What’s new with WebKit in Safari 15

WebKit, an open-source engine developed by Apple, powers the rendering of HTML and CSS in browsers like Safari and Chrome and is utilized by various devices, including PlayStation consoles, Blackberry Browser, and Amazon Kindle. Originating from a fork of KDE's KHTML and KJS libraries, WebKit has seen contributions from companies like Apple, Google, Nokia, and Blackberry, supporting diverse operating systems such as macOS, Windows, and Linux. Safari 15 has introduced significant updates to WebKit, enhancing privacy through features like computerized HTTPS improvements and PassKeys, and providing customization options with extension APIs for browser personalization. The latest updates also include improvements to Apple Pay, enabling developers to use the Payment Request API for flexible payment options, and have enhanced media capabilities and the user interface, such as aspect-ratio CSS property to improve element responsiveness and new tab-bar designs for better usability on iOS. These advancements are accessible on various Apple devices, reflecting a commitment to privacy, security, and user experience enhancements.
