This blog is updated daily.
A general description is here.
There is a new ‘antialias’ argument to ‘windows()’, ‘win.print()’ and
the bitmap devices. This is an option that can be set in
‘windows.options()’ to set the default for ‘windows()’ (and
‘win.graph()’).
This effectively gives a hint to the Windows plotting system. Whether anti-aliasing is used principally depends on the OS settings: this argument should at least be able to turn it off. The default behaviour (unchanged from before) is that Windows will use anti-aliasing for screen devices (and bitmap devices, as they plot on a hidden screen) if ClearType has been enabled.
The argument can also be used for the cairographics-based versions of the bitmap devices.

The default behaviour (unchanged from before) is that Windows will use anti-aliasing for screen devices (and bitmap devices, as they plot on a hidden screen) if ClearType has been enabled. For those not using ClearType, ‘windows.options(antialias="cleartype")’ will make this the default, and it will probably give more legible plots.
