Fmriprep

--------------------------
* Hotfix release (dependencies and deployment system)

--------------------------
* ENH: Added an option to choose the degrees of freedom used when doing BOLD to T1w coregistration (``--bold2t1w_dof``). Set default to 9 to account for field inhomogeneities and coils heating up (448)
* ENH: Added support for phase difference and GE style fieldmaps (448)
* ENH: Generate GrayWhite, Pial, MidThickness and inflated surfaces (398)
* ENH: Memory and performance improvements for calculating the EPI reference (436)
* ENH: Sample functional series to subject and ``fsaverage`` surfaces (391)
* ENH: Output spaces for functional data may be selected with ``--output-space`` option (447)
* ENH: ``--skip-native`` functionality replaced by ``--output-space`` (447)
* ENH: ``fmriprep-docker`` wrapper script simplifies running in a Docker environment (317)

-------------------------
With thanks to Asier Erramuzpe for contributions.

* ENH: Added optional slice time correction (415)
* ENH: Removed redundant motion parameter conversion step using avscale (415)
* ENH: FreeSurfer submillimeter reconstruction may be disabled with ``--no-submm-recon`` (422)
* ENH: Switch bbregister init from ``fsl`` to ``coreg`` (FreeSurfer native 423)
* ENH: Motion estimation now uses a smart reference image that takes advantage of T1 saturation (421)
* FIX: Fix report generation with ``--reports-only`` (427)

--------------------------
* ENH: Perform bias field correction of EPI images prior to coregistration (409)
* FIX: Fix an orientation issue affecting some datasets when bbregister was used (408)
* ENH: Minor improvements to the reports aesthetics (428)

--------------------------
* FIX: Affine and warp MNI transforms are now applied in the correct order
* ENH: Added preliminary support for reconstruction of cortical surfaces using FreeSurfer
* ENH: Switched to bbregister for BOLD to T1 coregistration
* ENH: Switched to sinc interpolation of preprocessed BOLD and T1w outputs
* ENH: Preprocessed BOLD volumes are now saved in the T1w space instead of mean BOLD
* FIX: Fixed a bug with MCFLIRT interpolation inducing slow drift
* ENH: All files are now saved in Float32 instead of Float64 to save space

----------------------------
* Initial public release
