+ VERSION 1.92.8 (Released 2026-05-12)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.8
+
+Breaking Changes:
+
+- DrawList: swapped the last two arguments of `AddRect()`, `AddPolyline()`, `PathStroke()`.
+   - Before: `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, ImDrawFlags flags = 0, float thickness = 1.0f);`
+   - After:  `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, float thickness = 1.0f, ImDrawFlags flags = 0);`
+   - Before: `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, ImDrawFlags flags, float thickness);`
+   - After:  `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, float thickness, ImDrawFlags flags = 0);`
+   - Before: `void ImDrawList::PathStroke(ImU32 col, ImDrawFlags flags = 0, float thickness = 1.0f);`
+   - After:  `void ImDrawList::PathStroke(ImU32 col, float thickness = 1.0f, ImDrawFlags flags = 0);`
+  Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off.
+  Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking.
+  Effectively the typical call site is changing from:
+   - Before: `window->DrawList->AddRect(p_min, p_max, color, rounding, ImDrawFlags_None, border_size);`
+   - After:  `window->DrawList->AddRect(p_min, p_max, color, rounding, border_size);`
+  Notes:
+   - Users of C++ and other languages with type-checking will be notified at compile-time of any mistakes.
+   - Users of high-level bindings or languages with no type-checking will be notified at runtime via an assert for invalid flags value.
+     If you are a binding maintainer consider doing something to facilitate transition or error detection.
+   - This is perhaps the worst breaking change in our history :( but it makes ImDrawList function signatures consistent.
+     As we are aiming to add flags and features to variety of ImDrawList functions, that consistency becomes more important.
+     The new order is also more convenient as `flags` are less frequently used than `thickness` in real code.
+   - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites.
+   - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code.
+- DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`,
+    which is part of our new standard draw callbacks. (#9378)
+    Redirecting the earlier value into the later one when set, so both old and new code should work.
+- Backends:
+  - Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. (#914)
+    This change allows us to facilitate changing samplers, in line with other backends. [@yaz0r, @ocornut]
+    - When creating your own descriptor pool (instead of letting backend creates its own):
+      - Before: need at least `IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`.
+      - After:  need at least `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`.
+                            + `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE`       descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`.
+    - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
+      - Before: `ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)`
+      - After:  `ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)`
+      - Kept inline redirection function that ignores the sampler (will obsolete).
+  - DirectX10, DirectX11, SDLGPU3, Vulkan: removed samplers from `ImGui_ImplXXXX_RenderState`.
+    Prefer to use backend-agnostic DrawCallback_SetSamplerLinear which works everywhere! (#9378)
+    If there is a legit need/request for them or any render state we can always add them back.
+
+Other Changes:
+
+- DrawList:
+  - Added room in `ImGuiPlatformIO` for standard backend-agnostic draw callbacks. Those callbacks
+    are setup/provided by the backend and available in most of our standard backends.
+    They allow backend-agnostic code from e.g. switching to a Nearest/Point sampler without
+    messing with custom Renderer-specific callbacks.
+      platform_io.DrawCallback_ResetRenderState;    // Request to reset the graphics/render state.
+      platform_io.DrawCallback_SetSamplerLinear;    // Request to set current texture sampling to Linear
+      platform_io.DrawCallback_SetSamplerNearest;   // Request to set current texture sampling to Nearest/Point
+    Note that some backends might not support all callbacks.
+    (#9378, #9371, #3590, #8926, #2973, #7485, #7468, #6969, #5118, #7616, #9173, #8322, #7230,
+    #5999, #6452, #5156, #7342, #7592, #7511)
+  - Made `AddCallback()` user data default to Null for convenience.
+  - Added `AddLineH()`, `AddLineV()` helpers to draw horizontal and vertical lines. [@memononen]
+- InputText:
+  - InputTextMultiline: fixed an issue processing deactivation logic when an active
+    multi-line edit is clipped due to being out of view.
