Stable release date: August 25th, 2026
Unless otherwise noted, the following changes apply to Chrome 152 stable channel release for Android, ChromeOS, Linux, macOS, and Windows.
##### CSS and UI
###### CSSPseudoElement support for ::backdrop, ::scroll-marker, and ::view-transition
Support for CSSPseudoElement, previously defined for ::after, ::before, and ::marker, extends to include several new pseudo-elements:
- ::backdrop: Helps close a dialog when the backdrop is clicked without interfering with clicks inside the dialog content, eliminating the need for complex intersection logic to determine where the click occurred.
- ::scroll-marker: Used to collect click statistics.
- ::view-transition: Paves the way to supporting geometry-aware view transitions and intercepting a view transition mid-flight to start a new transition.

###### Relative alpha colors (CSS Color 5 alpha() function)
Relative alpha colors reference an origin color and modify only the alpha channel, letting developers set transparency relative to an existing color value.

###### window-drag CSS property
The window-drag CSS property lets web content designate regions of an installed desktop web app UI that behave as draggable window title bar areas. When applied, pointer interactions such as click-and-drag move the top-level application window rather than triggering normal page interaction. This feature standardizes and renames the existing app-region CSS property, changes its value names to move and none, and adds explicit inheritance behavior.

##### DOM and HTML
###### Expose the autocorrect global HTML attribute
The HTML autocorrect attribute lets web authors control whether autocorrection applies to user input in editable elements including <input>, <textarea>, and contenteditable hosts. This feature exposes the autocorrect global HTML attribute and reflects it on HTMLElement.

###### OpaqueRange
OpaqueRange represents a live span of text within a form control value, such as a <textarea> or text-based <input>, so developers can work with value text using range-like APIs. It enables operations such as getBoundingClientRect(), getClientRects(), and integration with the CSS Custom Highlight API for inline suggestions, highlights, and anchored popovers. It preserves encapsulation by exposing only value offsets while returning null for startContainer and endContainer.

###### Reference Target for cross-root ARIA
Reference Target enables ID attributes like <label for>, aria-labelledby, popovertarget, and commandfor to be forwarded to elements inside a component's shadow DOM, while maintaining encapsulation of internal state. When a shadow host specifies an element in its shadow tree to act as its reference target, all ID references pointing to the shadow host are forwarded to the reference target element instead. The reference target can be set declaratively using the shadowrootreferencetarget attribute on <template> or in JavaScript using ShadowRoot.prototype.referenceTarget.

##### Web apps
###### Notification attribution for PWAs on macOS
When a Progressive Web App (PWA) is installed on macOS, its notifications are natively attributed to the PWA itself (using its own name and icon in Notification Center) rather than Google Chrome. PWA notifications align with native macOS applications: Chrome no longer supports the requireInteraction field for notifications on macOS, and the Badging API requires notification permissions for the app badge to appear.

###### Sub apps for Isolated Web Apps
Sub apps allow developers to create multiple apps under a single Isolated Web App (IWA) installation. Each sub app has its
