A Reliable, Flexible, Fast and Powerful download engine. P.S. If you ask me, which version is the most stability, I will tell you it's not the version of 1.0.0 or 2.0.0, the most stability version must be the latest version because it is developed with github-flow, not production-flow. So please follow the latest release version and show me your PR. Here is the changelog for each version, it may help you.
