Latest Cargo Maven2 plugin?

Hello fellow cargo users...

Can anyone help me understand the correct version of cargo maven2 plugin to use?

I see the cargo website shows 0.3 version: http://cargo.codehaus.org/Home

However, when I look in the main maven repository, I see: 1.0-beta-2:  http://repo2.maven.org/maven2/org/codehaus/cargo/cargo-maven2-plugin/1.0-beta-2/

I've tried using this 1.0-beta-2 version and it seems to work well for me using a tomcat6x container.

So, what is the reason why 1.0-beta-2 is not listed on the main website, and when do you think it (or 1.0) will be released?

Thanks,
Shailesh
