 -----------------------------------------------------------------------

+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.7
+
 Breaking changes:

+- Inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent(),
+  as this naturally align with how macOS X uses those keys. (#2343, #4084, #5923, #456)
+  - Effectively it means that e.g. ImGuiMod_Ctrl | ImGuiKey_C is a valid idiomatic shortcut
+    for both Windows and Mac style users.
+  - It shouldn't really affect your code unless you had explicit/custom shortcut swapping in
+    place for macOS X apps in your input logic.
+  - Removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super.
+    It is now unnecessary to specific cross-platform idiomatic shortcuts.
+    Kept symbols redirecting ImGuiMod_Shortcut to ImGuiMod_Ctrl (will obsolete).
+- Commented out obsolete symbols renamed in 1.88 (May 2022):
+    CaptureKeyboardFromApp() -> SetNextFrameWantCaptureKeyboard()
+    CaptureMouseFromApp()    -> SetNextFrameWantCaptureMouse()
+- Backends: SDL_Renderer2/SDL_Renderer3: ImGui_ImplSDLRenderer2_RenderDrawData() and
+  ImGui_ImplSDLRenderer3_RenderDrawData() now takes a SDL_Renderer* parameter. This was previously
+  overlooked from the API but it will allow eventual support for multi-viewports.
+
 Other changes:

+- Windows: BeginChild(): fixed visibility of fully clipped child windows and tables to Test Engine.
+- Windows: BeginChild(): fixed auto-fit calculation when using either (not both) ResizeX/ResizeY
+  and double-clicking on a border. Calculation incorrectly didn't always account for scrollbar as
+  it assumed the other axis would also be auto-fit. (#1710)
+- Inputs: added shortcut and routing system in public API. (#456, #2637) [BETA]
+  - The general idea is that several callers may register interest in a shortcut, and only one owner gets it.
+    - in Parent: call Shortcut(Ctrl+S)    // When Parent is focused, Parent gets the shortcut.
+    - in Child1: call Shortcut(Ctrl+S)    // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
+    - in Child2: no call                  // When Child2 is focused, Parent gets the shortcut.
+    The whole system is order independent, so if Child1 makes its calls before Parent, results will be identical.
+    This is an important property as it facilitate working with foreign code or larger codebase.
+  - Added Shortcut() function:
+    e.g. Using ImGui::Shortcut(ImGuiMod_Ctrl | ImGuiKey_C); with default policy:
+    - checks that CTRL+C is pressed,
+    - and that current window is in focus stack,
+    - and that no other requests for CTRL+C have been made from higher priority locations
+      (e.g. deeper in the window/item stack).
+  - Added SetNextItemShortcut() to set a shortcut to locally or remotely press or activate
+    an item (depending on specified routing policy: using ImGuiInputFlags_RouteGlobal the item
+    shortcut may be executed even if its window is not in focus stack).
+    Items like buttons are not fully activated, in the sense that they get pressed but another
+    active item, e.g. InputText() won't be deactivated.
+  - Added routing policies for Shortcut(), SetNextItemShortcut(): (#456, #2637)
+    - ImGuiInputFlags_RouteFocused: focus stack route (default)
+    - ImGuiInputFlags_RouteActive: only route to active item
+    - ImGuiInputFlags_RouteGlobal: route globally, unless a focus route claim shame shortcut.
+    - ImGuiInputFlags_RouteAlways: no routing submission, no routing check.
+  - Added other shortcut/routing options: (#456, #2637)
+    - ImGuiInputFlags_Repeat: for use by Shortcut() and by upcoming rework of various
+      input functions (which are still internal for now).
+    - ImGuiInputFlags_Tooltip: for SetNextItemShortcut() to show a tooltip when hovering item.
+    - ImGuiInputFlags_RouteOverFocused: global route takes priority over focus route.
+    - ImGuiInputFlags_RouteOverActive: global route takes priority over active item.
+    - ImGuiInputFlags_RouteUnlessBgFocused: global route disabled if no imgui window focused.
+    - ImGuiInputFlags_RouteFromRootWindow: route evaluated from the point of view of root window rather than current window.
+- Inputs: (OSX) Fixes variety of code which inconsistently required using Ctrl instead of Cmd.
+  - e.g. Drags/Sliders now use Cmd+Click to input a value. (#4084)
+  - Some shortcuts still uses Ctrl on Mac: e.g. Ctrl+Tab to switch windows. (#4828)
+- Inputs: (OSX) Ctrl+Left Click alias as a Right click. (#2343) [@haldean, @ocornut]
+- Inputs: Fixed ImGui::GetKeyName(ImGuiKey_None) from returning "N/A" or "None" depending
+  on value of IMGUI_DISABLE_OBSOLETE_KEYIO. It always returns "None".
+- Nav: fixed holding Ctrl or gamepad L1 from not slowing down keyboard/gamepad tweak speed.
+  Broken during a refactor refactor for 1.89. Holding Shift/R1 to speed up wasn't broken.
+- Tables: fixed cell background of fully clipped row overlapping with header. (#7575, #7041) [@prabuinet]
+- Demo: Added "Inputs & Focus -> Shortcuts" section. (#456, #2637)
+- Demo: Documents: Added shortcuts and renaming tabs/documents. (#7233)
+- Examples: Win32+DX9,DX10,DX11,DX12: rework main loop to handle minimization and screen
+  locking without burning resources by running unthrottled code. (#2496, #3907, #6308, #7615)
+- Backends: all backends + demo now call IMGUI_CHECKVERSION() to verify ABI compatibility between caller
+  code and compiled version of Dear ImGui. If you get an assert it most likely mean you have a build issue,
+  read comments near the assert. (#7568)
+- Backends: Win32: undo an assert introduced in 1.90.6 which didn't allow WndProc
+  handler to be called before backend initialization. Because of how ::CreateWindow()
+  calls in WndProc this is facilitating. (#6275) [@MennoVink]
+- Backends, Examples: SDL3: updates for latest SDL3 API changes. (#7580) [@kuvaus, @ocornut]
+
+Breaking changes IF you were using imgui_internal.h versions of Shortcut() or owner-aware
+versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked() prior to this version:
+
+- Inputs (Internals): Renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more
+  explicit and reduce confusion with the fact it is a non-zero value and cannot be a default.
+- Inputs (Internals): Renamed symbols global routes:
+      Renamed ImGuiInputFlags_RouteGlobalLow  -> ImGuiInputFlags_RouteGlobal (this is the suggested global route)
+      Renamed ImGuiInputFlags_RouteGlobal     -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused
+      Renamed ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused | ImGuiInputFlags_RouteOverActive
+- Inputs (Internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order
+  in function signatures:
+      Before: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);
+      After:  Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);
+- Inputs (Internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked():
+  swapped last two parameters order in function signatures:
+      Before: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);
+      After:  IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);

