MacPorts 2.4.2 is now out and should be available via selfupdate over rsync shortly.
Ryan, could you please mirror the tarballs and signatures from the GitHub release to distfiles.macports.org? https://github.com/macports/macports-base/releases/tag/v2.4.2 I will hold back updating the website and official announce mail until we have new .pkg installers to avoid breaking the download links. At the moment, users can still install MacPorts 2.4.1 which will then automatically update itself to version 2.4.2. Rainer
