+Overview of changes leading to 1.5.0
+Wednesday, August 23, 2017
+====================================
+
+- Misc new API, for appending a buffer to another, and for comparing
+  contents of two buffers for types of differences.
+
+- New "unsafe-to-break" API.  Can be used to speed up reshaping
+  in line-breaking situations.  Essentially, after shaping, it returns
+  positions in the input string (some of the cluster boundaries) that
+  are "safe to break" in that if the text is segmented at that position
+  and two sides reshaped and concatenated, the shaping result is
+  exactly the same as shaping the text in one piece.
+
+  hb-view and hb-shape and hb-shape now take --verify, which verifies
+  the above property.
+
+  Some corner cases of the implementation are still not quite working.
+  Those will be fixed in subsequent releases.
