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

Breaking Changes:
|
||||
- ImDrawList: Fixed rectangles with thick lines (>1.0f) not being as thick as requested. (#2518)
|
||||
If you have custom rendering using thick lines, they will appear thicker now.
|
||||
- ImDrawList: Improved algorithm for mitre joints on thick lines, preserving correct thickness
|
||||
up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines,
|
||||
they will appear a little thicker now. (#2518) [@rmitton]
|
||||
- Obsoleted GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead.
|
||||
Kept inline redirection function.
|
||||
- Examples: Vulkan: Added MinImageCount/ImageCount fields in ImGui_ImplVulkan_InitInfo, required

Examples: Added support for ImDrawCallback_ResetRenderState in all renderer back-ends. Each
|
||||
renderer code setting up initial render state has been moved to a function so it could be
|
||||
called at the start of rendering and when a ResetRenderState is requested. [@ocornut, @bear24rw]
|
||||
- InputText: Fixed selection background starts rendering one frame after the cursor movement
|

when first transitioning from no-selection to has-selection. (Bug in 1.69) (#2436) [@Nazg-Gul]

|

- InputText: Work-around for buggy standard libraries where isprint('\t') returns true. (#2467, #1336)
|

- InputText: Fixed ImGuiInputTextFlags_AllowTabInput leading to two tabs characters being inserted
|

if the back-end provided both Key and Character input. (#2467, #1336)

- Window: Close button is horizontally aligned with style.FramePadding.x.
|
||||
- Window: Fixed contents region being off by WindowBorderSize amount on the right when scrollbar is active.

instead of restoring the window that was in the window stack at the time of the OpenPopup call. (#2517)

GL function loaders early, and help users understand what they are missing. (#2421)
