A general description is here.
‘USE_FC_LEN_T’ will become the default: this uses the correct prototypes for Fortran BLAS/LAPACK routines called from C/C++, and requires adjustment of most such calls - see ‘Writing R Extensions’ §6.6.2. (This has been supported since R 3.6.2.)
Improved determination of the correct translation domain in non-base packages, addressing the combination of PR#18092 and PR#17998 (‘#c6’) with reports and _augmented_ patch #2904 by Suharto Anggono.
Note that ‘"R-base"’ is no longer the default domain e.g., for top-level calls to ‘gettext()’; rather translation needs explicit ‘domain = *’ specification in such cases.
