This is a small patch release that fixes two minor bugs.
Fixed a bug in bound_correction that occurred when "region.position == 'estimate'" and a prediction x has only one unique value.
Fixed an inconsistency where the "resampling" method to calculate consistency/confidence regions required R 4.1, but DESCRIPTION stated R 3.3. The new consistent requirement is R 3.5.
ggplot2::facet_*() via the internal variable forecast (#2)monotone::monotone() is used for isotonic regression instead of stats::isoreg() (#3)"resampling" method to calculate consistency/confidence regions could not be calculated for a constant forecast.
