> The new version of iPOJO contains several changes : 
>  - Differentiation between component and component instances  
> Now, the declaration of a component does not create a component instance, you need to
add an instance tag with your component instance configuration:
> - Factory
> iPOJO 0.7.0-SNAPSHOT provides a factory systems. Indeed, for each declared component
type, iPOJO could expose an iPOJO factory service and a
> ManagedServiceFactory service. These two services allow the creation of component instance
dynamically. It is possible to configure these component instances. Moreover the given configuration
can contain "complex" object like Map....
> - Configuration Handler
> The configuration handler was re-implemented to be more consistent with the OSGi specification.
Moreover, the metadata, to configure the handler, changes. Henceforth, the metadata looks
like:
> <properties configurable="true">
> <property name="int" field="foo"/>
> <property name="int" field="bar"/>
> </properties>
> The configurable attribute allows the publication of the "ManagedService" service (dynamic
reconfiguration of the component instance)
> - Performance improvement :
> The iPOJO core was patched to avoid useless handler indirection.
> - Filtered service dependency :
> The dependency handler had bugs when managing dependency with a filter. This bug was
corrected. Now, the dynamism of filtered dependency works.
> - Import / Export of the "org.osgi.service.cm" package :
> The previous version of iPOJO does not export correctly the package (bad version number).
