Editor Version Problem?

[Shimizu]

On a couple of my maps I've seen comments that I need to update editor.
I've downloaded latest editor (quite recently) from the website; I don't see a check for update version on the editor itself.
What are you lot seeing that indicates my editor is out of date, maybe its just something I'm doing wrong?

Newest version is v439. If you didn't save your map with the newer editor, the mapmods still see the older version. You can check the version you have in the lower left corner of the editor. Updating your game doesn't update the map editor, you have to redownload the whole editor and replace it (just click replace when installing).
