This is a development machine. I write software that runs in browsers, including yours. I would keep your browser current in terms of releases, except that the framework I use does not always keep up. I do try to keep up with your security releases. That is certainly worth the risk and effort. Your information says that the 'releases' update channel 'includes' security releases. How about an update channel that ONLY contains security releases?

And, by the way, how do I find out the number and properties of an impending update? I am only presented with a button to install a release. No information of what I am installing.
