+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.
