A general description is here.
‘Sys.which()’ now returns ‘NA’ (not ‘""’) for ‘NA’ inputs (related to PR#15147).
The ‘print()’ method for class ‘"htest"’ gives fewer trailing spaces (wish of PR#15124).
Also output from ‘HoltWinters()’, ‘nls()’ and others.
‘embedFonts()’ needed to quote some filepaths. (PR#15149)
‘parallel::mccollect()’ handled ‘NULL’ returns incorrectly (removing the element rather than setting it to ‘NULL’).
Under Windows, ‘file.link()’ and ‘file.symlink()’ used the link name twice, so would always fail. (Reported by Rui Barradas/Oliver Soong).
