NFT Protocol pushed its latest v3 contract into production on August 31st, 2022. The v3 contract is what now powers the NFT.org DEX, though existing v2 swaps and user balances can still be accessed via the UI at NFT.org.
The flagship feature addition to the v3 contract is a non-custodial swap architecture.
The following features are also included in the v3 update:
Adjustable ETH/MATIC values
Advanced accounting (DEX balances can be used on the DEX without first having to withdraw).
