Gestern abend gab es ein Steamupdate für die HL1 Engine. Wichtigster Punkt ist wohl, das jetzt vac2 standardmäßig aktiviert ist. Bleibt zu hoffen ob es auch die Erwartungen erfüllt.
Die Änderungen im Einzelnen:

Half-Life 1: Engine

* Servers will default to starting up using VAC2
* Added "sv_uploadmax" cvar to limit the max size (in MB) a client can use for a custom resource (i.e spray decals)
* Added "-sport" command line option to allow you to specify the VAC2 port the server should use
* Don't allow servers to execute "alias" commands on clients (prevents an infinite loop exploit using alias commands from servers)
* Fixed S2C_CONNREJECT packet exploit causing the game to quit from any currently connected game server (found by Gavin Cotter)
* Fixed crash exploit caused by specially crafted packet triggering a crash in the resource upload code (found by Gavin Cotter)
* Fixed infinite loop in richtext/textentry control caused by large sets of spaces between words wrapping around line ends (found by Kristian Hermansen)
* Fixed possible lockup when refreshing a login ticket
* Disabled old style server queries by default.
