Promoting r495 to LTS.
Newer releases have a setting to disable update notifications, but unfortunately it came after r449 so it doesn't respect that. We will publish a patch for r449 in the near future that respects the setting in newer releases so it won't show update notifications. We'll look into what can be done about installed apps, but it might be limited by what Chrome supports (I don't believe there's a way to choose between the launch URL, and the default is the latest on the release channel.)
Appreciate it! And if there is a way to easily swap versions from the chrome app, that would be brilliant.
