Quite a release!
Thanks for continued improvement in Fedora build systems - Ivy, Tycho - the future looks
better now.

>      XMvn 2.0.0 ships with a separate API module, which makes it more

>    * Class loader isolation
>  
>      XMvn 2.0.0 Core implementation is now using an isolated class
>      loader to prevent unwanted classes from polluting Maven Core or
>      user classpath.

>  * Minor features

>    * Improved logging
>  
>      XMvn logging was ported from Plexus to SLF4J.  This makes it

>      Besides that some logging messages were improved and new ones
>      were added.
>  
>    * Dependency version report
>  
>      At the end of a build XMvn can now print a dependency version
>      report, which contains information about requested and resolved
>      dependency artifact versions.
>  
>    * Improved Tycho integration
>  
>      XMvn 2.0.0 works better with Eclipse Tycho.  In particular
>      system-scoped OSGi dependencies injected by Tycho are now
>      ignored and don't cause installation failures any longer.
>  
>    * Repository filtering
>  
>      XMvn 2.0.0 improves artifact filtering for installation
>      repositories.

>    * Migration to JSR-330
