In addition, we would like to thank David Levin of the Chromium development community, miaubiz, Christian Holler and Martin Barbella for working with us in the development cycle and preventing bugs from ever reaching the stable channel. Various rewards were issued.


We’d also like to call particular attention to Sergey Glazunov’s $3133.7 reward. Although the linked bug is not of critical severity, it was accompanied by a beautiful chain of lesser severity bugs which demonstrated critical impact. It deserves a more detailed write-up at a later date.
