@ -28,6 +28,19 @@ HOW TO UPDATE?
and API updates have been a little more frequent lately. They are documented below and in imgui.cpp and should not affect all users.
- Please report any issue!
-----------------------------------------------------------------------
VERSION 1.71 (In Progress)
-----------------------------------------------------------------------
Breaking Changes:
Other Changes:
- Columns: Fixed Separator from creating an extraneous draw command. (#125)
- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125)
- Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect
but it breaks existing some layout patterns. Will return back to it when we expose Separator flags.
- Scrollbar: Very minor bounding box adjustment to cope with various border size.

- window/child: the first draw command of a child window could be moved into the current draw command of the parent window (unless child+tooltip?).
- window/child: border could be emitted in parent as well.
- window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
