This blog is updated daily.
A general description is here.
The unexported and undocumented Windows-only devices 'cairo_bmp()', 'cairo_png()' and 'cairo_tiff()' have been removed.
'getClass("foo")' now also returns a class definition when it is found
in the cache more than once.
'capture.output()' gets optional arguments 'type' and 'split' to pass to 'sink()', and hence can be used to capture messages.
'read.table()' now always uses the names for a named 'colClasses' argument (previously names were only used when 'colClasses' was too short). (In part, wish of PR#16478.)
'getClass("foo")' now also returns a class definition when it is found in the cache more than once.
If the 'na.action' argument was used in 'model.frame()', the original data could be modified. (PR#16436)
