According to Foresight News, Polygon announced that its zkEVM mainnet test version has completed its first upgrade, called Dragon Fruit (also known as ForkID5). The Dragon Fruit upgrade includes the latest EVM opcode PUSH0, making Polygon zkEVM compatible with Solidity v0.8.21. The upgrade requires updating the Polygon.zkEVM.sol consensus contract. A 10-day time lock has been triggered, starting immediately. Dragon Fruit is expected to launch on the mainnet on September 11, and developers can now begin testing and checking the upgrade on the testnet.
