- This update's really as light as the notes and its size make it out to be, but you can check out the new Cobblestone thumbnail here (all it boils down to is a brightness increase, moving of a spoopy scary ghost, and no console spew)

- Size is close to 20 MB

MAJOR designation was tripped due to its size of close to 425 MB. For reference, Scream Fortress IX (which was not designated MAJOR) totalled ~50 MB.

- Want to grab yourself a Tip of the Hats 2018 medal? Great news for you then, because you can still donate until 11:59 PM CDT tomorrow to get yourself one! Not only do you get an awesome in-game medal, your donation adds up to the $230K+ already raised for Camp One Step

- Localization, glorious localization! (made possible in part by contributions from Translators Like You - Thank You)

- Remember when Earbuds had value? Even though they don't anymore, its equip region has been standardized to "ears" instead of having its own special class

- We would have had just one day to go before 365 days without a MAJOR update, with the release of Jungle Inferno last year on 10/20/17

- Size is close to 425 MB - data capped users should be aware

- Valve actually did the engraving of trophies with yesterday's update, but there was a big problem with the Champion trophy. If you guessed that EliGE, Twistzz, and niko somehow won the major alongside Magisk and Xyp9x of Astralis, congratulations, you're correct! Too bad for those three, their time on the trophy is no more, [and the actual complete Astralis roster has been added to the trophy:

- SSG 08 Hand Brake: It has been hand painted with blue and white checkerboard patterns. Meant for oversteer, not parking

- MP5-SD Dirt Drop: Black streaks have been spray painted over a dark base. Dirt don't hurt… until it does
- MP9 Slide: A hydrographic pattern of orange and brown streaks has been applied. Who needs mud guards?
- M4A4 Converter: A red and black mesh hydrographic has been applied. Not so harmful after all...
- AUG Sweeper: It has been spray painted with a brown, grey, and red mesh pattern. Clear a path
- AK-47 Safety Net: An orange mesh pattern has been applied over a white base. Your loadout; now with high visibility

- Glock-18 High Beam: A blue spiral pattern has been applied to the slide. Hard to miss

- And for items in the 2018 Nuke Collection:

Rumor has it:

- In case you didn't believe Valve about stacking teammates in casual, mp_solid_teammates has been switched to 2 - have fun boosting your teammates (literally!)

- Now that the FACEIT Major has finished, the default landing page on the Watch tab has been adjusted to the global live matches tab. But if you sign up within the next 4 minutes, you get James White's Best Christmas Songs, and a watermelon signed by Dan Black for free!

- Speaking of the FACEIT Major, the in-game Champion and Finalist trophies have been updated. Inscribed into CS:GO history on the Champion trophy is Astralis and their squad, and inscribed on the Quarter-/Semi-/Finalist trophy are the names of the teams that advanced to the main event (the latter of which is awarded individually based on how far they got and named accordingly)
- If you go to a pro profile and inspect one of these trophies, you may notice a slight problem now that we're in a post-Scaleform world: you can't spin the trophy around completely to read everything on it (in Scaleform, it did so on its own), and in some situations the text on trophies can be hard to read (in Scaleform, the inspection periodically zoomed in and out)
- Here's an even bigger problem than that: can you spot what's wrong with the Champion trophy?

- This is the first time that Office has gotten an update since 5/29/15 (5/30/15 UTC), or 1223 days. The last time it was updated, it was to fix a bad nav mesh spot

- Otherwise, it's a bunch of script updates to accommodate the new FBI CT models and localization
- Oh, one other thing, not that Source 2 might be a certainty anytime soon, Source 2-style dates/times have been added to the csgo_english file

NCIX customers should be aware of an extremely serious data breach, which is a particularly dangerous situation due to the range of affected data (everything) as well as the inclusion of extremely sensitive info like SINs of former employees.

Newegg customers should also be aware of a separate data breach that affected recent purchases made between August 13th/14th through September 18th.

I really fucking hate this guy with a passion.

Rumor has it:

- Other than stability fixes for servers, it's localization made possible in part by contributions from Translators Like You - Thank You

- 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 a few months ago but weren't able to due to subscription limits, you should be able to try again successfully

- Other than the above Panorama-related changes and the addition of a missing quotation mark in Thai localization, this update basically introduces TazeIt's new Super Advanced Security System. (Wow, it's so light-weight! Feels like there's nothing inside.)

- Courtesy reminder: you have until 2:00 AM CDT/0800 BST to make your Pick'Em picks for the group stage of the FACEIT Major. Make sure you LOCK THEM IN by pressing the Update Picks button, otherwise you'll lose them

- On a tangentially related note because of a new "Counter-Strike Chat" DLC application surfacing, Steam.tv viewers can get some new CS:GO-themed Steam chat emoticons

- Team Pick'Em makes a return, but for those of you that couldn't get enough of making fantasy teams during The International 8, Fantasy Pick'Em unfortunately has not returned

- You guessed it, there is a lot of stickers and a lot of string updates in this one. Dig in and press View for your favorite stickers!

- Full-res Pick'Em Trophies, Bronze, Silver, and Gold. Spoiler alert: Doritos are back in style.

- RIP Autodesk Scaleform in CS:GO - August 21, 2012 - August 29/30, 2018

- There are several reports that Valve forgot to make @panorama_eco_mode actually work, and it seems that Valve has removed mention of it from the notes. It'll remain here as acknowledgement that it did surface, but you should notice that it's struck out

- Valve has changed competitive rank readjustment behavior for parties that have cheaters that get VACcinated. Your rank may now expire and not be displayed until you win one competitive match on top of being readjusted, as revealed in the updated in-game notification
