Download Google Chrome 5.0.366.2 for Windows.

A new build of the next version of Google’s open source browser is now available for download for early adopters. The release is mainly focused on fixing issues that survived past the previous build, v 5.0.360.4, offered at the end of the past month. At the same time, Anthony Laforge, from the Google Chrome team, indicates that Chrome 5.0.366.2 brings to the table an important change related to WebGL. Essentially, Google has tweaked its open source browser in order to improve the security by making WebGL run sandboxed.

Its nice that you don't need to break the security sandbox for WebGL now. But I still can't run WebGL on Windows because of no OpenGL drivers

Hopefully the ANGLE project fixes that.
