+=====================
+This release adds several new registration templates and techniques, providing 
+major improvements in bundle segmentation with waypoint ROIs. In addition, new 
+visualization methods using plotly were introduced, to generate HTML-based 
+visualizations of bundles, and to compare longitudinal measurements. This version
+relies on pybids for parsing of input datasets. Many other bug fixes and improvements.