+ VERSION 1.90.6 (Released 2024-05-08)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.6
+
+Breaking changes:
+
+- TreeNode: Fixed a layout inconsistency when using a empty/hidden label followed
+  by a SameLine() call. (#7505, #282)
+     Before: TreeNode("##Hidden"); SameLine(); Text("Hello");
+             // This was actually incorrect! BUT appeared to look ok with the default style
+             // where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).
+     After:  TreeNode("##Hidden"); SameLine(0, 0); Text("Hello");
+             // This is correct for all values in style.
+  With the fix, IF you were successfully using TreeNode("")+SameLine(); you will now
+  have extra spacing between your TreeNode and the following item. You'll need to change
+  the SameLine() call to SameLine(0,0) to remove this extraneous spacing.
+  This seemed like the more sensible fix that's not making things less consistent.
+  (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).
+
+Other changes:
+
+- Windows: Changed default ClipRect to extend to windows' left and right borders,
+  instead of adding arbitrary WindowPadding.x * 0.5f space on left and right.
+  That ClipRect half-padding was arbitrary/confusing and inconsistent with Y axis.
+  It also made it harder to draw items covering whole window without pushing an
+  extended ClipRect. Some items near windows left and right edge that used to be clipped
+  may be partly more visible. (#3312, #7540, #3756, #6170, #6365)
+- Windows: Fixed subsequent Begin() append calls from setting last item information
+  for title bar, making it impossible to use IsItemHovered() on a Begin()-to-append,
+  and causing issue bypassing hover detection on collapsed windows. (#7506, #823)
 - Fonts: Fixed font ascent and descent calculation when a font hits exact integer values.
  It is possible that some prior manual use of ImFontConfig::GlyphOffset may become
  duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC]
+- TreeNode: Added ImGuiTreeNodeFlags_SpanTextWidth to make hitbox and highlight only
+  cover the label. (#6937) [@dimateos]
+- Tables: Angled headers: fixed multi-line label display when angle is flipped. (#6917)
+- Tables: Angled headers: added style.TableAngledHeadersTextAlign and corresponding
+  ImGuiStyleVar_TableAngledHeadersTextAlign variable. Default to horizontal center. (#6917)
+  [@thedmd, @ocornut]
+- ProgressBar: Added support for indeterminate progress bar by passing an animated
+  negative fraction, e.g. ProgressBar(-1.0f * GetTime()). (#5316, #5370, #1901)[@gan74]
 - Text, DrawList: Improved handling of long single-line wrapped text. Faster and
-  mitigitate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)
+  mitigate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)

+- Backends: OpenGL3: Update loader for Linux to support EGL/GLVND. (#7562) [@ShadowNinja, @vanfanel]

+  (you could always use IMGUI_IMPL_VULKAN_NO_PROTOTYPES + ImGui_ImplVulkan_LoadFunctions() as well).
+  (#6582, #4854) [@adalsteinnh, @kennyalive, @ocornut]
 - Backends: SDL3: Fixed text inputs. Re-enable calling SDL_StartTextInput()/SDL_StopTextInput()
  as SDL3 no longer enables it by default. (#7452, #6306, #6071, #1953) [@Green-Sky]
+- Examples: GLFW+Vulkan, SDL+Vulkan: Added optional support for Volk. (#6582, #4854)
+- Examples: GLFW+WebGPU: Added support for WebGPU-native/Dawn (#7435, #7132) [@eliasdaler, @Zelif]
