New version is released. You can use component upgrade page.

To disable default invoices sent by VirtueMart, see this thread:

Yes, I confirmed that with the new version product attributes are displayed now on new orders, but not on orders that already existed and had been previewed with the older version of VM Invoice. Is there a way to clear the cache so that the old orders will display the product attributes?

One last item, I use the UPS shipping extension and noticed that the shipping option selected by the shopper is NOT displayed in the order. The standard VM PDF invoice displays this.

Thanks!
