Helped: Version 5.5 fixed the quality regression seen in version 5.
Got in the way: Version 5 was significantly worse than 4.6 for complex tasks.
… Anecdotally we ran sonnet 4.6 for our more complex stuff and sonnet 5 was a LOT worse. 5.5 seems to have fixed it and we cut over our customer workloads. It’s strange, really.
