+## [0.1.1] - 2023-10-17
+
+### Changed
+- Adjusted shape of `data.property.constraints.planning` and added a `PlanningConstraint` definition ([#50](https://github.com/theopensystemslab/digital-planning-data-schemas/pull/50))
+- Added more granular values to the `ProjectType` definition ([#55](https://github.com/theopensystemslab/digital-planning-data-schemas/pull/55))
+- Improved examples, especially `data.proposal.details` ([#54](https://github.com/theopensystemslab/digital-planning-data-schemas/pull/54))
+- Minor naming and organisational adjustments throughout based on early feedback
+
+### Fixed
+- Corrected usage of JSON Schema `Date` format ([#52](https://github.com/theopensystemslab/digital-planning-data-schemas/pull/52))
+
+### Removed

+
+## [0.1.0] - 2023-10-04
