// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-11-11: Vulkan: Added support for specifying which subpass to reference during VkPipeline creation.
// 2020-09-07: Vulkan: Added VkPipeline parameter to ImGui_ImplVulkan_RenderDrawData (default to one passed to ImGui_ImplVulkan_Init).
// 2020-05-04: Vulkan: Fixed crash if initial frame has no vertices.
// 2020-04-26: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData didn't have vertices.

@ -127,20 +127,36 @@ Other Changes:
- Tab Bar: Made it possible to append to an existing tab bar by calling BeginTabBar()/EndTabBar() again.
- Tab Bar: Fixed using more than 128 tabs in a tab bar (scrolling policy recommended).
- Tab Bar: Do not display a tooltip if the name already fits over a given tab. (#3521)
- Tab Bar: Fixed minor/unlikely bug skipping over a button when scrolling left with arrows.
- Drag and Drop: Fix losing drop source ActiveID (and often source tooltip) when opening a TreeNode()
or CollapsingHeader() while dragging. (#1738)
- Drag and Drop: Fix drag and drop to tie same-size drop targets by choosen the later one. Fixes dragging
into a full-window-sized dockspace inside a zero-padded window. (#3519, #2717) [@Black-Cat]
- Checkbox: Added CheckboxFlags() helper with int* type.
- InputText: Fixed updating cursor/selection position when a callback altered the buffer in a way
where the byte count is unchanged but the decoded character count changes. (#3587) [@gqw]
- Nav: Fixed IsItemFocused() from returning false when Nav highlight is hidden because mouse has moved.
It's essentially been always the case but it doesn't make much sense. Instead we will aim at exposing
feedback and control of keyboard/gamepad navigation highlight and mouse hover disable flag. (#787, #2048)
- Metrics: Fixed mishandling of ImDrawCmd::VtxOffset in wireframe mesh renderer.
- Misc: Replaced UTF-8 decoder by branchless one by Christopher Wellons (30~40% faster). [@rokups]
Super minor fix handling incomplete UTF-8 contents: if input does not contain enough bytes, decoder
- Metrics: Rebranded as "Dear ImGui Metrics/Debugger" to clarify its purpose.
- Misc: Made the ItemFlags stack shared, so effectively the ButtonRepeat/AllowKeyboardFocus states
(and others exposed in internals such as PushItemFlag) are inherited by stacked Begin/End pairs,
vs previously a non-child stacked Begin() would reset those flags back to zero for the stacked window.
- Misc: Replaced UTF-8 decoder with one based on branchless one by Christopher Wellons. [@rokups]
Super minor fix handling incomplete UTF-8 contents: if input does not contain enough bytes, decoder
returns IM_UNICODE_CODEPOINT_INVALID and consume remaining bytes (vs old decoded consumed only 1 byte).
- Misc: Fix format warnings when using gnu printf extensions in a setup that supports them (gcc/mingw). (#3592)
- Misc: Made EndFrame() assertion for key modifiers being unchanged during the frame (added in 1.76) more
lenient, allowing full mid-frame releases. This is to accommodate the use of mid-frame modal native
windows calls, which leads backends such as GLFW to send key clearing events on focus loss. (#3575)
- Backends: OpenGL3: Use glGetString(GL_VERSION) query instead of glGetIntegerv(GL_MAJOR_VERSION, ...)
when the later returns zero (e.g. Desktop GL 2.x). (#3530) [@xndcn]
- Backends: OpenGL3: Backup and restore GL_PRIMITIVE_RESTART state. (#3544) [@Xipiryon]
- Backends: Vulkan: Added support for specifying which subpass to reference during VkPipeline creation. (@3579) [@bdero]
- Backends: OSX: Fix keypad-enter key not working on MacOS. (#3554) [@rokups, @lfnoise]
- Examples: Apple+Metal: Consolidated/simplified to get closer to other examples. (#3543) [@warrenm]
- Examples: Apple+Metal: Forward events down so OS key combination like Cmd+Q can work. (#3554) [@rokups]
- Docs: Split examples/README.txt into docs/BACKENDS.md and docs/EXAMPLES.md improved them.
- Docs: Consistently renamed all occurences of "binding" and "back-end" to "backend" in comments and docs.
