Apple launches Safari 190 preview: fixes and improvements to many features

Apple today launched an update to Safari Technical Preview 190. This update mainly fixes and improves features such as history, CSS, HTML, JavaScript, media, network, SVG, URL, Web API, and Web Inspector.

#Users can install the latest version through the "Software Update" option in the browser's "System Preferences" or "System Settings".

The content of this update is as follows:

New support for CTAP function

The flexbox attribute in CSS adds support for the safe keyword.

Add support for CSS style container queries.

Fixed History property to throw SecurityError when not in a fully active document

Added shadowrootclonable property support, consistent with standards changes for declarative shadow roots. In particular, web developers must now set this property if they want their declarative shadow roots to be cloneable.

Using eval () directly in a default value expression within the remaining parameters creates a variable in the function environment rather than in the independent environment of the parameter.

Fixed pseudo element font size calculation to fix subtitle size in full screen mode.

Removed non-standard VTTRegion.track.

Fixed for escalating inactive or passive sub-resource requests and acquisitions in possible mixed security scenarios.

Fixed issue with loading WebArchives using non-persistent data stores.

SVG Support has been added for turn cells in .

Web API Web Application Programming Interface Fixed an issue where changing HTMLCanvasElement width or height would cause intermediate buffer allocation.
