Upgrade wordpress 2.3.1

This is a reminder for me.

I’ve upgraded my wp from 2.1 to 2.3: the new version needs some changes:

1. file index.php (template directory)

    <!-- correzione per aggiornamento wordpress 2.3.1 errore chiamata funzione in_category() in wp-includes/category-template.php -->
    <?php if ( in_category($AsideId) && !is_single() ) : ?>
    <?php if ( $AsideID != '' && in_category($AsideId) && !is_single() ) : ?>

2. file wp-config.php

    //define('DB_CHARSET', 'utf8'); // default value
    define('DB_CHARSET', 'latin1'); // update for WP 2.3.1
