File Geodatabases: ArcGIS 10 versus ArcGIS 10.1

[PeterWilson]

I'm currently using ArcGIS 10 and 10.1 and I'm running into problems with my File Geodatabases. If I create a File Geodatabase in ArcGIS 10.0 and open it in ArcGIS 10.1 it does recognize it as a ArcGIS 10.0 File Godatabase as the upgrade status is greyed out. Is this a bug or is there no difference between 10 and 10.1?

There is nothing to upgrade between 10.0 and 10.1.
