Probably a wrong link, because the FPC 3.2.0 sources are from 2020. Note I do not follow Lazarus docs (poor) but the FPC doc sources are current and excellent.
https://www.freepascal.org/docs.html
I had not noticed that they were 2 different sites. Good to know... but also another fly in the ointment.
But I agree, the FPC documentation is generally of much better quality.
The Source Forge site is the only online option for LCL and LazUtils. And if they seem to be poor and out-of-date, that would be because the they are not tracking changes that have to started to appear in the CHM versions.
Also note you can build the most recent trunk doc sources yourself.
Yes, I know. I do that from time to time for LCL and LazUtils to verify/track changes being submitted to SVN. You know... it compiles so it must be alright.

But that doesn't get the HTML files rebuilt or uploaded to Source Forge. Hence... my question.
