The editors of Mathematical Reviews and zbMATH have finished the latest revision of the Mathematics Subject Classification, MSC2020. The official announcement is published jointly in the March 2020 issue of the Notices of the American Mathematical Society and the March 2020 issue of the Newsletter for the European Mathematical Society. The Notices version is available already online here. I will add a direct link to the version in the Newsletter when that has been posted.
A PDF version of the new classification is available here.
Please see the earlier post about the MSC2020 project.
