- CHANGES IN R 4.0.4:
NEW FEATURES:
* File share/texmf/tex/latex/jss.cls has been updated to work with
LaTeX versions since Oct 2020.
* Unicode character width tables (as used by nchar(, type = "w"))
have been updated to Unicode 12.1 by Brodie Gaslam (PR#17781),
including many emoji.
* The internal table for iswprint (used on Windows, macOS and AIX)
has been updated to include many recent Unicode characters.
INSTALLATION on a UNIX-ALIKE:
* If an external BLAS is specified by --with-blas=foo or _via_
environment variable BLAS_LIBS is not found, this is now a
configuration error. The previous behaviour was not clear from
the documentation: it was to continue the search as if
--with-blas=yes was specified.
BUG FIXES:
* all.equal(x,y) now "sees" the two different NAs in factors,
thanks to Bill Dunlap and others in PR#17897.
* (~ NULL)[1] and similar formula subsetting now works, thanks to a
report and patch by Henrik Bengtsson in PR#17935. Additionally,
subsetting leaving an empty formula now works too, thanks to
suggestions by Suharto Anggono.
* .traceback(n) keeps source references again, as before R 4.0.0,
fixing a regression; introduced by the PR#17580, reported
including two patch proposals by Brodie Gaslam.
* unlist(plst, recursive=FALSE) no longer drops content for
pairlists with list components, thanks to the report and patch by
Suharto Anggono in PR#17950.
* iconvlist() now also works on MUSL based (Linux) systems, from a
report and patch suggestion by Wesley Chan in PR#17970.
