Stable Channel Release and Beta Channel Update

Tuesday, November 6, 2012

The Chrome team is excited to announce the release of Chrome 23 to the Stable Channel. 23.0.1271.64 for Windows, Mac, Linux, and Chrome Frame. Chrome 23 contains a number of new features including GPU accelerated video decoding on Windows and easier website permissions. More detailed updates are available on the Chrome Blog.
Security fixes and rewards:

Please see the Chromium security page for more detail. Note that the referenced bugs may be kept private until a majority of our users are up to date with the fix.

Occasionally, we issue special rewards for bugs outside of Chrome, particularly where the bug is very severe and/or we are able to partially work around the issue:

[Mac OS only] [$1000] [149904] High CVE-2012-5115: Defend against wild writes in buggy graphics drivers. Credit to miaubiz.

And back to your regular scheduled rewards, including some at the new higher levels:
