I just looked back in my archive, I assume you mean your mails dated 
23rd of September. Reading these mails, I conclude that neither of 
these errors change anything algorithmically. Keep in mind that the 
specification of the Vorbis algorithms is just that, a 
specification of algorithms. It's written to be easy to understand, 
not to include all the optimisations in libvorbis. So, often, 
libvorbis won't follow the spec exactly.

My guess is that Monty labelled your bug reports as not-a-bug and 
went back to work on Theora. IMHO a simple mail with a short 
explanation would have prevented this entire discussion.

Finally, keep in mind that Xiph.org isn't much more than a Free 
Software project that happens to have a meatspace version of itself 
in the form of a (non-profit!) foundation, so as to make it 
possible to have a few (one I think actually, namely Monty) 
developers working on it full-time, and to make it easier to have 
corporate contacts. Still, resources are very very scarce, and I 
think Xiph.org is doing the best it can right now.

You've contributed a bunch of fixes for the docs and I think I speak 
on behalf of everyone when I say thank you. That is the kind of 
thing this project needs to continue to grow and get better. Let's 
hope people continue to contribute and than Vorbis will become and 
remain the standard for distributing digital audio for a long time 
to come.
