Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 104 is beta as of June 23, 2022. You can download the latest on Google.com for desktop or on Google Play Store on Android.
Chrome on Desktop can now crop self-captured video tracks. Web apps are already able to capture video in a tab using getDisplayMedia(). Region capture allows web apps to crop a track and remove content from it, typically before sharing it remotely.
getDisplayMedia()
For example, consider a productivity web app with built-in video conferencing. During a video conference, a web app could use cropping to exclude the video conferencing portion of the screen (outlined in red below) avoiding a hall-of-mirrors effect. For more information, see Better tab sharing with Region Capture.
Media Queries enable responsive design, and the range features that enable testing the minimum and maximum size of the viewport are used by around 80% of sites that use media queries.
The Media Queries Level 4 specification includes a new syntax for these range queries. They can now be written using ordinary mathematical comparison operators. Also supported are the logical operators or and not, and nesting and evaluation of "unknown" features. For example, a media query previously written like this:
or
not
@media (min-width: 400px) { … }
Can now be written like this:
@media (width >= 400px) { … }
For more information, see New syntax for range media queries in Chrome 104.
This version of Chromium supports 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 Chromium, 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.
The focusgroup CSS property improves keyboard focus navigation using the keyboard arrow keys among a set of focusable elements. Adding this feature to browsers allows web developers to control focus navigation without custom solutions that can lead to a lack of consistency, accessibility, and interoperability. Sign up here for the Microsoft Edge origin trial. It's scheduled to last through 107.
focusgroup
Secure Payment Confirmation now supports a means for users to opt out of storing their credit card data to make later purchases easier. To use the new feature, set showOptOut to true on methodData.data, which is passed as the first parameter of the PaymentRequest() constructor. For example:
showOptOut
true
methodData.data
PaymentRequest()
const methodata = [{ … data: { … showOptOut: true … } }]; const request = new PaymentRequest(methodData, details);
To see an example in context check out the demo. You can sign up here for the origin trial. It's scheduled to last through Chrome 106.
Shared Element Transitions enables the creation of polished transitions in single-page applications (SPAs). Minimal development effort is required by devs to make transitions look nice; they can choose to use default animation properties, or they can customize their own transition effects to achieve the desired transition experience.Transitions are set declaratively using CSS properties. For more information, see Shared Element Transitions. Visit the dashboard to sign up for the origin trial.
The following features, previously in a Chrome origin trial, are now enabled by default.
Speculation rules provide a mechanism for web content to permit prefetching or prerendering of certain URLs. For example:
<script type="speculationrules"> { "prefetch": [ {"source": "list", "urls": ["/weather/kitchener", "/weather/seattle", "/weather/tokyo"]} ] } </script>
Subresource loading with web bundles is a way to load many resources efficiently. To use the feature a web page declares that certain resources are provided by a web bundle at a particular URL. For example:
<script type="webbundle"> { "source": "https://example.com/dir/subresources.wbn", "resources": ["https://example.com/dir/a.js", "https://example.com/dir/b.js", "https://example.com/dir/c.png"] } </script>
For information on creating web bundles, see Get started with Web Bundles. For more information on subresource loading using web bundles, see Origin Trial for Subresource Loading with Web Bundles.
When cookies are set with an explicit Expires/Max-Age attribute the value will now be capped to no more than 400 days. Previously, there was no limit and cookies could expire as much as multiple millennia in the future. This follows a change in the spec. 400 days was chosen as a round number close to 13 months. This duration ensures that sites visited roughly once a year (for example, sites for choosing health insurance benefits) will continue to work.
The object-view-box property allows authors to specify a portion of an image that should draw within the content box of a target replaced element. This enables creation of images with a custom glow or shadow applied, with proper ink-overflow behavior such as a CSS shadow would have. For more information, see First Look At The CSS object-view-box Property.
object-view-box
ink-overflow
Fullscreen Capability Delegation allows a Window to transfer the ability to call requestFullscreen() to another Window it trusts after relinquishing the transient user activation at the sender Window. This feature is based on the general delegation mechanism that shipped in Chrome 100.
requestFullscreen()
Fullscreen Companion Window allows sites to place fullscreen content and a popup window on separate screens from a single user activation. There is a demo available with source code on GitHub.
