Upgrading Drupal

I saw a post at http://drupal.org/node/62394 which was similar, but a little different from my case so I'll try a new post.

I have several Drupal sites like this :

http://site1.com
http://site2.com
..
http://siteN.com

They all separate MySQL databases (no "prefixes"), but they all share a common Drupal code base.

I have a couple contrib modules (Gsite and AdSense), and Democratica themes.

I don't think I have "primary and secondary" sites which are referred to in http://drupal.org/node/62394. I'd say all my sites are equal peers.

All the sites have their own settings.php file like this :

drupal-4.6/sites/site1.com/settings.php
drupal-4.6/sites/site2.com/settings.php
..
drupal-4.6/sites/siteN.com/settings.php

Each settings.php looks like this :

$db_url = 'mysql://drupal_site1:PASSWORD@localhost/drupal_site1_databasename';
$db_prefix = '';
$base_url = 'http://site1.com';

I read the upgrade instructions and video, but I didn't see much on mutliple site upgrades. Like the users in http://drupal.org/node/62394 I saw a blank screen after upgrade in most cases. A couple upgrades were successful, however.

It seems like you need to run update.php while logged in as user #1. This seemed impossible for multiple sites since once
you switch the code base to Drupal 4.7 you won't be able to log into other sites.

I did try running update.php with "$access" set to FALSE (forget exact variable name). This at least let me upgrade a

Where do I find release notes so that I know what changed between versions?

The issues tracking system doesn't seem to associate versions with bug fixes???

I've been working with Drupal for a year but have run into an issue with 4.7.2 and (which is where I hit it ) Views - when I run update it basically never completes.

I found other older threads but they were very technical so not sure what else people might need to know. I could find out if ask for specifics.

I just upgraded from 4.7.0 to 4.7.2 but I'm not sure that it took. Is there a way to verify what version your running or should I have seen a change from 4.7.0 to 4.7.2?

Thanks

I just 'upgraded' from 4.7.0 to 4.7.2, I think.... Is there a way to verify this? This is the first time I have tried an 'upgrade' so I'm not exactly sure if I did it right.

Thanks
