Subsonic Version for tomcat manager

HI there,
I'm using subsonic with tomcat 8 (Java 8 ) and I wondered viewing the manager App to deploy a new Version , why there is no Version number of subsonic.
So without version numbers from deployed webapps directed to manager, I can not deploy webapps via manager if there is an older version of subsonic.
Now I need to remove all webapp-content in ../tomcat8/webapps/subsonic to be able to deploy via the manager app.
with version numbers for the readable to the manager app it would be much easier to deploy newer versions.
