As of yesterday the Chrome beta DEB package contains the 4.0 beta version from Google Chrome.
When you want to upgrade and you followed my method described earlier in this post (reply #1)
repeat all steps (1-4) up till and including the following ciode
sudo cp opt/google/chrome /opt/ -r
The last step can only be performed when Chrome is not open at the same time.
When you restart Chrome, you wll notice it is now 188.8.131.52 version
