Rumor has it:

- A small string update here, a HUD file rename there, but otherwise a very small set of changes: https://github.com/SteamDatabase/GameTracking/commit/cae8ece93117965f84cbb766a4a53f681fdff75a

- And an item schema update which mirrors that one string change, also combined with an earlier CS:GO item schema update: https://github.com/SteamDatabase/SteamTracking/commit/4418a3fd51256aec144687205ed87c01f7e14f2c

- On the Steam side of things, the "exfgls" attribute, which controls whether or not games are eligible to be used in Steam's Family Sharing service, was added as part of this update. As such, the game can't be used in Family Sharing anymore. If you're dependent on it for whatever reason, be aware. This was also done as part of a Dota 2 main client update last night and The Lab (Valve's VR minigame tech demo), but the exception appears to be CS:GO as though it was updated today, it didn't get excluded from Family Sharing
- One other configuration note: "verifyupdates" was added around 15 minutes after the game itself was updated. Presumably, as the name of the attribute would imply, it verifies updates as they come in for consistency

Rumor has it:

- Wondering about SlothSquadron's analysis? It'll be delayed a slight bit as he's currently on a vacation

- You may notice while testing the Dual Berettas that one gun is doing all of the firing, and IluvYOU69 of reddit says that it happens when sv_infinite_ammo is enabled. This bug (if you can call it that) appears to be quite ancient, but it's listed here so you're aware if you're looking to test it with a test/practice configuration that includes the infinite ammo command

- VPK contents diff, and script changes for the new sounds. Scroll down for those things, or click here to skip most of the irrelevant stuff as there's a lot of low level changes as well

- Item schema update which adds a bit of white space, as well as a TF2 item schema update thrown in as well because SteamTracking: https://github.com/SteamDatabase/SteamTracking/commit/4418a3fd51256aec144687205ed87c01f7e14f2c

- If you're intending on reporting issues (don't be afraid, you never know if you're not the only one!), and you happen to be on Windows 10, please make mention of whether or not you're on Redstone 1/the "Anniversary Update" as not all issues may be caused by this update itself but by Redstone 1
- Unsure of whether or not you're on Redstone 1? Search for "winver", and if "OS Version" is 1607, you're on Redstone 1. Otherwise, if it says 1511, you're still on Threshold 2

Rumor has it:

- Heavy vs. Pyro will end on August 14 at 11:59 PM PDT, or 1:59 AM CDT (on the 15th), as announced in a new news entry

- Florida LAN 2016 medal, as well as a few other changes in the item schema: https://github.com/SteamDatabase/SteamTracking/commit/8a65d3520830c6f20d98c07d064d7e8290ca8908

- HUD updates, GC protobuf updates for developers, and a VPK contents diff oh my! https://github.com/SteamDatabase/GameTracking/commit/e31f32d0e320bb928e00be9183043b72a2bc298a

Rumor has it:

- Panorama is a replacement for Autodesk's proprietary Scaleform that originally was introduced within Steam's Big Picture Mode. It's since been included as part of Dota 2's Source 2 hybridization. For info on Dota 2's implementation of Panorama, see the Valve Developer Wiki
- An added bonus of the Panorama UI system, UI changes can also be picked up by services such as SteamDB's GameTracking, making the tracking of stealth UI changes much easier

- In autobuy.txt configurations for new players after today's update, armor with a helmet and armor on its own, in that order, has been bumped to the top, leaving defuse/rescue kits at the bottom
- Existing autobuy.txt configurations should not be changed however, so if you're not a loser and you're prioritizing a defuser, you won't be rudely awakened by an explosion due to a lack of a kit

- The string that explains the premise of Prime matchmaking no longer makes any explicit reference to having enough experience as part of eligibility

- GameTracking is fusing both this CS:GO update and another large Dota 2 update, so you'll be seeing a bit of both worlds, so here's scripts, that one string change, and an overview as to what changed inside of the VPKs: https://github.com/SteamDatabase/GameTracking/commit/1dba1e462676e4b61a817353ddfb554586b36df9

The top post on "that other place with those weird aliens" is literally all about the fact that Valve needs to step their stuff up when it comes to actually taking advantage of people with high-performance systems.

TLDR: still nothing for how the hell they're going to deal with the greatly increased power of GTX 1070s, 1080s, and in the not too distant future, RX 490s.

Rumor has it:

- RIP Operation Wildfire - February 17/18, 2016 - July 15, 2016
- Wildfire was apparently supposed to end on the 13th, as indicated by this portion of a string: "The Operation Wildfire event ran from February 17th, 2016 to July 13th, 2016."

- In case you missed it, here's how the Cache graffiti will appear, plus a bonus link for integration into a wallpaper of your choosing
- Unsure as to why that spot was picked specifically? This graffiti commemorates s1mple's double no-scope AWP kills in the match between Team Liquid and Fnatic. Linked is the replay that better expresses the gravity of what had happened, if you want to watch it as it happened but from a subpar angle, head to 33:15

- Have a listen to the new bomb defuse start/finish sounds in a demonstration of a real-world scenario involving the Terrorist team planting a bomb followed by a Counter-Terrorist defusing said bomb:

https://www.youtube.com/watch?v=rAzWv8Sdru4

- Script changes, most of which involve the new sounds: https://github.com/SteamDatabase/GameTracking/commit/0d17528b55169e7628ba857987e2bb9346a46f10

- Item schema update - pretty much description changes to reflect that Wildfire is now over: https://github.com/SteamDatabase/SteamTracking/commit/21517b6eddbca7837c60dff3e35bd912be88448a

GameTracking would not be able to pierce deep enough into really small updates like this one, so all you'll see there is just steam.inf number changes: https://github.com/SteamDatabase/GameTracking/commit/902eaef646e82f4ef41d4478992719ab9c3d243b

Even if you were to go and drill into the DLLs yourself, you'd be in direct violation of the Steam Subscriber Agreement, which forbids decompiling without written permission. If you were to go ask Valve and use the "prior consent, in writing, of Valve" part, they'd have good reason to say no anyway.

If you want to go the lazy route, grab update #2 which now fixes things for you:

Adding, great find! It took quite a while longer than usual for someone to find something.

Got crashes? Pont says the solution is removing the "casualcriteria.vdf" file from the \tf\ folder. Alternatively, grab update #2 that fixes things for you.
