This blog is updated daily.
A general description is here.
The included version of PCRE has been updated to 8.33.
‘R CMD build’ (with the internal ‘tar’) checks the permissions of ‘configure’ and ‘cleanup’ files and adds execute permission to the recorded permissions for these files if needed, with a warning. This is useful on OSes and file systems which do not support execute permissions (notably, on Windows).
‘plot(hclust(), cex =)’ respects ‘cex’ again (and possibly others similarly). (Reported by Peter Langfelder.)
