Chrome 87 is beta as of October 15, 2020.</p> <h2>WebAuthn Tab in DevTools</h2> <p>Testing web authentication has long been difficult because developers need devices to test their code. Starting in Chrome 87, authentication can be emulated and debugged using a new panel in DevTools. You can find the panel in DevTools by selecting <strong>More options</strong>, then <strong>More tools</strong>, then <strong>WebAuthn</strong>. To learn how to use it, see the section in <a href="https://developers.google.com/web/updates/2020/10/devtools#webauthn">What's New in DevTools (Chrome 87)</a>.</p> <p><span id="docs-internal-guid-9e3d9bb3-7fff-171d-f7d8-cc1b47dd6a5c"><span style="font-family: Arial; font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><span style="border: none; display: inline-block; height: 399px; overflow: hidden; width: 624px;"><img height="399" src="https://lh3.googleusercontent.com/24rUeaeOXh0gI5GYDqzM4VKnIbKNU6UOtlJKpilFZgJlSfCQhhJW1yk3Bzk42zLJ_iReS73Fh6loZTCH-bzF7Hk4FI-GJz9RiBsGOo_Ap6el9lYnvA3FJx7WmZSM3KHs62XAj6LYmw" style="margin-left: 0px; margin-top: 0px;" width="624" /></span></span></span></p> <h2>Control camera pan, tilt, and zoom</h2> <p>Room-scale video conferencing solutions deploy cameras with pan, tilt, and zoom capabilities so that software can point the camera at meeting participants. Starting in Chrome 87, the pan, tilt, and zoom features on cameras are accessible to websites using media track constraints in <code>MediaDevices.getUserMedia()</code> and <code>MediaStreamTrack.applyConstraints()</code>.</p> <p>Websites are only allowed to control these capabilities when users explicitly grant permission. For details on using the new capabilities and a demo, see <a href="https://web.dev/camera-pan-tilt-zoom/">Control camera pan, tilt, and zoom</a>.</p> <video autoplay="" controls="" muted=""> <source src="https://storage.googleapis.com/web-dev-assets/camera-pan-tilt-zoom/ptz_h264.mp4" type="video/mp4"> </video> <h2>CSS flow-relative shorthand and offset properties</h2> <p>The trend in CSS for many years has been to supplement physical properties with logical properties. Properties that assume language flows left to right and top to bottom don't work in non-European text such as vertical Chinese text, or Arabic. Modern CSS rules use flow-relative terms like start and end and provide rules for dealing with the text's axis (direction). </p> <p>The first step in implementing this in Chrome was to implement the most granular flow-relative features of the <a href="https://www.w3.org/TR/css-logical-1">CSS Logical Properties and Values</a> spec. Chrome 87 ships shorthands and <br /> offsets to make these logical properties and values a bit easier to write. What was once written with multiple CSS rules can now be written as one. For example, separate rules for <code>margin-block-start</code> and <code>margin-block-end</code> may now be written using a single <code>margin-block</code> property. </p> <p>For a list of all flow-relative shorthands now supported by Chrome, and explanations for how to use them, see <a href="https://web.dev/logical-property-shorthands/">Logical layout enhancements with flow-relative shorthands</a>. For more CSS-related updates, see the CSS section, below.</p> <h2>Completed Origin Trials</h2> <p>Origin trials allow you to try new features and give feedback on usability, practicality, and effectiveness to the web standards community. The following feature, previously in a Chrome origin trial, is now enabled by default.</p> <h4 style="text-align: left;">Cookie Store API</h4> <p>The Cookie Store API <a href="https://www.chromestatus.com/feature/5658847691669504">exposes HTTP cookies to service workers</a> and offers an asynchronous alternative to <code>document.cookie</code>.</p> <h2>Other features in this release</h2> <h4 style="text-align: left;">cross-origin isolation</h4> <p>Chrome 87 has a number of changes related to cross-origin isolation. Chrome will now use origin instead of site as agent cluster key for cross-origin isolated agent clusters. Mutation of <code>document.domain</code> is no longer supported for cross-origin isolated agent clusters. This change also introduces <code>window.crossOriginIsolated</code>, a boolean that indicates whether APIs that require cross-origin isolation are allowed to use it. Supporting APIs include:</p> <ul> <li><code><a href="https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer">SharedArrayBuffer</a></code> (required for WebAssembly Threads)</li> <li><code><a href="https://web.dev/monitor-total-page-memory-usage/">performance.measureMemory()</a></code></li> <li><a href="https://wicg.github.io/js-self-profiling/">JS Self-Profiling API</a></li> </ul> <p>For more information, see <a href="https://web.dev/coop-coep/">Making your website "cross-origin isolated" using COOP and COEP</a>.