The R Core Team released R 3.5.3, last week. R 3.5.3 explores bug fixes to the functions writeLines, setClassUnion, and stopifnot. R 3.5.3 is a minor release and does not consist of many new changes or improvements.

  • Detection of flags has been improved for C++ 98/11/14/17.
  • There’s a new macro ‘F_VISIBILITY’ chosen as an alternative for ‘F77_VISIBILITY’. This new macro will now become the preferred form in R 3.6.0.
  • The issue in writeLines (readLines (fnam), fnam) has been fixed. It now works as expected.
  • setClassUnion () no longer sends warnings to its users. It instead uses message() on encountering “non local” subclasses in class members.
  • The failure issue in stopifnot (exprs = T) has been fixed.
