I've rolled up R-2.5.1.tar.gz a short while ago. This is a maintenance
release and fixes a number of mostly minor bugs and platform issues. See
the full list of changes below.
You can get it (in a short while) from
http://cran.r-project.org/src/base/R-2/R-2.5.1.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.

Here is the relevant bit of the NEWS file:
CHANGES IN R VERSION 2.5.1
NEW FEATURES
o density(1:20, bw = "SJ") now works as bw.SJ() now tries a
larger
search interval than the default (lower, upper) if it does not
find a solution within the latter.
o The output of library() (no arguments) is now sorted by library
trees in the order of .libPaths() and not alphabetically.
o R_LIBS_USER and R_LIBS_SITE feature possible expansion of
specifiers for R version specific information as part of the
startup process.
o C-level warning calls now print a more informative context,
as C-level errors have for a while.
o There is a new option "rl_word_breaks" to control the way the
input line is tokenized in the readline-based terminal
interface for object- and file-name completion.
This allows it to be tuned for people who use their space bar
vs those who do not. The default now allows filename-completion
with +-* in the filenames.
o If the srcfile argument to parse() is not NULL, it will be added
to the result as a "srcfile" attribute.
o It is no longer possible to interrupt lazy-loading (which was
only at all likely when lazy-loading environments), which
would leave the object being loaded in an unusable state.
This is a temporary measure: error-recovery when evaluating
promises will be tackled more comprehensively in 2.6.0.
INSTALLATION
o 'make check' will work with --without-iconv, to accommodate
building on AIX where the system iconv conflicts with
libiconv and is not compatible with R's requirements.
o There is support for 'DESTDIR': see the R-admin manual.
o The texinfo manuals are now converted to HTML with a style
sheet: in recent versions of makeinfo the markup such as @file
was being lost in the HTML rendering.
o The use of inlining has been tweaked to avoid warnings from
gcc >= 4.2.0 when compiling in C99 mode (which is the default
from configure).
BUG FIXES
o as.dendrogram() failed on objects of class "dendrogram".
o plot(type ="s") (or "S") with many (hundreds of
thousands)
of points could overflow the stack. (PR#9629)
o Coercing an S4 classed object to "matrix" (or other basic
class)
failed to unset the S4 bit.
o The 'useS4' argument of print.default() had been broken by an
unrelated change prior to 2.4.1. This allowed print() and
show() to bounce badly constructed S4 objects between
themselves indefinitely.
o Prediction of the seasonal component in HoltWinters() was one
step out at one point in the calculations.
decompose() incorrectly computed the 'random' component for a
multiplicative fit.
o Wildcards work again in unlink() on Unix-alikes (they did not
in 2.5.0).
o When qr() used pivoting, the coefficient names in qr.coef() were
not pivoted to match. (PR#9623)
o UseMethod() could crash R if the first argument was not a
character string.
o R and Rscript on Unix-alikes were not accepting spaces in -e
arguments (even if quoted).
o Hexadecimal integer constants (e.g. 0x10L) were not being parsed
correctly on platforms where the C function atof did not
accept hexadecimal prefixes (as required by C99, but not
implemented in MinGW as used by R on Windows). (PR#9648)
o libRlapack.dylib on Mac OS X had no version information and
sometimes an invalid identification name.
o Rd conversion of \usage treated '\\' as a single backslash in
all but latex: it now acts consistently with the other
verbatim-like environments (it was never 'verbatim' despite
the documentation).
\code{\.} is now rendered as '\.' in all formats, as
documented (it was not the case for latex conversion).
codoc() (and checkDocStyle() and checkDocUsage()) now apply
the same transformations to \usage as Rd conversion does,
so {, % and \\ in strings in usages will now be related
correctly to the help files.
o rbind() failed if the only data frame had 0 rows. (PR#9657)
o <a data.frame>[i, j] could sometimes select the wrong column
when j is numeric if there are duplicate column names.
o sample(x, size, replace=TRUE, prob) had a memory leak if
10000 < size <= 100000.
o x <- cbind(1:2); rownames(x) <- factor(c("A",NA)) now
longer
segfaults.
o R CMD BATCH no longer assumes Sys.unsetenv() is supported (it
is not on older Solaris systems).
o median() returned a logical result when it was 'NA': it now
returns an NA of appropriate type (e.g. integer or double).
o grep(fixed = TRUE, perl = TRUE) ignored 'fixed', although it
was documented to ignore 'perl'
Same for [g]regexpr and [g]sub.
o getNamespaceExports("base") works again.
o runmed(c(), 1) no longer segfaults.
o qr.coef(QR, b) failed for an LAPACK-produced QR if b was
integer or for an over-determined system.
qr.solve() for an under-determined system produces a
solution with 0 and not NA for columns which are unused.
o segments() was not handling full transparency correctly in PDF.
(PR#9694)
Nor was arrows().
o callGeneric() inside a method with extra arguments {and hence
currently defined via .local()} now works.
o [g]sub(fixed=TRUE, useBytes=FALSE) could substitute in the
wrong place in an MBCS locale.
gregexpr() could give incorrect answers in MBCS locales for
perl = TRUE or fixed = TRUE (unless useBytes = TRUE).
o The legacy quartz() device no longer crashes in locator()
if the user attempts to close the window.
o "CGGStackRestore: gstack underflow" warning is no longer shown
in legacy quartz() device.
o formatC() now limits 'digits' to 50 to avoid problems in
C-level sprintf in some OSes.
o seq.int(x, y, by=z) gave 'x' (and not an error) if
0 > (y-x)/z > -1.
o promptClass() now lists methods, including those for generics in
other attached packages.
o Connection-related functions such as readBin() no longer crash
when supplied with a non-connection object.
o as.character.srcref() didn't handle bad srcref objects cleanly.
o predict.nls() no longer requires 'newdata' to contain exactly
the variable names needed to fit the model: variables used on
the LHS only are no longer required and further variables are
allowed.
o plot.hclust() had a 'out by one' error, and ignored the last
object when computing the window region (and could overrun
arrays).
o deriv() was creating results with double (and not integer) dims.
o The unserialize code (e.g. as called by load()) looked for a
function findPackageEnv() to set a saved package environment.
This was missing, but is now supplied.
o [cr]bind could segfault when creating a list matrix result.
(Reported by Martin Morgan.)
o besselI(x, nu, exp=TRUE) and besselY(x, nu) could give wrong
answers for nu < 0. (Reported by Hiroyuki Kawakatsu.)
o [g]sub could confuse a trailing byte '\' for a backreference
in MBCSs where '\' can occur as a trailing byte (not UTF-8 nor
EUC-JP, but SJIS and the CJK character sets used on Windows).
(PR#9751)
