The Uniswap Foundation has announced that Uniswap v4-core (PoolManager) will soon enter the code freeze period. The v4 features will be considered as complete and no longer have new features added, rebuilt, or undergo major changes (such as removing hook permissions or how to implement dynamic fees). After the code freeze, developers will be able to implement hooks, create interfaces, implement position management with other external contracts, write production-ready code without mandatory refactoring. At the same time, after the code freeze, the core contracts will enter the audit phase, and v4 is expected to be deployed later this year.