Web Bluetooth is now controllable with a Permissions Policy. The token is named "bluetooth" and has a default allowlist of 'self'.
"bluetooth"
'self'
The overflow-clip-margin property specifies how far an element's content is allowed to paint before being clipped. This feature allows using visual-box values to configure the reference box that defines the overflow clip edge the content is clipped to.
overflow-clip-margin
visual-box
Web Custom Formats lets websites read and write arbitrary unsanitized payloads using a standardized web custom format, as well as read and write a limited subset of OS-specific formats (for supporting legacy apps). The name of the clipboard format is mangled by the browser in a standardized way to indicate that the content is from the web. This allows platform applications to opt-in to accepting the unsanitized content.
Some web app developers want to exchange data payloads between web and platform applications via operating system clipboards. The Clipboard API supports the most popular standardized data types (text, image, rich text) across all platforms. However, this API does not scale to the long tail of specialized formats. In particular, custom formats, non-web-standard formats like TIFF (a large image format), and proprietary formats like docx (a document format), are not supported by the current Web Platform.
docx
As per the spec, Chromium's implementation of WebGL now allows specifying:
Before this version of Chrome, both of these defaulted to sRGB. Now they can also use "display-p3".
This version of Chrome introduces the deprecations and removals listed below. Visit ChromeStatus.com for lists of current deprecations and previous removals.
iframes can no longer navigate to filesystem URLs. Top frame support for navigating to filesystem URLs was dropped in Chrome 68.
Four client hints (dpr, width, viewport-width, and device-memory) have a default allowlist of self but behave as though they have a default allowlist of * on Android, contrary to the spec. This is now fixed, increasing privacy on Android by requiring explicit delegation of these hints.
dpr
width
viewport-width
device-memory
self
*
Chrome's legacy U2F API for interacting with security keys is no longer supported. U2F security keys themselves are not deprecated and will continue to work.
Affected sites should migrate to the Web Authentication API. Credentials that were originally registered via the U2F API can be challenged via web authentication. USB security keys that are supported by the U2F API are also supported by the Web Authentication API.
U2F is Chrome's original security key API. It allows sites to register public key credentials on USB security keys and challenge them for building phishing-resistant two-factor authentication systems. U2F never became an open web standard and was subsumed by the Web Authentication API (launched in Chrome 67). Chrome never directly supported the FIDO U2F JavaScript API, but rather shipped a component extension called cryptotoken, which exposes an equivalent chrome.runtime.sendMessage() method. U2F and Cryptotoken are firmly in maintenance mode and have encouraged sites to migrate to the Web Authentication API for the last two years.
chrome.runtime.sendMessage()
Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 103 is beta as of May 26, 2022. You can download the latest on Google.com for desktop or on Google Play Store on Android.
Chrome now supports the 103 Early Hints HTTP response code for navigation. (Note: the correspondence with the Chrome release number is a coincidence.) When a 103 response includes <link rel=preload> or other link headers Chromium tries to preload (and/or preconnect, prefetch) specified resources before the final response is received. This gives web developers a way to optimize core web vitals such as Largest Contentful Paint (LCP).
<link rel=preload>
HTTP/2 introduced the concept of server push, a mechanism that allows a server to preemptively send data to the client. Server push was intended to improve site performance. In the years since, developers have generally preferred preloading from the client side of a web interaction. 103 early hints for navigation provides a new way to do that.
For information on the work that went into bringing this to the web, see Beyond Server Push: The 103 Early Hints Status Code.
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.
The Federated Credential Management API allows users to log in to websites with their federated accounts in a privacy preserving manner. It allows the browser to understand the context in which the relying party and identity provider exchange information, inform the user about the information and privilege levels being shared and prevent unintended abuse. For more information, see Participate in a Federated Credential Management API origin trial for IdPs.
Web applications can now enumerate local fonts and metadata about each. The new API also gives web applications access to table data stored within local fonts, allowing those fonts to be rendered within their applications using custom text stacks.
Note: The Chrome 102 beta post erroneously listed this feature as shipping in that version.
Prerendering loads a web page before it is needed, so that when the actual navigation to that page occurs, it can be shown instantly. To speed up page loads. Chrome's previous prerender mechanism is now replaced with No State Prefetch. No State Prefetch doesn't generally result in an instant page load experience, but the new feature does. This feature is supported on Android only.
