Tomcat 7: change in windows registry

[Jonatan Aguirre Kobayashi]

I installed tomcat 7.0.19 and the registry ubication of InstallPath and
Version keys changes from "HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software
Foundation\Tomcat\7.0" to "HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software
Foundation\Tomcat\7.0\Tomcat7", I need to know from which version change (my
previous version was 7.0.8).

Jonatan.
