I have posted a new release (5.5-Sep-2018) in full installer and executable-only versions. Minor changes to help file.
The changes (taken from the update log) are:
Stack Images: fixed problem with initial curve display as Histograms.
Median Blur: applying variable median blur to 16-bit black and white or 48-bit color results in 8-bit black and white or 24-bit color image.
