   `#934 <https://github.com/pybind/pybind11/pull/934>`_.
 
+* Add basic support for tag-based static polymorphism, where classes
+  provide a method to returns the desired type of an instance.
+  `#1326 <https://github.com/pybind/pybind11/pull/1326>`_.
+
 * Added support for write only properties.
   `#1144 <https://github.com/pybind/pybind11/pull/1144>`_.
 
-* The ``value()``  method of ``py::enum_`` now accepts an optional docstring
-  that will be shown in the documentation of the associated enumeration.
+* A number of improvements related to enumerations:
+
+   1. The ``enum_`` implementation was rewritten from scratch to reduce
+      code bloat. Rather than instantiating a full implementation for each
+      enumeration, most code is now contained in a generic base class.
+      `#1511 <https://github.com/pybind/pybind11/pull/1511>`_.
+
+   2. The ``value()``  method of ``py::enum_`` now accepts an optional
+      docstring that will be shown in the documentation of the associated
+      enumeration. `#1160 <https://github.com/pybind/pybind11/pull/1160>`_.
+
+   3. check for already existing enum value and throw an error if present.
+      `#1453 <https://github.com/pybind/pybind11/pull/1453>`_.
+
+* added ``py::ellipsis()`` method for slicing of multidimensional NumPy arrays
+  `#1502 <https://github.com/pybind/pybind11/pull/1502>`_.
+
+* ``pybind11_add_module()``: allow including Python as a ``SYSTEM`` include path.
+  `#1416 <https://github.com/pybind/pybind11/pull/1416>`_.

+-----------------------------------------------------
+
+* Use new Python 3.7 Thread Specific Storage (TSS) implementation if available.
+  `#1454 <https://github.com/pybind/pybind11/pull/1454>`_,
+  `#1517 <https://github.com/pybind/pybind11/pull/1517>`_.
+
+* Fixes for newer MSVC versions and C++17 mode.
+  `#1347 <https://github.com/pybind/pybind11/pull/1347>`_,
+  `#1462 <https://github.com/pybind/pybind11/pull/1462>`_.
+
+* Propagate return value policies to type-specific casters
+  when casting STL containers.
+  `#1455 <https://github.com/pybind/pybind11/pull/1455>`_.
+
+* Allow ostream-redirection of more than 1024 characters.
+  `#1479 <https://github.com/pybind/pybind11/pull/1479>`_.
+
+* Set ``Py_DEBUG`` define when compiling against a debug Python build.
+  `#1438 <https://github.com/pybind/pybind11/pull/1438>`_.
+
+* Untangle integer logic in number type caster to work for custom
+  types that may only be castable to a restricted set of builtin types.
+  `#1442 <https://github.com/pybind/pybind11/pull/1442>`_.
+
+* CMake build system: Remember Python version in cache file.
+  `#1434 <https://github.com/pybind/pybind11/pull/1434>`_.
+
+* Fix for custom smart pointers: use ``std::addressof`` to obtain holder
+  address instead of ``operator&``.
+  `#1435 <https://github.com/pybind/pybind11/pull/1435>`_.
+
+* Properly report exceptions thrown during module initialization.
+  `#1362 <https://github.com/pybind/pybind11/pull/1362>`_.
+
+* Fixed a segmentation fault when creating empty-shaped NumPy array.
+  `#1371 <https://github.com/pybind/pybind11/pull/1371>`_.
+
+* The version of Intel C++ compiler must be >= 2017, and this is now checked by
+  the header files. `#1363 <https://github.com/pybind/pybind11/pull/1363>`_.
+
+* A few minor typo fixes and improvements to the test suite, and
+  patches that silence compiler warnings.
