Hey, I'm back and have another question. >_< =)
If I update from 1.6.3 to 1.6.4, there can happen? If I simply overwrite the data is still nothing changed, except that it was updated. Right?
So plugins are still installed and everything else does too?

After over writing the files, you'll need to run the Upgrader. See this for more details: http://wiki.mybb.com/index.php/Upgrading

"It is very unlikely that any changes to plugins are needed, but language packs or themes may need to be updated."
Is it necessary to 1.6.3 from 1.6.4?

It means that language packs will need to be updated and some changes to some templates will also be required, but will probably be able to be done automatically.
