This blog is updated daily.
A general description is here.
colnames(df) is now also fast for dataframes with long automatic rownames. (PR#10470)
Fortran code in packages is no longer compiled with -Wall, as
this is not done on other platforms.
The canvas used when plotting on a jpeg() or bmp() device with
a transparent background (most often by copying from a screen
device with the default transparent background) is now white
and not grey.
It seems file.access() can be unreliable both ways: that is it
can also report that access is barred when it is not.
(Seen on network file systems.) So install.packages() to a
single library no longer makes use of file.access() but checks
directory creation instead: it is still possible that you can
create a directory but not be allowed to create a .dll or .chm
file, at least under Vista.
When R_COMPLETION is set to FALSE, TAB is no longer ignored,
but advances to the next tab stop in Rterm (the pre-2.5.0
behaviour) and inserts a space in Rgui.
Saving a plot to Postscript or PDF required the font database
to have been initialized: this is now done if necessary.
Very long file or pathnames could cause a crash if opened in
the script editor. (PR#10402)
