Software-update: Google Chrome 72.0.3626.81

Google Chrome logo, 2018 (80 pix) Google heeft versie 72 van zijn webbrowser Chrome uitgebracht. Google Chrome is beschikbaar voor Windows, Linux en macOS. Er zijn ook versies voor Android en iOS, maar die volgen een iets ander releaseschema. Sinds versie 50 is de ondersteuning voor oudere versies van Windows en macOS vervallen. De belangrijkste veranderingen in deze uitgave, naast de gebruikelijke bug- en security fixes, zijn hieronder voor je op een rijtje gezet.

Public class fields

Chrome now allows declaration of public class fields in scripts. This is the first part of class field declarations in JavaScript; support for private class fields is coming soon. To implement public class fields, declare them inside a class declaration but outside of any member functions. They can be either initialized or uninitialized.
Declaring class fields makes class definitions more self-documenting. Because these fields are always present, class instances go through fewer transitions. Head over to our article on class fields and the ChromeStatus entry for more information.

User Activation Query API

Chrome now provides an API for querying whether there has been a user activation. This is useful for APIs that are deliberately restricted to avoid annoying web page behaviors. Examples include requestFullScreen(), autoplay, and window.open(). This also allows embedded iframes to vet postMessage() calls to determine whether they occurred within the context of a user activation. The new userActivation property, available on both navigator and MessageEvent, supports the following properties:

  • hasBeenActive: Indicates whether the associated window has ever seen a user activation in its lifecycle. This property does not reflect whether the current task was triggered by a user activation.
  • isActive: Indicates whether the associated window currently has a user activation in its lifecycle.

The postMessage() method now also takes an options argument on the Window, Worker, and MessagePort objects. This object subsumes existing arguments and adds the includeUserActivation boolean property to notify the message recipient that there has been a user activation

Cache API: reject addAll() when requests would overwrite each other

The Cache.prototype.addAll() API, which allows multiple entries to be added to the cache at once, previously violated a specification requirement that each request/response pair avoid overwriting another entry being added in the same call. Chrome would resolve such conflicts by storing the later entry and ignoring the earlier one. Cache.prototype.addAll() now rejects with an InvalidStateError.

Intl.ListFormat
The new Intl.ListFormat() API helps libraries and frameworks format a list in a localized fashion by providing internationalized messages using a customary local word or phrase when available.

For more information, read our Web Fundamentals article.

FetchEvent.resultingClientId
FetchEvent.resultingClientId, set on navigation requests or requests for workers, is the ID of the client, either a document or a worker, and is created by the request. It's useful for associating the main resource request from a document with subsequent subresource requests from the same document, for example, for logging and metrics purposes.

FetchEvents on requests for same-origin favicons.
Previously, technical limitations prevented service workers from receiving FetchEvent objects for favicon requests. Now, service workers will receive FetchEvent objects as long as the request URL is on the same origin as the service worker.

MediaStreamTrack resizeMode constraint
A new property controls how the browser derives the resolution of a MediaStreamTrack. There are two supported values:

  • "none": the track has the native resolution provided by the camera, its driver, or the operating system.
  • "crop-and-scale": the browser may use cropping and re-scaling to adjust the resolution of the video produced by the camera.

This feature allows applications to improve consistency across browsers, and to use only native resolutions when desired.

RTCPeerConnection.connectionState and RTCPeerConnection.onconnectionstatechanged
Chrome now supports RTCPeerConnection.connectionState, which is an aggregate value computed from the transport states of the peerconnection's underlying ICE and DTLS transports. It's intended to provide a more complete overview of the connection state than RTCPeerConnection.iceConnectionState, which is only supposed to be based on the ICE transports.

Well-formed JSON.stringify
A Stage 3 ECMAScript proposal changes JSON.stringify() to prevent it from returning ill-formed Unicode strings. Previously, JSON.stringify() would output lone surrogates themselves if the input contained any. With this change, JSON.stringify() outputs escape sequences for lone surrogates, making its output valid Unicode (and representable in UTF-8). The example below demonstrates how this works in practice. JSON.stringify("\uD800");

  • Previously, this returned '"�"'
  • Starting in Chrome 72, this returns '"\ud800"'

Worker unhandled exception propagation
For dedicated workers, unhandled errors now propagate to the parent context and the error reporting process begins again one layer up (for example, to the window's onerror handler). This allows for errors to be propagated up to the original document, giving developers the freedom to choose when and how to handle worker errors.

Interoperability Improvements

Interoperable File.webkitRelativePath property
The File.webkitRelativePath of the File interface previously returned a value different from other major browsers, now it returns the same value.

Treat '#' as ending data URI body content
Chrome currently allows '#" symbols to exist in the body of a data URI in violation of the URL specification. More specifically, it treats a '#' as both part of the data body and the start of the URL fragment such that there is an overlap between the two components. Chrome now aligns with both the specification and Firefox by treating the first '#' of a data URL as the end of the data body and the start of the fragment.

Removals

Don't allow popups during page unload Pages may no longer use window.open() to open a new page during unload. The Chrome popup blocker already prohibited this, but now it is prohibited whether or not the popup blocker is enabled.

Remove HTTP-Based Public Key Pinning
HTTP-Based Public Key Pinning (HPKP) was intended to allow websites to send an HTTP header that pins one or more of the public keys present in the site's certificate chain. Unfortunately, it has very low adoption, and although it provides security against certificate mis-issuance, it also creates risks of denial of service and hostile pinning. For these reasons, this feature is being removed.

Remove rendering FTP resources.
FTP is a non-securable legacy protocol. When even the linux kernel is migrating off of it, it's time to move on. One step toward deprecation and removal is to deprecate rendering resources from FTP servers and instead download them. Chrome will still generate directory listings, but any non-directory listing will be downloaded rather than rendered in the browser.

Deprecations

Deprecate TLS 1.0 and TLS 1.1
TLS (Transport Layer Security) is the protocol which secures HTTPS. It has a long history stretching back to the nearly twenty-year-old TLS 1.0 and its even older predecessor, SSL. Both TLS 1.0 and 1.1 have a number of weaknesses.
  • TLS 1.0 and 1.1 use MD5 and SHA-1, both weak hashes, in the transcript hash for the Finished message.
  • TLS 1.0 and 1.1 use MD5 and SHA-1 in the server signature. (Note: this is not the signature in the certificate.)
  • TLS 1.0 and 1.1 only support RC4 and CBC ciphers. RC4 is broken and has since been removed. TLS's CBC mode construction is flawed and was vulnerable to attacks.
  • TLS 1.0's CBC ciphers additionally construct their initialization vectors incorrectly.
  • TLS 1.0 is no longer PCI-DSS compliant.

Supporting TLS 1.2 is a prerequisite to avoiding the above problems. The TLS working group has deprecated TLS 1.0 and 1.1. Chrome has now also deprecated these protocols. Removal is expected in Chrome 81 (early 2020).

Deprecate PaymentAddress.languageCode
PaymentAddress.languageCode is the browser's best guess for the language of the text in the shipping, billing, delivery, or pickup address in the Payment Request API. The languageCode is marked at risk in the specification and has already been removed from Firefox and Safari. Usage in Chrome is small enough for safe deprecation and removal. Removal is expected in Chrome 74.

Nee hoor, zoals ik het lees wordt een ftp link nu gewoon gedownload i.p.v. gerenderd in de browser. Tenzij het een directory is...
Eigenlijk is dat wel het gedrag dat ik zou verwachten...
