Caniuse: Safari TP 58 supports SameSite cookie attribute

See https://developer.apple.com/safari/whats-new/ and https://webkit.org/blog/8327/safari-technology-preview-58-with-safari-12-features-is-now-available/

Neither of those links seem to mention SameSite cookie attribute. Am I missing something?

[srudolph-credera]

I wouldn't have caught it either if they hadn't mentioned it in one of their WWDC presentations: https://developer.apple.com/videos/play/wwdc2018/207/.

From the first link, under Security and Privacy / Intelligent Tracking Prevention 2.0:

Added support for specifying cookies that shouldn’t be sent for cross-site requests.

And the second link gives a catch-all and points to the first link, appearing to indicate that support for this feature has landed with TP 58:

Many more WebKit features in Safari 12 are present in this release of Safari Technology Preview and have been in past releases.

Thanks for finding the ground truth on this @danielcompton - now I'll know where to look in the future!
