Purge menu item in Josm.

I have just installed JOSM 5315 on Kubuntu. There is no “purge” menu item under “edit”.
http://josm.openstreetmap.de/wiki/Help/Action/Purge indicates that there should be one.
Ctrl+Shift+P purges ok. Does anyone know where the menu item went or is it just on my installation?

I don’t know about 5315, but in 5335 it is present.

Congratulations, you are now officially a JOSM expert.

(See http://josm.openstreetmap.de/wiki/Help/ExpertMode on how to enable the corresponding mode.)

Bastik, sigh, I will NEVER be an expert. Things change too quickly for me. Many thanks for helping this amateur.
