Varnish and Streaming questions

[Teemu Antti-Poika]

Hi all,

I'm interested in upgrading our Varnish installation to the latest and 
greatest. We serve large files and the streaming support is of interest: 
previously we've had to disable Varnish caching for huge files in order 
for our servers to be responsive.

I'm testing the release announced in November:

Is there anything I should be aware of about the release? Any known 
issues? The reason I'm asking is partly because the streaming support 
does not seem to have made it's way to the official release versions, yet.

Thanks for any observations,
Teemu Antti-Poika
