We track all translations of our web pages on https://www.debian.org/devel/website/stats
For german you see a list of up-to-date and outdated pages on https://www.debian.org/devel/website/stats/de And you can directly see which git command will show the differences, that are not yet applied to the translation. The differences vary greatly, sometimes it's only a typo or a link update from http to https, but sometimes larger parts of text are changed, added or removed. Therefore it's not easy to decide if a translation that is a couple of git commits behind the english version should be removed or not. IMO there's no need that you look for outdated pages manually. But it seems there's a minor bug the the script that generates theses statistics (stattrans.pl), because the l10n/ddtp page is not listed. -- viele Grüße Thomas
