Microsoft Edge preview builds: The next step in our OSS journey | Windows Experience Blog

In December, we announced our intention to adopt the Chromium open source project in the development of Microsoft Edge on the desktop. Our goal is to work with the larger Chromium open source community to create better web compatibility for our customers and less fragmentation of the web for all web developers.
Today we’re embarking on the next step in this journey – our first Canary and Developer builds are ready for download on Windows 10 PCs. Canary builds are preview builds that will be updated daily, while Developer builds are preview builds that will be updated weekly. Beta builds will come online in the future. Support for Mac and all supported versions of Windows will also come over time.
In these first builds we are very much focused on the fundamentals and have not yet included a wide range of feature and language support that will come later. You’ll start to see differences from the current Microsoft Edge including subtle design finishes, support for a broader selection of extensions and the ability to manage your sign-in profile. We look forward to people starting to kick the tires and will be refining the feature set over time based on the feedback we receive.
Along with what’s visible in the browser itself, we’ve also begun to make contributions back to the Chromium open source project. These include areas like accessibility, touch, ARM64 and others. We’re working directly with the teams at Google and the broader Chromium community on this work  and appreciate the collaborative and open discussions. We look forward to continued engagement with the community to progress Chromium in these areas and others.
We hope those of you who are comfortable testing early software or are part of the open source community developing browsers will use these builds at least a little bit every day. Ultimately, we’re looking for your feedback – what’s working well, what’s not working and what things you’d like to see in the final product. The more you use early builds and give us feedback, the better we can make the final product. In fact, your use at this early stage helps us find bugs that we can fix for not just the next version of Microsoft Edge, but other browsers built using Chromium as well.
If you’re ready to participate, we invite you to visit the Microsoft Edge Insider site and download now. You can also read more about the new preview builds and our participation in the Chromium community on the Microsoft Edge Developer Blog.
As a reminder – people using current Microsoft Edge who don’t feel comfortable trying out early software, there’s nothing you need to do now. The Microsoft Edge you use today isn’t changing. However, if you’d still like to follow along with the latest, check out the Microsoft Edge Insider site.
Thank you to everyone who is engaging with us on this work. We look forward to sharing more details and updates as we continue on the journey.
Thanks,JoeB

Microsoft Edge: Making the web better through more open source collaboration – Windows Experience Blog

For the past few years, Microsoft has meaningfully increased participation in the open source software (OSS) community, becoming one of the world’s largest supporters of OSS projects. Today we’re announcing 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.
As part of this, we intend to become a significant contributor to the Chromium project, in a way that can make not just Microsoft Edge — but other browsers as well — better on both PCs and other devices.
Making the web better for many audiences
Working with open source is not new for Microsoft Edge. Our mobile browser has been based on open source from its beginnings over a year ago. We’ve also used open source for various features of Microsoft Edge on the desktop (e.g. Angle, Web Audio, Brotli) and we’ve begun making contributions to the Chromium project to help move browsing forward on new ARM-based Windows devices.
Our goal is to do this in a way that embraces the well-established open source model that’s been working effectively for years: meaningful and positive contributions that align to long-standing, thoughtfully designed architecture, and collaborative engineering. Together we seek the best outcome for all people who use the web across many devices.
Ultimately, we want to make the web experience better for many different audiences. People using Microsoft Edge (and potentially other browsers) will experience improved compatibility with all web sites, while getting the best-possible battery life and hardware integration on all kinds of Windows devices. Web developers will have a less-fragmented web platform to test their sites against, ensuring that there are fewer problems and increased satisfaction for users of their sites; and because we’ll continue to provide the Microsoft Edge service-driven understanding of legacy IE-only sites, Corporate IT will have improved compatibility for both old and new web apps in the browser that comes with Windows.
Microsoft Edge + OSS: a new emphasis for Microsoft
Over the next year or so, we’ll be making a technology change that happens “under the hood” for Microsoft Edge, gradually over time, and developed in the open so those of you who are interested can follow along. The key aspects of this evolution in direction are:
1. We will move to a Chromium-compatible web platform for Microsoft Edge on the desktop. Our intent is to align the Microsoft Edge web platform simultaneously (a) with web standards and (b) with other Chromium-based browsers. This will deliver improved compatibility for everyone and create a simpler test-matrix for web developers.
2. Microsoft Edge will now be delivered and updated for all supported versions of Windows and on a more frequent cadence. We also expect this work to enable us to bring Microsoft Edge to other platforms like macOS. Improving the web-platform experience for both end users and developers requires that the web platform and the browser be consistently available to as many devices as possible. To accomplish this, we will evolve the browser code more broadly, so that our distribution model offers an updated Microsoft Edge experience + platform across all supported versions of Windows, while still maintaining the benefits of the browser’s close integration with Windows.
3. We will contribute web platform enhancements to make Chromium-based browsers better on Windows devices. Our philosophy of greater participation in Chromium open source will embrace contribution of beneficial new tech, consistent with some of the work we described above. We recognize that making the web better on Windows is good for our customers, partners and our business – and we intend to actively contribute to that end.
What happens next
If you’re a Microsoft Edge customer, there is nothing you need to do as the Microsoft Edge you use today isn’t changing. If you are a web developer, we invite you to join our community by installing preview builds when they’re available and staying current on our testing and contributions. We expect to have a preview build ready in early 2019 for you to try for yourself.
If you’re part of the open-source community developing browsers, we invite you to collaborate with us as we build the future of Microsoft Edge and contribute to the Chromium project. A few near-term examples will include continued work on ARM64 support, web accessibility, and taking advantage of other hardware features like touch support.
We look forward to sharing more details in the future as we test and learn. We are excited about the opportunity to be an even-more-active part of this community and bring the best of Microsoft forward to continue to make the web better for everyone.
Thanks,
Joe
