Release 0.9.9 of Rcpp
is now on CRAN and getting into
Debian too. This is mainly a bug fix release:
our addition of int64
support in 0.9.8 came at the expense of support for long and
unsigned long which broke some packages using Rcpp, and
expecting those types. Ooops.

The complete NEWS entry for 0.9.9; more details are in the ChangeLog file in the package and on the
Rcpp Changelog page.

0.9.9   2012-12-25

    o   Reverting the 'int64' changes from release 0.9.8 which adversely
        affect packages using Rcpp We will re-apply the 'int64' changes in a 
        way which should cooperate more easily with 'long' and 'unsigned long'.

    o   Unit test output directory fallback changed to use Rcpp.Rcheck

    o   Conditioned two unit tests to not run on Windows where they now break
        whereas they passed before, and continue to pass on other OSs

Thanks to
CRANberries, you can also look at a
diff to the previous release 0.9.8.
As always, even fuller details are on the
Rcpp Changelog page and the
Rcpp page which also
leads to the downloads, the
browseable
doxygen docs and zip files of doxygen output for the standard formats.
A local directory has
source and documentation too.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page
