All new features compared to SushiSwap.

Interesting to note the updated license for v3, in an attempt to prevent another SushiSwap

'Uniswap v3 Core will launch under the Business Source License 1.1—effectively a time-delayed GPL-2.0-or-later license. The license limits use of the v3 source code in a commercial or production setting for up to two years, at which point it will convert to a GPL license into perpetuity'

One of the big selling points of the original uniswap was that everything was open source as opposed to bancor. I am disappointed by this.

Since the SushiSwap was anonymous fork of Uniswap, I'm wondering how they plan to prevent an another anonymous fork just by using a different license?

Honestly they probably can't prevent forks. It's more of a discouragement, since as a forker you'd be subject to being sued if they can figure out who you are.

So basically this will prevent American citizens from forking, but international folks will have free reign to fork as they wish.

Through the only avenue that licenses matter - litigation.

There's a large difference, at least compared to Uniswap V3. Read the features to see what the new version has that SushiSwap doesn't.

For the record, SushiSwap is a fork of Uniswap, so the initial features of SushiSwap was all that Uniswap had.

By now, they mainly differ in that SushiSwaps governance seems to still go forward while Uniswap has been stuck since the requirement for doing proposals is too high.

At the moment SushiSwap has virtually none of the features listed in Uni V3. Sushi is coming out with its own new features that will differ from this named BentoBox and others. Both Uni and Sushi are innovating in their own ways which is great to see
