Is there a bug for this change?
Right now the change is for all platforms, even ChromeOS.
Is that what is wanted?

Before: 42.0.2275.0 (Official Build) canary
After: 42.0.2275.0 (Official Build) canary (64-bit)

This is now similar to what is displayed in chrome://chrome
although that doesn't say "Official Build" and doesn't
show 32-bit (only 64-bit).