</p> <h4 style="text-align: left;">iframe attribute for limiting same-origin iframe document access</h4> <p>Adds <a href="https://www.chromestatus.com/feature/5648946183536640">the <code>disallowdocumentaccess</code> property</a> to disallow cross-document scripting between iframes from the same origin in the same parent document. This also puts same-origin iframes in separate event loops.</p><p><b>Note:</b> This item was pulled from Chrome 87 beta and was not in later builds.</p> <h4 style="text-align: left;">isInputPending()</h4> <p>Sometimes long-running scripts block user input. A lag between a user's action and a response by an app is a bad user experience. To address this, Chrome has added a method called <code>isInputPending()</code>, accessible from <code>navigator.scheduling</code>, which can be called from long-running operations. You can find <a href="https://wicg.github.io/is-input-pending/#examples-of-usage">an example of the method's use</a> in the draft spec.</p> <h4 style="text-align: left;">Range Request Headers in Service Workers</h4> <p>HTTP range requests, which have been available in major browsers for several years, allow servers to send requested data to the client in chunks. This has proved especially useful for large media files where the user experience is improved through smoother playback and improved pause and resume functions.</p> <p>Historically, range requests and services workers did not work well together, forcing developers to build <a href="https://code-tree.github.io/sw-partial-content/">work-arounds</a>. Starting in Chrome 87, passing range requests through to the network from inside a service worker will "just work."</p> <p>For an explanation of the issues with range requests and what's changed in Chrome 87, see <a href="https://web.dev/sw-range-requests/">Handling range requests in a service worker</a>.</p> <h4 style="text-align: left;">Streams API: transferable streams</h4> <p><a href="https://www.chromestatus.com/feature/5298733486964736">Transferable streams</a> now allows <code>ReadableStream</code>, <code>WritableStream</code>, and <code>TransformStream</code> objects to be passed as arguments to <code>postMessage()</code>. The streams APIs provide ubiquitous, interoperable primitives for creating, composing, and consuming streams of data. A natural thing to do with a stream is to pass it to a web worker. This provides a fluent primitive for offloading work to another thread. </p> <p>Offloading work onto a worker is important for a smooth user experience, but the ergonomics can be awkward. Transferable streams solve this problem for streams. Once the stream itself has been transferred, the data is transparently cloned in the background.</p> <h4 style="text-align: left;">Transition related event handlers</h4> <p>The <code>ontransitionrun</code>, <code>ontransitionstart</code>, and <code>ontransitioncancel</code> <a href="https://www.chromestatus.com/feature/5354694014664704">event handler attributes</a> allow developers to add event listeners for <code>'transitionrun'</code>, <code>'transitionstart'</code>, and <code>'transitioncancel'</code> events on elements, Document objects, and Window objects.