The Android build can now run the Language Detector API, which reads text handed to it from JavaScript and returns the language it is written in. Detection runs on a machine learning model installed on the device, so text is processed without being sent to a server, and detection still works offline when the needed model is already present. The CSS side gets the new corner property, which folds border-radius and corner-shape into one declaration, plus corner-top and corner-bottom variants and writing-direction forms such as corner-block-start. The text-overflow property now accepts an arbitrary string in place of the standard ellipsis, and text-decoration-inset adjusts how far underlines, overlines and strikethroughs run. The stable release also carries 213 security fixes, and Chrome 158 is set for November 17, 2026.","whyItMatters":"Chrome 157 puts a language classifier on Android devices that previously had to send text to a server, and the same release carries 213 security fixes, so the browser's feature and security maintenance land together.","webCardHtml":"\u003cp\u003eAlongside the language and CSS work, Chrome 157 carries a long list of smaller platform changes. The position-visibility CSS property now accepts anchor-valid and anchor-visible, with the older plural forms kept as deprecated aliases. The Sanitizer API gains a javascriptURLs option so developers can control how JavaScript URLs are sanitized, and Service Worker now supports ProgressEvent.

The 213 fixes include Critical-rated issues such as a buffer overflow in Dawn (CVE-2026-121156) and memory corruption in ANGLE (CVE-2026-121229), plus High-rated flaws including incorrect authentication in BackgroundFetch (CVE-2026-121107) and an out-of-bounds read in ANGLE (CVE-2026-121197). Desktop builds are 157.0.8103.38/.39 for Windows and macOS, and 157.0.8103.38 for Linux. Android is 157.0.8103.38, due on Google Play within a few days, while desktop rolls out gradually over the coming days to weeks or can be pulled manually from Chrome\u0026#39;s settings.\u003c/p\u003e","blueskyPost":"Chrome 157 runs Android language detection on a model already on the phone, so it works offline. The tradeoff is model size and staleness: a language the installed model does not cover returns nothing until Google ships an update.","twitterPost":"Chrome 157 detects language on-device, so no server call is needed. What it cannot detect is whatever language the installed model was never trained on.","threadsPost":"Chrome 157 moves Language Detector API calls to a model installed on the Android device, which is why detection survives offline. That design also sets the limit: accuracy now depends on which model version is on the phone, and Google has to push new models to fix weak languages.","newsletterBlurb":"Chrome 157 lands with on-device language detection for Android and no fewer than 213 security fixes. The CSS side gets a single corner property and arbitrary strings for truncated text.
