BUG FIXES:

• The change to the internal table in R 4.0.4 for iswprint has been
  reverted: it contained some errors in printability of 'East
  Asian' characters.

• For packages using LazyData, R CMD build ignored the
  --resave-data option and the BuildResaveData field of the
  DESCRIPTION file (in R versions 4.0.0 to 4.0.4).