The implementation of GREASE in User Agent Client Hints is now aligned with the current spec, which includes additional GREASE characters beyond the current semicolon and space, and which recommends varying the arbitrary version. This helps prevent bad assumptions from being built on top of User-Agent strings.
GREASE
Returns a new AbortSignal object that is automatically aborted after a given number of milliseconds. Use this method to easily implement timeouts for signal-accepting asynchronous APIs, such as fetch(). For example: fetch(url, { signal: AbortSignal.timeout(10_000) });
fetch()
fetch(url, { signal: AbortSignal.timeout(10_000) });
The Element and ElementInternal interfaces now include an ARIA property called ariaRoleDescription which returns or modifies the ARIA role attribute directly. This feature is only supported on desktop.
Element
ElementInternal
ARIA
The avif image file format is now sharable by Web Share. Adding avif to the other allowed image file types helps spread the use of it. A website might like their users to be able to share pictures and other files through social media, email, chat, etc. The Web Share API is already shipped to more platforms such as ChromeOS and Windows, but avif is not supported yet.
Chrome supports a new compression format, deflate-raw, to give web developers access to the raw deflate stream without any headers or footers. This is needed, for example, to read and write zip files.
deflate-raw
The 'rel' attribute has been added to form elements. This makes it possible to prevent window.opener from being present on websites navigated to by form elements which have rel=noopener. It also prevents the referer header from being sent with rel=noreferrer.
'rel'
window.opener
rel=noopener
referer
rel=noreferrer
Chromium now matches Firefox and by firing popstate immediately after URL changes so that the order of events is now popstate then hashchange across both platforms. Before this change, Chromium fired hashchange asynchronously after a task, and delayed popstate until the load event. This means the event order could be either hashchange then popstate, or popstate then hashchange, depending on how long a document took to load.
popstate
hashchange
The Gampepad API now requires a secure context. Additionally a new feature policy called 'gamepad' has been added with a default allowlist of 'self'.
'gamepad'
The SerialPort forget() method allows web developers to voluntarily revoke a permission to a serial port that was granted by a user. Some sites may not be interested in retaining long-term permissions to access serial ports. For example, for an educational web application used on a shared computer with many devices, a large number of accumulated user-generated permissions creates a poor user experience. In addition to user agent mitigations to avoid this problem, such as defaulting to a session scoped permission on the first request or expiring infrequently used permissions, it should be possible for the site itself to clean up user-generated permissions it no longer needs.
SerialPort forget()
This follows the recent additions of a forget() method for the HIDDevice and USBDevice interfaces.
forget()
HIDDevice
USBDevice
The overflow-clip-margin CSS property now supports visual-box, which specifies the box edge to use as the overflow clip edge origin. Valid values are content-box, padding-box (the default), or border-box. The overflow-clip-margin property specifies how far an element's content is allowed to paint before being clipped.
content-box
padding-box
border-box
A user activation requirement has been added for Secure Payment Confirmation credential enrollment in a cross-origin iframe. This is being done to help mitigate a privacy issue.
Sandboxed iframes are not blocked from opening external applications. Currently, developers sandbox untrusted content and block user navigation. Blocking probably should have also included links to external apps or to the Play store. This has now been fixed.
Sites that need navigation can add the following values to the <iframe> element's sandbox property:
<iframe>
allow-popups
allow-top-navigation
allow-top-navigation-with-user-activation
The Battery Status API is no longer supported on insecure contexts, specifically HTTP pages and HTTPS iframes embedded in HTTP pages. This is being removed in accordance with our policy of deprecating powerful features on insecure origins, This also follows a spec change.
Given the removal of plugins from the web platform, and the relative lack of use of <param>, it is being removed from the web platform.
<param>
Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 102 is beta as of April 28, 2022. You can download the latest on Google.com for desktop or on Google Play Store on Android.
Window controls overlay extends an app's client area to cover the entire window, including the title bar, and the window control buttons (close, maximize/restore, minimize). The web app developer is responsible for drawing and input handling for the entire window except for the window controls overlay. Developers can use this feature to make their installed desktop web apps look like operating system apps. For more information, see Customize the window controls overlay of your PWA's title bar.
The following features, previously in a Chrome origin trial, are now enabled by default. 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.
