 viem is designed to be as type-safe as possible! Things to keep in mind:
 
-- Types currently require using TypeScript v4.9.4 or greater.
+- Types currently require using TypeScript v5.0.4 or greater.
 - Changes to types in this repository are considered non-breaking and are usually released as patch semver changes (otherwise every type enhancement would be a major version!).
 - It is highly recommended that you lock your `viem` package version to a specific patch release and upgrade with the expectation that types may be fixed or upgraded between any release.
 - The non-type-related public API of `viem` still follows semver very strictly.
