Hours after the initial blog post announcing the first release of the new package RcppAnnoy, Qiang Kou sent us a very nice pull request adding mmap support in Windows.

So a new release with Windows support is on now CRAN, and Windows binaries should be available by this evening as usual.

To recap, 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.

Courtesy of CRANberries, there is also a diffstat report for this release. More detailed information is on the RcppAnnoy page page.
