Speeding up Google Chrome's release cycle
Later this year, we plan to shorten the release cycle and ship a new version of Google Chrome to the stable channel every four weeks, down from the current six-week cycle. There's more detail on the Chromium Blog about the impetus and rationale for this change.
One of my favorite aspects of being a web developer is the ease of deployment. I can fix a critical bug and deploy it to all of my users quickly. Moving to a four-week release cycle will give us more agility to get critical security and bug fixes out to users faster. And for developers, you won't have to wait as long for updates and bug fixes.
Shifting to a faster release cycle allows us to experiment and iterate on new features more effectively via origin trials, without having to wait as long between releases. It doesn't mean we'll be shipping more features, or shipping new features in less time. And it doesn't change the way we ship new features. We remain committed to working with standards bodies, our developer community, and the Chromium ecosystem.
Our current plan is for Chrome 94 to be the first release on the new four-week schedule, and it will be released on September 21st, 2021 (instead of October 12th, 2021). Each subsequent release will take place four weeks later. Thus, Chrome 93 (August 31st, 2021) will be the last release on the six-week schedule. We've updated our release calendar so you can see the updated dates.
As always, this may change based on feedback we receive from our team and the developer community.
What channel should I be using? #
As a web developer, it's a good idea to have both stable and beta installed on your device, and test your site in both. By using the beta channel, you can find and fix any issues before the majority of your users see them. With the beta channel you can start using new DevTools features sooner, and get early access to new web platform features. Side-by-side installation of the different channels of Chrome is available on all platforms, including Mac.
Today, it can take upwards of 2 weeks for the majority of users to move to the latest stable release. We believe that the four-week release cycle will allow us to more consistently move the majority of users to the latest stable release within 2 weeks. Of course, it's always a good idea to check the analytics for your site to understand how fast your users upgrade to the latest stable. In some scenarios, it may be longer.

Supporting developers #
We've tried to make sure that the impact of this change is minimal to web developers, but there are some things that we may have overlooked. We'll keep this post up-to-date as we progress. If you have questions, or concerns, reach out to @ChromiumDev on Twitter with the hashtag
We know this is a big change, but we feel strongly that it's something that will benefit everyone by reducing the time it takes to get important updates, and will improve the overall quality of Chrome.
