+Overview of changes leading to 2.9.1
+Tuesday, September 7, 2021
+====================================
+- Final subset API is in place and if no issues are discovered, it will be the
+  stable subset API of HarfBuzz 3.0.0. Old API is kept to ease transition, but
+  will be removed in 3.0.0.
+- Various fuzzer-found bug fixes.
+- hb_buffer_append() now handles the pre- and post-context which previously
+  were left unchanged in the destination buffer.
+- hb-view / hb-shape now accept following new arguments:
+  o --unicodes: takes a list of hex numbers that represent Unicode
+    codepoints.
+- Undeprecated API:
+  hb_set_invert()
