[Dovecot] subscriptions or .subscriptions?

I may have found a problem with the documentation concerning the subscriptions file. On the Dovecot web site there is a document that outlines the conversion from UW IMAP to Dovecot. The document says Dovecot's folder list is stored in ".subscriptions"

However, I have found that Dovecot's folder list is really "subscriptions" without the preceding dot. Did Dovecot version 1.0.alpha1 remove the dot from the subscriptions filename?
.subscriptions does not seem to work at all.
