Version 0.6.0 of XEP-0373 (OpenPGP for XMPP) has been released.

Specifies end-to-end encryption and authentication of data with the
help of OpenPGP, announcement, discovery and retrieval of public keys
and a mechanism to synchronize secret keys over multiple devices.

Fix 'to'-attribute requirements: All content elements which are signed
using OpenPGP need
      that attribute to prevent Surreptitious Forward Attacks. The
<crypt/> element does not require
      one, as the intented recipient is established by the encryption
itself. The XEP had the
      requirements for <sign/> and <crypt/> mixed up. (fs)
