When a module is requiring an exact version of another module, the current log warning might be a little confusing. For example:

ERROR info.magnolia.init.MagnoliaServletContextListener : Oops, Magnolia could not be started
info.magnolia.module.model.reader.ModuleDependencyException: Module Magnolia Standard Templating Kit Demo Project (version 2.0.7) is dependent on standard-templating-kit version 2.0.7, but Magnolia Standard Templating Kit Module (version 2.0.8) is currently installed.

So maybe in this case it would be better to state that the module is expecting an exact version - the above message is a little confusing since it might not be clear why a higher version is "bad".
