[solved] Upgrade 1.3.2 => 1.3.4

Hello.

I have a local forum and a live forum who run both under PunBB 1.3.x.  I installed them last winder for style demo after I had a style request.
On the same time, I was board admin on a paid host service for already one year.  But during the winter, the host admin have vanished and the domain expired, leaving us staff outside.  So I decided to gather them on one of my four live test boards (phpBB2, phpBB3, PunBB 1.3.2 and Connectix Boards).  The other ex-board admin chose PunBB, so we the eight refugee staff members met up on the PunBB forum and we first decided to close registration after the last of the 8 refugees registered.
Then recently, we voted to reopen the forum to new registrants, so other people we knew on other boards can join us.

And so, I switched the style back to the default one (up to now, I was using the style I made for the request) and I would like to make a new one.

But before all of that, I want to upgrade both forums (the local one and the live one - the only extension installed on both of them is the pun_repository), and since I'm two versions backwards, I have a few questions :
- Does the "changed files only" archive includes the database update script ?
- If not (for the previous question) and if I have to use the full pack, do I have to upgrade to 1.3.3, then upgrade to 1.3.4, or I just need the 1.3.4 pack ?

Thanks in advance for the answers.
