Safari now supports CHIPS – opt-in partitioned cookies!
Cross-site resources that aren't from known tracker domains can set cookies with response headers like this:
Set-Cookie: TestCookie=12345; SameSite=None; Secure; Partitioned

@wilander@mastodon.social This is great! And it comes just in time as I happen to need it for a project I'm currently working on. I do wonder though, why is this needed in the first place? Why not just partition cookies by default like we do with all other storage APIs? I can't think of any scenario where it would break existing sites.

@wilander@mastodon.social nice one. I love that Connection Security Details are also available now on iOS/iPadOS.

@wilander@mastodon.social how does this differ from ITP? I thought Safari was already partitioning third party cookies by default.
