+v1.9.0
+====================
+
+**Added:**
+
+* Added a how-to guide for defining a custom ``Component`` (`PR #667 <https://github.com/OpenFreeEnergy/gufe/pull/667>`_).
+* Added a ``.validate()`` method to gufe Components (`PR #732 <https://github.com/OpenFreeEnergy/gufe/pull/732>`_).
+* ``gufe.protocol.protocoldag.execute_DAG`` now has the ability to resume DAG execution by passing in a path for results caching into ``cache_basedir`` (`PR #738 <https://github.com/OpenFreeEnergy/gufe/pull/738>`_).
+* Added two new Components, a ``SolvatedPDBComponent`` for explicitly solvated systems, including periodic box vectors, and a ``ProteinMembraneComponent`` that inherits from ``SolvatedPDBComponent`` and can be used downstream for type checking of solvated protein membrane appropriate settings (`PR #635 <https://github.com/OpenFreeEnergy/gufe/pull/635>`_).
+* Added a ``ComponentValidationError`` type to be used specifically when ``Component.validate()``  fails (`PR #766 <https://github.com/OpenFreeEnergy/gufe/pull/766>`_).
+
+**Changed:**
+
+* Sped up the counting of the number of water molecules in a SolvatedPDBComponent (`PR #751 <https://github.com/OpenFreeEnergy/gufe/pull/751>`_).
+* ``amber/lipid17_merged.xml`` is now defined by default in forcefield list in :class:`OpenMMSystemGeneratorFFSettings` (`PR #767 <https://github.com/OpenFreeEnergy/gufe/pull/767>`_).
