 Breaking Changes
 ++++++++++++++++
 * The very old model names `ResultInput`, `Result`, `ResultProperties`, `Optimization` deprecated in 2019 are now only available through `qcelelemental.models.v1`
+* ``models.v2`` do not support AutoDoc. The AutoDoc routines have been left at pydantic v1 syntax. Use autodoc-pydantic for Sphinx instead.
 
 New Features
 ++++++++++++
 * Downstream code should ``from qcelemental.models.v1 import Molecule, AtomicResult`` etc. to assure medium-term availability of existing models.
+* New pydantic v2 models available as ``from qcelemental.models.v2 import Molecule, AtomicResult`` etc.
 
 Enhancements
 ++++++++++++
+* The ``models.v2`` have had their `schema_version` bumped for ``BasisSet``, ``AtomicInput``, ``OptimizationInput`` (implicit for ``AtomicResult`` and ``OptimizationResult``), ``TorsionDriveInput`` , and ``TorsionDriveResult``.
+* The ``models.v2`` ``AtomicResultProperties`` has been given a ``schema_name`` and ``schema_version`` (2) for the first time.
+* Note that ``models.v2`` ``QCInputSpecification`` and ``OptimizationSpecification`` have *not* had schema_version bumped.
