fMRIPrep 20.0.0rc2 (February 18, 2020) ====================================== The second and last release candidate of the new major version 20.x.x series. *fMRIPrep* is transitioning to a calendar version system (`#1912 <https://github.com/poldracklab/fmriprep/issues/1912>`__). The `CalVer <https://calver.org/>`__ system reflects *fMRIPrep*'s nature as an evolving workflow and does not impose any artificial incentive for "big-change" releases. It also permits to quickly see how out-of-date someone's version is. As of now, the *default* version increment is the minor release number. Hence, when the minor release number changes the work directory of *fMRIPrep* will presumably break. Micro releases only include bug-fixes that can reuse exiting working directories. The major highlight of this release entails CIFTI generation to match :abbr:`HCP (Human Connectome Project)` *grayordinates*. In addition, the new *fMRIPrep 20.0.0* has gone through a major overhaul in the handling of standard spaces (spatial normalizations, fusion of prior knowledge from corresponding atlases) and imaging outputs. In particular, the new series almost completely implements the new syntax for ``--output-spaces`` to describe the (non)standard spatial references that shall be used for generating outputs (`#1604 <https://github.com/poldracklab/fmriprep/issues/1604>`__). This release includes contributions from Azeez Adebimpe and Basile Pinsard - very much appreciated. * ENH: Warn when existing output version does not match current pipeline version (#1967) * ENH: Add ``--clean-workdir`` argument (#1966) * ENH: Refactor of how spatial normalization targets and ``--output-spaces`` are maintained (#1955) (#1983) * ENH: Add ``--bids-filter-file`` argument for more controlled data querying (#1770) * FIX: Ensure subject ID is used when selecting BIDS data (#1982) * FIX: Display a log message when processing completes successfully (#1977) * DOC: Improve custom template usage description (#1969) * MAINT: Pin connectome-workbench 1.3.2, add to documented dependencies (#1958) * MAINT: Pin NiBabel, NiWorkflows, sMRIPrep (#1971) * MAINT: CI build error fixes (#1976)
