Sass version 1.49.1 is a minor release following version 1.49.0, both being pure JavaScript implementations of the popular Sass stylesheet language. Examining the metadata reveals minimal differences, primarily in the release date and unpacked size of the distribution. Version 1.49.1 was published on January 31, 2022, while 1.49.0 was released on January 18, 2022. The unpacked size of 1.49.1 is slightly larger at 4,460,111 bytes compared to 4,460,110 bytes for 1.49.0, suggesting very small internal adjustments or bug fixes.
Both versions share the same core dependencies, relying on "chokidar" for file system monitoring, "immutable" for persistent data structures, and "source-map-js" for source map generation. This indicates that the fundamental API and core functionalities remain consistent between the two versions. For developers using Sass, this means upgrading from 1.49.0 to 1.49.1 should be a straightforward process with minimal risk of breaking changes. Given the extremely slight difference in unpacked size and the short interval between releases, version 1.49.1 likely addresses minor edge cases or includes very targeted bug fixes identified shortly after the release of 1.49.0. For new projects, using the latest 1.49.1 is advisable, while existing projects using 1.49.0 can likely upgrade without significant code modifications or testing overhead.
