Google released the stable version of Chrome 152 for Windows, macOS, and Linux on August 25, 2026. The update introduces the CPU Performance API, which lets websites determine the CPU performance tier of a user's device and adjust experiences accordingly. It can be combined with the Compute Pressure API to respond to changes in CPU load. Chrome 152 also exposes the HTML autocorrect attribute, allowing web authors to control automatic corrections in editable elements such as input fields and textareas. New CSS features include media element pseudo-classes for playback states like playing, paused, seeking, and muted, plus the window-drag property for desktop web apps. The update adds a connection allowlist to restrict external server connections via the Fetch API. For WebGPU, the optional subgroup-size-control feature was added to optimize compute shaders, particularly for AI workloads. Chrome 152 includes 327 security fixes, with 10 rated Critical. Google also announced plans to remove the Private Aggregation API and other Privacy Sandbox APIs. The next version, Chrome 153, is scheduled for September 8, 2026, under a new two-week release cycle.
Google moved Chrome 152 to the stable channel on August 25, 2026, for Windows, macOS, and Linux. The rollout is gradual, spanning days to weeks, and users can manually update from Chrome settings. The CPU Performance API, proposed on the WICG GitHub repository, exposes device CPU tier information to web applications. Developers can pair it with the Compute Pressure API to adapt to real-time load changes, aiming to improve user experience on lower-end hardware.
The update expands CSS pseudo-element support to include ::backdrop, ::scroll-marker, and ::view-transition. The ::backdrop pseudo-element simplifies dialog closing by allowing background clicks without blocking content clicks. Media element pseudo-classes, a focus area of Interop 2026, let styles change based on video or audio playback state, including :playing, :paused, :seeking, :buffering, :stalled, :muted, and :volume-locked. The window-drag CSS property lets developers set custom draggable regions in desktop web apps, moving the application window instead of triggering page actions.
On the security front, the update fixes 327 vulnerabilities: 10 Critical, 61 High, 184 Medium, and 72 Low. Notable Critical fixes include use-after-free issues in ANGLE, Aura, and Chromecast. Google also outlined the deprecation of the Private Aggregation API, which was exposed only through Shared Storage and Protected Audience APIs, both slated for removal.
