I use Chrome stable and Chrome Canary on my laptop. I use Stable channel for work, and Canary for other stuff (read life). Canary channel was created because you cannot run Stable version and Dev or Beta versions side-by-side. Looks like that is changing.
Starting today, we will be able to run Chrome Stable / Beta / Dev side-by-side. I do not know if Canary channel will continue to exist, but if they can update Dev as frequently as Canary, I am fine with that too! There is no mention of Canary in the announcement blog post, so I think it is going to be like this for now.
There is another platform where it is already possible to run different channels at the same time. Android. On Android, you can install Stable, Beta, Dev and Canary channels as separate apps.
Starting today, Chrome Beta and Chrome Dev can be installed on the same Windows computer as stable Chrome and run simultaneously, allowing developers to more easily test their site across multiple versions of Chrome. This means side-by-side Chrome installation is available on Windows, Android, and Linux, and will be made available on other platforms in future releases.
How To Install Different Chrome Channels Side-by-side
To install Chrome Beta or Chrome Dev, visit the Chromium release channels page. If you already have Chrome Dev or Beta and wish to run it side-by-side with stable Chrome, you’ll need to uninstall it and then reinstall from this page.
How many of you use something other than Stable, to get new features early? Drop me a comment and say hi!
