#### IDNA ContextJ rules

To improve interoperability with other browsers, Microsoft Edge now implements the IDNA ContextJ rules, by disallowing ZWNJ (U+200C ZERO WIDTH NON-JOINER) and ZWJ (U+200D ZERO WIDTH JOINER) characters in most places within URLs.

IDNA is the mechanism by which non-ASCII characters can occur in domain names. For example, the URL `http://네이버.한국/` is encoded as `http://xn--950bt9s8xi.xn--3e0b707e/`.

#### Browser Bound Keys in the Secure Payment Confirmation API

The Secure Payment Confirmation API can now keep up with syncing passkeys and device requirements for online payments. The Browser Bound Keys feature adds device binding in the browser, to enable payment scenarios in which device binding is required.

This feature helps meet requirements for device binding for payment transactions.
