Difference Between AG v2.4.1 & v2.4.2-5130fix

Do anyone knows what the difference between Advanced Guestbook.0 v2.4.1 and and v2.4.2-5130fix, I'm getting emails to upgrade, but I don't want to.

Where are these emails coming from? The current version of the guestbook is 2.4.3 as can be seen from the scripts link on the left. If you installed it via Fantastico then odds are it's fantastico emailing you and as usual they are a version or three behind.

Updating from 2.4.1 to 2.4.3 would simply be a case of replacing your existing files except config.inc.php then running misc/db_update.php
