See if we can isolate the IE technical preview

[Eric Mill]

We have to whitelist individual browsers and versions, so to keep on top of IE we'll want to proactively whitelist "12", "13", "14", etc. I think the Technical Preview will be "TP", but it's not unlikely we'll find an example already in the analytics.

Here's a custom segment that isolates user agent for Microsoft Edge
AFAIK Microsoft isn't surfacing browser to prevent targeted workarounds à la IE.
For reference, the custom seg includes Operating System Version = NT and Browser Version = 42.0.2311.135. (source)

UPDATE: As of last week (8/13), Google has added support for Browser = Edge, but so far I am not seeing traffic equal to that of a custom segment built around the announced user agent of Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.<OS build number>

@laurenancona Hmm. How many days of data are you comparing between Google's method and yours?

[Lauren Ancona]

Interestingly, this appears to be resolving as of yesterday. 2nd in chart is the GA `Browser` = `Edge` I made a second custom segment based on the 'official' user agent (3rd in chart) just to see if it was different from the built-in.

[Eric Mill]

OK - given that, I'm inclined to rely on Browser = Edge, at least for our work. Do you think that's okay, or would you like to collect more data?

[Lauren Ancona]

I think if nothing else, it's consistent with the way we're mapping other Browser data. I'd like to confirm with a few more days' data, but otherwise I'd be okay with using.

[Eric Mill]

Cool. If you remember, please post the updated data here in a few days. Otherwise, we'll get to this eventually during our next round of work.

This is now fully supported via GA and was added to the dashboard in 3f5cd38