</p> <h4 style="text-align: left;">WakeLockSentinel.released Attribute</h4> <p>The <code><a href="https://developer.mozilla.org/en-US/docs/Web/API/WakeLockSentinel">WakeLockSentinel</a></code> object has <a href="https://www.chromestatus.com/feature/5632527123349504">a new property called <code>released</code></a> that indicates whether a sentinel has already been released. It defaults to false and changes to true when a release event is dispatched. The new attribute helps web developers know when locks are released so that they do not need to keep track of them manually. </p> <h3>CSS</h3> <h4>@font-face descriptors to override font metrics</h4> <p>New <a href="https://www.chromestatus.com/feature/5651198621253632"><code>@font-face</code> descriptors</a> have been added to <code>ascent-override</code>, <code>descent-override</code>, and <code>line-gap-override</code> to override metrics of the font. This Improves interoperably across browsers and operating systems, so that the same font always looks the same on the same site, regardless of OS or browser. Additionally, it aligns metrics between two web fonts present simultaneously, but for different glyphs. Finally, it overrides font metrics for a fallback font to emulate a web font, to minimize cumulative layout shift.</p> <h4>Text Decoration and Underline Properties</h4> <p>Chrome now supports <a href="https://www.chromestatus.com/feature/5747636764147712">several new text decoration and underline properties</a>. These properties solve use cases where underlines are too close to the text baseline and ink-skipping triggers too early in a text run. These use cases solve problems caused by the launch of the <code><a href="https://developer.mozilla.org/en-US/docs/Web/CSS/text-decoration-skip-ink">text-decoration-skip-ink </a></code>property. The new properties are <code>text-decoration-thickness</code>, <code>text-underline-offset</code> and a <code>from-font</code> keyword for <code>text-underline-position</code>.</p> <h4>The quotes Property Supports the 'auto' Value</h4> <p>CSS2 allowed browsers to define the default value for the quotes property, which Chrome formerly followed. Chrome 87 <a href="https://www.chromestatus.com/feature/4922661488558080">now follows CSS Generated Content Module Level 3</a> in which the <code>'auto'</code> keyword is the default value. That spec requires that a typographically appropriate value be used for quotes based on the content language of the element and/or its parent.</p> <h3>JavaScript</h3> <p>This version of Chrome incorporates version 8.7 of the V8 JavaScript engine. It specifically includes the changes listed below. You can find a complete <a href="https://v8.dev/blog">list of recent features</a> in the V8 release notes.</p> <h4>Atomics.waitAsync()</h4> <p><a href="https://www.chromestatus.com/feature/6243382101803008">Chrome now supports <code>Atomics.waitAsync()</code></a>, the async version of <code>Atomics.wait()</code>. <code>Atomics.waitAsync()</code> allows programmers to wait on a <code>SharedArrayBuffer</code> location in the same fashion as <code>Atomics.wait()</code> but returns a Promise instead.</p> <p><code>Atomics.wait()</code> blocks the thread and cannot be used on the main web browser thread, where blocking is disallowed. This makes coordination via <code>SharedArrayBuffers</code> between the main thread and worker threads more ergonomic.</p> <h3 style="text-align: left;">Deprecations and Removals</h3> <p>This version of Chrome introduces the deprecations and removals listed below. Visit ChromeStatus.com for lists of <a href="https://www.chromestatus.com/features#browsers.chrome.status%3A%22Deprecated%22">current deprecations</a> and <a href="https://www.chromestatus.com/features#browsers.chrome.status:%22Removed%22">previous removals</a>.</p> <h4 style="text-align: left;">Comma separator in iframe allow attribute</h4> <p>Permissions policy declarations in an <code><iframe></code> tag <a href="https://www.chromestatus.com/feature/5740835259809792">can no longer use commas</a> as a separator between items. Developers should use semicolons instead.</p> <h4 style="text-align: left;">-webkit-font-size-delta</h4> <p>Blink <a href="https://www.chromestatus.com/feature/6267981828980736">will no longer support</a> the rarely-used <code>-webkit-font-size-delta</code> property. Developers should use <code>font-size</code> to control font size instead.</p> <h4 style="text-align: left;">Deprecate FTP support</h4> <p>Chrome is <a href="https://www.chromestatus.com/features/6246151319715840">deprecating and removing support for FTP URLs</a>. The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), nor proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition, more capable FTP clients are available on all affected platforms.