Download Google Chrome 92.0.4515.107

Google has released version 92 of its Chrome web browser. Google Chrome is available for Windows, Linux and macOS. There are also versions for Android and iOS, but they follow a slightly different release schedule. In version 92, the detection of phishing websites has been improved, among other things. Learn more about the changes made in version 92, in addition to the usual bug and security fixescan be found below.

File Handling API

Now that web apps are capable of reading and writing files, the next logical step is to let developers declare web apps as file handlers for files they create and process. The File Handling API allows you to do exactly this. For example, after a text editor PWA has registered itself as a file handler, you can right-click a .txt file in your operating system’s file manager and instruct this PWA to (always or just once) open .txt files. This means PWAs are just a (double) click away from the file manager.

This improves the user experience for PWA use cases, making them more like OS apps than they are already. For example:

• Office applications like text editors, spreadsheet apps, and slideshow creators.
• Graphics editors and drawing tools.
• Video game level editor tools.

File Handling is starting an origin trial in 92 that is expected to run until around the end of August, 2021. For more information on this feature, see Let web applications be file handlers. For information about other origin trials in this release, see Origin Trialsbelow.

Origin Trials

This version of Chrome introduces the origin trials described below. Origin trials allow you to try new features and give feedback on usability, practicality, and effectiveness to the web standards community. To register for any of the origin trials currently supported in Chrome, including the ones described below, visit the Chrome Origin Trials dashboard. To learn more about origin trials in Chrome, visit the Origin Trials Guide for Web Developers. Microsoft Edge runs its own origin trials separate from Chrome. To learn more, see the Microsoft Edge Origin Trials Developer Console.

New Origin Trials Shared Element Transitions

Shared Element Transitions allows a simple set of transitions in both single-page applications (SPAs) and multi-page applications (MPAs). This enhances the visual polish of pages with minimal effort by letting developers select from a set of user-agent provided transition effects. Without this, single-page app transitions are difficult since they require a careful coordination of animations and DOM manipulations to achieve the desired effect. Multi-page app transitions are, for the most part, not possible since each page can only control the contents of its own view. This origin trial is only for SPA use cases.

Change in Allowed App Shortcuts

Most Android launchers now allow only three app shortcuts instead of the previously allowed four. A shortcut to the site settings was added to the application icon in the Android launcher, taking one of the available shortcut slots for the app. For more information, see Get things done quickly with app shortcuts.

C.S.S size-adjust Descriptor for @font-face

Adds the size-adjust descriptor for @font-face allowing scaling of glyph sizes for a particular font face without affecting the CSS font-size and derived metrics such as em. CSS font-size can be seen as a scale factor for a box that the font draws in. Glyph sizes within that box vary between fonts, and size-adjust enables harmonizing them across different fonts. That’s why it reduces cumulative layout shift by matching up the fallback font and primary web font using this descriptor.

Imperative Slot Distribution Behavior

Imperative closing allows node-to-slot assignments without needing the slot attribute in markup. This enables dynamic slotting behavior based on input conditions and types. The feature originally shipped in Chrome 86; in this release some adjustments to the API have been made to ensure interoperability with other browsers.

javascript

This version of Chrome incorporates version 9.2 of the V8 JavaScript engine. It specifically includes the changes listed below. You can find a complete list of recent features in the V8 release notes.

Add dayPeriod option for Intl.DateTimeFormat

a dayPeriod option (part of ECMA402 2021) has been added to the Intl.DateTimeFormat() method so the caller can format times such as “7 in the morning”, “11 in the morning”, “12 noon”, “1 in the afternoon” , “6 in the evening”, “10 at night” (or in Chinese, “清晨7時”, “上午11時”, “中午12時”, “下午1時” ,”下午6時” ,”晚上10時”).

This enhances Intl.DateTimeFormat() to match what is already possible in C++ and Java by calling ICU and ICU4J. Without this feature, developers need to either format the quarter in the server or ship a set of day period patterns and hour to day period mappings from the server to client to perform such tasks.

Relative Indexing Method for Array, String, and TypedArrays

Adds a new method named at(), to Array.prototype, String.prototype, and the TypedArray prototypes, that permit relative indexing with negative indices. For example: let arr = [1,2,3,4]; arr.at(-1); // Returns 4

Intl BestFitMatcher by Using ICU LocaleMatcher

The ICU LocaleMatcher now implements the BestFitMatcher abstract operation to better match local data.

SharedArrayBuffers on Desktop Platforms Restricted to Cross-Origin Isolated Environments

SharedArrayBuffers on desktop platforms are now restricted to cross-origin isolated environments, matching the behavior recently shipped on Android and Firefox. A Cross-origin isolated page is considered a secure environment because it blocks loading cross-origin resources that are not opt-in and communicating with cross-origin windows. Only pages that opt-in to cross-origin isolation will be able to use SharedArrayBuffers. Learn more about the upcoming options at SharedArrayBuffer updates in Android Chrome 88 and Desktop Chrome 92.

Media Session API: Video conferencing actions

Adds actions to the Media Session API, specifically “togglemicrophone”, “togglecamera”, and “hangup”. This enables developers of video conferencing websites to handle these actions from the browser interface. For example, if the user puts their video call into a picture-in-picture window, the browser could display buttons for mute/unmute, turn-on/turn-off camera, and hanging up. When the user clicks these, the website handles them through the Media Session API. For more information, see the section from our recent articleor try our demo.

Tainted Origin Flag applied to Resource Timing

Chrome now accounts for the tainted origin flag when computing whether a fetched resource passes the timing allow origin check. The timing allow origin check is used in resource timing to determine whether the page can receive detailed timing information about a resource used in the page. The tainted origin flag impacts this check in cases where there are multiple redirects that cross origins. In those cases, the header should be ‘*’. In other words, it can no longer be a specific origin.

If a resource performs two cross-origin crosses (via redirects), then the developer needs to use Timing-Allow-Origin: * for the checks to pass. For example if a page on origin A fetches a resource on origin B, which redirects to a resource on origin C, then the tainted origin flag is set and the final resource needs to have Timing-Allow-Origin: * in order to receive detailed timing information.”

Web Bluetooth Manufacturer Data Filter

The Web Bluetooth API can now filter based on manufacturer data such as vendor ID and product ID. Developers have been able to prompt users through a browser picker to select a nearby Bluetooth device that matches their advertised name and services. However it hasn’t been possible to filter nearby Bluetooth devices based on advertised manufacturer specific data. Manufacturer data is specified through new properties on options.filters, which is passed to Bluetooth.requestDevice(). For more information, see Communicating with Bluetooth devices over JavaScript or try our demo.

Deprecations and Removals

This version of Chrome introduces the deprecations and removals listed below. Visit ChromeStatus.com for lists of current deprecations and previous removals.

Payment Handlers for Standardized Payment Method Identifiers

This feature, which enabled web-based payment handlers to receive paymentrequest events with non-URL, but standardized payment method identifiers, such as “basic-card” or “tokenized-card”, has been removed.
