React DOM version 19.1.0 introduces subtle yet crucial improvements over its predecessor, version 19.0.0, enhancing the performance and compatibility of React applications interacting with the Document Object Model (DOM). A key difference lies in the updated dependencies; version 19.1.0 now relies on scheduler version ^0.26.0, whereas version 19.0.0 used scheduler version ^0.25.0. This scheduler upgrade potentially brings improvements in task prioritization and overall rendering efficiency, benefiting applications with complex UI updates and interactions. Both versions share the same permissive MIT license and project repository on GitHub, ensuring developer freedom and open collaboration.
The peer dependency on React itself is also updated, with version 19.1.0 requiring react version ^19.1.0 compared to ^19.0.0 for the older version. This ensures better synchronization between the core React library and the DOM interaction layer, further minimizing potential compatibility issues and maximizing stability. Notably, the unpacked size of the package has slightly increased from 6,370,687 bytes in version 19.0.0 to 6,552,660 bytes in version 19.1.0, suggesting the inclusion of new features, optimizations or bug fixes that contribute to a more robust and efficient React DOM experience. Finally, version 19.1.0 has a late release date, 2025-03-28T19:59:53.229Z compared to 2024-12-05T18:10:30.516Z of version 19.0.0.
