Content Change Tracking

Hi All

Apologies if this has been answered I had a look around the forum briefly but couldnt see an answer.

Has anyone managed to come up with a way to easily track content changes to show front end users when the page H5P content was last modified.Im looking for a solution that would basicly display the last modified date in the front end so users could easily see when the most recent update was. It owuld also be great if we could display the content ID number with it, as it would make tracing errors and tracking changes into a type of version control.

Any ideas???
