Future JavaScript Website Compatibility Issues

Earlier this year some of the more popular browsers removed a JavaScript function (showModalDialog) that broke a number of websites, including the widely used Outlook Web App. There wasn’t much warning. Some of the Chrome release notes pre version 37 listed the function as deprecated. But, when version 37 came out and removed the function the release notes didn’t even mention the removal.

This breaking change sparked my interest in what future changes might break the websites I work on. I thought this would be pretty accessible information, but after actually putting in the research I found that not to be true. What I found was Compatibility Websites that were outdated or Browser specific technical information that wasn’t easily organized. The Safari/WebKit information is by far the hardest to look through. So I decided to pull together the best information/links for each of the 4 most popular browsers for myself to reference and anyone else that might be running into the same issue. What we really need is an updated site with all of this browser information together!

If I missed any good resources comment and let me know!
