Rumor has it:

- The matchmaking statistics mentioned by Valve above will be shown in [url=https://github.com/SteamDatabase/GameTracking-CS2/commit/e424ab85dff323adfc58b89da694c808a12a3cf9#diff-c6407972ca63f9d8d358ea904cef390438689604f83eaf6a7935d89a6e118cb1R35513]a tooltip that states[/url]: "Only %players% players are searching in your region, long wait expected." ("%players%" being substituted for the actual number of players searching)
- This tooltip will first appear with a yellow exclamation mark beside it, but if there are a critically low amount of players (such as during a recovery from a Steam usual weekly server update), it will turn red

- Aside from [url=https://github.com/SteamDatabase/GameTracking-CS2/commit/e424ab85dff323adfc58b89da694c808a12a3cf9#diff-a32627cd9fb2c637454782895f8ddeaebc43af126fb9b31dd3f6b93b9f1ed0db]a bit of Vulkan ray-tracing plumbing[/url] and another round of localization file updates (made possible in part by contributions from [url=https://valve.crowdin.com/]Translators Like You - Thank You[/url]), this update is that of a WYSIWYG nature

- Size is ~1.3 GB (with Workshop Tools installed) - data capped users should take action now