<br /> <br /> Google Chrome 72 and later removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs results in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74 and later resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76. In Chrome 86, FTP was turned off for pre-release channels (Canary and Beta) and was experimentally turned off for one percent of stable users. <br /> <br /> The remaining capabilities of Google Chrome's FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections. </p> <p>Remainder of the deprecation follows this timeline:</p> <h4>Chrome 87</h4> <p>FTP support will be disabled by default for fifty percent of users but can be enabled using the flags listed above.</p> <h4>Chrome 88</h4> <p>FTP support will be disabled.</p> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <p>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 <a href="https://www.chromestatus.com/features#milestone%3D76">ChromeStatus.com</a>. Chrome 87 is beta as of October 15, 2020.</p> <h2>WebAuthn Tab in DevTools</h2> <p>Testing web authentication has long been difficult because developers need devices to test their code. Starting in Chrome 87, authentication can be emulated and debugged using a new panel in DevTools. You can find the panel in DevTools by selecting <strong>More options</strong>, then <strong>More tools</strong>, then <strong>WebAuthn</strong>. To learn how to use it, see the section in <a href="https://developers.google.com/web/updates/2020/10/devtools#webauthn">What's New in DevTools (Chrome 87)</a>.</p> <p><span id="docs-internal-guid-9e3d9bb3-7fff-171d-f7d8-cc1b47dd6a5c"><span style="font-family: Arial; font-size: 11pt; font-variant-east-asian: normal; font-variant-numeric: normal; vertical-align: baseline; white-space: pre-wrap;"><span style="border: none; display: inline-block; height: 399px; overflow: hidden; width: 624px;"><img height="399" src="https://lh3.googleusercontent.com/24rUeaeOXh0gI5GYDqzM4VKnIbKNU6UOtlJKpilFZgJlSfCQhhJW1yk3Bzk42zLJ_iReS73Fh6loZTCH-bzF7Hk4FI-GJz9RiBsGOo_Ap6el9lYnvA3FJx7WmZSM3KHs62XAj6LYmw" style="margin-left: 0px; margin-top: 0px;" width="624" /></span></span></span></p> <h2>Control camera pan, tilt, and zoom</h2> <p>Room-scale video conferencing solutions deploy cameras with pan, tilt, and zoom capabilities so that software can point the camera at meeting participants. Starting in Chrome 87, the pan, tilt, and zoom features on cameras are accessible to websites using media track constraints in <code>MediaDevices.getUserMedia()</code> and <code>MediaStreamTrack.applyConstraints()</code>.</p> <p>Websites are only allowed to control these capabilities when users explicitly grant permission. For details on using the new capabilities and a demo, see <a href="https://web.dev/camera-pan-tilt-zoom/">Control camera pan, tilt, and zoom</a>.</p> <video autoplay="" controls="" muted=""> <source src="https://storage.googleapis.com/web-dev-assets/camera-pan-tilt-zoom/ptz_h264.mp4" type="video/mp4"> </video> <h2>CSS flow-relative shorthand and offset properties</h2> <p>The trend in CSS for many years has been to supplement physical properties with logical properties. Properties that assume language flows left to right and top to bottom don't work in non-European text such as vertical Chinese text, or Arabic. Modern CSS rules use flow-relative terms like start and end and provide rules for dealing with the text's axis (direction). </p> <p>The first step in implementing this in Chrome was to implement the most granular flow-relative features of the <a href="https://www.w3.org/TR/css-logical-1">CSS Logical Properties and Values</a> spec. Chrome 87 ships shorthands and <br /> offsets to make these logical properties and values a bit easier to write. What was once written with multiple CSS rules can now be written as one. For example, separate rules for <code>margin-block-start</code> and <code>margin-block-end</code> may now be written using a single <code>margin-block</code> property. </p> <p>For a list of all flow-relative shorthands now supported by Chrome, and explanations for how to use them, see <a href="https://web.dev/logical-property-shorthands/">Logical layout enhancements with flow-relative shorthands</a>. For more CSS-related updates, see the CSS section, below.</p> <h2>Completed Origin Trials</h2> <p>Origin trials allow you to try new features and give feedback on usability, practicality, and effectiveness to the web standards community. The following feature, previously in a Chrome origin trial, is now enabled by default.</p> <h4 style="text-align: left;">Cookie Store API</h4> <p>The Cookie Store API <a href="https://www.chromestatus.com/feature/5658847691669504">exposes HTTP cookies to service workers</a> and offers an asynchronous alternative to <code>document.cookie</code>.</p> <h2>Other features in this release</h2> <h4 style="text-align: left;">cross-origin isolation</h4> <p>Chrome 87 has a number of changes related to cross-origin isolation. Chrome will now use origin instead of site as agent cluster key for cross-origin isolated agent clusters. Mutation of <code>document.domain</code> is no longer supported for cross-origin isolated agent clusters. This change also introduces <code>window.crossOriginIsolated</code>, a boolean that indicates whether APIs that require cross-origin isolation are allowed to use it. Supporting APIs include:</p> <ul> <li><code><a href="https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer">SharedArrayBuffer</a></code> (required for WebAssembly Threads)</li> <li><code><a href="https://web.dev/monitor-total-page-memory-usage/">performance.measureMemory()</a></code></li> <li><a href="https://wicg.github.io/js-self-profiling/">JS Self-Profiling API</a></li> </ul> <p>For more information, see <a href="https://web.dev/coop-coep/">Making your website "cross-origin isolated" using COOP and COEP</a>.</p> <h4 style="text-align: left;">iframe attribute for limiting same-origin iframe document access</h4> <p>Adds <a href="https://www.chromestatus.com/feature/5648946183536640">the <code>disallowdocumentaccess</code> property</a> to disallow cross-document scripting between iframes from the same origin in the same parent document. This also puts same-origin iframes in separate event loops.</p><p><b>Note:</b> This item was pulled from Chrome 87 beta and was not in later builds.</p> <h4 style="text-align: left;">isInputPending()</h4> <p>Sometimes long-running scripts block user input. A lag between a user's action and a response by an app is a bad user experience. To address this, Chrome has added a method called <code>isInputPending()</code>, accessible from <code>navigator.scheduling</code>, which can be called from long-running operations. You can find <a href="https://wicg.github.io/is-input-pending/#examples-of-usage">an example of the method's use</a> in the draft spec.</p> <h4 style="text-align: left;">Range Request Headers in Service Workers</h4> <p>HTTP range requests, which have been available in major browsers for several years, allow servers to send requested data to the client in chunks. This has proved especially useful for large media files where the user experience is improved through smoother playback and improved pause and resume functions.</p> <p>Historically, range requests and services workers did not work well together, forcing developers to build <a href="https://code-tree.github.io/sw-partial-content/">work-arounds</a>. Starting in Chrome 87, passing range requests through to the network from inside a service worker will "just work."</p> <p>For an explanation of the issues with range requests and what's changed in Chrome 87, see <a href="https://web.dev/sw-range-requests/">Handling range requests in a service worker</a>.</p> <h4 style="text-align: left;">Streams API: transferable streams</h4> <p><a href="https://www.chromestatus.com/feature/5298733486964736">Transferable streams</a> now allows <code>ReadableStream</code>, <code>WritableStream</code>, and <code>TransformStream</code> objects to be passed as arguments to <code>postMessage()</code>. The streams APIs provide ubiquitous, interoperable primitives for creating, composing, and consuming streams of data. A natural thing to do with a stream is to pass it to a web worker. This provides a fluent primitive for offloading work to another thread. </p> <p>Offloading work onto a worker is important for a smooth user experience, but the ergonomics can be awkward. Transferable streams solve this problem for streams. Once the stream itself has been transferred, the data is transparently cloned in the background.