On https://logback.qos.ch/reasonsToSwitch.html you state "Logback ships with detailed and constantly updated documentation.", but even that page itself is outdated. And besides that on https://logback.qos.ch/documentation.html alone there is a huge amount of dead or bad links. I clicked 5 links. 1 worked, 3 were dead and 1 lead to a scum page with history manipulation loop from which you have a hard time to come back except with closing the tab and re-opening the page you were at.

Also "Automatic reloading of configuration files" is not an up-to-date argument, as log4j supports this the same. Maybe not in milliseconds range, but who needs that.

Which other points are also not valid anymore? (serious question)

Maybe you should specify from when this information is respectively against what log4j version this compares.
