The breakage are generally minor and easy to fix. Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code. - - 2015/05/31 (1.39) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). - - 2015/05/31 (1.39) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). - - 2015/05/27 (1.39) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. - - 2015/05/11 (1.39) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "opened" state of a popup.
