Hi, for Debian Linux distribution, uscan tool is used to scan/watch upstream sources for new releases of software. https://manpages.debian.org/bullseye-backports/devscripts/uscan.1.en.html
This tool is used with watchfiles : defines URL for upstream tarball(s) and download it if the upstream tarball have highest version newer than the last upstream version. Is there a similar tool for OpenBSD ports ? thx, Laurent
