RcppAnnoy wraps the small, fast, and lightweight C++ template header library Annoy written by Erik Bernhardsson for use at Spotify. RcppAnnoy uses Rcpp Modules to offer the exact same functionality as the Python module wrapped around Annoy.
In the 0.0.3 release, I overlooked one thing: that with builds on Windows, we would also get builds against what CRAN calls R-oldrel: the previous release, which cannot turn on C++11 via the simple
CXX_STD = CXX11 declaration in
src/Makevars (and which we need because use of Boost brings in
long long which R can only cope with under C++11 …).
So this new release 0.0.4 does nothing more than add a constraint in a
Depends: R (>= 3.1.0) to avoid builds not being able to turn on C++11.
