This update applies to Chrome versions on Windows, Android and Linux. Google said other operating systems will receive support in the future.
Note that this change does not take the update form. To run two versions of Chrome simultaneously, users need to uninstall existing versions of Beta and Dev, reload them from the official website and reinstall the version they want to use.
Before installing either Chrome Beta or Dev, make sure you save or synchronize bookmarks, passwords or anything else saved on the unstable version.
Previously, users who wanted to use another Chrome environment had to run the Portable versions of Google Chrome Stable and then choose either Beta or Dev.
