This is the relevant part of the NEWS file



    * R CMD INSTALL and hence install.packages() gave an internal error
      installing a package called description from a tarball on a
      case-insensitive file system.

    * match(x, t) (and hence x %in% t) failed when x was of length one,
      and either character and x and t only differed in their Encoding
      or when x and t where complex with NAs or NaNs.  (PR#16885.)

    * unloadNamespace(ns) also works again when ns is a 'namespace', as
      from getNamespace().

    * rgamma(1,Inf) or rgamma(1, 0,0) no longer give NaN but the
      correct limit.

    * length(baseenv()) is correct now.

    * pretty(d, ..) for date-time d rarely failed when "halfmonth" time
      steps were tried (PR#16923) and on 'inaccurate' platforms such as
      32-bit windows or a configuration with --disable-long-double; see
      comment #15 of PR#16761.

    * In text.default(x, y, labels), the rarely(?) used default for
      labels is now correct also for the case of a 2-column matrix x
      and missing y.

    * as.factor(c(a = 1L)) preserves names() again as in R < 3.1.0.

    * strtrim(""[0], 0[0]) now works.

    * Use of Ctrl-C to terminate a reverse incremental search started
      by Ctrl-R in the readline-based Unix terminal interface is now
      supported for readline >= 6.3 (Ctrl-G always worked).  (PR#16603)

    * diff(<difftime>) now keeps the "units" attribute, as subtraction
      already did, PR#16940.
