I've rolled up R-2.12.1.tar.gz a short while ago. This is an update release,
which fixes a number of mostly minor issues, and some consolidation within the
area of reference classes. The most serious issues were probably that we were
not catching misspelled NAMESPACE directives and not catching accidentally
unnamed switch() arguments (notice that fixing either will likely uncover errors
in preexisting code)
You can get it from
http://cran.r-project.org/src/base/R-2/R-2.12.1.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.

R News
CHANGES IN R VERSION 2.12.1:
NEW FEATURES:
? The DVI/PDF reference manual now includes the help pages for all
the standard packages: splines, stats4 and tcltk were previously
omitted (intentionally).
? <URL: http://www.rforge.net> has been added to the default set of
repositories known to setRepositories().
? xz-utils has been updated to version 5.0.0.
? reshape() now makes use of sep when forming names during
reshaping to wide format. (PR#14435)
? legend() allows the length of lines to be set by the end user
_via_ the new argument seg.len.
? New reference class utility methods copy(), field(),
getRefClass() and getClass() have been added.
? When a character value is used for the EXPR argument in switch(),
a warning is given if more than one unnamed alternative value is
given. This will become an error in R 2.13.0.
? StructTS(type = "BSM") now allows series with just two seasons.
(Reported by Birgit Erni.)
INSTALLATION:
? The PDF reference manual is now built as PDF version 1.5 with
object compression, which on platforms for which this is not the
default (notably MiKTeX) halves its size.
? Variable FCLIBS can be set during configuration, for any
additional library flags needed when linking a shared object with
the Fortran 9x compiler. (Needed with Solaris Studio 12.2.)
BUG FIXES:
? seq.int() no longer sometimes evaluates arguments twice.
(PR#14388)
? The data.frame method of format() failed if a column name was
longer than 256 bytes (the maximum length allowed for an R name).
? predict(<lm object>, type ="terms", ...) failed if both
terms and
interval were specified. (Reported by Bill Dunlap.)
Also, if se.fit = TRUE the standard errors were reported for all
terms, not just those selected by a non-null terms.
? The TRE regular expressions engine could terminate R rather than
give an error when given certain invalid regular expressions.
(PR#14398)
? cmdscale(eig = TRUE) was documented to return n-1 eigenvalues but
in fact only returned k. It now returns all n eigenvalues.
cmdscale(add = TRUE) failed to centre the return configuration
and sometimes lost the labels on the points. Its return value
was described wrongly (it is always a list and contains component
ac).
? promptClass() in package methods now works for reference classes
and gives a suitably specialized skeleton of documentation.
Also, callSuper() now works via the methods() invocation as well
as for initially specified methods.
? download.file() could leave the destination file open if the URL
was not able to be opened. (PR#14414)
? Assignment of an environment to functions or as an attribute to
other objects now works for S4 subclasses of "environment".
? Use of [[<- for S4 subclasses of "environment" generated an
infinite recursion from the method. The method has been replaced
by internal code.
? In a reference class S4 method, callSuper() now works in
initialize() methods when there is no explicit superclass method.
? ! dropped attributes such as names and dimensions from a
length-zero argument. (PR#14424)
? When list2env() created an environment it was missing a PROTECT
call and so was vulnerable to garbage collection.
? Sweave() with keep.source=TRUE dropped comments at the start and
end of code chunks. It could also fail when \SweaveInput was
combined with named chunks.
? The Fortran code used by nls(algorithm = "port") could
infinite-loop when compiled with high optimization on a modern
version of gcc, and SAFE_FFLAGS is now used to make this less
likely. (PR#14427, seen with 32-bit Windows using gcc 4.5.0 used
from R 2.12.0.)
? sapply() with default simplify = TRUE and mapply() with default
SIMPLIFY = TRUE wrongly simplified language-like results, as,
e.g., in mapply(1:2, c(3,7), FUN = function(i,j) call(':',i,j)).
? Backreferences to undefined patterns in [g]sub(pcre = TRUE) could
cause a segfault. (PR#14431)
? The format() (and hence the print()) method for class "Date"
rounded fractional dates towards zero: it now always rounds them
down.
? Reference S4 class creation could generate ambiguous inheritance
patterns under very special circumstances.
? [[<- turned S4 subclasses of "environment" into plain
environments.
? Long titles for help pages were truncated in package indices and
a few other places.
? Additional utilities now work correctly with S4 subclasses of
"environment" (rm, locking tools and active bindings).
? spec.ar() now also work for the "ols" method. (Reported by
Hans-Ruedi Kuensch.)
? The initialization of objects from S4 subclasses of
"environment"
now allocates a new environment object.
? R CMD check has more protection against (probably erroneous)
example or test output which is invalid in the current locale.
? qr.X() with column names and pivoting now also pivots the column
names. (PR#14438)
? unit.pmax() and unit.pmin() in package grid gave incorrect
results when all inputs were of length 1. (PR#14443)
? The parser for NAMESPACE files ignored misspelled directives,
rather than signalling an error. For 2.12.x a warning will be
issued, but this will be correctly reported as an error in later
releases. (Reported by Charles Berry.)
? Fix for subsetting of "raster" objects when only one of i or j
is
specified.
? grid.raster() in package grid did not accept "nativeRaster"
objects (like rasterImage() does).
? Rendering raster images in PDF output was resetting the clipping
region.
? Rendering of raster images on Cairo X11 device was wrong,
particularly when a small image was being scaled up using
interpolation.
With Cairo < 1.6, will be better than before, though still a
little clunky. With Cairo >= 1.6, should be sweet as.
? Several bugs fixed in read.DIF(): single column inputs caused
errors, cells marked as "character" could be converted to other
types, and (in Windows) copying from the clipboard failed.
