I created a roadmap project fro the c++ repo since I realized it wasn't communicated how we decided we needed a 2.0 release. We're using semantic versioning and have a bunch of major API changes that would break old code -- but that should have been more obvious to the dev list.
It might overlap a bit with the todo list project, but this should also help us describe any major new features that make it into new versions, as opposed to re-reading all the old PRs and commit messages since the previous release: https://github.com/apache/incubator-datasketches-cpp/projects/3 jon
