Before you read on, please note that this release will most likely
require a reinstallation of all your packages using
as it now works without a user-facing shared library.
The biggest change in this version is that it is now effectively
headers-only. Before you wonder, there is still compiled code provided by
Rcpp for use by
packages. But this uses the function registration mechanism of
GNU R instead via
instantiation at package startup. This does make package building easier,
will remove the need to query GNU R for the
Rcpp library file in
src/Makevars when compiling, and should generally avoid building issues such
as the dreaded fails on paths with spaces still annoying users of a
There are a number of other fixes, upgrades and other extensions detailed in

Embedded R code chunks in sourceCpp are now executed within the working directory of the C++ source file.
Embedded R code chunks in sourceCpp can now be disabled.
Changes in Rcpp documentation:
The Rcpp-FAQ and Rcpp-package vignettes have been updated and expanded.
Vignettes are now typeset with grey background for code boxes.
The bibtex reference file has been update to reflexct current package versions.
Changes in Rcpp unit tests:
tests/doRUnit.Rwas rewritten following the

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.
