Bing announced yesterday that BingBot is going evergreen, just like GoogleBot did. Bing said this will happen over the next few months and the user agent for BingBot might change but most sites don't need to do anything or worry about anything with this change.
This change is pretty much the same change Google made with its bot months ago. It means Bing, like Google, can now crawl, render and index more of your content as the end user sees it. Bing wrote:
By adopting Microsoft Edge, Bingbot will now render all web pages using the same underlying web platform technology already used today by Googlebot, Google Chrome, and other Chromium-based browsers. This will make it easy for developers to ensure their web sites and their Content Management System work across all these solutions without having to spend time investigating each solution in depth.
With Bing and Google pretty much being in sync here, this should make the SEO day-to-day a bit easier going forward.
Here is the tweet with the announcement at PubCon yesterday:
