Hello,

When I log into the admin console (using version 2.8.6) I see the new option to upgrade to 2.9.0. In this section there are two options:

* Dump Database
* Update to Piwigo 2.9.0

What exactly does the Dump Database option do and when would you use it? I have not seen this option before.

There is also a sub-option under Dump Database labeled "Include history data (Warning: server memory limit may be exceeded)"....what does this option do exactly and when should you use it?

Just wondering how this should be used before clicking the "Update to Piwigo 2.9.0" option.

Thanks, Paul