A new mechanism allows an application to opt-in to exposing information to applications that are video-capturing it. This allows collaboration between capturing and captured applications. For example, a video conference application that's video-capturing a presentation, could expose user-facing controls in the video conference tab for navigating the presentation in the captured tab.
Network state is now partitioned by the network partition key (which consists of top frame site and possibly frame site), to protect against cross-site tracking through the use of side channels. "Network State" here includes connections (H1, H2, H3, websocket), the DNS cache, ALPN/H2 support data, TLS/H3 resumption information, Reporting/NEL configuration and uploads, and Expect-CT information. Cross-site tracking is a major privacy concern for users. This is a necessary part of addressing the problem.
Speculation rules provides a flexible syntax for defining what outgoing links are eligible to be prefetched before navigation. It also enables additional enhancements, such as use of a private prefetch proxy, where applicable.
This feature provides a new approach to loading a large number of resources efficiently using a format that allows multiple resources to be bundled, e.g. Web Bundles.
File Handling provides a way for web applications to declare the ability to handle files with given MIME types and extensions. The web application will receive an event when the user intends to open a file with that web application.
To define a PWA as a file handler, add the file_handlers member to the Web App Manifest. You can read about its members in the spec.
file_handlers
The new inert attribute lets you mark parts of the DOM tree as inert. When a node is inert:
inert
pointer-events
'none'
user-select
For more information, see Introducing inert.
Notes: This feature actually shipped in 103 instead of 102 as originally reported.
The new Navigation interface (accessible on window) lets apps intercept and initiate navigations, and introspect an application's history entries. This provides a more useful alternative to window.history and window.location specifically aimed at the needs of single-page web applications.
Navigation
window.history
window.location
Chrome adds a new value, until-found, for the hidden attribute, which makes an element searchable by find-in-page, scroll to text fragment, and fragment navigation. When these search/navigation features want to scroll to something inside a hidden=until-found element, the browser removes the hidden attribute from the element and fires the beforematch event on it so that the newly revealed content can be scrolled into view. For more information, see Making collapsed content accessible with hidden=until-found - Chrome Developers.
until-found
hidden
hidden=until-found
beforematch
The Origin Private File System (part of the File System Access API) is augmented with a new surface that improves the performance of data access. This new surface differs from existing ones by offering in-place and exclusive write access to a file's content. This change, along with the ability to consistently read unflushed modifications and the availability of a synchronous variant on dedicated workers, significantly improves performance and unblocks new use cases.
A CORS preflight request is now sent ahead of schedule for private network requests for subresources, requesting explicit permission from the target server. If the preflight fails, a warning is displayed in DevTools but the request proceeds as before. This is not expected to be a breaking change. Websites whose servers ignore or fail the new preflight request will continue to work as before.
A private network request is any request from a public website to a private IP address or localhost, or from a private website (e.g. intranet) to localhost. Sending a preflight request mitigates the risk of cross-site request forgery attacks against private network devices such as routers, which are often not prepared to defend against this threat.
This release contains three changes to the Secure Payment Confirmation API, specifically to the data passed to the PaymentMethod() constructor.
PaymentMethod()
data.rpId
data.instrument.iconMustBeShown
data.payeeName
data.payeeOrigin
The options object passed HID.requestDevice() now includes an exclusionFilters property. (HID is accessed via navigator.hid.) This property lets you exclude some devices from the browser picker. You can use it to exclude devices that are known to be malfunctioning. Previously, developers had to test a selected device with custom code, then ask the user to pick another if the selected device did not work. The exclusionFilters property (you will need to search for that term in the text) is an array of objects with the same members as the existing options.
HID.requestDevice()
navigator.hid
Here's an example of how to use the requestDevice() options argument. The example first requests access to a device with vendor ID 0xABCD. The device must also have a collection with usage page Consumer (0x000C) and usage ID Consumer Control (0x0001). The device with product ID 0x1234 is malfunctioning.
const [device] = await navigator.hid.requestDevice({ filters: [{ vendorId: 0xabcd, usagePage: 0x000c, usage: 0x0001 }], exclusionFilters: [{ vendorId: 0xabcd, productId: 0x1234 }], });
Sites can no longer call PaymentRequest.show() without a user activation. Allowing PaymentRequest.show() to be triggered without a user activation could be abused by malicious websites. To protect users, the spec was changed to require user activation. To avoid a broken purchase experience, calls to this method should now be inside a user event such as click.
