Though everyone hasn't received it yet, so, u can either wait or just follow the steps given below.
1. Just simply download this zip
2. Rename it to update.zip and push it to your internal storage.
3. Now just go to system update --> click on the menu (three dots on the top right ) --->Local Update ---> select your update.zip file.
Alternatively, you can also do this step via stock recovery.
NOTE:- This can't be done through twrp .
