This blog is updated daily.
A general description is here.
Support in ‘tools::Rdiff()’ for comparing uncompressed PDF files is further reduced - see its help page.
‘apropos()’ gains an argument ‘dot_internals’ which is used by the completion (‘help(rcompgen)’) engine to also see ‘base’ internals such as ‘.POSIXct()’.
The deprecated legacy typedefs of ‘Sint’ and ‘Sfloat’ in header ‘R.h’
can be excluded by defining macro ‘NO_S_TYPEDEFS’ before including the
header. This is defined when using ‘R CMD check --as-cran’ or by
defining the environment variable ‘_R_NO_S_TYPEDEFS_’ to a true value
when running ‘R CMD check’.
If these are excluded, ‘R.h’ no longer includes header ‘limits.h’ from C nor ‘climits’ from C++.
[This is scheduled to become the default on 2022-08-10.]
The deprecated legacy typedefs of ‘Sint’ and ‘Sfloat’ in header ‘R.h’ are no longer defined, and that header no longer includes header ‘limits.h’ from C nor ‘climits’ from C++.
[This has been postponed to 2022-08-10, after the CRAN summer shutdown.]
Support in ‘tools::Rdiff’ for uncompressed PDF files is further reduced
(see its help page): support may be removed entirely in future.
