This blog is updated daily.
A general description is here.
In an Rd file, use of top-level \itemize{} inside a \value{} block is incorrect and almost always gave a faulty conversion, silently. It is now detected and gives a warning.
Also, use of \code{} inside a code block such as \examples{} is an error that is now detected and warned against.
Autoflushing of stdout is turned on when Rd processing, so warnings/error are likely to appear in the right place in redirected output (such as that from R CMD check).
median.default() now also works for "numeric"-like vectors.
anova.mlm() had trouble with some designs where near-zero rows of the tranformation matrix were not removed (caught by Nils Skutara).
xspline() now respects inline par settings.
It and grid.xspline() now handle the special case of only two control points, and splines with control points that are located well outside the device (e.g., a zoomed view of a larger curve). (Both cases were giving the error "reached MAXNUMPTS").
