@@ -36,6 +36,8 @@ HOW TO UPDATE?
 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.
+- Obsoleted GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead.
+  Kept inline redirection function.
 - Examples: Vulkan: Added MinImageCount/ImageCount fields in ImGui_ImplVulkan_InitInfo, required
   during initialization to specify the number of in-flight image requested by swap chains.
   (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). (#2071, #1677) [@nathanvoglsam]

  - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
  - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
  - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with a dummy small value!
