAvail()                                         // when called from left edge of window
+- Item flag changes:
+  - Obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag()/PopItemFlag()
+    with ImGuiItemFlags_ButtonRepeat. Kept inline redirecting functions (will obsolete).
+  - Obsoleted PushTabStop()/PopTabStop() in favor of using new PushItemFlag()/PopItemFlag()
+    with ImGuiItemFlags_NoTabStop. Kept inline redirecting functions (will obsolete).
+  - Renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups for
+    consistency. Kept inline redirecting functions (will obsolete).
+    + Internals: changed/inverted ImGuiItemFlags_SelectableDontClosePopup (default==false) to
+      ImGuiItemFlags_AutoClosePopups (default==true), same logic, only inverted behavior.
+    (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
+- Commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)
+- Commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)
+    - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.
+- Backends: GLFW+Emscripten: Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to
+  ImGui_ImplGlfw_InstallEmscriptenCallbacks(), with an additional GLFWWindow* parameter. (#7647) [@ypujante]
+
+Other changes:
+
+- Added TextLink(), TextLinkOpenURL() hyperlink widgets. (#7660)
+- IO: added io.PlatformOpenInShellFn handler to open a link/folder/file in OS shell. (#7660)
+  Added IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS to disable default Windows/Linux/Mac implementations.
+- IO: added io.ConfigNavSwapGamepadButtons to swap Activate/Cancel (A<>B) buttons, to match the
+  typical "Nintendo/Japanese consoles" button layout when using Gamepad navigation. (#787, #5723)
+- Added PushItemFlag()/PopItemFlags(), ImGuiItemFlags to modify shared item flags:
+   - Added ImGuiItemFlags_NoTabStop to disable tabbing through items.
+   - Added ImGuiItemFlags_NoNav to disable any navigation and focus of items. (#787)
+   - Added ImGuiItemFlags_NoNavDefaultFocus to disable item being default focus. (#787)
+   - Added ImGuiItemFlags_ButtonRepeat to enable repeat on any button-like behavior.
+   - Added ImGuiItemFlags_AutoClosePopups to disable menu items/selection auto closing parent popups.
+     Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().
+     (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
+   - This was mostly all previously in imgui_internal.h.
+- Multi-Select: added multi-select API and demos. (#1861, #6518)
+   - This system implements standard multi-selection idioms (CTRL+mouse click, CTRL+keyboard moves,
+     SHIFT+mouse click, SHIFT+keyboard moves, etc.) with support for clipper (not submitting non-visible
+     items), box-selection with scrolling, and many other details.
+   - In the spirit of Dear ImGui design, your code owns both items and actual selection data.
+     This is designed to allow all kinds of selection storage you may use in your application
+     (e.g. set/map/hash, intrusive selection, interval trees, up to you).
+   - The supported widgets are Selectable(), Checkbox(). TreeNode() is also technically supported but...
+     using this correctly is more complicated. You need some sort of linear/random access to your tree,
+     which is suited to advanced trees setups already implementing filters and clipper.
+     We will work toward simplifying our existing demo for trees.
+   - A helper ImGuiSelectionBasicStorage is provided to facilitate getting started in a typical app
+     (likely to suit a majority of users).
+   - Documentation:
+     - Wiki page https://github.com/ocornut/imgui/wiki/Multi-Select for API overview.
+     - Demo code + headers are well commented.
+  - Added BeginMultiSelect(), EndMultiSelect(), SetNextItemSelectionUserData().
+  - Added IsItemToggledSelection() for use if you need latest selection update during current iteration.
+  - Added ImGuiMultiSelectIO and ImGuiSelectionRequest structures:
+    - BeginMultiSelect() and EndMultiSelect() return a ImGuiMultiSelectIO structure, which
+      is mostly an array of ImGuiSelectionRequest actions (clear, select all, set range, etc.)
+    - Other fields are helpful when using a clipper, or wanting to handle deletion nicely.
+  - Added ImGuiSelectionBasicStorage helper to store and maintain a selection (optional):
+    - This is similar to if you used e.g. a std::set<ID> to store a selection, with all the right
+      glue to honor ImGuiMultiSelectIO requests. Most applications can use that.
