Uniswap Foundation: v4-core (PoolManager) will freeze code, expected to be deployed later this year

The Uniswap Foundation has posted that Uniswap v4-core (PoolManager) is about to enter a code freeze period. V4 features will be considered code complete, with no new features, rebuilds or major changes (such as removing hook permissions, how to implement dynamic fees). After the code freeze, developers will be able to implement hooks, create interfaces, implement position management and other external contracts, and write production-ready code without forced refactoring. At the same time, after the code freeze, the core contract will enter the review stage, and v4 is expected to be deployed later this year.
