A general description is here.
‘dnorm(x, log=FALSE)’ is more accurate (but somewhat slower) for |x| > 5; as suggested in PR#15620.
(Windows, and as a substitute on OS X and perhaps elsewhere.) The system C function ‘strftime’ has been replaced by a more comprehensive version with closer conformance to the POSIX 2008 standard.
Using ‘Sys.setlocale’ to set ‘LC_NUMERIC’ to ‘"C"’ (to restore the sane
behavior) no longer yields a warning.
The backtick may now be escaped in strings, to allow names containing them to be constructed, e.g. ‘`\``’. (PR#15621)
Using ‘Sys.setlocale’ to set ‘LC_NUMERIC’ to ‘"C"’ (to restore the sane behavior) no longer yields a warning.
‘deparse()’ now deparses complex vectors more accurately; they will now re-parse to the original values. (PR#15534, patch based on code submitted by Alex Bertram.)
