* (rapidtide) Simplified specification of output files. Now use "--outputlevel" with values "min", "normal", "more", or "max" to specify what files are output.
* (rapidtide) Improved motion regression and made it more flexible.
* (rapidtide) Merged all bids nifti file writes into a common output routine.
* (retroglm, rapidtide) Factored out all the GLM calculation code so it can be done (or redone with different options) after the fact with "retroglm" as a separate step.
* (retroglm, rapidtide) Allow arbitrary number of derivatives of lagged regressors, and properly save all EVs and fit coefficients.
* (niftidecomp) Now output raw variance explained in addition to variance explained ratio.
* (tidepool) Now show graphically what part of the probe regressor was used for similarity calculation.
* (package) Replaced the "mlregress" routine of unknown provenance with LinearRegression from sklearn.
* (package) Merged some dependabot PRs.
* (docs) Added a section on output data size.
