I've rolled up R-1.7.1.tgz a short while ago. This is a patch version
mainly fixing up an assortment of issues (see below). Note also that
it comes with an updated set of recommended packages, fixing a couple
of nasty issues in at least foreign and nlme.
You can get it from
http://cran.us.r-project.org/src/base/R-1.7.1.tgz
or wait for it to be mirrored at a CRAN site nearer to you. Binaries
for various platforms will appear in due course.
There is also a version split for floppies.
These are the md5sums for the freshly created files, in case you wish
to check that they are uncorrupted:

For the R Core Team,

Here's the relevant part of the NEWS file:
CHANGES IN R VERSION 1.7.1
NEW FEATURES
o The help pages give appropriate references to the Blue,
White or Green books for functions based on the descriptions
of S functions given there. (E&OE)
o Function getAnywhere() can find non-exported objects, for
namespaces or registered methods.
DEPRECATED & DEFUNCT
o The (unimplemented) argument 'white' of parse() is deprecated.
o The tkfilefind demo in the tcltk library is deprecated, since
it never worked well, and apparently not at all with Tcl/Tk 8.4.
BUG FIXES
o print.table() used too much white space in some cases in 1.7.0.
o selectMethod() failed if `f' was a non-generic and
optional=TRUE, and gave a confusing error message if
optional=FALSE.
o pchisq(*, ncp) and qchisq(*, ncp) work in more cases for large ncp
or quantile and give warning or error messages otherwise.
o str(x) now also works when x is an "externalptr" (or "weakref").
o rbeta(), rf(), and rt() now support infinite parameter values;
other distributions return NaN instead of NA for such.
o Redefining a class is now safer if the new definition
generates an error (previously some invalid metadata could be
left behind).
o A number of errors are now caught in setClass() that
previously either went unchecked or waited until new() to
appear:
- classes may not contain themselves, directly or indirectly;
- classes appearing either as slots or as superclasses must
themselves be defined;
- slot names (direct or inherited) must be unique.
In related changes, prototype() now works as documented, and is the
recommended way to provide prototype objects.
o Sorting an ordered factor would return an unordered one.
This caused some trouble with panel.superpose (PR#974).
o methods() could return duplicates if a method in a namespace
was both exported and registered.
o The internal zip.unpack() could crash if more than 500 files
were to be extracted. (PR#2818)
o The "r+" and "r+b" modes of opening file connections disallowed
writing.
o library() now warns the user if the chosen package name
doesn't match the internal package name, and corrects the
error. (PR#2816)
o qr(LAPACK=TRUE) (and qr for complex arguments) might have failed
to pivot for rank-deficient inputs. (PR#2867)
o Only re-mapped symbols are exported by regex.o, to avoid
problems with embedded R on RedHat 9.
o arima() did not set transform.pars to FALSE if AR parameters
were fixed, although it claimed to.
o pnorm() was slower than necessary in the outer tails in some
cases due to a typo in the improvements from PR#699. (PR#2883)
o setGeneric() and setMethod() now catch some examples where the
generic and the method have different argument lists; the
evaluator checks for internal consistency of these argument lists.
o expand.grid(x) {the rare case of one argument} now treats factor
levels as in the typical case of two or more arguments.
o Some implicit coercions to lists could cause segfaults, e.g.
x <- matrix(nrow=20000, ncol=20); x$any <- numeric(0)
due to a PROTECT bug. (PR#2923)
o The replacement functions for colnames() and rownames() did not
work for arrays with more than two dimensions. They could
create dimnames of the form list(NULL, NULL) rather than
remove the dimnames attribute.
o termplot() gave incorrect answers with rug=TRUE or
partial=TRUE for factors whose levels were not in
lexicographical order.
o A serious performance flaw in as() computations was fixed (the
methods were not being cached properly.)
o model.frame(~1, data) always returned 1 row. (PR#2958)
o The data editor was truncating objects to 65535 rows. Pro
tem, editing objects with more than 65535 rows is an error,
and objects cannot be extended beyond that row. This restriction
will be removed in 1.8.0. (PR#2962)
o A bug could produce apparent loops in formal method selection
when inheritance was restricted (used for the as() function).
A related problem sometimes broke attaching a package that had
methods for basic functions, such as names(), used in method
selection.
o Empty expressions as in return(x,) could generate subsequent
segfaults: they are now errors. (PR#2880)
o The Kinderman-Ramage Normal Random Generator had several
problems leading to not-quite normally distributed variates
(PR#2846). One problem was traced to an error in the original
1976 JASA paper! Thanks to Josef Leydold and his team for
investigating this. The old generator has been retained for
reproducibility of older results, under the name
"Buggy Kinderman-Ramage". A warning is issued if you select it
(also indirectly via RNGversion()).
o promptMethods() now puts the \alias lines for methods in the
normal place, near the top of the file, and quotes class
names in signatures.
o getS3method() and methods() were not finding methods for
coefficients() and fitted.values() (which dispatch on "coef"
and "fitted" respectively).
o scan() (and hence read.table) was not finding matches for
separator chars with the upper bit set. (PR#3035)
o lm.(w)fit failed if the fit had rank 0.
o lqs() did not report explicitly that it had failed if all
samples gave singular fits.
o predict.lm(*, se=TRUE) {w/ weights, w/o newdata} now gives correct
SE's. (PR#3043)
o cor.test(x, y, method="spearman") now also works for
length(x) > 1290.
o Matrices were printed mis-aligned if right=TRUE and na.print
was specified. (PR#3058)
o R CMD check gives now a clearer message when latex produces
errors on the package manual. (PR#3070)
o isSeekable() was incorrectly returning FALSE on all file connections.
o tkpager() wasn't quite using its title and header arguments in
the way prescribed by file.show()
o legend(*, pch=p, lty=l) now works better when `p' or `l' have
NAs.
o All braces in regular expressions used by Sweave() are now
escaped by a backslash.
o unloadNamespace() failed because getNamespaceImports() now coerces a
string argument to a name space.
o deriv3 gave incorrect Hessians for some very simple
expressions such as expression(x*y) (since the comments in the
C code were incorrect). (PR#2577)
o power.t.test(..., delta=NULL,alternative='two.sided') failed. (PR#2993)
o Lines on postscript() plots with thousands of segments might
have been plotted inaccurately in 1.7.0. (PR#3132)
Solid lines in postscript() output are split into groups of 1000
segments to help some PostScript interpreters (typically old
level-1 interpreters).
o cut.POSIXt failed when the breaks were date/time objects. (PR#3181)
o Usage of methods in dist.Rd is now correctly documented
(as.matrix.dist() is not an exported symbol).
o The predict() method for ar fits was not retrieving the series
from the parent environment.
o eigen() and La.eigen() were not returning a matrix of
eigenvectors for a 1x1 input.
o hsv() and rgb() now return character(0) when one of their args has
length 0. This also fixes terrain.color(1). (PR#3233)
o [[<-.data.frame checked if a replacment was too short, but not
if it was too long. (related to PR#3229)
o qt(x, df) was quite inaccurate for df=1+epsilon; it is now much more
accurate for df in (1,2) and more precise for other df. (PR#2991)
o qbeta() now has slightly improved C code in two places, as suggested
in the 2nd followup to PR#2894.
