Get excited! 0.9.3 brings lots of bug fixes to some of your most beloved issues. I think. 
Notably, this release has support for the new DNS plugin, which is a server type other than HTTP. You can use it by building Caddy with it, then running Caddy with -type=dns. (Note that builds with the DNS server type may take significantly longer, be patient.) Buy @miekg a root beer!
Also note that the (default!) behavior of the proxy directive has changed. Read the release notes for details.
A new expires plugin was published, which helps set dynamic Expires headers.
