 - Please report any issue!

+-----------------------------------------------------------------------
+ VERSION 1.92.0 WIP (In Progress)
+-----------------------------------------------------------------------
+
+Breaking changes:
+
+- Backends: SDL3: Fixed casing typo in function name: (#8509, #8163, #7998, #7988) [@puugz]
+  - Imgui_ImplSDLGPU3_PrepareDrawData() -> ImGui_ImplSDLGPU3_PrepareDrawData()
+
+Other changes:
+
+- IO: variations in analog-only components of gamepad events do not interfere
+  with trickling of mouse position events (#4921, #8508)
+- Windows: fixed SetNextWindowCollapsed()/SetWindowCollapsed() breaking
+  codepath that preserve last contents size when collapsed, resulting in
+  programmatically uncollapsing auto-sizing windows having them flicker size
+  for a frame. (#7691) [@achabense]
+- Windows: loosened code to allow hovering of resize grips, borders, and table
+  borders while hovering a sibling child window, so that the code in master matches
+  one in docking (they accidentally diverged). (#8554)
+- TreeNode: added flags to draw tree hierarchy outlines linking parent
+  and tree nodes: (#2920)
+  - ImGuiTreeNodeFlags_DrawLinesNone: No lines drawn (default value in style.TreeLinesFlags).
+  - ImGuiTreeNodeFlags_DrawLinesFull: Horizontal lines to child nodes. Vertical line drawn down to TreePop() position: cover full contents.
+  - ImGuiTreeNodeFlags_DrawLinesToNodes: Horizontal lines to child nodes. Vertical line drawn down to bottom-most child node.
+  - Added style.TreeLinesFlags which stores the default setting, 
+    which may be overriden in individual TreeNode() calls.
+  - Added style.TreeLinesSize (default to 1.0f).
+  - Added ImGuiCol_TreeLines (in default style this is the same as ImGuiCol_Border).
+  - Caveats:
+    - Tree nodes may be used in many creative ways (manually positioning openable
+      nodes in unusual ways, using indent to create tree-looking structures, etc.)
+      and the feature may not accurately represent them in every cases.
+    - The feature adds a little cost as extra data needs to be stored.
+- Nav: fixed assertion when holding gamepad FaceLeft/West button to open
+  CTRL+Tab windowing + pressing a keyboard key. (#8525)
+- Error Handling: added better error report and recovery for extraneous
+  EndPopup() call. (#1651, #8499)
+- Fonts: word-wrapping code handle ideographic comma & full stop (U+3001, U+3002). (#8540)
+- Fonts: fixed CalcWordWrapPositionA() fallback when width is too small to wrap:
+  would use a +1 offset instead of advancing to the next UTF-8 codepoint. (#8540)
+- Style, InputText: added ImGuiCol_InputTextCursor to configure color of
+  the InputText cursor/caret. (#7031)
+- Misc: added extra operators to ImVec4 in IMGUI_DEFINE_MATH_OPERATORS block. (#8510) [@gan74]
+- Backends: SDL2, SDL3, OSX: Fill gamepad inputs and set ImGuiBackendFlags_HasGamepad
+  regardless of ImGuiConfigFlags_NavEnableGamepad being set. (#8508)
+- Backends: SDL2, SDL3: don't attempt to call SDL_CaptureMouse() on drivers where we don't
+  call SDL_GetGlobalMouseState(). This is specifically for Wayland but we currently use
+  the same white-list as SDL_GetGlobalMouseState(). (#8561) [@vs49688]
+- Backends: SDL3: Update for SDL3 api changes: revert SDL_GetClipboardText()
+  memory ownership change. (#8530, #7801) [@Green-Sky]
+- Backends: SDLGPU3: Made ImGui_ImplSDLGPU3_PrepareDrawData() reuse GPU Transfer Buffers which
+  were unusually slow to recreate every frame. Much faster now. (#8534) [@ocornut, @TheMode]
+- Backends: Vulkan: Deep-copy ImGui_ImplVulkan_InitInfo::PipelineRenderingCreateInfo's
+  pColorAttachmentFormats buffer when set, in order to reduce common user-error of
+  specifying a pointer to data that gets out of scope. (#8282)

 - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(), ImGui::IsKeyDown(). Removed GetKeyIndex(), now unnecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.
                        - IsKeyPressed(MY_NATIVE_KEY_XXX)              -> use IsKeyPressed(ImGuiKey_XXX)
                        - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX))      -> use IsKeyPressed(ImGuiKey_XXX)
-                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes).
+                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to still function with legacy key codes).
                        - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.*
                     - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
                     - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
