Rcpp 0.12.6 arrived on CRAN a couple of days ago. The announcement is at
http://dirk.eddelbuettel.com/blog/2016/07/19#rcpp_0.12.6
and below.
One thing to note: If, and only if, you use it with outdated versions R as
old as R 3.1.* or older, you will hit compilation snag now reported three
times in GitHub issue tickets #512, #516 and #519 as well as StackOverflow
question yesterday. We missed that using NORET required R 3.2.* or later (as
we and CRAN use) and failed to add fallbacl #define -- which is now in master
on GitHub as well as in the 0.12.6.1 interim release in the RcppCore drat repo.
We are sorry for overlooking this, but then again, friends don't let friends
run R 3.1.* or older.

Rcpp 0.12.6: Rolling on
The sixth update in the 0.12.* series of Rcpp has arrived on the CRAN
network for
GNU R a few hours ago, and was just pushed to Debian. This 0.12.6 release
follows
the 0.12.0 release from late July, the 0.12.1 release in September, the
0.12.2
release in November, the 0.12.3 release in January, the 0.12.4 release in
March, and
the 0.12.5 release in May --- making it the tenth release at the steady
bi-montly
release frequency. Just like the previous release, this one is once again
more of a
refining maintenance release which addresses small bugs, nuisances or
documentation
issues without adding any major new features. That said, some nice features
(such as
caching support for sourceCpp() and friends) were added.
Rcpp has become the most popular way of enhancing GNU R with C or C++ code.
As of
today, 703 packages on CRAN depend on Rcpp for making analytical code go
faster and
further. That is up by about fourty packages from the last release in May!
Similar to the previous releases, we have contributions from first-time
committers.
Artem Klevtsov made na_omit run faster on vectors without NA values.
Otherwise, we
had many contributions from "regulars" like Kirill Mueller, James "coatless"
Balamuta and Dan Dillon as well as from fellow Rcpp Core contributors. Some
noteworthy highlights are encoding and string fixes, generally more robust
builds, a
new iterator-based approach for vectorized programming, the aforementioned
caching
for sourceCpp(), and several documentation enhancements. More details are
below.
Changes in Rcpp version 0.12.6 (2016-07-18)
* Changes in Rcpp API:
* The long long data type is used only if it is available, to avoid
compiler warnings (Kirill Müller in #488).
* The compiler is made aware that stop() never returns, to improve
code
path analysis (Kirill Müller in #487 addressing issue #486).
* String replacement was corrected (Qiang in #479 following mailing
list
bug report by Masaki Tsuda)
* Allow for UTF-8 encoding in error messages via
RCPP_USING_UTF8_ERROR_STRING macro (Qin Wenfeng in #493)
* The R function Rf_warningcall is now provided as well (as usual
without
leading Rf_) (#497 fixing #495)
* Changes in Rcpp Sugar:
* Const-ness of min and max functions has been corrected. (Dan
Dillon in PR
#478 fixing issue #477).
* Ambiguities for matrix/vector and scalar operations have been
fixed (Dan
Dillon in PR #476 fixing issue #475).
* New algorithm header using iterator-based approach for vectorized
functions (Dan in PR #481 revisiting PR #428 and addressing issue
#426,
with futher work by Kirill in PR #488 and Nathan in #503 fixing
issue
#502).
* The na_omit() function is now faster for vectors without NA
values (Artem
Klevtsov in PR #492)
* Changes in Rcpp Attributes:
* Add cacheDir argument to sourceCpp() to enable caching of shared
libraries across R sessions (JJ in #504).
* Code generation now deals correctly which packages containing a
dot in
their name (Qiang in #501 fixing #500).
* Changes in Rcpp Documentation:
* A section on default parameters was added to the Rcpp FAQ
vignette (James
Balamuta in #505 fixing #418).
* The Rcpp-attributes vignette is now mentioned more prominently in
question one of the Rcpp FAQ vignette.
* The Rcpp Quick Reference vignette received a facelift with new
sections
on Rcpp attributes and plugins begin added. (James Balamuta in
#509
fixing #484).
* The bib file was updated with respect to the recent JSS
publication for
RProtoBuf.
Thanks to CRANberries, you can also look at a diff to the previous release.
As
always, even fuller details are on the Rcpp Changelog page and the Rcpp page
which
also leads to the downloads page, 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.
