I've rolled up R-2.7.1.tar.gz a short while ago.
This is a maintenance release and fixes a number of mostly minor bugs
and platform issues.
Notably, the numeric interpretation of "-", "+", and
"." has reverted to
pre-2.7.0 behaviour
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-2.7.1.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 2.7.1
NEW FEATURES
o tools::texi2dvi() has a new argument 'texinputs' to allow the
TeX and bibtex input paths to be specified (even on MiKTeX).
o dev.copy2pdf() gains an 'out.type' argument to allow it to be
used with cairo_pdf() or quartz(type = "pdf").
o poly() has additional checks against user error (as in PR#11243).
o The Mac OS quartz() device draws contiguous lines much faster.
o A field containing just a sign is no longer regarded as numeric
(it was on all platforms in 2.7.0, but not on most in earlier
versions of R). Similarly, '.' is now always non-numeric.
o CITATION files are now read in Latin-1: quite a few were
failing if used in a multibyte locale such as UTF-8.
o The DESCRIPTION file of a package can specify an 'OS_type' field
as either 'unix' or 'windows' to confine installation to
that
OS type.
o HoltWinters() now uses optimize() rather than optim for
one-parameter problems which should be more reliable (PR#11469).
o axis() now respects the setting of par("xpd") when clipping.
o The 'factor' method of format() now preserves names, dims and
dimnames in the same way as for character and numeric inputs.
(PR#11512)
o read.DIF(*, transpose=TRUE) now allows to correctly read DIF files
produced by some versions of Excel.
DEPRECATED & DEFUNCT
o The use of unserialize() on character strings is deprecated:
that was a format used in R < 2.4.0.
o The use of embedded nuls in character strings is deprecated:
They will no longer be allowed in R 2.8.0.
UTILITIES
o R CMD check checks for possible check directories in the
sources -- in mid-2008 there were about 20 examples on CRAN.
o R CMD build tries harder to clean up the inst/doc directory
from the remnants of earlier builds.
It also removes any directories with extension .Rcheck, and
files .DS_Store and ._* (created by tar on Mac OS X under some
circumstances: it now sets environment variables to ask for
such files not to be created by that tar.)
BUG FIXES
o Encoding<- on NA_character_ converted it to "NA".
o Adobe Symbol was missing from the encodings in
tools::charset_to_Unicode.
o diag(matrix(x, 0, 0)) now returns a 0-length vector of the
correct mode, instead of always numeric.
o The parser sometimes accepted invalid quoted strings in a UTF-8
locale.
o plot.default(x, y) now dispatches to Axis() methods whether
y is NULL or not.
o On Mac OS X, the Cocoa Quartz window could close without warning
under certain circumstances (specific autorelease pool flush).
o Plotting symbols with separate border and fill colours (e.g.,
plot(pch = 21)) now works with transparent 'col', but opaque
or semi-transparent 'bg'. Previously, if 'col' was
transparent then 'bg' was ignored and nothing was drawn.
o file.path() did not work correctly in 2.7.0 if the components
had different encodings.
o merge() failed if there were no common columns and one of the
inputs had zero rows.
o expand.grid() failed if an input had length 0.
o match() does again truncate strings at embedded nuls (as newly
documented in 2.7.0).
o Because of a typo, 'pointsize' in png(type="cairo")
(and jpeg,
bmp, tiff) devices was being interpreted in pixels not bigpoints.
o is() was wrong for some S3 class objects with class of length
greater than one.
o undoc() / codoc() were not checking all S4 methods in some cases.
o Use of textConnection(NULL, mode="w") could segfault.
o Use of strwidth/height(units="user") (the default) is again an
error before a user coordinate system has been set on the
device, rather than giving nonsensical values (the effect of
r31367).
o Rare string width calculations in package grid were not
interpreting the string encoding correctly.
o hasMethods(f, env) {without specified 'package'} now works
better.
o A missing PROTECT could cause segfaults on string
comparisons. (PR#11421)
o str(structure(1, classID = "Pooh")) now works fine.
o A missing PROTECT could cause segfaults in if() if coercion of
the condition was required or a warning was to be given.
o plot(<table>) now uses a sensible default main title.
o validObject() called with complete=TRUE did not use inherited
validity methods for slot classes.
o Several bugs fixed in as(): the initial method lookup was not
using the table with inherited methods (so inheritance had to
be recomputed each time); coerce() should not be called
directly--it can insert invalid inherited methods; the
constructed as() methods were not retaining the function's
environment.
o influence.measures(<glm-object>) now computes the same
Cook's distance approximations as cooks.distance().
o plot(<glm>, which=5) uses more correct Cook's distance
contours;
(fix to fix to PR#9316).
o pdf() and postscript() were not working correctly in 2.7.0 with
UTF-8 encoded data in a non-UTF-8 MBCS (e.g. EUC-JP on Unix,
CJK locales on Windows).
o conformMethod(), called by setMethod(), now checks better about
argument names in wrong order. Whereas it only warns currently,
it is planned to become an error in the future.
o The predict() method for prcomp() had an incorrect check for
the number of columns of 'newdata' if the columns were not
named.
o The axis() function now distinguishes between setting "at" to
NULL or a zero-length vector, treating the latter as a request
for no ticks. This corrects the handling of the "x" parameter
to rug().
o glob2rx("*[*") now produces a correct regular expression.
o The canvas is no longer painted on copy or save in Cocoa Quartz.
o identify() in Quartz can now be terminated by either using popup
menu equivalent (Ctrl-click or second mouse button) or by pressing
the <Esc> key. The latter was documented but did not work.
o tools:::.check_package_depends() {called from 'R CMD check'} now
also works correctly when directory-name != package-name.
o Source references were sometimes off by a line.
o The quartz() parameter 'antialias' is no longer ignored.
o The Quartz device is now trying hard to remove anti-aliasing
effects for rasterized backends in plots that use adjacent,
borderless rectangles such as image().
o The srcfilecopy() function now adds a timestamp to the object it
creates.
o parse() would lose a token when run on stdin().
o socketConnection() was using internally the class "socket"
and not "sockconn", which caused a conflict with
make.socket().
(PR#11515)
o Quartz is now trying harder to find the proper font for a given
family which resolves font issues on Mac OS X 10.4. Full font
names and PostScript names can be used interchangeably. (Note,
however that italic/oblique font faces of Helvetica are not
included in the Mac OS X 10.4 system).
o qf() no longer gives NaN when one of df1 and df2 is large and
the other is infinite (including if both are infinite); it is more
accurate e.g. for qf(1e-18, 2,4).
o qbeta(-1e10, 50, 40, log.p=TRUE) no longer hangs.
o Cocoa Quartz backend autodetection of display DPI was not
correct for screens rotated by 90 or 270 degrees.
o selectMethod("coerce", .) now uses a correct default for
'useInherited', and hence no longer may mess up the method
cache.
o show() now also works on "unregistered" S3 class objects.
o formatC(*, format="fg", flag="#") is no longer
dropping trailing
zeros.
o read.table(file = stdin()) with invalid input could leave the
connection in an invalid state and hence cause a later
segfault. (PR#11627)
o read.DIF() did not obey the default 'stringsAsFactors = TRUE'.
o The 'noquote' method for c() now works correctly with three or
more arguments.
o symbol() in plotmath expressions works again with non-ASCII
input on devices that use UTF-8 for the symbol font.
