Rumor has it:

- Here's the Katowice 2019 Danger Zone Showmatch graffiti, commemorating AGO's Furlan and GruBy's win adjacent to the spot where Furlan won the showmatch on the roofs of Tourist:

- The in-game major championship trophies have been fixed, the IEM Katowice 2019 part is no longer cut off at the top, and the inspection view has been moved up a bit so that it's no longer obscured by the description

- Now that they're fixed, this is the Champion trophy, inscribing Astralis' 3rd major win into CS:GO history. As well, this is the Quarter-/Semi-/Finalist trophy, handed out to teams that qualified for the main event and awarded based on their performance
- Distribution to pro players hasn't happened yet but it should within a short while!

- Sales of IEM Katowice 2019 items are still not done in yet, even after 4 days since the tournament's conclusion and even after graffiti was made unusable in yesterday's update

- Otherwise, it's purely a maps update: https://github.com/SteamDatabase/GameTracking-CSGO/commit/229d58e1e8fb66a4bdbf0b9dfe7f15f70e41ae88

Rumor has it:

- Here is the in-game Champion trophy as well as the Quarter-/Semi-/Finalist trophy with some new names as well as some familiar names
- There are a couple of cosmetic issues however, the first one being that the IEM Katowice 2019 ring is partially cut off due to a vtf spacing error. The second issue is that all in-game major trophies' descriptions now obscure the Katowice 2019 ring
- One small unmentioned fix about the in-game Quarterfinalist/Semifinalist/Finalist and Champion trophies did happen, when inspecting them, you can now spin them around all the way (previously immediately after the switch from legacy Scaleform to Panorama, you could only spin it 30 degrees either way)

- Though your IEM Katowice 2019 graffiti can no longer be used, you can still buy stickers and capsules...at least for now. The next time the GC is restarted however, that probably won't be the case anymore, so consider this your very last chance to stock up on some dirt cheap stickers

- Other than the above things in the notes, there's also some localization file updates which are made possible in part by contributions from Translators Like You - Thank You: https://github.com/SteamDatabase/GameTracking-CSGO/commit/c513c7dee12349d4f38f0686133dabe89482ce50

- Not necessarily directly related to this update, but remember when Danger Zone was released that Valve appeared to be using Google's Cloud Platform to host some Steam Datagram system infrastructure in Helsinki and Sao Paulo? Recent Steam Datagram system configuration changes (which have also been locally synced) indicate that Valve has given up on that project at least for right now

Rumor has it:

- With a bit over 24 hours to go before the first phase of Pick'Em locks, there continues to remain no way to directly gift an IEM Katowice 2019 Viewer Pass to a Steam friend, be it in-game or through the Steam store

- Other than the above listed changes and other last-minute preparations like the addition of the IEM Katowice logo for GOTV and a few new strings for the Watch tab, the rest of the update consists of localization file updates, which are made possible in part by contributions from Translators Like You - Thank You

Via the new csgo_servers:

Rumor has it:

- There is also a small set of translations in Spanish (including Latin American Spanish), Russian, Portuguese, Norwegian, Finnish, Italian, and Thai, made possible in part by contributions from Translators Like You - Thank You: https://github.com/SteamDatabase/GameTracking-CSGO/commit/576f294490f2d9402df825930093312c19ae50df

- Wait, what, the new csgo_servers? If you missed the email Valve sent you, they've tossed out their self-hosted GNU Mailman box that the csgo_servers mailing list was on (and the HLDS lists for TF2 and CS:S users), in favor of a cloud provider (Simplelists). If you were previously a subscriber to the old list, you must resubscribe to csgo_servers to continue getting messages
- If you tried to sign up in the first hour or so when the switch happened several months ago but weren't able to due to subscription limits, you should be able to try again successfully

- Not necessarily a part of this update, but you may wanna know that the IEM Katowice 2019 Viewer Pass can now be bought on the Steam store
- Unfortunately, "add to cart" does not add it to your cart, you'll be taken straight to checkout right away, which means there remains no option for those of you that want to gift one to a friend without needing to wait for the 7 day trade restriction after purchase to expire
