Version 0.5.1 of XMvn has just been released.
The only change in XMvn 0.5.1 is added support for Apache Maven 3.1.0
and Eclipse Aether. It will not work with Maven 3.0.x any longer.
In a minor version XMvn broke compatibility - that is intentional.
0.5.0 and 0.5.1 are functionally equivalent and the only difference is
Maven version support. O.5.0 works with Maven < 3.1.0, XMvn 0.5.1 works
with Maven >= 3.1.0.
