VirtueMart 2.0.24b was released earlier today. It has few very important changes from the earlier VirtueMart version to display product categories in a much better way and with better performance. As a result all our templates which has 4 level category module display features needed to be updated with the changes. We have three such templates with us and we have release the updates for all of them earlier today.

1. VP ProMart - Version 1.1a
2. VP MegaMart - Version 1.4
