- [b]Pings have been expanded to take on a wheel format, similar to ones you would find in Dota 2 and/or League of Legends as well as Portal 2 co-op[/b]
- The concept of pinging was first available in the game through the Danger Zone mode, but as stated above, it's been expanded a bit further. However, if it gets a little too much for you, [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/edc31b9b2f888ba13b50890b3a2208ad054a96c3#diff-548c1817211f1942e214c5679f5ccd9fc6e8af5918bd8d06ef70b7888b48a37dL24088]you can choose to leave them fully enabled, enabled without sound, or completely disable them[/url]

- If you've been playing Competitive for a long time, you've probably experienced this situation a handful of times: a player manages to connect during warmup, but then disconnects and doesn't come back by the time the warmup timer expires even though everyone else is connected. You would expect that the match would not commence in this situation just like if they never had a successful connection at all, but after time expires, the match is still allowed to start and a team is left to fend for themselves 4v5. Scenarios like these should happen no longer [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/edc31b9b2f888ba13b50890b3a2208ad054a96c3#diff-548c1817211f1942e214c5679f5ccd9fc6e8af5918bd8d06ef70b7888b48a37dR23868]as matches will now be cancelled as one would expect them to if someone disconnects in warmup but doesn't show back up after the end of warmup[/url], and those who don't show back up will be properly assessed with an abandon

- It would appear that Trusted Mode has potentially been silently ever so slightly backed off a little bit, the description for it in the in-game settings now says [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/edc31b9b2f888ba13b50890b3a2208ad054a96c3#diff-548c1817211f1942e214c5679f5ccd9fc6e8af5918bd8d06ef70b7888b48a37dL23974]it prevents *most* 3rd party programs from interacting with the game[/url], it previously said all were blocked from interacting with it
- This is in spite of the [url=https://support.steampowered.com/kb_article.php?ref=8835-KLXV-0292&l=#whitelist]Steam Support article saying that there is no whitelist at all for "approved" programs whatsoever;[/url] but it's possible this article could change a little later on if it has indeed been slightly backed off

- In addition to what you'll experience in Premier Mode, for players in Valve-sponsored major tournaments, Valve made a small tweak and [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/edc31b9b2f888ba13b50890b3a2208ad054a96c3#diff-548c1817211f1942e214c5679f5ccd9fc6e8af5918bd8d06ef70b7888b48a37dR21078]changed "veto" nomenclature to "ban"[/url]

- Whenever the Rio major is able to happen, you'll probably notice a new [url=https://github.com/SteamDatabase/GameTracking-CSGO/commit/edc31b9b2f888ba13b50890b3a2208ad054a96c3#diff-548c1817211f1942e214c5679f5ccd9fc6e8af5918bd8d06ef70b7888b48a37dR24067]"Win Chance"[/url] guesstimate when spectating matches in-game through GOTV
