+ VERSION 1.90.8 WIP (In Progress)
+-----------------------------------------------------------------------
+
+Breaking changes:

+Other changes:
+
+- Windows: fixed altering FramePadding mid-frame not correctly affecting logic
+  responsible for honoring io.ConfigWindowsMoveFromTitleBarOnly. (#7576, #899)
+- Scrollbar: made scrolling logic more standard: clicking above or below the
+  grab scrolls by one page, holding mouse button repeats scrolling. (#7328, #150)
