+#########
+
+1.2 (not yet released)
+--------------------------
+* Optional: efficient generation of function signatures at compile time using C++14
+* Switched to a simpler and more general way of dealing with function default arguments
+  Unused keyword arguments in function calls are now detected and cause errors as expected
+* New ``keep_alive`` call policy analogous to Boost.Python's ``with_custodian_and_ward``
+* Improved interface for RAII type wrappers in ``pytypes.h``
+* Use RAII type wrappers consistently within pybind11 itself. This
+  fixes various potential refcount leaks when exceptions occur
+* Added new ``bytes`` RAII type wrapper (maps to ``string`` in Python 2.7).
+* Made handle and related RAII classes const correct
+* Got rid of the ugly ``__pybind11__`` attributes on the Python side---they are
+  now stored in a C++ hash table that is not visible in Python
+* Fixed refcount leaks involving NumPy arrays and bound functions
+* Vastly improved handling of shared/smart pointers
+* Removed an unnecessary copy operation in ``pybind11::vectorize``
+* Fixed naming clashes when both pybind11 and NumPy headers are included
+* Added conversions for additional exception types
+* Documentation improvements (using multiple extension modules, smart pointers, other minor clarifications)
+* Fixed license text (was: ZLIB, should have been: 3-clause BSD)
+* Python 3.2 compatibility
+
+1.1 (December 7, 2015)
+--------------------------
+
+* Documentation improvements (GIL, wrapping functions, casting, fixed many typos)
+* Generalized conversion of integer types
+* Improved support for casting function objects
+* Improved support for ``std::shared_ptr<>`` conversions
+* Initial support for ``std::set<>`` conversions
+* Fixed type resolution issue for types defined in a separate plugin module
+* Cmake build system improvements
+* Factored out generic functionality to non-templated code (smaller code size)
+* Added a code size / compile time benchmark vs Boost.Python
+* Added an appveyor CI script
+
+1.0 (October 15, 2015)
+------------------------
+* Initial release
