Apple veröffentlicht macOS-Update für Safari 13

General

New Features

• Added Desktop-class Browsing to Safari for iPad. Safari for iPad displays the same desktop websites as Safari for macOS, and provides the same capabilities. In addition it has more keyboard shortcuts, a download manager with background downloads, and support for top productivity websites.
• Added opt-in dark mode support for websites in Safari for iOS.
• Added support for aborting Fetch requests.

Authentication and Passwords

New Features

• Updated Safari to prompt the user to change weak passwords when signing into a website. Requesting a password change uses the well-known URL for changing passwords, enabling websites to specify the page to open for updating a password.
• Added support for FIDO2-compliant USB security keys with the Web Authentication standard in Safari on macOS.
• Added support for Sign in With Apple to Safari and to WKWebView.

Security and Privacy

New Features

• Added a permission API on iOS for DeviceMotionEvent and DeviceOrientationEvent.
• Changed the behavior for third party iframes to prevent them automatically navigating the page.
• Updated Intelligent Tracking Prevention to prevent cross-site tracking through referrer and through link decoration.
• Improved the privacy of local WebRTC data connections with mDNS ICE candidates.
• Increased the security for WebKit sandboxes on iOS and macOS.

Layout and Rendering

New Features

• Added support for one-finger accelerated scrolling to all frames and overflow:scroll elements eliminating the need to set-webkit-overflow-scrolling: touch.
• Changed the default behavior on iPad for wide web pages with responsive meta-tags that require horizontal scrolling. Pages are scaled to prevent horizontal scrolling and any text is resized to preserve legibility.
• Added support for CSS conic gradients.

Performance

New Features

• Reduced the initial rendering time for webpages on iOS.
• Added automatic support for Fast Tap to desktop websites on iPad.

• Updated editing callouts to avoid in-page controls.
• Added intelligent whitespace to editable WebViews and editable areas of webpages.

Payment Request API

New Features

• Added support for Apple Pay on the Web to WKWebView. Note that using script injection APIs, such as WKUserScript or evaluateJavaScript(_:completionHandler:) disables Apple Pay for that view.

Media

New Features

• Added support for the decodingInfo() method of the Media Capabilities API for checking supported codecs, efficiently supported codecs, and optional codec features including alpha.
