This blog is updated daily.
A general description is here.
The a new functions ‘mem.maxVSize()’ and ‘mem.maxMSize()’ allow the maximal size of the vector heap and the maximal number of nodes allowed in the current ‘R’ process to be queried and set.
(Not Windows nor macOS.) Package ‘tcltk’ now supports an environment variable ‘R_DONT_USE_TK’ which if set disables Tk initialization. This is intended for use to circumvent errors in loading the package, e.g. with recent Linux running under an address sanitizer.
Installation on a Unix-alike tries harder to link to the ‘pthread’ library where required (rather than relying on OpenMP to provide it: configuring with ‘--disable-openmp’ was failing on some Linux systems).
The ‘data.frame’ method for ‘print(x)’ is fast now also for large data frames ‘x’ and got an optional argument ‘max’, thanks to suggestions by Juan Telleria.
