This blog is updated daily.
A general description is here.
Packages ‘compiler’ and ‘parallel’ have been added to the reference index (‘refman.pdf’).
The full reference index (‘fullrefman.pdf’) was missing packages ‘compiler’ and ‘parallel’.
‘R CMD check’ now checks for ‘.C()’, ‘.Call()’, ‘.External()’ and ‘.Fortran()’ calls in other packages, and gives a warning on those found from R itself (which are not part of the API and change without notice: many will be changed for R 3.0.0).
