+This is a major relase including a new minimizer, support for installing from PyPI using pip, performance improvements, documentation improvements, and bug fixes.
+
+* ENH: Introduce a new energy minimizer based on the method described by [Sundman2015]_.
+  The new minimizer improves performance, convergence for dilute and pseudo-binary systems,
+  and reduces the point grid density (memory) required for convergence.
+  ( :issue:`329`, :issue:`332`, :issue:`336`, :issue:`339`, :issue:`343`, :issue:`344` )
+* BLD: Improve the build system to support PEP 517 and PEP 518 isolated builds and
+  the ``pyproject.toml`` standard. ( :issue:`330`, :issue:`331`, :issue:`334` )
+* BLD: Distributed pycalphad wheels on PyPI in addition to the conda-forge package.
+  Using pip to install pycalphad is now supported and recommended. ( :issue:`346` )
+* ENH: Improve performance of ``Model`` instantiation ( :issue:`340` )
+* MAINT: Add support for pyparsing 3.0 ( :issue:`348` )
