Upgrading Drupal

From the release announcement:

Upgrading from the Drupal 4.6.0 release candidate

* Copy the new sources over your existing installation and run the upgrade script.

I have replace the old sources. I'm not sure which script to run and how to run. Can any one help? I checked the site, seems it is working without running any script?

Cheers,

I have updated my homepage to drupal-4-6-0 and all is running fine, but if i search for something there are errors like:

I'm trying to upgrade from Drupal 4.3.1 to 4.6 and having the following error when running update.php.

Steps:

Following the instructions on the update.php page, I add the throttle and bootstrap fields to the system table. Then, when I click on "run the database upgrade script" it complains that the users_roles table does not exist, so I assume I must also follow the instructions to create the users_roles and locales_meta tables following the instructions under "if you upgrade from Drupal 4.4.x...".

If I try to delete a node I get the following errors:

This afternoon, I upgraded my Drupal installation to 4.6 and also upgraded event.module to the new version based on flexinode. Everything went fine during the event.module upgrade process. I did not see any SQL errors, and I can confirm that all the data that was previously stored in the old event.module scheme was transferred successfully to the flexinode tables.

The problem is that when viewing one of the upgraded event nodes, none of the extra fields are visible. I'm stumped. I've tried disabling contrib modules that could be interfering with the new event.module to no avail.
