# 7.2.2

This is the 7.2.2 release. Below are listed the bug fixes and feature additions that have gone into this release.

## Known Issues

- Synthetic Building Filters are not yet implemented
- Long visualization operations can lock up the GUI. Please be patient for those operations to end.
- Compute Feature Centroids will not respect periodic boundaries in a model
- The Anaconda version will not save your GUI window layout correctly. The workaround is to create a layout to your liking and save it as a preset.
- Computing Volumes from Triangle Features will not work correctly unless all triangle normals are consistent and the surface mesh is watertight.

## Feature & Bug Fixes of Note

- Users can now change the background color of the render window
- Add a new filter "Read Zeiss TXM" that can read .txm files
- Add a new filter "Combine Transformation Matrices"
- Rewrote the DBSCAN filter realizing an order of magnitude speed up
- Several bug fixes to the Apply Transformation to Geometry filter
