2010 June 23 - Tiny Hidden Update

[FadedOasis]

I just tried starting TF2 and was prompted that I needed to update. So I did what I always do, I updated the server. There's no official changelog from Valve yet, but here's what the server spat out to me:

11.83% downloading /orangebox\bin\adminserver.dll
25.55% downloading /orangebox\bin\dedicated.dll
84.72% downloading /orangebox\bin\engine.dll
99.91% downloading /orangebox\bin\materialsystem.dll
100.00% downloading /orangebox\hl2\resource\gameevents.res

I guess it was a patch for CSS servers or something and had to be applied to TF2 for consistency's sake.
