This blog is updated daily..
A general description is here.
‘untar()’ has a new arguemnt ‘restore_times’ which if false (not the default) discards the times in the tarball. This is useful if they are incorrect (some tarballs submitted to CRAN have times in a local timzeone or many years in the past even though the standard required them to be in UTC).
‘replayplot()’ cannot (and will not attempt to) replay plots recorded under R < 3.0.0. It may crash the R session if an attempt is made to replay plots created in a different build of R >= 3.0.0.
Palette changes get recorded on the display list, so replaying plots (including when resizing screen devices and using ‘dev.copy()’) will work better when the palette is changed during a plot.
‘grid.prompt()’ has been removed: use ‘devAskNewPage()’ instead.
