* (rapidtide) The ``--fixdelay`` option has been split into two options. ``--initialdelay DELAY`` lets you specify either a float that sets the starting delay for every voxel to that value, or a 3D file specifying the initial delay for each voxel. ``--nodelayfit`` determines whether the delay can be adjusted from its initial value. Closes https://github.com/bbfrederick/rapidtide/issues/171. KNOWN ISSUE: If you supply an initial delay map, instead of using the global mean, rapidtide should use the delays to make your first stage regressor. Currently that is not the case.
* (rapidtide) Reorganized command line options and adjusted the default values.
* (rapidtide) Help output now shows the filter ranges.
* (rapidtide, retroglm) Added delay refinement using the ratio of the fit coefficients of the regressor and its time derivative.
* (rapidtide, retroglm) Fixed a bad shared memory leak.
* (retroglm) Significantly enhanced logging.
* (retroglm) Added canary files.
* (rapidtide) Implemented delay map patching.
* (rapidtide) Write out individual EV timecourses.
* (Docker) Cleaned up some internal variables.
* (Docker) Improved build and testing scripts.
* (io) Added function to compare nifti files with some tolerance.
* (docs) Automated more table generation.
* (package) Merged some dependabot PRs.
* (package) Fixed a fairly big, but not necessarily impactful bug. mlregress returned R2, not R, so anything referring to the R of a fit was actually squared (R was actually R2, R2 was actually R4). NB: this does NOT affect the calculation of maxcorrsq, which does not use mlregress.
