This blog is updated daily.
A general description is here.
‘_R_CHECK_DEPENDS_ONLY_’ can be applied selectively to examples, tests and/or vignettes in ‘R CMD check’: see the “R Internals” manual.
The legacy S-compatibility macros ‘PROBEM’, ‘MESSAGE’, ‘ERROR’, ‘WARN’, ‘WARNING’, ‘RECOVER’, ... are deprecated and are no longer defined by default in ‘R_exts/RS.h’ (included by ‘R.h’). Replace these by calls to ‘Rf_error’ and ‘Rf_warning’.
For the time being the definitions can be reinstated by defining macro ‘R_LEGACY_S_DEFS’ to ‘1’ _before_ including any R header. Header ‘R_ext/RS.h’ will no longer include ‘R_ext/Error.h’ unless ‘R_LEGACY_S_DEFS’ is set.
[Early warning: removal planned for Oct 8.]
‘hist(<Date>, ...)’ and ‘hist(<POSIXt>, ...)’ no longer pass arguments for ‘rect()’, such as ‘col’ and ‘density’, to ‘axis()’. (Thanks to Sebastian Meyer's PR#18171.)
New palettes ‘"Rocket"’ and ‘"Mako"’ for ‘hcl.colors()’ (approximating palettes of the same name from the ‘viridisLite’ package).
