@@ -51,6 +51,7 @@ Other Changes:
 - Window: Fixed default proportional item width lagging by one frame on resize.
 - Window: Fixed popups/tooltips/menus not honoring style.DisplaySafeAreaPadding as well as it should have (part of menus displayed outside the safe area, etc.).
 - Window: Fixed windows using the ImGuiWindowFlags_NoSavedSettings flag from not using the same default position as other windows. (#1760)
+- Columns: Fixed a bug introduced in 1.51 where columns would affect the contents size of their container, often creating feedback loops when ImGuiWindowFlags_AlwaysAutoResize was used. (#1760)
 - MenuBar: Made BeginMainMenuBar() honor style.DisplaySafeAreaPadding so the text can be made visible on TV settings that don't display all pixels. (#1439) [@dougbinks]
 - InputText: On a Mac, filter out characters when the Cmd modifier is held. (#1747) [@sivu]
 - Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439)