+  - Added ImGuiSelectionExternalStorage helper to maintain an externally stored selection (optional):
+    - Helpful to easily bind multi-selection to e.g. an array of checkboxes.
+  - Added ImGuiMultiSelectFlags options:
+    - ImGuiMultiSelectFlags_SingleSelect
+    - ImGuiMultiSelectFlags_NoSelectAll
+    - ImGuiMultiSelectFlags_NoRangeSelect
+    - ImGuiMultiSelectFlags_NoAutoSelect
+    - ImGuiMultiSelectFlags_NoAutoClear
+    - ImGuiMultiSelectFlags_NoAutoClearOnReselect (#7424)
+    - ImGuiMultiSelectFlags_BoxSelect1d
+    - ImGuiMultiSelectFlags_BoxSelect2d
+    - ImGuiMultiSelectFlags_BoxSelectNoScroll
+    - ImGuiMultiSelectFlags_ClearOnEscape
+    - ImGuiMultiSelectFlags_ClearOnClickVoid
+    - ImGuiMultiSelectFlags_ScopeWindow (default), ImGuiMultiSelectFlags_ScopeRect
+    - ImGuiMultiSelectFlags_SelectOnClick (default), ImGuiMultiSelectFlags_SelectOnClickRelease
+    - ImGuiMultiSelectFlags_NavWrapX
+  - Demo: Added "Examples->Assets Browser" demo.
+  - Demo: Added "Widgets->Selection State & Multi-Select" section, with:
+    - Multi-Select
+    - Multi-Select (with clipper)
+    - Multi-Select (with deletion)
+    - Multi-Select (dual list box) (#6648)
+    - Multi-Select (in a table)
+    - Multi-Select (checkboxes)
+    - Multi-Select (multiple scopes)
+    - Multi-Select (tiled assert browser)
+    - Multi-Select (trees) (#1861)
+    - Multi-Select (advanced)
+- Inputs: added SetItemKeyOwner(ImGuiKey key) in public API.
+  This is a simplified version of a more complete set of function available in imgui_internal.h.
+  One common use-case for this is to allow your widgets to disable standard inputs behaviors such
+  as Tab or Alt handling, Mouse Wheel scrolling, etc.
+  (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
+     // Hovering or activating the button will disable mouse wheel default behavior to scroll
+     InvisibleButton(...);
+     SetItemKeyOwner(ImGuiKey_MouseWheelY);
+- Nav: fixed clicking window decorations (e.g. resize borders) from losing focused item when
+  within a child window using ImGuiChildFlags_NavFlattened.
+- InputText: added '\' and '/' as word separator. (#7824, #7704) [@reduf]
+- TreeNode: added SetNextItemStorageID() to specify/override the identifier used for persisting
+  open/close storage. Useful if needing to often read/write from storage without manipulating
+  the ID stack. (#7553, #6990, #3823, #1131)
+- Selectable: added ImGuiSelectableFlags_Highlight flag to highlight items independently from
+  the hovered state. (#7820) [@rerilier]
+- Clipper: added SeekCursorForItem() function. When using ImGuiListClipper::Begin(INT_MAX) you can
+  can use the clipper without knowing the amount of items beforehand. (#1311)
+  In this situation, call ImGuiListClipper::SeekCursorForItem(items_count) at the end of your iteration
+  loop to position the layout cursor correctly. This is done automatically if provided a count to Begin().
+- Groups, Tables: fixed EndGroup() failing to correctly capture current table occupied size. (#7543)
+- Style, TabBar: added style.TabBarOverlineSize / ImGuiStyleVar_TabBarOverlineSize to manipulate
+  thickness of the horizontal line over selected tabs. [@DctrNoob]
+- Style: close button and collapse/window-menu button hover highlight made rectangular instead of round.
+- Misc: added GetID(int) variant for consistency. (#7111)
+- Debug Tools:
+  - Debug Log: Added IMGUI_DEBUG_LOG(), ImGui::DebugLog() in public API. (#5855)
+    Printed entries include imgui frame counter prefix + are redirected to ShowDebugLogWindow() and
+    other configurable locations. Always call IMGUI_DEBUG_LOG() for maximum stripping in caller code.
