Ts-jest, a popular preprocessor for using TypeScript with Jest, released version 25.5.1 shortly after 25.5.0. While both versions share the same core functionality and dependencies like json5, mkdirp, semver, and development dependencies like jest, typescript, and various @types, subtle differences exist. Developers considering upgrading should note the slight change in unpackedSize within the dist object (172265 vs 178200), suggesting potential internal code adjustments or bug fixes. Both rely on the same peer dependencies: jest (>=25 <26) and typescript (>=3.4 <4.0).
The versions' releaseDate indicates a rapid iterative process, with 25.5.1 being published just a few days after 25.5.0. Since no dependencies appear to have been modified between the releases, the update likely contains primarily bug fixes or minor optimisations. Developers heavily relying on ts-jest in large projects should view these versions as stable and safe to use for their TypeScript testing needs with Jest. The rapid release of 25.5.1 suggests that the development team is actively maintaining the library and responding quickly to issues. These types of point releases are essential to keep your build process optimal.
