A general description is here.
Building badly-written vignettes which used the default device
(‘pdf(file = "Rplots.pdf")’ could leave the device open and hence the
file ‘Rplots.pdf’ could not be removed on Windows: all devices are now
closed.
In some circumstances the caret (cursor) could be positioned
incorrectly. (PR#14460)
When loading ‘Rconsole’ from disk, a spurious warning message was
sometimes shown.
In R 2.12.1, ‘system()’ sometimes passed an empty input stream to the
new process rather than allowing user input.
The internal method for ‘untar()’ does a better job of unravelling
symbolic links in the tarball (but still with many limitations).
