For some reason, Chrome on iOS now adds what looks like a per-device GUID to its User-Agent string.
This would seem to be a major privacy concern. There’s more information at Stack Overflow.
However, this bug says:
The tabID is then stripped off from the user agent before the request goes over the network. Again: this tab ID is not send over the network, only the normal user agent is send.
The only place the modified user agent is visible from is navigator.userAgent.
