This blog is updated daily.
A general description is here.
The included LAPACK sources have been updated to version 3.12.0 and some further double-complex routines added.
‘warnings()’ now always inherits from ‘"warnings"’ as documented, now also in the case of no warnings where it previously returned ‘NULL’.
‘as.complex("1i")’ now returns ‘0 + 1i’ instead of ‘NA’ with a warning.
There are new font families for the 2014-5 URW 2.0 fonts (see ‘?pdf’) which are included in recent versions of Ghostscript. These have font widths for most Greek glyphs and a few others which were missing from the original versions (whose font families remain available for reproducibility, although Ghostscript-based viewers will render using the 2.0 versions).
