Note: the SD-JWT feature has been marked as "at risk", because it is not clear when the dependency on the IETF work will reach the required status.

I don't see any wide review requests for those changes, including horizontal reviews. Some changes impact security/privacy and would be good to get a review of those. Note that linking to previous horizontal requests is nice but we're looking for hoirzontal reviews for the changes since 25 April 2024.
