Solidity team: Solidity will be split into Classic Solidity and Core Solidity

The Solidity team of the Ethereum smart contract language recently posted that the Solidity language will be split into two separate directions: Classic Solidity and Core Solidity. The current programming language of Solidity is Classic Solidity, which is in production and the compiler is very reliable, but the Solidity team still believes that the language itself is not stable. As can be seen from the 0.x version control, its latest version is 0.80.30. Classic Solidity still plans to release major updates regularly. Core Solidity is an innovation of Solidity, and its type system is built from scratch to support features such as generics, first-class functions, and algebraic data types. Core Solidity is still in the prototype stage. Solidity 1.0 will mark the level where Core Solidity has reached a stable enough level to be the default front end. The Solidity team says that one of the goals for Core Solidity is to make the transition from the current language Classic Solidity to Core Solidity as smooth as possible, and part of the plan is to bring the syntax of Classic Solidity closer to the desired end state of Core Solidity through a series of major releases, thus making the transition gradual.
