Welcome to the 2nd part of this little papers series. The first part covered the papers on concurrency. This time I cover core, concepts, evolution and filesystem. I decided to keep the format with grouping the papers by domain, it makes it easier to have an overview. This edition focuses on the papers of the evolution subgroup, and also features the two highlights concepts and filesystem, which are their own subgroups and have submitted each one paper in July. Last time I did not cover filesystem, but concepts, so I'm looking forward to look deeper into features coming into C++.
