RcppDate ships the featureful date library written by Howard Hinnant to enable use from R packages. This header-only modern C++ library has been in pretty wide-spread use for a while now, and adds to C++11, C++14 and C++17 what is (with minor modifications) the ‘date’ library in C++20. The RcppDate package adds no extra R or C++ code and can therefore be a zero-cost dependency for any other project; yet a number of other projects decided to re-vendor it resulting in less-efficient duplication. Oh well. C’est la vie.
This release syncs with upstream release 3.0.5 made yesterday. We also made two routine updates to the continuous integration since the last release a good year ago. The Debian and r2u packages for this new release have already been uploaded too.
