NO - as I said previously, headers are not updated in system updates,
just the binaries.
The binary - the OpenAL.framework that is installed in 10.4.7 is a
complete 1.1 OpenAL. The headers are not updated, so the headers are
the pre-existing 1.0 headers. Headers are updated with the release of
new versions of the developer tools - I don't know exactly when this
will be, so I can't tell you when you'll see these.
We understand that this is a confusing and less-than-ideal situation
- we are also in the process of updating the sources with the new 1.1
Oh, and the support for OAL 1.1 with 10.4.7 is NOT an unannounced
feature - its been stated clearly a couple of times both here and on
the CoreAudio API list - and on other parts of Apple's web site.

No, this is not what I "confirmed" with you - what I stated above is
what I confirmed with you.
