Version 4.26.1 of @typescript-eslint/parser, an ESLint custom parser leveraging TypeScript ESTree, represents a minor update from version 4.26.0, released approximately one week prior. While the core functionality remains consistent, the key differences lie in internal dependencies and overall package size.
Specifically, the dependencies @typescript-eslint/types, @typescript-eslint/scope-manager, and @typescript-eslint/typescript-estree have been updated from version 4.26.0 to 4.26.1. Similarly, the devDependency @typescript-eslint/experimental-utils also sees a bump to 4.26.1. Developers should investigate the changelogs for these dependent packages to understand the precise changes introduced, as these might include bug fixes, performance improvements, or added features relevant to their specific use cases.
Interestingly, the unpacked size of the package has slightly increased from 64371 bytes in 4.26.0 to 64550 bytes in 4.26.1. This suggests that the updates, while seemingly minor version-wise, involved code additions or adjustments impacting the overall footprint.
For developers already using @typescript-eslint/parser, upgrading to 4.26.1 offers the potential for enhanced stability and performance inherited from the dependency updates. Before upgrading, reviewing the changelogs of the updated dependencies is highly recommended to identify any breaking changes or impactful modifications that might necessitate code adjustments in their projects. Otherwise, the upgrade should be seamless, continuing to provide robust TypeScript parsing capabilities for ESLint. Finally consider that the release date can have some impact and probably influence some users to move to the newest one.
