The "About This Application" and "Using This Application" documents for the Mail template (Mail8.ntf) and the Contacts template (Pernames.ntf) have been updated for 8.0. However, you will not see these updated documents in applications created prior to 8.0.
The reason is that in previous releases, the templates had the "Prohibit design refresh or replace to modify" property on those design elements. Note that this was a customer requested change to the templates, back in R4. Of course, I wasn't working on Notes then, and we're not sure exactly what the use cases were for making this change.
I suspect this was because many of you customized your templates and provided customized "about" and "using" documents and you didn't want them to get stomped on. In Notes 8, we have made many changes to Mail and Contacts applications AND to the "about" and "using" documents, so now some of you might be between a bit of a rock and a hard place, because you are going to WANT the updates we made to these documents.
Now you know, so that you can plan accordingly.
Heads up regarding the "About This Application" and "Using This Application" documents
