Rollup, the popular ES module bundler, has a new release, version 4.45.0, following closely on the heels of version 4.44.2 which was released the week before. Both versions share the same core dependencies and development dependencies, suggesting that the primary functionality of the bundler remains consistent. Notably, the peer dependency on rollup itself remains at version ^4.44.1 in both packages, indicating no breaking changes inRollup can bundle small pieces of code into something larger and more complex, like an application or a library. It does this by going through your code and linking together smaller modules, which were initially isolated. This makes your code smaller, more efficient, and easier to work with. While the vast majority of dependencies stay the same, the optional dependencies @rollup/* packages for different platforms have been bumped from 4.44.2 to 4.45.0. This change is crucial for developers targeting specific operating systems and architectures, as it may include performance enhancements or bug fixes tailored to those environments. This implies focused bug fixes and performance enhancements for platform-specific builds. Furthermore, even though both packages have the same amount of files, the new package rollup@4.45.0 is slightly bigger, with an unpacked size of 2742565 bytes, 1846 bytes bigger than the previous version, this could indicate the inclusion of additional features, improved documentation, or expanded platform support within the core Rollup library itself. The releaseDate field for the new version is "2025-07-12T05:54:54.914Z", while for the previous version is "2025-07-04T12:56:59.240Z".
