For IE10 MS pushed out a CTP and said this is a good build to test with. Is there a build in the Chrome dev branches that are more vetted then others. I just wouldn't want someone wasting their time posting results and someone else saying, "Duh, it's obvious that Chrome 12.0.0.12.a had Javascript loop optimization turned off, didn't you read the commit logs? Those results are no good. You should go back to Chrome 12.0.0.5.c to get one that is usable for JS testing".
Yeah, I certainly understand and appreciate the concern. I simply don't know if there's a set of specific builds for that purpose or I would have certainly included them.
It's updated so frequently I'm not sure there's a better way to get a specific build.
