This blog is updated daily.
A general description is here.
The workaround in headers ‘R.h’ and ‘Rmath.h’ (‘using namespace std;’) for the Oracle Developer Studio compiler is no longer needed now C++11 is required so has been removed. A couple more usages of ‘log()’ (which should have been ‘std::log()’) with an ‘int’ argument are reported on Solaris.
‘hist(<Date>, ...)’ and ‘hist(<POSIXt>, ...)’ no longer pass arguments for ‘rect()’ (such as ‘col’ and ‘density’) to ‘axis()’. (Thanks to Sebastian Meyer's PR#18171.)
