Fabrice Canel from Microsoft Bing introduced on the Bing weblog that the search firm will retire the legacy BingBot user-agent within the Fall of 2022. As an alternative, Bing will use a user-agent that’s extra consultant of its evergreen BingBot rendering engine. Bing introduced the brand new consumer brokers again in 2019 however I suppose this now means the previous one goes away for good.

So out with this user-agent by the Fall of 2022:

Mozilla/5.0 (appropriate; bingbot/2.0; +http://www.bing.com/bingbot.htm)

In with these two new user-agents by the Fall of 2022:

Desktop:

Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; appropriate; bingbot/2.0; +http://www.bing.com/bingbot.htm) Chrome/W.X.Y.Z Safari/537.36

Cellular:

Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Construct/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/W.X.Y.Z Cellular Safari/537.36 (appropriate; bingbot/2.0; +http://www.bing.com/bingbot.htm)

The “W.X.Y.Z” within the strings above, could be substituted with the most recent Microsoft Edge model Bing is utilizing for crawling, similar to “100.0.4896.127″.

When you arduous code something for user-agents, you must replace these particulars.

As an FYI, Google did the identical factor with Googlebot consumer brokers a pair years in the past.
