Has Google changed useragent?

Hi!

I'm pretty new here so i hope i post in the right forum.

Anyway, I started with some new adwords campaigns yesterday and noticed that the useragent is no longer Adbot. I didnt have any visits from Adbot at all but all visits where from Googlebot.

Is this some new stuff google is doing?

I have run serveral Adwords campaigns before but Google has always had useragent set as Adbot before.

Anyone seen the same thing?

EDIT: I also should add that there are no backlinks to this campaign and that the hosting came up the same day.

Alright, next campaign set up. This time i got visits from Adbot.

This is really weird... I wonder what is going on at Amphitheatre Parkway sometimes

Another time i got a normal Useragent string from adbot, like "Mozilla Compatible xxxx" but in the end it said (referer translate.google.com)... Is'nt that really weird?
