Hi, I recently started working on a small gentoo utility named "euscan" (for Ebuild Upstream Scan) For those who don't know debian's uscan, it allows to scan upstream for new versions. It's used by packages.qa.debian.org (example: http://packages.qa.debian.org/p/php-net-ipv4.html ). It's available at: http://xf.iksaif.net/bordel/euscan
Currently, it uses two heuristics to find new versions, both based on SRC_URI and PV: - Directory scanning: scan directories to find files with newer version - Brute Force: generate new possible versions, and try to download files Note that it also works when only a part of the version is available in the url. I think that it would be great to have these informations on http://packages.gentoo.org/ and/or unofficial http://gentoo-portage.com/ website. We could also add the ability to browse packages by maintainer to help them see if they have any outdated package. I started this mostly to see if it was possible, and I don't know if i'll have the time to continue to work on that project, but I think gentoo really needs an automated way to detect outdated packages. This could also be a 2011 GSOC project (finishing euscan, and adding a web based interface to browse the results).
