 ## [Unreleased]

+## [0.16.3] - 2024-03-14
 ### Added
 - BaseNode: Add diameter property.
 - Misc: Testing to include benchmark timings for tree creation, compare benchmark tests across commits, reject pull request if benchmark tests fails.
 - Misc: Documentation to include benchmark results.
 ### Changed
 - Misc: Documentation to enable zooming in of images, add navigation section headers, remove some meta tags.
 - Misc: Split up testing into multiple conftest files.
+### Fixed
+- Tree Constructor: Tree creation from dictionary adds None for empty attributes instead of np.nan.
+- [#216] Tree Exporter: `attr_omit_null` to handle nan/null values in addition to checking for None.
