Joshua Eichorn has posted a note about an upcoming release of phpDocumentor, version 1.4.0, and how soon it's set to arrive.

The PhpDocumentor team hopes to release the final 1.4.0 stable feature release on 7/20. If you have test-driven any of the recent pre-releases for 1.4.0 (alpha1, alpha2, RC1, RC2), please let us know any good/bad feedback you have from that experience.
