Version Details and Security Vulnerabilities

The @types/react package provides TypeScript definitions for React, enabling developers to write type-safe React code. Comparing versions 18.3.23 and 18.3.24, both share the same core dependencies: csstype (version 3.0.2 or higher) for CSS type definitions and @types/prop-types to provide types for React's PropTypes system. They also maintain the same peer dependencies (none) and license (MIT). The source code lives on the DefinitelyTyped repository on Github.

The primary difference lies in the release date and unpacked size. Version 18.3.24 was released on "2025-08-22", significantly later that version 18.3.23, "2025-05-27". The unpacked size is also slightly larger for the newer version (441579 bytes vs. 440833 bytes). This increase in size, without any declared changes in dependencies, typically suggests that updates or new features have been added to the type definitions. Likely, the later version incorporates fixes or enhancements to better represent React's components and APIs, or accommodate new features.

For developers, upgrading to the latest version (18.3.24) of @types/react is generally recommended. While the core dependencies remain the same, newer type definitions contribute to enhanced type safety, potentially preventing errors and improving code quality. The fileCount which is 17 in both versions suggests that the changes aren't related to adding new top level features, but rather to internal changes to the existing ones. When upgrading, ensure to recompile the TS codebase to catch potential discrepancies in the type definitions.
