On August 25, Google announced that Google News shall no longer use a separate bot to crawl. It shall use the Googlebot henceforth.
“Google News recently updated our infrastructure to crawl with Google’s primary user-agent, Googlebot. What does this mean? Very little to most publishers. Any news organizations that wish to opt out of Google News can continue to do so: Google News will still respect the robots.txt entry for Googlebot-News, our former user-agent, if it is more restrictive than the robots.txt entry for Googlebot.” - Google News Product Specialist David Smydra
However, for analytics, traffic shall still be able to be differentiated between Google Search and Google News.
