The second important part of this story is that Microsoft will also be bringing this new version of Edge to more platforms.
In response to Microsoft's announcement, Google said it welcomes the Windows maker to the open source community.
Microsoft invites developers to join Microsoft Edge Insider to test preview builds of the new Edge when they become available.
The change isn't expected to roll out until next year sometime, but it should be good news from Edge.
The move to Chromium will allow Microsoft to deliver frequent updates to Edge on Windows 10, even on older versions of the OS, which is something that hasn't been possible in the past.
That new browser is said to now carry the codename Anaheim, and will replace Edge as the default browser for Windows 10. Once Edge is updated, hopefully they will only notice that sites and apps they visit using Edge will work better and faster.
Microsoft's decision to shift Edge to Chromium is less surprising in light of Edge for Android and iOS, which run on the Blink rendering engine from Chromium and WebKit (the basis of Apple's Safari browser) respectively.
Microsoft on Thursday said it intends to use the open-source Chromium browser engine in the desktop version of its Edge browser, promising the two per cent of global internet users who favor Edge an improved web experience.
Microsoft officials haven't said when they expect the new Edge to roll out to the mainstream, but it won't be anytime very soon, based on this schedule.
In a blog post announcing the move, Joe Belfiore, Corporate Vice President of Windows, stated that "we intend to adopt the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility for our customers and less fragmentation of the web for all web developers". However, we believe that everything that makes Edge unique, such as its focus on inking, providing an excellent reading and PDF experience, will still be there in the new Edge. I hear the answer is no. Edge is going to be rebuilt in Chromium, a change that will happen under the hood and will mostly go unnoticed by users. What this means is that Microsoft has to invest heavily in upgrading its engine while also dealing with whatever issues Chrome introduces as many devs only build websites that render using that engine and fail to check to see if other browsers render correctly.
Why is Microsoft continuing to try to gain adoption for its own browser, in spite of Edge's continued tiny market share?