PaymentRequest.show()
click
Firefox has not shipped PaymentRequest at all, while Safari's implementation already requires user activation for calling show().
PaymentRequest
show()
The Session Description Protocol (SDP) used to establish a session in WebRTC has been implemented with two different dialects in Chromium: Unified Plan and Plan B. Plan B is not cross-browser compatible and is hereby removed.
In this version of Chrome an exception will be thrown when Plan B is used. Developers needing to avoid the exception can participate in a deprecation trial until May 25, 2022. If you participated in the previous deprecation trial that ended in December, and want to participate in the current trial, you will need to request a new token.
Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 101 is beta as of March 31, 2022. You can download the latest on Google.com for desktop or on Google Play Store on Android.
Chrome is trying to reduce the amount of information the user agent string exposes in HTTP requests as well as in navigator.userAgent, navigator.appVersion, and navigator.platform. We're doing this to prevent the user agent string from being used for passive user fingerprinting. To join the origin trial, see its entry on Chrome Origin Trials. See the end of this article for additional deprecations and removals.
navigator.userAgent
navigator.appVersion
navigator.platform
This version of Chrome introduces the origin trial 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.
Federated Credential Management API (FedCM) aims to create privacy-preserving identity federation and is designed to make identity federation continue to allow use cases without the need for cross-site tracking such as third-party cookies. This feature starts its origin trial in 101 on Android only. We expect to add desktop support in Chrome 102.
The following feature, previously in a Chrome origin trial, is now enabled by default.
Priority Hints provides a way to indicate a resource's relative importance to the browser, allowing more control over the order resources are loaded.
AudioContext.outputLatency property is an estimation in seconds of the interval between when the user agent requests a host system to play a buffer and when the first sample in the buffer is processed by the audio output device. For devices such as speakers or headphones that produce an acoustic signal, 'processed by the audio output device' refers to the time when a sample's sound is produced. This property helps developers compensate for the latency between the input and the output. It's also useful for synchronization of video and audio streams.
AudioContext.outputLatency
This property is already implemented in Firefox.
The font-palette CSS property allows selecting a palette from a color font. In combination with the @font-palette-values at-rule, custom palettes can be defined. This feature is useful in designs where an icon or emoji font is used with dark or light mode, or when using multi-colored icon fonts that use the font-palette to harmonize with the content's color scheme.
font-palette
@font-palette-values
at-rule
HWB (short for 'hue whiteness blackness') is another method of specifying sRGB colors, similar to HSL, but often even easier for humans to work with. The hwb() function specifies HWB values in CSS. The function takes three arguments. The first, hue, specifies hue in degrees (not constrained to the range [0, 360]). The next two, whiteness and blackness, are specified as percentages.
hwb()
hue
whiteness
blackness
This feature follows a recent change to the spec for parsing the popup argument for window.open(). Previously, when popup was set equal to true, window.open() was interpreted to mean false. This is counterintuitive and confusing. This change makes boolean features easier to use and understand.
popup
window.open()
The MediaCapabilities API has been extended to support WebRTC streams. The MediaCapabilities API helps websites make informed decisions on what codec, resolution, etc. to use for video playback by indicating whether a configuration is supported and also whether the playback is expected to be smooth. Without this feature, web apps need to guess about suitable configurations. This can result in poor quality such as when an application uses low resolution or frame rates unnecessarily, or stuttering when the frame rate is too high.
The following features from version three of the Secure Payment Confirmation API are now implemented:
payeeName
The USBDevice forget() method allows web developers to voluntarily revoke a permission to a USBDevice that was granted by a user.
USBConfiguration, USBInterface, USBAlternateInterface, and USBEndpoint instances are now only strictly equal ("===") when they are retrieved from accessors on the same USBDevice.
USBConfiguration
USBInterface
USBAlternateInterface
USBEndpoint
WebSQL in third-party contexts is now removed. The Web SQL Database standard was first proposed in April 2009 and abandoned in November 2010. Gecko never implemented this feature and WebKit deprecated it in 2019. The W3C encourages Web Storage and Indexed Database for those needing alternatives.
Developers should expect that WebSQL itself will be deprecated and removed when usage is low enough.
