This blog is updated daily.
A general description is here.
‘colSums()’ and friends now have support for arrays and data-frame columns with 2^31 or more elements.
‘dnorm(x, log = FALSE)’ is more accurate (but somewhat slower) for |x| > 5; as suggested in PR#15620.
There is support to use the included (64-bit) time-zone conversion code and Olson time-zone database: use ‘configure’ option ‘--with-internal-tzcode’. This is the default on Windows and OS X.
(It might be necessary to set environment variable ‘TZ’ on OSes where this is not already set, although the system timzone is deduced correctly on at least Linux, OS X and Windows.)
The included LAPACK subset now contains ‘zgesdd’ and ‘zgelsd’.
Using ‘Sys.setlocale’ to set ‘LC_NUMERIC’ to ‘"C"’ (to restore the sane behavior) no longer gives a warning.
