Version Details and Security Vulnerabilities

postcss-prefix-selector versions 1.14.0 and 1.13.0 offer developers a straightforward solution for prefixing CSS rules with a selector, useful for namespacing styles or applying specific themes. A key difference lies in the dependency management, 1.13.0 explicitly defines postcss as a dependency, requiring a version greater than or equal to 8.3.6. Version 1.14.0 shifts this to a peer dependency allowing greater flexibility, declaring compatibility with PostCSS versions 7.x or 8.x. This signifies a broader compatibility range for developers already using PostCSS in their projects. This change allows users to avoid potential conflicts of having multiple versions of postcss installed or updating their core postcss library to use the prefix selector.

Both versions share the same core functionality, development dependencies for testing and code quality (like Mocha, Istanbul, Prettier, and lint-staged), MIT license, and repository. The author remains Jonathan Ong. Minor differences exist in the unpacked size of the packages (9862 vs. 9828) and release dates, with version 1.14.0 being released later. For developers, choosing version 1.14.0 may be preferable if they have an existing PostCSS setup and want to avoid dependency conflicts or if maintaining compatibility across different PostCSS versions is a priority. When installing 1.14.0 make sure that your project has postcss installed as well, due to the change in dependency type.
