The Chromium-based Microsoft Edge browser is facing the millennium bug test. This is because all web browser version numbers currently use a two-digit scheme. Therefore, at the critical node that is about to enter 100, manufacturers including Google and Mozilla are actively testing to solve this problem.
In September of last year, Google began preparing for the inevitable, and now Microsoft is conducting its own tests. Interestingly, Microsoft has adopted a very similar strategy to Google. The company has added two experimental flags.
Both of these flags basically force the User-Agent identifier to report that Microsoft Edge is on v100. How the website responds or reacts to this information is critical. Needless to say, websites will have to understand and accept a three-digit version and respond by properly interfacing with the browser.
Every web browser has a user agent ID, which is associated with the same version. It helps website developers adapt to the special or unique features, quirks, behavior patterns, etc. of web browsers. Developers can even add special, browser-specific features based on user-agent information.
At present, the stable version of Microsoft Edge is still v97, and the Dev channel version is v99. Since Microsoft has adopted a 4-week update schedule for its browser, users can expect v100 to be released in the first half of 2022.
