Apologies to everyone for the delay in this release. We had multiple technical issues to work out related to the new Mailman as well as some other technical issues. We've also added some new data points of interest! As always, this is a work in progress, it will continue to grow and be refined. Suggestions and ideas are always welcome! https://downloads.cppalliance.org/reports/boost_1_90_0_release_report.pdf
