Version 4.19.0 of the shadow-utils project has been released. Notable changes in this release include disallowing some usernames that were previously accepted with the --badname option, and removing support for escaped newlines in configuration files. Possibly more interesting is the announcement that the project is deprecating a number of programs, hashing algorithms, and the ability to periodically expire passwords: Scientific research shows that periodic password expiration leads to predictable password patterns, and that even in a theoretical scenario where that wouldn't happen the gains in security are mathematically negligible (paper link). Modern security standards, such as NIST SP 800-63B-4 in the USA, prohibit periodic password expiration. [...] To align with these, we're deprecating the ability to periodically expire passwords. The specifics and long-term roadmap are currently being discussed, and we invite feedback from users, particularly from those in regulated environment
