0d483a1c89f Backends: OpenGL3: Update loader for Linux to support EGL/GLVND. (#7562)
92df32d3390 Backends: OpenGL3: minor update of generated loader to match latest downloaded glcorearb.h/khrplatform.h files.
1ab1af80c74 Backends: Win32: Facepalm revert part of d15574c + additional commentary (#6275)
d15574ce2a5 Backends: Win32: Removed silent return when calling ImGui_ImplWin32_WndProcHandler() with no active context! (#6275)

0b309471f2e Windows: Changed default ClipRect to extend to windows' left and right borders. (#3312, #7540, #3756, #6170, #6365)
0c9c12c1bb9 InnerClipRect use ImFloor() matching docking branch (fix c41868531 for #6861, #2884, followed by rename 94da5842)
6ebbecc6a08 Realign assignments.
fc4d818e170 Tables: Angled headers: added TableAngledHeadersTextAlign, ImGuiStyleVar_TableAngledHeadersTextAlign. (#6917)

b720c0f541c Backends: Vulkan: Added convenience support for Volk via IMGUI_IMPL_VULKAN_USE_VOLK define. (#6582, #4854)
07e8ff9a8d4 Backends: Win32: Fixed a warning + moved header cruft below Changelog.
fa0120ea5ea Windows: Fixed subsequent Begin() append calls from setting last item information for title-bar. (#7506, #823)
361432a0bb2 TreeNode: fixed layout so that TreeNode("") or TreeNode("##HiddenLabel") may properly be used with SameLine(0,0). (#7505, #282)
eba46cb0d22 Drag and Drop: assert when nesting  BeginDragDropSource() and BeginDragDropTarget() (#7504) + update Gallery links

VERSION 1.90.6 WIP (In Progress) 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: 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: 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. - Fonts: Fixed font ascent and descent calculation when a font hits exact integer values.

duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC] 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 - Text, DrawList: Improved handling of long single-line wrapped text. Faster and

- 2024/04/18 (1.90.6) - TreeNode: Fixed a layout inconsistency when using an empty/hidden label followed by a SameLine() call. (#7505, #282)
- old: 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).
- new: TreeNode("##Hidden"); SameLine(0, 0); Text("Hello"); // <-- This is correct for all styles values.
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).