+  - Fixed a crash when toggling ReadOnly while active. (#9354)
+  - `CharFilter` callback event sets CursorPos/SelectionStart/SelectionEnd. (#816)
+- Tables:
+  - Fixed issues reporting ideal size to parent window/container: (#9352, #7651)
+    - When both scrollbars are visible but only one of ScrollX/ScrollY was explicitly requested.
+    - When vertical scrollbar was not at the top, the computation was often incorrect.
+- Windows:
+  - Fixed a single-axis auto-resizing feedback loop issue with nested containers
+    and varying scrollbar visibility. (#9352)
+  - Detect and report error when calling End() instead of EndPopup() on a popup. (#9351)
+  - Child windows with only `ImGuiChildFlags_AutoResizeY` flag keep using the proportional
+    default `ItemWidth`. (#9355)
+  - Using mouse wheel to scroll takes and keeps ownership of the corresponding keys
+    (e.g. `ImGuiKey_MouseWheelY`) while a wheeling window is locked. (#2604, #3795)
+- InputInt, InputFloat, InputScalar:
+  - Reinstated `ImGuiInputTextFlags_EnterReturnsTrue` support which was removed in 1.91.4.
+    (#8665, #9299, #8065, #3946, #6284, #9117)
+    - Fixed the fact that it didn't return true when validating same value.
+    - Fixed losing value when tabbing out or losing focus.
+    - Made it that pressing +/- step buttons also return true, which is in line
+      with 1.91.4 behavior.
+    - In a majority of cases you should use `IsItemDeactivatedAfterEdit()` instead,
+      but it still has a few edge cases flaws (to be addressed soon).
+  - Allow passing a format string that does not display the scalar value.
+    Parsing input with default format for the type. (#9385) [@FireFox2000000]
+- Multi-Select:
+  - Fixed an issue using Multi-Select within a Table causing column width measurement to
+    be invalid when trailing column contents is not submitted in the last row. (#9341, #8250)
+  - Fixed an issue using Multi-Select within a Table with the right-most column visible,
+    which could lead to an extra vertical offset in the Header row. (#8250)
+- Multi-Select + Box-Select:
+  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect1d` mode while scrolling.
+    Notably, using mouse wheel while holding a box-selection could lead items close to windows
+    edges from not being correctly unselected. (#7994, #8250, #7821, #7850, #7970)
+  - Improved dirty/unclip rectangle logic for `ImGuiMultiSelectFlags_BoxSelect2d`.
+  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode, where
+    items out of view wouldn't be properly selected while scrolling while mouse cursor
+    is hovering outside of selection scope. (#7994, #1861, #6518)
+  - Fixed an issue where items out of horizontal view would sometimes lead
+    to incorrect merging of sequential selection requests while also scrolling fast
+    enough to overlap multiple rows during a frame. (#7994, #1861, #6518)
+  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode in a Table
+    while relying on the `TableNextColumn()` return value to perform coarse clipping. (#7994)
+  - Disabled merging consecutive selection requests as we have no reliable
+    way of detecting if user has submitted all consecutive items without clipping gaps,
+    and `ImGuiSelectionUserData` is technically opaque storage. (#7994, #1861)
+    (we will probably bring this back as a minor optimization if we have a way to for
+    user to tell us `ImGuiSelectionUserData` are indices)
+  - Fixes for using across nested child windows. (#8364)
+  - Box-Select + Clipper: fixed an issue selecting items while scrolling while a clipper
+    active. (#7994, #8250, #7821, #7850, #7970)
+  - Box-Select + Tables: fixed an issue using box-selection in a tables with
+    items straying out of columns boundaries. (#7994, #2221)
+  - Box-Select + Tables: fixed an issue when calling `BeginMultiSelect()` in a table
+    before layout has been locked (first row or headers row submitted). (#8250)
+- Menus:
+  - BeginMenu()/MenuItem(): fixed accidental triggering of child menu items when
+    opening a menu inside a small host window forcing the child menu window to be
+    repositioned under the mouse cursor. (#8233, #9394)
+    Done by reworking `BeginMenu()`/`MenuItem()`: they previously avoiding taking
+    ActiveID + key/click ownership (in order to allow releasing button on another item).