+  - Debug Log: Added "Configure Outputs.." button. (#5855)
+  - Debug Log: Fixed incorrect checkbox layout when partially clipped.
+- Demo: Reworked "Property Editor" demo in a manner that more resemble the tree data and
+  struct description data that a real application would want to use.
+- Backends:
+  - Backends: Win32: Fixed ImGuiMod_Super being mapped to VK_APPS instead of (VK_LWIN || VK_RWIN).
+    (#7768, #4858, #2622) [@Aemony]
+  - Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership change. (#7807)
+  - Backends: SDL3: Update for API changes: SDL_GetClipboardText() memory ownership change. (#7801)
+  - Backends: SDL3: Update for API changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762)
+  - Backends: SDL3: Update for API changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794) [@wermipls]
+  - Backends: SDL2,SDL3,OSX: Update for io.SetPlatformImeDataFn() -> io.PlatformSetImeDataFn() rename.
+  - Backends: GLFW,SDL2: Added io.PlatformOpenInShellFn handler for web/Emscripten versions. (#7660)
+    [@ypujante, @ocornut]
+  - Backends; GLFW+Emscripten: Added support for GLFW3 contrib port which fixes many of the things
+    not supported by the embedded GLFW: gamepad support, mouse cursor shapes, copy to clipboard,
+    workaround for Super/Meta key, different ways of resizing, multi-window (glfw/canvas) support.
+    (#7647) [@ypujante]
+  - Backends: GLFW+Emscripten: Fixed Emscripten warning when using mouse wheel on some setups
+    "Unable to preventDefault inside passive event listener". (#7647, #7600) [@ypujante]

+ VERSION 1.90.9 (Released 2024-07-01)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.9
+
+Breaking changes:
+
+- Removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to
+  ImGuiStoragePair (simpler for many languages). No significant nested type left.
+- BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window
+  flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for
+  BeginChild() calls anyhow. (#7687) [@cfillion]
+   - old: BeginChild("Name", size, 0, ImGuiWindowFlags_NavFlattened);
+   - new: BeginChild("Name", size, ImGuiChildFlags_NavFlattened, 0)
+  Kept inline redirection flag (will obsolete).
+- Style: renamed tab colors for clarity and consistency with other changes: (#261, #351)
+  - ImGuiCol_TabActive          -> ImGuiCol_TabSelected
+  - ImGuiCol_TabUnfocused       -> ImGuiCol_TabDimmed
+  - ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected
+  Kept inline redirecting enums (will obsolete).
+- IO: io.ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data.
+  Newly added io.ClearInputMouse() does. (#4921)
+- Drag and Drop: renamed ImGuiDragDropFlags_SourceAutoExpirePayload to
+  ImGuiDragDropFlags_PayloadAutoExpire. Kept inline redirecting enum (will obsolete). (#1725, #143)
+
+Other changes:
+
+- IO: do not disable io.ConfigWindowsResizeFromEdges (which allow resizing from borders
+  and lower-left corner) when ImGuiBackendFlags_HasMouseCursors is not set by backend.
+  The initial reasoning is that resizing from borders feels better when correct mouse cursor
+  shape change as honored by backends. Keeping this enabling will hopefully increase pressure
+  on third-party backends to set ImGuiBackendFlags_HasMouseCursors and honor changes of
+  ImGui::GetMouseCursor() value. (#1495)
+- IO: do not claim io.WantCaptureMouse=true on the mouse release frame of a button
+  which was pressed over void/underlying app, which is consistent/needed to allow the
+  mouse up event of a drag over void/underlying app to catch release. (#1392) [@Moka42]
+- IO: Added io.ClearInputMouse() to clear mouse state. (#4921)
+- Windows: BeginChild(): fixed a glitch when during a resize of a child window which is
+  tightly close to the boundaries of its parent (e.g. with zero WindowPadding), the child
+  position could have temporarily be moved around by erroneous padding application. (#7706)
+- TabBar, Style: added ImGuiTabBarFlags_DrawSelectedOverline option to draw an horizontal
+  line over selected tabs to increase visibility. This is used by docking.
