CHANGES IN R 3.2.1
NEW FEATURES

    utf8ToInt() now checks that its input is valid UTF-8 and returns NA if it is not.

    install.packages() now allows type = "both" with repos = NULL if \ 
it can infer the type of file.

    nchar(x, *) and nzchar(x) gain a new argument keepNA which governs how the \ 
result for NAs in x is determined. For the R 3.2.x series, the default remains \ 
FALSE which is fully back compatible. From R 3.3.0, the default will change to \ 
keepNA = NA and you are advised to consider this for code portability.

    news() more flexibly extracts dates from package ‘NEWS.Rd’ files.

    lengths(x) now also works (trivially) for atomic x and hence can be used \ 
more generally as an efficient replacement of sapply(x, length) and similar.

    The included version of PCRE has been updated to 8.37, a bug-fix release.

    diag() no longer duplicates a matrix when extracting its diagonal.

    as.character.srcref() gains an argument to allow characters corresponding to \ 
a range of source references to be extracted.

BUG FIXES

    acf() and ccf() now guarantee values strictly in [-1,1] (instead of \ 
sometimes very slightly outside). PR#15832.

    as.integer("111111111111") now gives NA (with a warning) as it \ 
does for the corresponding numeric or negative number coercions. Further, \ 
as.integer(M + 0.1) now gives M (instead of NA) when M is the maximal \ 
representable integer.

    On some platforms nchar(x, "c") and nchar(x, "w") would \ 
return values (possibly NA) for inputs which were declared to be UTF-8 but were \ 
not, or for invalid strings without a marked encoding in a multi-byte locale, \ 
rather than give an error. Additional checks have been added to mitigate this.

    apply(a, M, function(u) c(X = ., Y = .)) again has dimnames containing \ 
"X" and "Y" (as in R < 3.2.0).

    (Windows only) In some cases, the --clean option to R CMD INSTALL could \ 
fail. (PR#16178)

    (Windows only) choose.files() would occasionally include characters from the \ 
result of an earlier call in the result of a later one. (PR#16270)

    A change in RSiteSearch() in R 3.2.0 caused it to submit invalid URLs. (PR#16329)

    Rscript and command line R silently ignored incomplete statements at the end \ 
of a script; now they are reported as parse errors. (PR#16350)

    Parse data for very long strings was not stored. (PR#16354)

    plotNode(), the workhorse of the plot method for "dendrogram"s is \ 
no longer recursive, thanks to Suharto Anggono, and hence also works for deeply \ 
nested dendrograms. (PR#15215)

    The parser could overflow internally when given numbers in scientific format \ 
with extremely large exponents. (PR#16358)

    If the CRAN mirror was not set, install.packages(type = "both") \ 
and related functions could repeatedly query the user for it. (Part of PR#16362)

    The low-level functions .rowSums() etc. did not check the length of their \ 
argument, so could segfault. (PR#16367)

    The quietly argument of library() is now correctly propagated from \ 
.getRequiredPackages2().

    Under some circumstances using the internal PCRE when building R fron source \ 
would cause external libs such as -llzma to be omitted from the main link.

    The .Primitive default methods of the logic operators, i.e., !, & and |, \ 
now give correct error messages when appropriate, e.g., for `&`(TRUE) or \ 
`!`(). (PR#16385)

    cummax(x) now correctly propagates NAs also when x is of type integer and \ 
begins with an NA.

    summaryRprof() could fail when the profile contained only two records. (PR#16395)

    HTML vignettes opened using vignette() did not support links into the rest \ 
of the HTML help system. (Links worked properly when the vignette was opened \ 
using browseVignettes() or from within the help system.)

    arima(*, xreg = .) (for d >= 1) computes estimated variances based on a \ 
the number of effective observations as in R version 3.0.1 and earlier. \ 
(PR#16278)

    slotNames(.) is now correct for "signature" objects (mostly used \ 
internally in methods).

    On some systems, the first string comparison after a locale change would \ 
result in NA.
