Made necessary changes, reran local and GH Scallywag builds, and uploaded unannounced test release, to check all works okay behind the scenes. Will not push master until ready to make another stable release. Will copy this approach going forward with other i-i.net and upstream packages with major.minor-date releases when updated. -- Take care.
