Solidity Team: Solidity will be split into Classic Solidity and Core Solidity.

[Solidity Team: Solidity will be split into Classic Solidity and Core Solidity] The Ethereum smart contracts language Solidity team recently announced that the Solidity language will be divided into two independent directions: Classic Solidity and Core Solidity. The current Solidity programming language is Classic Solidity, which is already in production and has a very reliable compiler, but the Solidity team still believes that the language itself is not stable, as seen from the 0.x version control, with the latest version being 0.80.30. Classic Solidity still plans to release major updates regularly. Core Solidity is an innovation of Solidity, with its type system built from the ground up to support features such as generics, first-class functions, and algebraic data types. Core Solidity is currently still in the prototype stage. Solidity 1.0 will mark Core Solidity reaching a sufficiently stable level to become the default frontend. The Solidity team stated that one of the goals for Core Solidity is to transition as smoothly as possible from the current language Classic Solidity to Core Solidity, and part of this plan is to make the syntax of Classic Solidity closer to the expected final state of Core Solidity through a series of major version releases, making the transition more gradual.
