Safari 13.1 adds support for the async Clipboard API.

With the release of iOS 13.4, iPadOS 13.4, and Safari 13.1 in macOS Catalina 10.15.4, web developers have a new API at their disposal: Web Animations.

For years now, web developers have desired the ability to design components that are responsive to their container instead of the viewport.

Since announcing last April that WebKit supports the W3C Payment Request API for Apple Pay, we’ve been hard at work adding even more features to the API.

Safari 11 was the first Safari version to support WebRTC.

Web authors often need to know when a particular element on a page becomes visible.

Transport Layer Security (TLS) is a critical security protocol used to protect web traffic.

Over the last 8 months we have been working on adding support for Web Animations, a W3C standard offering Web developers a JavaScript API to create, query and controls animations.

We’re pleased to announce that Safari 11.1 on macOS and Safari on iOS 11.3 now support the W3C Payment Request API for conducting Apple Pay transactions on the web.

The Clipboard API provides a mechanism for websites to support accessing the system pasteboard (pasteboard is the macOS and iOS counterpart to clipboard on Windows and Linux).

HTTP Strict Transport Security (HSTS) is a security standard that provides a mechanism for web sites to declare themselves accessible only via secure connections, and to tell web browsers where to go to get that secure version.
