We've completed our work on Web Security documentation on @npub1azl…tw5z !
The entire MDN content tree has been reworked and now features in-depth information on:

We've updated MDN's guide on Subresource Integrity (SRI) and added docs for the HTML `integrity` attribute.
The SRI docs now talk about the fact that you can provide multiple `integrity` values (using the same or different hash functions) and how browsers will handle that.
Thanks to @npub19qj…0ztu for your feedback! We're looking forward to improved SRI support in @npub1l0c…kt92!

We've written a new guide on Fetch Metadata!
Fetch metadata is a group of HTTP request headers.
They tell you if requests are navigation between documents, request for a subresource, or requests made from JavaScript, and whether they are same-origin, or same-site, or from completely different sites.
Thanks to this information, you can implement defenses against cross-origin attacks such as cross-site request forgeries (CSRF) and various cross-site leaks.

In 2024, thanks to an investment from @npub1yng…nhrk, we systematically collected compatibility data for 30 browser releases throughout the entire year. As a result, whenever browsers shipped new features, the data was already available on @npub1azl…tw5z, caniuse.com, and other projects.
