Valve have shipped an update which adds the long-awaited stickers for ESL One Katowice 2015 and the Pick'Em Challenge, with other small changes as well.
CS:GO was updated this past hour with the major addition being stickers for all sixteen teams participating in ESL One Katowice 2015, which runs from March 12-15.
The stickers are both a remuneration for participating teams and allow players to use them in the Pick'Em Challenge.
The Pick'Em Challenge has also been added into the client and allows players to correctly guess the winners during ESL One Katowice 2015 and advance through a series of trophies from bronze to silver to gold.
Aside from anticipatory changes for ESL One Katowice, a few changes were also made to client-side demo buffers and POV demo recording, which may fix the recent influx of corrupt demo downloads.
The full changelog can be found below:
