This release of Chrome had 35 new features.

'formdata' event

The 'formdata' event enables any objects to provide form data. It helps avoid creating <input type=hidden> representing application state, or making submittable custom elements. #

Automatically lazily load below-the-fold iframes and images for Lite Mode users

Enables deferring the load of below-the-fold iframes and images pages until the user scrolls near them, without requiring actions by web developers. This helps to reduce network data and memory use, and may also increase site speed by prioritizing content that users are viewing. This feature is enabled for Chrome Lite Mode users only. #

Deprecate insecure Web MIDI use

Stop exposing Web MIDI API to insecure origins from Chrome 77. #

This feature was specified in this Spec.

Do not apply hover when mouse does not move

To update the hover state when a page scrolls or changes layout, Blink currently dispatches fake mouse moves based on a timer because the mouse does not move. Unfortunately, every mouse move does a hit test which affects both performance and testing. This change applies the hover effect only when a mouse physically moves, improving performance and eliminating issues created by fake mouse events. #

First Input Timing

The PerformanceEventTiming interface provides timing information about the latency of the first discrete user interaction, specifically one of key down, mouse down, click, a pointer down followed by a pointer up. (Pointer down may be the start of scrolling, which is not tracked.) This is a subset of the EventTiming API, but will be exposed in advance because it provides key metrics to help measure and optimize responsiveness. #

This feature was specified in this Spec.

Form-associated custom elements

Form-associated custom elements enable web authors to define and create custom elements which participate in form submission. #

Intervention: ignore input events targeting recently-moved iframes.

To prevent unintended clicks/taps, quietly discard input events that target cross-origin iframes that have recently resized or moved a non-trivial distance within the embedding page's viewport. The shipped version limits the intervention to cross-origin iframes that are using the V2 feature set of IntersectionObserver (https://github.com/w3c/IntersectionObserver/tree/v2). #

Largest contentful paint

Largest Contentful Paint (LCP) is a new page load metric available as a performance API, which describes page speed as the speed of delivering the largest contentful element to the screen. It is the high-level metric (where Element Timing is its low-level primitive) aiming to provide a meaningful result even for developers who don't annotate their sites. #

Lazily load iframes and images via ‘loading’ attribute

Support the ‘loading’ attribute, which can be used to defer the load of below-the-fold iframes and images on the page until the user scrolls near them. This is to reduce data usage, memory usage, and to speed up above-the-fold content. Web developers can opt-in to lazy load by specifying loading=lazy on <iframe> and <img> elements. #

Limit registerProtocolHandler() url argument to http/https

Limits registerProtocolHandler() to only accept URLs with http or https schemas. Because the intent of the API is to allow and endpoint to handle something like an SMS message, for example, it doesn't make much sense for handlers to be data URLs, blob URLs, or whatever. #

New TextMetrics object in canvas

The implementation of an extended API of text metrics started in 2014: https://groups.google.com/a/chromium.org/d/msg/blink-dev/SgofW_bQ3ps/jNYamQHplAMJ But was never shipped, and had multiple undefined values that were not addressed for years. The spec has now evolved and we intend to ship actualBoundingBoxLeft, actualBoundingBoxRight, actualBoundingBoxAscent and actualBoundingBoxDescent according to the current spec: https://html.spec.whatwg.org/multipage/canvas.html#textmetrics #

This feature was specified in this Spec.

Overscroll Behavior logical longhands

Adds CSS flow-relative properties for controlling overscroll behavior through logical dimensions. flow-relative properties are those that are interpreted relative to the flow of content. The new properties are overscroll-behavior-inline and overscroll-behavior-block. #

Partition the HTTP Cache

Splits the HTTP cache using the top frame site and subframe site (where site = scheme://etld+1) to prevent documents from one site from knowing whether a resource from another site was cached. The HTTP cache is currently one per profile, with a single namespace for all resources and subresources regardless of origin or renderer process. Splitting the cache on top frame site helps the browser deflect side-channel attacks where one site can detect resources in another site’s cache. #

Pointerrawupdate

Send pointerrawupdate events for move events as soon as they happen as oppose to pointermove events which are being rAF-aligned and hence may add half a frame of latency on average from when they happened until they are delivered to the javascript. #

Precise src: local() matching in CSS @font-faces by PostScript and Full Font Name

Precisely match locally installed fonts by PostScript name or full font name, when used in a local() value to a src: descriptor in a @font-face declaration. This means, you can precisely and uniquely select local fonts by specifying their PostScript name or full font name. Previously Blink had implemented this incorrectly and was using the specified font name to perform a family match. #

Preserve request priorities through service worker

Preserves a request’s original priority when it passes through a service worker. Previously, all requests going through a service worker would get "High" priority. This means render-blocking style sheets would have their priority clamped, while less-important resources would get boosted. The priority of network requests can be seen in the DevTools network tab. Render-blocking resources such as style sheets have "Highest" priority, while resources like async scripts have "Low" priority. #

Service workers support basic HTTP authentication

Displays HTTP authentication dialog boxes even if the request was from a service worker. This shows the native login dialog shown when an HTTP 401 response is received. Note: this requires the network service to be enabled, which is enabled by default on most platforms. #

This feature was specified in this Spec.

Stop action for Media Session

Adds support for the "stop" action to the MediaSession interface. An action is an event tied specifically to a common media function such as pause or play. The "stop" action handler is called when the site should stop the playback and clear the state if appropriate. #

Support step timing functions jump-start|end|both|none

The step timing functions jump-both, jump-none, jump-start and jump-end were introduced to the spec for easing functions in 2018. Two of these (jump-start and jump-end) are aliases for start and end. The remaining two provide increased flexibility for step transitions by enabling step functions in which both or neither endpoint has a discontinuous step. Previously, one and only one of the two endpoints could have a step discontinuity. #

tab-size supports css value type

Adds support for <number> css value type to the CSS property tab-size, which determines the tab size used to render preserved tab characters. 'tab-size' accepts an <integer> or a <number> as its value type, and represents the measure as a real-number multiple of the space character’s advance width, in addition to its integer multiple. #

Deprecations and Removals

Deprecation policy

To keep the platform healthy, we sometimes remove APIs from the Web Platform which have run their course. There can be many reasons why we would remove an API, such as:

Some of these changes will have an effect on a very small number of sites. To mitigate issues ahead of time, we try to give developers advanced notice so they can make the required changes to keep their sites running.

Chrome currently has a process for deprecations and removals of API's, essentially:

You can find a list of all deprecated features on chromestatus.com using the deprecated filter and removed features by applying the removed filter. We will also try to summarize some of the changes, reasoning, and migration paths in these posts.

Deprecated features in 77

This release of Chrome had 0 features deprecated.

Removed features in 77

This release of Chrome had 1 features removed.
