  - Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
  - Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- - Removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to enable the feature globally. (#1495)
-   The feature is not currently enabled by default because it is not satisfying enough.
+ - Removed per-window ImGuiWindowFlags_ResizeFromAnySide Beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to enable the feature globally. (#1495)
+   The feature is not currently enabled by default because it is not satisfying enough, but will eventually be.
  - InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. 
    Kept redirection types (will obsolete). 
  - InputText: Removed ImGuiTextEditCallbackData::ReadOnly since it is a duplication of (ImGuiTextEditCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
  - Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. 
    Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
  - Renamed io.OptCursorBlink to io.ConfigCursorBlink, io.OptMacOSXBehaviors to io.ConfigMacOSXBehaviors for consistency. (#1427, #473)
+-  Removed obsolete redirection functions: CollapsingHeader() variation with 2 bools - marked obsolete in v1.49, May 2016.
