+0.16.0 (July 31, 2024)
+======================
+Start of the 0.16.x minor series.

+to allow easier integration with tools less reliant on a single anatomical scan.
+
+* ENH: Use genericised "anat" input/output for TemplateDimensions (#443)
+* ENH: Remove much of the hardcoded `T1w` fields in favor of `anat` (#433)
+* RF: Load package data with acres (#448)
+* RF: `space-fsaverage` to `sphere_reg` output files (#446)
+* MNT: Unpin libitk 5.3 (ANTs 2.5.3 is built with 5.4) (#445)
+* MNT: Clean up doc builds, environment, style checks (#444)
+
+
