How do you view relaunching a product after just a few months?

I've been developing this product for over a year, which has led to various pivots. While keeping the same product name, the product itself has changed significantly. I'm finding lots of constraints when trying to launch on Product Hunt. For instance, when we attempted to relaunch six months ago, we were excluded from being featured due to these restrictions. I'm facing a dilemma: Should I launch with a new name or keep the existing one? Product Hunt seems to have many unwritten restrictions that make it challenging - rules that aren't clearly documented. The key question is: What's the better strategy - rebranding with a new name or maintaining our current brand identity?
