    It is interesting that when I use Chromium 46 (which is newer than Googlebot) I get warnings from Github and Google Docs about an outdated or unsupported browser, and I get plain HTML Github pages without JS. But Google uses even older browser than I. So even Google cannot cope with browser version race and keep their browsers updated although they require this from the users.

      According to that article, Googlebot is "based on Chromium 41", it doesn't actually use Chromium 41 directly, it's still a distinct, separately developed browser. The warning you're seeing is a) probably shown based on UA, and Googlebot has a very different UA to the Chromium browser b) warning users who will need to browse/actively use the site. Googlebot simply parses content, so has no use for quite a lot of the active functionality on the site. As such, it will generally not need to support all of the features used by that active functionality, just barely enough to be able to read content.

  I'm sure they don't use Chrome for Googlebot, that would be quite inefficient. My comment was about cloaking detection.
