Hello.
I’m using MDN mainly to check what features are available for Internet Explorer since I’m working on an old MFC project using the WebBrowser control and depending on ActiveX.
Unfortunately it seems that Internet Explorer is not listed any more in compatility data. Is this an issue or is this an official decision, and is it possible to find some kind of snapshot of the MDN site with those data available?
Hi @Jean-Xavier_Bardant and welcome to the community 
I also saw this when looking something up yesterday. It looks like this was an official decision. Here’s the PR with the change and the reason: https://github.com/mdn/yari/pull/6602.
The underlying browser compatibility data is still available. It’s for example used on https://caniuse.com/ which cooperates with MDN. That’s a site I frequently use to check compat data.
I hope that helps. 
Have a nice day,
Michael
Thank you a lot, it does help. I don’t really understand this decision (people get info about old technologies mainly to maintain old stuff, not to code new one), but this is another matter.