+  Added corresponding ImGuiCol_TabSelectedOverline and ImGuiCol_TabDimmedSelectedOverline colors.
+- Tables: added TableGetHoveredColumn() to public API, as an alternative to testing for
+  'TableGetColumnFlags(column) & ImGuiTableColumnFlags_IsHovered' on each column. (#3740)
+- Disabled, Inputs: fixed using Shortcut() or SetNextItemShortcut() within a disabled block
+  bypassing the disabled state. (#7726)
+- Disabled: Reworked 1.90.8 behavior of Begin() not inheriting current BeginDisabled() state,
+  to make it that only tooltip windows are temporarily clearing it. (#211, #7640)
+- Drags: added ImGuiSliderFlags_WrapAround flag for DragInt(), DragFloat() etc. (#7749)
+- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern sets
+  active id so a multi-frame extern source doesn't interfere with hovered widgets. (#143)
+- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern does not assume
+  a mouse button being pressed. Facilitate implementing cross-context drag and drop. (#143)
+- Drag and Drop: Added ImGuiDragDropFlags_PayloadNoCrossContext/_PayloadNoCrossProcess flags
+  as metadata to specify that a payload may not be copied outside the context/process by
+  some logic aiming to copy payloads around.
+- Drag and Drop: Fixes an issue when elapsing payload would be based on last payload
+  frame instead of last drag source frame, which makes a difference if not resubmitting
+  payload every frame. (#143)
+- Debug Tools: Metrics/Debugger: Browsing a Storage perform hover lookup on identifier.
+- Viewports: Backported 'void* ImGuiViewport::PlatformHandle' from docking branch for
+  use by backends.
+- imgui_freetype: Fixed divide by zero while handling FT_PIXEL_MODE_BGRA glyphs. (#7267, #3369)
+- Backends: OpenGL2, OpenGL3: ImGui_ImplOpenGL3_NewFrame() recreates font texture if it
+  has been destroyed by ImGui_ImplOpenGL3_DestroyFontsTexture(). (#7748) [@mlauss2]
+- Backends: SDL3: Update for API removal of keysym field in SDL_KeyboardEvent. (#7728)
+- Backends: SDL3: Update for SDL_StartTextInput()/SDL_StopTextInput() API changes. (#7735)
+- Backends: SDL3: Update for SDL_SetTextInputRect() API rename. (#7760, #7754) [@maxortner01]
+- Backends: SDLRenderer3: Update for SDL_RenderGeometryRaw() API changes. (SDL#9009).
+- Backends: Vulkan: Remove Volk/ from volk.h #include directives. (#7722, #6582, #4854)
+  [@martin-ejdestig]
+- Examples: SDL3: Remove use of SDL_HINT_IME_NATIVE_UI since new SDL_HINT_IME_IMPLEMENTED_UI
+  values has a more suitable default for our case case.
+- Examples: GLFW+Vulkan, SDL+Vulkan: handle swap chain resize even without Vulkan
+  returning VK_SUBOPTIMAL_KHR, which doesn't seem to happen on Wayland. (#7671)

+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.8
+
+Breaking changes:
+
+- Reordered various ImGuiInputTextFlags values. This should NOT be breaking unless
+  you are using generated headers that have values not matching the main library.
+- Removed ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft
+  from imgui.h, was mostly unused and misleading.
+
+Other changes:
+
+- Inputs: fixed IsMouseClicked(..., repeat=true); broken in 1.90.7 on 2024/05/22.
