R Portable Files

CHANGES IN R 3.3.3:

  NEW FEATURES:

    * Changes when redirection of a http:// URL to a https:// URL is
      encountered:

        * The internal methods of download.file() and url() now report
          that they cannot follow this (rather than failing silently).

        * (Unix-alike) download.file(method = "auto") (the default)
          re-tries with method = "libcurl".

        * (Unix-alike) url(method = "default") with an explicit open
          argument re-tries with method = "libcurl".  This covers many
          of the usages, e.g. readLines() with a URL argument.

  INSTALLATION on a UNIX-ALIKE:

    * The configure check for the zlib version is now robust to
      versions longer than 5 characters, including 1.2.11.

  UTILITIES:

    * Environmental variable _R_CHECK_TESTS_NLINES_ controls how R CMD
      check reports failing tests (see SS8 of the 'R Internals' manual).

  DEPRECATED AND DEFUNCT:

    * (C-level Native routine registration.)  The undocumented styles
      field of the components of R_CMethodDef and R_FortranMethodDef is
      deprecated.

  BUG FIXES:

    * vapply(x, *) now works with long vectors x.  (PR#17174)

    * isS3method("is.na.data.frame") and similar are correct now.
      (PR#17171)

    * grepRaw(<long>, <short>, fixed = TRUE) now works, thanks to a
      patch by Mikko Korpela.  (PR#17132)

    * Package installation into a library where the package exists
      _via_ symbolic link now should work wherever Sys.readlink()
      works, resolving PR#16725.

    * "Cincinnati" was missing an "n" in the precip dataset.

    * Fix buffer overflow vulnerability in pdf() when loading an
      encoding file.  Reported by Talos (TALOS-2016-0227).

    * getDLLRegisteredRoutines() now produces its warning correctly
      when multiple DLLs match, thanks to Matt Dowle's PR#17184.

    * Sys.timezone() now returns non-NA also on platforms such as
      Ubuntu 14.04.5 LTS, thanks to Mikko Korpela's PR#17186.

    * format(x) for an illegal "POSIXlt" object x no longer segfaults.

    * methods(f) now also works for f "(" or "{".

    * (Windows only) dir.create() did not check the length of the path
      to create, and so could overflow a buffer and crash R.
      (PR#17206)

    * On some systems, very small hexadecimal numbers in hex notation
      would underflow to zero.  (PR#17199)

    * pmin() and pmax() now work again for ordered factors and 0-length
      S3 classed objects, thanks to Suharto Anggono's PR#17195 and
      PR#17200.

    * bug.report() did not do any validity checking on a package's
      BugReports field.  It now ignores an empty field, removes leading
      whitespace and only attempts to open http:// and https:// URLs,
      falling back to emailing the maintainer.

    * Bandwidth selectors bw.ucv() and bw.SJ() gave incorrect answers
      or incorrectly reported an error (because of integer overflow)
      for inputs longer than 46341.  Similarly for bw.bcv() at length
      5793.

      Another possible integer overflow is checked and may result in an
      error report (rather than an incorrect result) for much longer
      inputs (millions for a smooth distribution).

    * findMethod() failed if the active signature had expanded beyond
      what a particular package used. (Example with packages XR and
      XRJulia on CRAN.)

    * qbeta() underflowed too early in some very asymmetric cases.
      (PR#17178)

    * R CMD Rd2pdf had problems with packages with non-ASCII titles in
      .Rd files (usually the titles were omitted).
