1.2.0

New features and enhancements

• Improve the assignment of field maps to functional scans, print
  warnings when detecting an incomplete field map or when a complete
  field map is not recognized by fMRIPrep (#115 and #192)
• Remove conditions that have no events from the task-based model. This
  is important for designs where the conditions depend on subject
  performance (#90)
• Output additional images during group mode. Voxel-wise descriptive
  statistics (#142), typical subject-level variance (#148)
• Divide outputs into subfolders to make navigating the files easier
• Output metadata to sidecar files, including resolution, field-of-view
  and field map type (#154 and #181)
• Add an option to skip dummy/non-steady-state scans and modify event
  onsets accordingly (#167, #176, #182 and #187)
• Improve performance during workflow creation (#192)

Bug fixes

• Update fMRIPrep to fix normalization bug (#51)
• Improve memory usage prediction. Fixes BrokenProcessPool and
  Killed: 137 errors (#125, #156 and #157)
• Refactor Dockerfile to correctly re-build matplotlib caches
  (#107)
• Fix assignment of event files to functional scans. Make sure that the
  assignment is consistent between what is shown in the user interface
  and during workflow creation. Add unit tests (#139)
• Fix crashes for datasets deviating from the BIDS specification
  and remove misleading warnings for incompatible and hidden files
• Fix AssertionError crash when no group model is specified
• Rephrase user interface for loading .mat event files. Do not say
  that the time unit (seconds or scans) is missing, which was
  confusing.
• Fix various crashes when running on a cluster
• Fix user interface crash when no categorical variables are defined in
  a spreadsheet
• Fix loading subject-level results during group model. Get rid of
  LoadResult nodes, instead use a subclass of Node (#137)
• Use slower but more robust least-squares solve for group statistics
  (#141)
• Fix performance issue during t2z_convert procedure during group
  statistics (#143, #144 and #145)
• Remove output from heterogeneity group statistics that was causing
  performance issues (#146)
• Fix confusing EOFError message on exit by gracefully stopping
  child processes before exit (#130 and #160)
• Fix running FreeSurfer with run_reconall option (#87)
• Add error message when running on an unsupported file system such as
  FAT (#102)
• Fix confusing error message when no features are specified (#147)
• Re-scale fd_perc output to percent (#186)
• Reduce user interface memory usage (#191)
• Fix automated testing hanging on the logging worker (#192)

Maintenance

• Update Python to version 3.8
• Update templateflow, pybids, nibabel
• Pin dipy version due to incompatibility with nipype
• Pin indexed_gzip version due to incompatibility of newer version
  with some files (#85)
• Add new Singularity container build workflow (#97 and #138)
• Improve documentation to suggest running Singularity with
  --containall instead of --no-home --cleanenv
• Refactor code to use defaultdict to increase readability
• Add more type hints
• Rename main branch from master to main
• Add pre-commit and pip-tools to better manage dependencies
• Install as many dependencies as possible via conda and the rest
  via pip (#164)
• Refactor workflow code to allow handling of surface-based functional
  images (#161)
• In-progress refactor model package into schema package. Use
  dataclasses for better integration with type checkers (#173, #174
  and #178)
