RxJS version 5.0.1 is a patch release following closely on the heels of the 5.0.0 release, both iterations focusing on Reactive Extensions for JavaScript, a powerful library for composing asynchronous and event-based programs using observable sequences. For developers already utilizing RxJS, upgrading from 5.0.0 to 5.0.1 should be relatively seamless, primarily addressing bug fixes and minor refinements rather than introducing breaking changes or major new features.
Both versions share the same core dependencies, including symbol-observable, ensuring continued compatibility and functionality. The extensive list of development dependencies, encompassing tools for testing, linting, building, and documentation like mocha, eslint, rollup, and esdoc, remains largely consistent, indicating a stable and well-maintained development environment.
The key difference lies in the typescript version specified in the devDependencies. While both versions utilize Typescript, version 5.0.0 has "typescript":"^2.0.6", version 5.0.1 has "typescript":"~2.0.6". This means that version 5.0.1 is compatible (~) meaning it supports patch versions, like 2.0.7, 2.0.8 etc., while version 5.0.0 is compatible (^) with new minor versions, like 2.1.0, 2.2.0, etc.
The choice between the two versions depends on your project's specific needs and risk tolerance. If you prioritize stability and minimal disruption, then version 5.0.1 is the best choice because the Typescript version is safer and only accepts patch versions instead of minor versions.
