Which version to use?

[Jean-Baptiste Quenot]

Thanks for providing this great piece of software: nginx.

I'm successfully running 0.6.35 at my site with the [1]syslog patch.
Today I noticed there was several major new versions, 0.7.x and 0.8.x
and searched for a list of major changes with no luck.  I'm sticking
to 0.6.x as this is the major version provided by Debian and Ubuntu on
stable dists, but I'm looking to upgrade.

Where can I find a summary of major changes in the 0.7 and 0.8 series?
 Can you point me to a brief comparison between 0.6 and 0.7/0.8?

Thanks in advance,
