New features
  • ArrayProxy method get_scaled() scales data with a dtype of a specified precision, promoting as necessary to avoid overflow. This is to used in img.get_fdata() to control memory usage. (pr/833) (CM, reviewed by Ross Markello)
  • GiftiImage method agg_data() to return usable data arrays (pr/793) (Hao-Ting Wang, reviewed by CM)
  • Accept os.PathLike objects in place of filenames (pr/610) (Cameron Riddell, reviewed by MB, CM)
  • Function to calculate obliquity of affines (pr/815) (Oscar Esteban, reviewed by MB)
Enhancements
  • get_fdata(dtype=np.float32) will attempt to avoid casting data to np.float64 when scaling parameters would otherwise promote the data type unnecessarily. (pr/833) (CM, reviewed by Ross Markello)
  • ArraySequence now supports a large set of Python operators to combine or update in-place. (pr/811) (MC, reviewed by Serge Koudoro, Philippe Poulin, CM, MB)
  • Warn, rather than fail, on DICOMs with unreadable Siemens CSA tags (pr/818) (Henry Braun, reviewed by CM)
  • Improve clarity of coordinate system tutorial (pr/823) (Egor Panfilov, reviewed by MB)
Bug fixes
  • Sliced Tractograms no longer apply_affine to the original Tractogram's streamlines. (pr/811) (MC, reviewed by Serge Koudoro, Philippe Poulin, CM, MB)
  • Re-import externals/netcdf.py from scipy to resolve numpy deprecation (pr/821) (CM)
Maintenance
  • Support Python >=3.5.1, including Python 3.8.0 (pr/787) (CM)
  • Manage versioning with slightly customized Versioneer (pr/786) (CM)
  • Reference Nipy Community Code and Nibabel Developer Guidelines in GitHub community documents (pr/778) (CM, reviewed by MB)
API changes and deprecations
  • Deprecate ArraySequence.data in favor of ArraySequence.get_data(), which will return a copy. ArraySequence.data now returns a read-only view. (pr/811) (MC, reviewed by Serge Koudoro, Philippe Poulin, CM, MB)
  • Deprecate DataobjImage.get_data() API, to be removed in nibabel 5.0 (pr/794, pr/809) (CM, reviewed by MB)
