This blog is updated daily.
A general description is here.
‘system()’ and ‘system2()’ with output redirected to a character vector
now give a warning if the command returns a non-zero error code. (This
is what a Unix-alike does as from R 2.12.0.)
‘system()’ and ‘system2()’ no longer discard output from the command to
stdout and stderr as often as they used to, and more cases of
‘system2()’ are implemented.
‘stdin’ is now flushed after echoing the input line.
The internal implementation of ‘tar()’ (package ‘utils’) is now
supported on Windows.
The MSI installer is now made by an R script, and there is now support
for 64-bit builds. (Unlike the Inno Setup installer, there are
separate MSI installers for 32- and 64-bit Windows.)
It is now built using ‘WiX 3.x’ rather than ‘WiX 2.0’. (As a result it is about 25% smaller.)
Some warning/error messages from ‘dyn.load()’ could be masked in ‘Rgui’
on Windows 7, as that OS can return messages containing carriage
returns and ‘Rgui’ does not support overwriting.
Filenames could not be specified using backslashes in ‘Sweave()’.
In R 2.12.0, ‘system(intern = TRUE)’ captured ‘stderr’ on ‘Rterm’ when
it was documented to only do so on ‘Rgui’.
‘Rgui’ in R 2.12.0 (only) did not always handle lines containing
carriage returns (‘\r’) correctly: sometimes random characters where
shown.
Since carriage returns have been supported in ‘Rgui’, the cursor positioning after outputting a line containing a carriage return had been unreliable.
