This blog is updated daily..
A general description is here.
Packages can specify in their ‘DESCRIPTION file’ a line like
to be installed on Windows with ‘--force-biarch’.
‘R CMD INSTALL’ no longer adds a namespace, and a ‘.First.lib()’ function in a package will be ignored. [The latter as from ca Dec 21.]
Packages without a ‘R’ directory and no ‘NAMESPACE’ file can still be installed.
The entry points ‘rgb2hsv’ and ‘hsv2rgb’ have been migrated to package ‘grDevices’ and so are no longer available.
On a 64-bit Windows platform with enough RAM, ‘R_alloc’ can now allocate up to just under 32GB like other 64-bit platforms.
