Be careful.
Following the issues I had, Bruno got in touch with me to see if we could sort it out and he could maybe learn from my issues to assist in making future updates.
It was very kind of him and I am grateful for his assistance as my level of php knowledge is minimal.
However, since the upgrade my site is not usable, so far the issues I have are, the template changed, images won't resize, Modules menu will not load, position menu will not load, the new mobile version has so many errors it won't work, payment menu won't load, stock menu is inaccessible.
MY SHOP IS NOW CLOSED until I sort this. So my best advice to all of you is not to upgrade yet, it is not ready and you will end up with a shop that is not usable. I wish I had not upgraded, the latest is not always the greatest and I think those with better php understanding than me can run ahead and beta test it, I'll be upgrading about a month after a release from now on.
