eSpeak package links broken for Edgy?

[Jonathan Duddington]

I noticed yesterday that if I search http://packages.ubuntu.com/ for
"espeak" I see four related packages for Edgy (espeak, espeak-data,
libespeak1, libespeak-dev), all at version 1.15.

If I try now (a day later) to download these packages, the last three
give "404-Not found", while the first gives an old version, 1.11.

The new packages listed are in the database, but the files are not in
http://packages.ubuntu.com/edgy/sound.  Has the release process gone
wrong, or has the new version just not yet propagated through the
system?
