+v1.5.4
+====================
+
+**Added:**
+
+* Python bindings to the ``Position`` class.
+* Input validation for Latitude and Longitude
+* New `Mocksim::DummyProto` where capacity and commodity of the prototype can be defined.
+* The Python typesystem generator has been extended to include
+  types that should be passed by their C++ shared pointers, such
+  as resources. ``Materials`` and ``Products`` have thus been added as
+  fully valid types on their own in the typesystem.  Note that since
+  resources already have classes of their own in the typesystem, state
+  variables for these classes are ``MaterialStateVar`` and ``ProductStateVar``.
+* Added the Decision Phase. This phase occurs after the tock phase and allows
+  cyclus agents to make decisions based on what has occured during the
+  tick and tock phase of the current timestep. 
+
+
+**Changed:**
+
+* `cycpp.py` now takes advantage of the `$CPP` environment variable if defined,
+  falls back on `cpp` if not defined
+* `cyclus_deps` docker container built now on debian9, removed gcc from apt-get
+  package, build the full list of conda package (don't rely on cyclus-deps conda
+  package as it is temporary broken), define CXX CC and CPP environment variable
+* `cython` compatibility limited to >=0.25 and <0.27
+* ``dbtypes_gen.py`` will now throw approriate errors for incorrect
+  JSON in ``queryable_backend.h``.
+* Python interface will now raise exceptions when it encounters an error in C++ or
+  Cython.
+* Updated cycstub readme to reflect changes
+* Updated the record time series function to also include the name of the field being
+  recorded. 
+
+
+
+**Deprecated:**
+
+
+**Fixed:**
+
+* `boost/uuid/sha1.hpp` include now varies according to the Boost version
+  installed due to its deprecation in boost > 1.67
+* Python inventories required a value for ``capacity`` even though it was optional. This
+  change also enables ``None`` valued capacities, which are treated as infinite.
+* Fixed issue where resource buffer Python bidnings would attempt to append to
+  the resources themselves when popping resources out of the buffers.
+* Fixed issue when pushing many resources to a resource buffer would attempt to
+  append the entire buffer
+* Error in generation of ``dbtypes.json`` file led to incorrect
+  enumeration of of some database types. This in turn led to segfaults
+  when using these types in the Python typesystem. It also made the HDF5
+  backend generator skip some types.
+* Invalid JSON in ``queryable_backend.h`` has been fixed.
+* Fixed cycstub build issue which failed to find Cyclus shared libraries
+* Fixed cycstub unit test issue that failed to locate stub library shared object
+