+    Now they take them and release them once the mouse is moved outside item boundaries.
+- Inputs:
+  - SetItemKeyOwner(): return true if ownership has been requested, which typically
+    needs to to checked for gating further tests. This is important as the function
+    may fail. (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
+  - SetItemKeyOwner(): does not set ownership is key is already taken. Effectively
+    this makes using `SetItemKeyOwner(ImGuiKey_MouseWheelY)` over an item work as
+    expected while not having item react if a scroll wheel is actively in progress.
+    May be subject to further redesign, e.g. conditional flags. Feedback welcome!
+- Style:
+  - Checkbox: added `ImGuiCol_CheckboxSelectedBg` to change or accentuate the
+    background color of checked/mixed checkboxes. (#9392)
+  - Added `ImGuiStyleVar_DragDropTargetRounding`. (#9056)
+  - Fixed vertical scrollbar top coordinates when using thick borders on windows
+    with no title bar and no menu bar. (#9366)
+- Fonts:
+  - imgui_freetype: add FreeType headers & compiled version in 'About Dear ImGui' details.
+  - Assert when using MergeMode with an explicit size over a target font with an implicit
+    size, as scale factor are likely erroneous. (#9361)
+- Clipper:
+  - Improved error reporting when misusing the clipper inside a table (prioritize
+    reporting the common clipper error over a table sanity check assert). (#9350)
+  - Tweaked assert triggering when first item height measurement fails, and made it
+    a better recoverable error. (#9350)
+- Misc:
+  - Minor optimization: reduce redundant label scanning in common widgets.
+  - Added missing Test Engine hooks for `PlotLines()`, `PlotHistogram()`, `VSliderXXX()`
+    and `TableHeader()` functions.
+- Demo:
+  - Added simple demo for a scrollable/zoomable image viewer with a grid.
+    Available in `Examples->Image Viewer` and `Widgets->Images`.
+- Backends:
+  - Added support for new standardized draw callbacks in most backends: (#9378)
+    - Allegro5:     Reset     n/a               n/a
+    - DX9:          Reset     SetSamplerLinear  SetSamplerNearest
+    - DX10:         Reset     SetSamplerLinear  SetSamplerNearest
+    - DX11:         Reset     SetSamplerLinear  SetSamplerNearest
+    - DX12:         Reset     SetSamplerLinear  SetSamplerNearest
+    - Metal:        Reset     SetSamplerLinear  SetSamplerNearest
+    - OpenGL2:      Reset     SetSamplerLinear  SetSamplerNearest
+    - OpenGL3+:     Reset     SetSamplerLinear  SetSamplerNearest
+    - SDLGPU3:      Reset     SetSamplerLinear  SetSamplerNearest
+    - SDLRenderer2: Reset     n/a               n/a
+    - SDLRenderer3: Reset     SetSamplerLinear  SetSamplerNearest
+    - Vulkan:       Reset     SetSamplerLinear  SetSamplerNearest
+    - WebGPU:       Reset     SetSamplerLinear  SetSamplerNearest
+    (Vulkan backend by @yaz0r, Metal by @ssh4net, others by @ocornut)
+  - GLFW: added a Win32-specific implementation of `ImGui_ImplGlfw_GetContentScaleXXXX`
+    functions for legacy GLFW 3.2. (#9003)
+  - Metal: avoid redundant vertex buffer bind in `SetupRenderState()`, which leads
+    to validation issue. (#9343) [@Hunam6]
+  - Metal: use a dedicated `bufferCacheLock` to avoid crashing when `bufferCache` is
+    replaced by a new object while being used for `@synchronize()`. (#9367) [@andygrundman]
+  - SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()`
+    helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value
+    and this breaks scaling border size. (#9369)
+  - WebGPU: rework choice/detection of using WGSL/SPIR-V shader on WGVK. (#9316, #9246, #9257, #9387)
+- Examples:
+  - Update VS toolset in all .vcxproj from VS2015 (v140) to VS2017 (v141). The later is the
+    first that supports vcpkg. Onward we will likely stop testing building the library with VS2015.