+  (due to an internal api parameter swap, repeat wouldn't be honored and
+  ownership would be accidentally checked even though this api is meant to not
+  check ownership). (#7657) [@korenkonder]
+- Windows: fixed altering FramePadding mid-frame not correctly affecting logic
+  responsible for honoring io.ConfigWindowsMoveFromTitleBarOnly. (#7576, #899)
+- Scrollbar: made scrolling logic more standard: clicking above or below the
+  grab scrolls by one page, holding mouse button repeats scrolling. (#7328, #150)
+- Scrollbar: fixed miscalculation of vertical scrollbar visibility when required
+  solely by the presence of an horizontal scrollbar. (#1574)
+- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_ParseEmptyRefVal
+  to parse an empty field as zero-value. (#7305) [@supermerill, @ocornut]
+- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_DisplayEmptyRefVal
+  to display a zero-value as empty. (#7305) [@supermerill, @ocornut]
+- Popups: fixed an issue preventing to close a popup opened over a modal by clicking
+  over void (it required clicking over the visible part of the modal). (#7654)
+- Tables: fixed an issue where ideal size reported to parent container wouldn't
+  correctly take account of inner scrollbar, affecting potential auto-resize of
+  parent container. (#7651)
+- Tables: fixed a bug where after disabling the ScrollY flag for a table,
+  previous scrollbar width would be accounted for. (#5920)
+- Combo: simplified Combo() API uses a list clipper (due to its api it wasn't
+  previously trivial before we added clipper.IncludeItemByIndex() function).
+- Disabled: nested tooltips or other non-child window within a BeginDisabled()
+  block disable the disabled state. (#211, #7640)
+- Misc: made ImGuiDir and ImGuiSortDirection stronger-typed enums.
+- Backends: SDL3: Update for SDL_SYSTEM_CURSOR_xxx api renames. (#7653)

+//-----------------------------------------------------------------------------
+
+// Multi-selection system
+// Documentation at: https://github.com/ocornut/imgui/wiki/Multi-Select
+// - Refer to 'Demo->Widgets->Selection State & Multi-Select' for demos using this.
+// - This system implements standard multi-selection idioms (CTRL+Mouse/Keyboard, SHIFT+Mouse/Keyboard, etc)
+//   with support for clipper (skipping non-visible items), box-select and many other details.
+// - Selectable(), Checkbox() are supported but custom widgets may use it as well.
+// - TreeNode() is technically supported but... using this correctly is more complicated: you need some sort of linear/random access to your tree,
+//   which is suited to advanced trees setups also implementing filters and clipper. We will work toward simplifying and demoing it.
+// - In the spirit of Dear ImGui design, your code owns actual selection data.
+//   This is designed to allow all kinds of selection storage you may use in your application e.g. set/map/hash.
+// About ImGuiSelectionBasicStorage:
+// - This is an optional helper to store a selection state and apply selection requests.
+// - It is used by our demos and provided as a convenience to quickly implement multi-selection.
+// Usage:
+// - Identify submitted items with SetNextItemSelectionUserData(), most likely using an index into your current data-set.
+// - Store and maintain actual selection data using persistent object identifiers.
+// - Usage flow:
+//     BEGIN - (1) Call BeginMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (2) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 6.
+//           - (3) [If using clipper] You need to make sure RangeSrcItem is always submitted. Calculate its index and pass to clipper.IncludeItemByIndex(). If storing indices in ImGuiSelectionUserData, a simple clipper.IncludeItemByIndex(ms_io->RangeSrcItem) call will work.
+//     LOOP  - (4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.
+//     END   - (5) Call EndMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (6) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 2.
+//     If you submit all items (no clipper), Step 2 and 3 are optional and will be handled by each item themselves. It is fine to always honor those steps.
+// About ImGuiSelectionUserData:
+// - This can store an application-defined identifier (e.g. index or pointer) submitted via SetNextItemSelectionUserData().
+// - In return we store them into RangeSrcItem/RangeFirstItem/RangeLastItem and other fields in ImGuiMultiSelectIO.
+// - Most applications will store an object INDEX, hence the chosen name and type. Storing an index is natural, because
+//   SetRange requests will give you two end-points and you will need to iterate/interpolate between them to update your selection.
+// - However it is perfectly possible to store a POINTER or another IDENTIFIER inside ImGuiSelectionUserData.
+//   Our system never assume that you identify items by indices, it never attempts to interpolate between two values.
+// - If you enable ImGuiMultiSelectFlags_NoRangeSelect then it is guaranteed that you will never have to interpolate
+//   between two ImGuiSelectionUserData, which may be a convenient way to use part of the feature with less code work.
+// - As most users will want to store an index, for convenience and to reduce confusion we use ImS64 instead of void*,
+//   being syntactically easier to downcast. Feel free to reinterpret_cast and store a pointer inside.
