DOTA2 updated on September 7^th. No new hero was added in the patch, and it just improved the function in the game. Here are the details:

UI
- Added a button to add friends inside the game.
- Fixed bug where guild invites could never show up.
- Darkened background behind buff stack numbers for better legibility on bright icons.

VISUAL
- Fixed LOD1 on Ol' Chopper Pudge hook
- Updated cloth settings and skinning Crystal Maiden, Invoker, Lina, and Rubick

How to add friends:
a. Click the “+” beside the Friends after entering the game.

b. Your Dota2 account ID will pop up. Share it with your friends, and let them enter it in the search box and click “Search” after they log in the game.

c. There is now an “Add Friend” button directly on the player’s profile.
