# 7.4.2

This is the 7.4.2 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

- New Quad View visualization module with synchronized 3D volume rendering and three orthogonal or oblique slice views, thick-slab projections, measurement rulers, markers, and comprehensive color controls.
- Major charting improvements, including multi-series histograms, grouped or overlaid bars, cumulative distribution curves, secondary axes, and unified chart navigation.
- Generate complete Python scripts and filter snippets directly from pipelines, bookmarks, and the Filter List.

## New Filters

- **Group MicroTexture Regions** groups neighboring features in hexagonal materials when their c-axes are aligned within a specified tolerance.
- **Keep/Remove Ranked Features** keeps or removes features by rank, count, percentage, or contribution to a measured quantity.
- **Create Surface Mesh (M3C Multi-Material Marching Cubes)** generates a conformal triangle mesh from a segmented multi-feature volume.
- **Read Image** is a non-ITK replacement for **Read Image (ITK)** that reads a PNG, JPEG, BMP, or TIFF image into an Image Geometry.
- **Read NIfTI File (Version 1)** reads `.nii` and compressed `.nii.gz` scientific and medical volumes.
- **Regularize Z Spacing** resamples serial-section data with irregular slice positions onto a uniformly spaced Z grid.
- **Write Image** is a non-ITK replacement for **Write Image (ITK)** that writes two-dimensional images or volume slices as PNG, JPEG, BMP, or TIFF files, with optional color mapping, image flipping, and a physical scale bar.