+  - GLFW+Vulkan, SDL2+Vulkan, SDL3+Vulkan, Win32+Vulkan: reworked to create a descriptor pool with:
+    - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`.
+    - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE`       descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`.

+                         Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off.
+                         Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking.
+                         Effectively the typical call site is changing from:
+                         - Before:  window->DrawList->AddRect(p_min, p_max, color, rounding, ImDrawFlags_None, border_size);
+                         - After:   window->DrawList->AddRect(p_min, p_max, color, rounding, border_size);
+                         Notes:
+                         - Users of C++ and other languages with type-checking will be notified at compile-time of any mistakes.
+                         - Users of high-level bindings or languages with no type-checking will be notified at runtime via an assert for invalid flags value.
+                           If you are a binding maintainer consider doing something to facilitate transition or error detection.
+                         - This is perhaps the worst breaking change in our history :( but it makes ImDrawList function signatures consistent.
+                           As we are aiming to add flags and features to variety of ImDrawList functions, that consistency becomes more important.
+                           The new order is also more convenient as `flags` are less frequently used than `thickness` in real code.
+                         - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites.
+                         - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code.
+ - 2026/04/23 (1.92.8) - DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`, which is part of our new standard draw callbacks. (#9378)
+ - 2026/04/22 (1.92.8) - Backends: Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler.
+                         - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
+                         - When creating your own descriptor pool (instead of letting backend creates its own): need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE + IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
 - 2026/03/19 (1.92.7) - MultiSelect: renamed ImGuiMultiSelectFlags_SelectOnClick to ImGuiMultiSelectFlags_SelectOnAuto.
 - 2026/02/26 (1.92.7) - 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)

  `stlrh`, `stlr`, `ldarb`, `ldarh`, `ldar`, `clrex`.

+Security Considerations
+-----------------------
+
+VIXL allows callers to generate any code they want. The generated code is
+arbitrary, and can therefore call back into any other component in the process.
+As with any self-modifying code, vulnerabilities in the client or in VIXL itself
+could lead to arbitrary code generation.
+
+For performance reasons, VIXL's Assembler only performs debug-mode checking of
+instruction operands (such as immediate field encodability). This can minimise
+code-generation overheads for advanced compilers that already model instructions
+accurately, and might consider the Assembler's checks to be redundant. The
+Assembler should only be used directly where encodability is independently
+checked, and where fine control over all generated code is required.
+
+The MacroAssembler synthesises multiple-instruction sequences to support _some_
+unencodable operand combinations. The MacroAssembler can provide a useful safety
+check in cases where the Assembler's precision is not required; an unexpected
+unencodable operand should result in a macro with the correct behaviour, rather
+than an invalid instruction.
+
+In general, the MacroAssembler handles operands which are likely to vary with
+user-supplied data, but does not usually handle inputs which are likely to be
+easily covered by tests. For example, move-immediate arguments are likely to be
+data-dependent, but register types (e.g. `x` vs `w`) are not.
+
+We recommend that _all_ users use the MacroAssembler, using `ExactAssemblyScope`
+to invoke the Assembler when specific instruction sequences are required. This
+approach is recommended even in cases where a compiler can model the
+instructions precisely, because, subject to the limitations described above, it
+offers an additional layer of protection against logic bugs in instruction
+selection.

 that all of VIXL's dependencies are in place and that VIXL is working as it

-By default, the `tools/test.py` script runs a linter to check that the source
-code conforms with the code style guide, and to detect several common errors
-that the compiler may not warn about. This is most useful for VIXL developers.
-The linter has the following dependencies:
-
- 1. Git must be installed, and the VIXL project must be in a valid Git

- 2. `cpplint.py`, [as provided by Google][cpplint], must be available (and
