It's been a lot of fun trying the Duo out for a week, but it feels like I've gotten to use an extraordinarily polished prototype -- not a finished product that I'd want to buy and carry.

I've seen a lot of "AI helped me draft this issue". Yeah, well, it's not any clearer what the problem is. It's fine to use AI as a tool, but you still need to make sure that what you are posting makes any sense at all.

Jackson 3 rejected a null that my Boot 3 app had quietly turned into zero. I can see the case for the stricter default. But existing clients may rely on the old behavior. Would you preserve that contract or ask clients to change? https://youtu.be/HiPkoGTeNJc
