+- [unicodedata] Addded new module ``fontTools.unicodedata`` which exports the
+  same interface as the built-in ``unicodedata`` module, with the addition of
+  a few functions that are missing from the latter, such as ``script``,
+  ``script_extension`` and ``block``. Added a ``MetaTools/buildUCD.py`` script
+  to download and parse data files from the Unicode Character Database and
+  generate python modules containing lists of ranges and property values.
+- [feaLib] Added ``__str__`` method to all ``ast`` elements (delegates to the
+  ``asFea`` method).
+- [feaLib] ``Parser`` constructor now accepts a ``glyphNames`` iterable
+  instead of ``glyphMap`` dict. The latter still works but with a pending
+  deprecation warning (#1104).
+- [bezierTools] Added arc length calculation functions originally from
+  ``pens.perimeterPen`` module (#1101).
+- [varLib] Started generating STAT table (8af4309). Right now it just reflects
+  the axes, and even that with certain limitations:
+    * AxisOrdering is set to the order axes are defined,
+    * Name-table entries are not shared with fvar.
+- [py23] Added backports for ``redirect_stdout`` and ``redirect_stderr``
+  context managers (#1097).
+- [Graphite] Fixed some round-trip bugs (#1093).
+
 3.19.0 (released 2017-11-06)
