Can't use the EAP tmp license key with 815

Just downloaded 815 to take a look. Installed OK, but Idea tells me the

tmp

license key given to me on the download page has already expired! Am I
missing something here?

Yes, a new key :)

If you have a 3.x license key it works with 815.
If not you have to wait for jetbrains to publish a new key.
