[TYPO3] anything to do with database when upgrading from 4.0.4 to 4.0.6?

[Bing Du]

Hi,

I'm going to upgrade from 4.0.4 to 4.0.6.  Just want to confirm that I
only need to replace the 4.0.4 source package with the 4.0.6 one.  That's
it. No need to do anything with the database (e.g. compare, upgrade
wizard) in the install tool, right?  Only when major version changes (ex.
4.0.* -> 4.1.*) does the database need to be upgrade.

Thanks in advance,

Bing
