This blog is updated daily.
A general description is here.
‘is.recursive(x)’ is no longer true when ‘x’ is an external pointer, a weak reference or byte code; the first enables ‘all.equal(x,x)’ when ‘x <- getClass(.)’.
‘options(OutDec =)’ can now specify a multi-byte character, e.g., ‘options(OutDec = "\u00b7")’ in a UTF-8 locale.
‘utils::URLencode()’ was updated to use unreserved and reserved chararacters from RFC 3986, <URL: http://tools.ietf.org/html/rfc3986>, instead of RFC 1738.
Rendering of ‘\command’ in HTML has been improved: this is particularly evident on the help page for ‘INSTALL’.
