This is actually (and finally) the 1.0 version. Thought link to source package is still suffixed as pre-release, no binary changes are expected and it builds itself as 1.0
There's flaws in supplementary material, like bugs and oblivions on build scripts and partly or completely insane documentation. Once these are fixed there will be the final clean source package also with distribution packages.
Prebuild packages are available on deb-based distributions below. Please note that you need both php5-scache and scached -packages.
For other unlisted debian-based systems you can rebuild packages yourself with "./debian/rules binary" from source tarball. For rpm-based distributions I have no idea how spec-files should be crafted so I make silent wish someone provides me a suitable one.
Maybe advertisement someday to pay this server.
