HTML Living Standard just removed application cache related code/documentation. Does this mean it got deprecated completely?

Title says most of it. Until today it was possible to see application cache related documentation in https://html.spec.whatwg.org/#applicationcache

Now, the page doesn't show anything related to application cache. Does this mean it got completely deprecated?

Is there a way to find the old documentation? Will old browsers like Edge not be able to support Application Cache any more even though they supported it until yesterday?

• Yes it's deprecated. It's already been removed from Chrome and Firefox since a few versions in non secure contexts and will be soon in any context in all major browsers.
• You already found an old version of the specs but this is not the "documentation", it is the rules for implementers, and don't require keeping deprecated features in there. User-docs are still available on MDN
• No old browser won't stop doing what they've been written to do magically because someone changed the text of whatwg website.
