Where can i download latest stable bitcoin-core src files? i want to download latest stable bitcoin-core src files. and want to build it on my system from source.

here is latest src of bitcoin-core but its not stable for production ready environment.

https://github.com/bitcoin/bitcoin 


https://bitcoin.org/en/download shows latest version as 

Latest version: 0.14.2




Update 1 :

Looks like git checkout is what i am looking for.
git clone git@github.com:bitcoin/bitcoin.git
git checkout tag_name


the latest version must be v0.15.0.1 now. so the command is :
git checkout v0.15.0.1
