This blog is updated daily.
A general description is here.
‘strptime()’ now accepts times such as ‘24:00’ for midnight at the end
of the day, for although these are disallowed by POSIX 1003.1-2008, ISO
8601:2004 allows them.
‘c()’, ‘unlist()’, ‘cbind()’ and ‘rbind()’ could silently overflow the maximum vector length and cause a segfault. (PR#14571)
Parsed text containing embedded newlines was printed incorrectly by as.character.srcref(). (Reported by Hadley Wickham.)
R colours are now defined to refer to the sRGB color space.
The PDF, PostScript, and Quartz graphics devices record this fact. X11 (and cairo) and Windows just assume that your screen conforms.
Rendering of raster images on cairo X11 device was wrong, particularly when a small image was being scaled up using interpolation.
With cairo < 1.6, will be better than before, though still a little clunky. With cairo >= 1.6, should be sweet as.
