I've also noticed no improvement with GoldHEN v1.1 over v1.0 on 755.
I still sometimes get a freeze when shutting down or entering rest mode. Only sometimes, but it still happens.
I think the update was maily for 7.50 and 7.51 users so thats probably why.
when I tested goldhen 1.1 on my console, it seemed to load much more quickly than previous hens. I don't know if that was just my imagination or a coincidence.
