Valve[ KRAKOW 2017 ]
– Engraved the Krakow 2017 Champions on the in-game trophies, and adjusted the inspect animation to make engraved champions readable.

– Added commemorative graffiti.
[ MAPS ]

– Added support for Wingman game mode on Overpass.
[ SOUND ]

Rumor has it:
- The commemorative graffiti is on Inferno in pit, here's the full resolution version
- This graffiti is dedicated to Dosia's grenade toss which lead to the death of two Immortals players as a result of their bomb going off soon afterwards
- A before-and-after of the trophy icon, and translations from Translators Like You - Thank You: https://github.com/SteamDatabase/GameTracking-CSGO/commit/688c91f5495cce5fd0aab4b31984a3bd3b1ce847
