Codeigniter download for production environment

[eluser]sathish_nec[/eluser]
Hi,

I would like to use codeigniter in an application. Where can I download a latest and stable release as I think there is a stable release(CI 2.1.0) in the codeigniter website. But there is a different release in the github(https://github.com/EllisLab/CodeIgniter). I am developing a commercial application and this will be used in the production environment. Please let me know which is the best place to download.