</p> <h4 style="text-align: left;">Transition related event handlers</h4> <p>The <code>ontransitionrun</code>, <code>ontransitionstart</code>, and <code>ontransitioncancel</code> <a href="https://www.chromestatus.com/feature/5354694014664704">event handler attributes</a> allow developers to add event listeners for <code>'transitionrun'</code>, <code>'transitionstart'</code>, and <code>'transitioncancel'</code> events on elements, Document objects, and Window objects.</p> <h4 style="text-align: left;">WakeLockSentinel.released Attribute</h4> <p>The <code><a href="https://developer.mozilla.org/en-US/docs/Web/API/WakeLockSentinel">WakeLockSentinel</a></code> object has <a href="https://www.chromestatus.com/feature/5632527123349504">a new property called <code>released</code></a> that indicates whether a sentinel has already been released. It defaults to false and changes to true when a release event is dispatched. The new attribute helps web developers know when locks are released so that they do not need to keep track of them manually. </p> <h3>CSS</h3> <h4>@font-face descriptors to override font metrics</h4> <p>New <a href="https://www.chromestatus.com/feature/5651198621253632"><code>@font-face</code> descriptors</a> have been added to <code>ascent-override</code>, <code>descent-override</code>, and <code>line-gap-override</code> to override metrics of the font. This Improves interoperably across browsers and operating systems, so that the same font always looks the same on the same site, regardless of OS or browser. Additionally, it aligns metrics between two web fonts present simultaneously, but for different glyphs. Finally, it overrides font metrics for a fallback font to emulate a web font, to minimize cumulative layout shift.</p> <h4>Text Decoration and Underline Properties</h4> <p>Chrome now supports <a href="https://www.chromestatus.com/feature/5747636764147712">several new text decoration and underline properties</a>. These properties solve use cases where underlines are too close to the text baseline and ink-skipping triggers too early in a text run. These use cases solve problems caused by the launch of the <code><a href="https://developer.mozilla.org/en-US/docs/Web/CSS/text-decoration-skip-ink">text-decoration-skip-ink </a></code>property. The new properties are <code>text-decoration-thickness</code>, <code>text-underline-offset</code> and a <code>from-font</code> keyword for <code>text-underline-position</code>.</p> <h4>The quotes Property Supports the 'auto' Value</h4> <p>CSS2 allowed browsers to define the default value for the quotes property, which Chrome formerly followed. Chrome 87 <a href="https://www.chromestatus.com/feature/4922661488558080">now follows CSS Generated Content Module Level 3</a> in which the <code>'auto'</code> keyword is the default value. That spec requires that a typographically appropriate value be used for quotes based on the content language of the element and/or its parent.</p> <h3>JavaScript</h3> <p>This version of Chrome incorporates version 8.7 of the V8 JavaScript engine. It specifically includes the changes listed below. You can find a complete <a href="https://v8.dev/blog">list of recent features</a> in the V8 release notes.</p> <h4>Atomics.waitAsync()</h4> <p><a href="https://www.chromestatus.com/feature/6243382101803008">Chrome now supports <code>Atomics.waitAsync()</code></a>, the async version of <code>Atomics.wait()</code>. <code>Atomics.waitAsync()</code> allows programmers to wait on a <code>SharedArrayBuffer</code> location in the same fashion as <code>Atomics.wait()</code> but returns a Promise instead.</p> <p><code>Atomics.wait()</code> blocks the thread and cannot be used on the main web browser thread, where blocking is disallowed. This makes coordination via <code>SharedArrayBuffers</code> between the main thread and worker threads more ergonomic.</p> <h3 style="text-align: left;">Deprecations and Removals</h3> <p>This version of Chrome introduces the deprecations and removals listed below. Visit ChromeStatus.com for lists of <a href="https://www.chromestatus.com/features#browsers.chrome.status%3A%22Deprecated%22">current deprecations</a> and <a href="https://www.chromestatus.com/features#browsers.chrome.status:%22Removed%22">previous removals</a>.</p> <h4 style="text-align: left;">Comma separator in iframe allow attribute</h4> <p>Permissions policy declarations in an <code><iframe></code> tag <a href="https://www.chromestatus.com/feature/5740835259809792">can no longer use commas</a> as a separator between items. Developers should use semicolons instead.</p> <h4 style="text-align: left;">-webkit-font-size-delta</h4> <p>Blink <a href="https://www.chromestatus.com/feature/6267981828980736">will no longer support</a> the rarely-used <code>-webkit-font-size-delta</code> property. Developers should use <code>font-size</code> to control font size instead.</p> <h4 style="text-align: left;">Deprecate FTP support</h4> <p>Chrome is <a href="https://www.chromestatus.com/features/6246151319715840">deprecating and removing support for FTP URLs</a>. The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), nor proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition, more capable FTP clients are available on all affected platforms.<br /> <br /> Google Chrome 72 and later removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs results in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74 and later resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76. In Chrome 86, FTP was turned off for pre-release channels (Canary and Beta) and was experimentally turned off for one percent of stable users. <br /> <br /> The remaining capabilities of Google Chrome's FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections. </p> <p>Remainder of the deprecation follows this timeline:</p> <h4>Chrome 87</h4> <p>FTP support will be disabled by default for fifty percent of users but can be enabled using the flags listed above.</p> <h4>Chrome 88</h4> <p>FTP support will be disabled.</p> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Chromium Blog:Chrome 87 Beta: WebAuthn in DevTools, Pan/Tilt/Zoom, Flow Relative Shorthands and More&url=https://blog.chromium.org/2020/10/chrome-87-beta-webauthn-in-devtools.html&via=ChromiumDev'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://blog.chromium.org/2020/10/chrome-87-beta-webauthn-in-devtools.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://blog.chromium.org/2020/10/chrome-87-beta-webauthn-in-devtools.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://blog.chromium.org/search/label/beta' rel='tag'> beta </a> </span> </div> </div> </div> <div class='post' data-id='6264066038214312068' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://blog.chromium.org/2020/10/chrome-is-deploying-http3-and-ietf-quic.html' itemprop='url' title=' Chrome is deploying HTTP/3 and IETF QUIC'> Chrome is deploying HTTP/3 and IETF QUIC </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Wednesday, October 7, 2020 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> QUIC is a new networking transport protocol that combines the features of TCP, TLS, and more. HTTP/3 is the latest version of HTTP, the protocol that carries the vast majority of Web traffic. HTTP/3 only runs over QUIC.<br /><br /><br />QUIC was initially developed by Google and <a href="https://blog.chromium.org/2013/06/experimenting-with-quic.html">first announced in 2013</a>. Since then, the protocol has matured, and is now responsible for carrying over a third of Google traffic. In 2015, Google brought QUIC to the IETF (the standards organization responsible for maintaining the Internet's protocols) and the IETF has been improving QUIC by making many changes to it. At this point, there are now two similar but different protocols: Google QUIC and IETF QUIC. The QUIC team at Google has been involved in the IETF process from the start, but we've been using Google QUIC in Chrome while working on implementing IETF QUIC. We've put tremendous effort into evolving Google QUIC over the last five years to track changes at IETF, and the current latest Google QUIC version (Q050) has many similarities with IETF QUIC. But up until now, the majority of Chrome users didn't communicate with IETF QUIC servers without enabling some command-line options.<br /><br /><br />Today this changes. We've found that IETF QUIC significantly outperforms HTTP over TLS 1.3 over TCP. In particular, Google search latency decreases by over 2%. YouTube rebuffer time decreased by over 9%, while client throughput increased by over 3% on desktop and over 7% on mobile. We're happy to announce that Chrome is rolling out support for IETF QUIC (specifically, draft version h3-29). Today 25% of Chrome Stable users are using h3-29, and we plan on increasing that number over the coming weeks as we continue to monitor performance data. Chrome will actively support both IETF QUIC h3-29 and Google QUIC Q050 to provide servers that support Q050 with time to update to IETF QUIC.