PANews reported on October 24th that Ethereum's smart contract language, Solidity, will be split into two independent development paths: Classic Solidity and Core Solidity. Although Classic Solidity, currently in production and with a reliable compiler, has reached version 0.80.30, the team considers the language itself to be still unstable (as evidenced by the 0.x versioning). Major updates will continue to be released regularly. Core Solidity is a radically reimagined Solidity with a completely rebuilt type system that supports features such as generics, first-class functions, and algebraic data types. Currently in the prototype stage, the release of Solidity 1.0 will mark Core Solidity as stable enough to become the default frontend.

The Solidity team said that it will make the transition from Classic Solidity to Core Solidity as smooth as possible, and plans to release a series of major versions to bring the Classic Solidity syntax closer to the final state of Core Solidity, making the transition gradual.
