Version Details and Security Vulnerabilities

Version 4.25.0 of @typescript-eslint/eslint-plugin, a TypeScript plugin for ESLint, introduces subtle but important changes compared to the previous stable version, 4.24.0, released a week earlier. The core functionality of linting TypeScript code within ESLint remains consistent, leveraging dependencies like debug, lodash, semver, regexpp, tsutils, and functional-red-black-tree for underlying operations. The key difference lies in the updated versions of internal packages @typescript-eslint/scope-manager and @typescript-eslint/experimental-utils, both bumping from 4.24.0 to 4.25.0 to match the main package version. These updates likely contain bug fixes, performance improvements, and potentially new experimental features that impact how the plugin analyzes and reports on TypeScript code. Developers should note these internal changes, as they might affect the behavior of custom rules or configurations relying on the internal APIs exposed by these packages. While the devDependencies for development tasks and peerDependencies specifying compatible ESLint and parser versions remain unchanged, the dist object reveals a slight increase in unpackedSize from 2240813 to 2242028 bytes, indicating minor additions or alterations to the plugin's codebase.

For developers upgrading from 4.24.0, it's recommended to review the changelog for @typescript-eslint/scope-manager and @typescript-eslint/experimental-utils to understand the specific changes implemented. If custom rules are in use, thorough testing after the upgrade is advised to ensure compatibility and prevent unexpected linting errors. The update process should be straightforward via npm or yarn, and the minor version bump suggests no breaking changes are expected for most users adhering to standard configurations. Overall, version 4.25.0 refines existing capabilities rather than introducing major new features, focusing on internal package updates to enhance stability and performance.
