Chrome 147 Beta: New Features and Security Enhancements Unveiled
Google published the Chrome 147 beta (March 11, 2026) announcing a broad set of web-platform, privacy, and developer-facing changes across Android, ChromeOS, Linux, macOS, and Windows. Highlights include new scroll named ranges for ViewTimelines, new CSS features (contrast-color(), border-shape), Element-scoped view transitions, a CSSPseudoElement interface and pseudo-element event targets, WebXR Plane Detection and Layers, support for JSON/style modulepreload, Math.sumPrecise (TC39 proposal), and SVG <textPath> path attribute support. Chrome ships a Rust XML parser for non-XSLT scenarios and begins phasing out certain XSLT uses for SVG. Privacy and security updates add or expand Local Network Access (LNA) restrictions (WindowClient.navigate, WebSockets, WebTransport), update Device Memory API values to reduce fingerprinting, and introduce several origin trials (Container Timing, Autofill event, Connection allowlists).
A major browser release from Google introduces platform APIs, privacy changes (LNA, Device Memory API limits) and new web capabilities that affect tracking, fingerprinting, measurement, and web ad integrations; these platform-level changes materially impact web and adtech implementations.

Chrome 145 Beta: Major Upgrades for Web Developers!
Google published the Chrome 145 beta on January 14, 2026, delivering a broad set of web-platform, UI/CSS, privacy and measurement updates across Android, ChromeOS, Linux, macOS and Windows. Notable additions include the Origin API, Device Bound Session Credentials (DBSC), cookie-store maxAge, new performance timing fields (paintTime, presentationTime) and changes to the LayoutShift API to report in CSS pixels. Chrome 145 also splits Local Network Access permissions, exposes additional animation events, refines rendering of high border-radius elements, adds column-wrap support for multi-column layouts, and requires sticky activation for clipboardchange. As part of privacy work, Chrome will remove the UserAgentReduction policy so reduced User-Agent strings are sent by default and sites are encouraged to use User-Agent Client Hints (UA-CH). The release includes deprecations such as removal of obsolete macOS virtual camera support.
Chrome 149 Beta Released
Google published the Chrome 149 beta on May 6, 2026, describing new browser platform features across CSS, Web APIs, and origin trials for Android, ChromeOS, Linux, macOS, and Windows. Notable changes include new and extended CSS capabilities (support for path(), shape(), rect(), xywh(), image-rendering: crisp-edges, and a new path-length CSS property), scoping system accent color exposure to installed web apps to reduce fingerprinting, and behavioral tweaks like clipping text overflow during user interaction. Web API updates include programmatic scroll promises, Request.isReloadNavigation, WebSocket handling for bfcache, and Payment Request improvements for distinguishing internal errors. Chrome 149 also opens origin trials for features such as a focus-without-user-activation permissions policy, an event-driven Gamepad API, and WebAssembly custom descriptors.
