SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** The docs.kde.org page is hugely outdated. The logo is still from KDE 3, the shipped documentation seems to at least 3 years old, sometimes even 10 years: https://docs.kde.org/stable5/en/kdevelop/kdevelop/index.html Since this is, what people find when they google (how I just did) would I recommend to take this site down. I hope somebody has access to it (or can even update it with the current state of the documentation)
The current state of d.k.o is just a mirror of the KDE documentation. https://techbase.kde.org/Projects/Documentation/KDE_(health_table) Some docs are old, but some are new. https://docs.kde.org/trunk5/en/bluedevil/kcontrol/bluedevil/index.html That's the state of the art of every documentation. You can find 20-year-old man pages in your distro.
Perhaps the main page could be updated by adding a note that the docs are identical to those shipped with the relevant software, and if it is outdated, it is still the latest available. I know it still won't get much notice, but at least it shows the problem is not with the web site, but with the original documentation.
And also updating the logo.
