                            The new order is also more convenient as `flags` are less frequently used than `thickness` in real code.
                          - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites.
                          - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code.
+ - 2026/05/07 (1.92.8) - DrawList: changed value of `ImDrawFlags_Closed`. It was previously advertised as "always == 1" when introduced in 1.82 (2021/02), in order to facilitate backward compatibility with the legacy `bool closed` flag.
+                         This guarantee has been removed. The bit is reserved and `AddPolyline()`, `PathStroke()` will assert when it is used.
  - 2026/04/23 (1.92.8) - DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`, which is part of our new standard draw callbacks. (#9378)
  - 2026/04/22 (1.92.8) - Backends: Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler.
                          - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
