The build system rolled up R-4.0.1.tar.gz (codename "See Things Now") this morning. The list below details the changes in this release. You can get the source code from http://cran.r-project.org/src/base/R-4/R-4.0.1.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course.

When set to true, zero-length arguments are recycled leading to character(0) after the sep-concatenation, i.e., to the empty string "" if collapse is a string and to the zero-length value character(0) when collapse = NULL. A package whose code uses this should depend on R (>= 4.0.1). * The summary(<warnings>) method now maps the counts correctly to the warning messages. BUG FIXES: * aov(frml, ...) now also works where the formula deparses to more than 500 characters, thanks to a report and patch proposal by Jan Hauffa. * Fix a dozen places (code, examples) as Sys.setlocale() returns the new rather than the previous setting. * Fix for adding two complex grid units via sum(). Thanks to Gu Zuguang for the report and Thomas Lin Pedersen for the patch. * Fix parallel::mclapply(..., mc.preschedule=FALSE) to handle raw vector results correctly. PR#17779 * Computing the base value, i.e., 2, "everywhere", now uses FLT_RADIX, as the original machar code looped indefinitely on the ppc64 architecture for the longdouble case. * In R 4.0.0, sort.list(x) when is.object(x) was true, e.g., for x <- I(letters), was accidentally using method = "radix". Consequently, e.g., merge(<data.frame>) was much slower than previously; reported in PR#17794. * plot(y ~ x, ylab = quote(y[i])) now works, as e.g., for xlab; related to PR#10525. * parallel::detect.cores(all.tests = TRUE) tries a matching OS name before the other tests (which were intended only for unknown OSes). * Parse data for raw strings is now recorded correctly.
