I have installed 5.0.4 (build 521). The bug is still here: The keyword "end" (and also the keyword "begin") is not recognized by the Highlighter, thought the statusline says that the Ruby highlighter is active. You can see a screenshot here:
https://ibb.co/84nhk3p As for the way I did the installation: Since the instructions say that I have to unpack the 5.0.4 zip file over an existing installation, I first copied my 5.0.3 installation over to a new directory, and extracted the 5.0.4 file into this directory, then startet pspad. I have made a backup of the configuration (zip file). I don't know whether this includes the highlighter settings, but if it does, I could send it to you so you can reproduce the problem. -- Ronald Fischer (Germany) <https://forum.pspad.com/read.php?2,74086,74133> PSPad freeware editor https://www.pspad.com