<br /><br /><br />Chrome m85 doesn't yet support IETF QUIC 0-RTT, so we expect these performance numbers to look even better once we launch 0-RTT support for IETF QUIC in the coming months.<br /><br /><br />Since the subsequent IETF drafts 30 and 31 do not have compatibility-breaking changes, we currently are not planning to change the over-the-wire identifier. What this means is that while we'll keep tracking changes in the IETF specification, we will be deploying them under the h3-29/0xff00001d name. We therefore recommend that servers keep support for h3-29 until the final RFCs are complete if they wish to interoperate with Chrome. However, if the IETF were to make compatibility-breaking changes in a future draft, Chrome will revisit this decision.<br /><br /><br />The authors would like to thank the entire QUIC team at Google for all their hard work leading up to this announcement. We're incredibly proud of what we've achieved together.

With Privacy Sandbox we’ve been exploring privacy-preserving mechanisms with the web community that protect user data and prevent intrusive cross-site tracking. Our aim is to preserve the vitality of the open web by continuing to enable the rich, quality content and services that people expect, but with even stronger guarantees of privacy and safety. Today we’re sharing progress on this long-term initiative and asking for your continued help in increasing the privacy of web browsing.<br /><br />In January we shared our intent to develop privacy-preserving open-standards that will render third-party cookies obsolete. Since then, <a href="https://www.chromium.org/Home/chromium-privacy/privacy-sandbox" target="_blank">Google</a> and <a href="https://github.com/w3c/web-advertising" target="_blank">others</a> have proposed several new APIs to address use cases like fraud protection, ad selection, and conversion measurement without allowing users’ activity to be tracked across websites.

With Privacy Sandbox we’ve been exploring privacy-preserving mechanisms with the web community that protect user data and prevent intrusive cross-site tracking. Our aim is to preserve the vitality of the open web by continuing to enable the rich, quality content and services that people expect, but with even stronger guarantees of privacy and safety. Today we’re sharing progress on this long-term initiative and asking for your continued help in increasing the privacy of web browsing.<br /><br />In January we shared our intent to develop privacy-preserving open-standards that will render third-party cookies obsolete. Since then, <a href="https://www.chromium.org/Home/chromium-privacy/privacy-sandbox" target="_blank">Google</a> and <a href="https://github.com/w3c/web-advertising" target="_blank">others</a> have proposed several new APIs to address use cases like fraud protection, ad selection, and conversion measurement without allowing users’ activity to be tracked across websites. Following web community input, some of these solutions are now available for experimental testing via <a href="https://web.dev/origin-trials/" target="_blank">Chrome origin trials</a>:<br /><ul style="text-align: left;"><li><span style="font-family: Roboto;"><a href="https://web.dev/conversion-measurement/" target="_blank">Click Conversion Measurement API </a>opened up for testing in September and aims to enable marketers to know whether an ad click resulted in a conversion (for example, a purchase or a sign-up) on another site, without connecting the identity of the user across both sites.</span></li></ul><ul style="text-align: left;"><li><a href="https://web.dev/trust-tokens/" target="_blank">Trust Tokens</a> opened up for testing in July and is intended to support a number of use cases evaluating a user’s authenticity, including combating fraud.</li></ul><br />If you integrate APIs into your products and services, you can <a href="https://developers.chrome.com/origintrials/#/trials/active" target="_blank">register</a> for access to these and other APIs through Chrome origin trials.
