I’ve built .deb packages of lighttpd 1.5.0-SVN r1992 for Debian Sarge. They’re based off the latest packages in testing, upgraded to 1.5.0. The only thing missing is mod_mysql_vhost, as I don’t have mySQL 5.0 installed at the moment. This server already runs lighty 1.5.0, so the fact that you’re reading this page is the best proof that it works. ;)
The packages are available for download here.
(PS: I know, I know, what I should do is upgrade to Etch altogether…)
UPDATE (20070921): new release with linux-aio-sendfile support. You’ll need the libaio port too.
