Chrome 150 adds new CSS properties, patches 382 flaws, and continues Manifest V2 removal

Google has released Chrome 150, introducing key features and addressing major security concerns. This version patches 382 security flaws, including 15 critical vulnerabilities. While there are currently no reports of active exploitation, updating promptly is advised for all users.

For developers, Chrome 150 brings the new text-fit CSS property. This property automatically scales text node font sizes to fill the width of their containers, eliminating the need for manual calculations or custom scripts. Alongside this, the border-area value is now supported in background-clip, allowing backgrounds to be clipped to the area painted by border strokes. Both features aim to improve responsive design and styling precision.

Building on developer improvements, the focusgroup attribute introduces native arrow key navigation, a guaranteed tab stop, and last-focused memory to composite widgets. This enhancement streamlines keyboard accessibility features while reducing the need for hand-rolled JavaScript solutions.

On the extension platform front, Chrome 150 continues Google’s removal of Manifest V2 support. Workarounds like command-line switches for running older extensions have been disabled, accelerating the transition to Manifest V3 and impacting users and developers relying on historical extension technology.
