We all benefit from an open web that is secure, powerful, and fast. Over
    the past year, we’ve focused our efforts on strengthening the web in three
    areas:
  
  
    - Rethinking how we can deliver a safe and secure web
 
    - Adding the capabilities you need to build powerful, rich, and diverse applications
 
    - Optimizing for performance, for users and developers alike
 
  
  
    This post is a synopsis of the updates we shared during today’s keynote at
    Chrome Dev Summit.
  
  Rethinking privacy from the ground up
  
    We’ve continued work on the
    Privacy Sandbox
    and we are committed to developing an open set of standards that
    fundamentally enhance privacy on the web. Together with the web community,
    we're building new privacy-preserving alternatives to third-party cookies
    or other cross-site tracking mechanisms. With the
    Client Hints API,
    we’re reducing the fingerprinting surface of Chrome, and we have two
    solutions for you to experiment with via our
    Chrome origin trials.
    The Click Conversion Measurement API
    measures ad conversions without using cross-site identifiers, and the
    Trust Token APIs help convey
    trust from one context to another without passive tracking.

    Similarly, the security and privacy of extensions has become of utmost
    importance with hundreds of millions of people using over 250,000 items in
    the Chrome Web Store. We believe extensions must be trustworthy by default
    and it’s why we announced a
    
    draft proposal for a number of changes to our extension platform.
    After incorporating a number of different suggestions from extension
    developers, we're ready to launch the stable release of
    
    Manifest V3 with the goal of increased security, more control and
    privacy for users, and improved performance.
  
  
    With Manifest V3, remote hosted code is no longer permissible to prevent
    malicious extensions that abuse user privacy and security. Additionally,
    the new extensions model allows users to withhold sensitive permissions at
    install time. Lastly, a new approach to background logic with the
    introduction of service workers for background pages and a new declarative
    model for extension APIs provides users more consistent performance
    guarantees. Manifest V3 is now available to experiment with on Chrome
    88 beta, with the Chrome Web Store accepting Manifest V3 extensions
    mid-January when Chrome 88 reaches stable.
  
  Bringing powerful capabilities for advanced apps
  
    Great examples are coming to life from developers who are building new
    experiences on the web. Gravit Designer
    makes it easy for users to read and write files with 
    File System Access APIs and allows the use of specialized fonts
    installed locally with the new Local
    Font Access API. Adobe has made it easy for users to create stunning
    visual stories and beautifully designed content with their
    Spark web app.
  
  
  
    Today, we are adding new capabilities for Progress Web Apps (PWAs) to
    increase their 
    discoverability by being listed in the Google Play Store. In Chrome 86
    we gave you the ability to list your PWA in the Play Store using a
    Trusted Web Activity.
    We’ve now made it possible for you to start accepting payments using the
    new 
    Digital Goods API in Chrome 88.
  
  
    
  
  Optimizing for performance
  
    Chrome’s performance—speed and usage of resources like power, memory, or
    CPU—has always been top of mind so you can deliver the best experience
    for all our users.
  
  
    Earlier this year, we made some key improvements to speed with
    
    Profile Guided Optimization & Tab throttling and today, we announced
    a significant reduction of V8’s memory footprint. Apart from making great
    strides in memory savings through
    V8 pointer compression,
    we’ve eliminated parsing pauses entirely by loading a webpage’s JavaScript
    files in parallel, so scripts can be parsed and compiled and ready to
    execute as soon as they’re needed by the page.
  
  
    Since we announced our Web Vitals initiative,
    they are being increasingly used to measure web page performance. Google
    Search announced
    new signals to search ranking will include 
    Core Web Vitals starting in May 2021. In addition to the
    Chrome User Experience Report,
    Search Console’s Core Web Vitals report,
    and many other Google tools,
    other providers like
    Cloudflare
    are surfacing Core Web Vitals as web page performance metrics.
  
  
    Last summer, we released the
    web-vitals Javascript library
    for those sites using Google Analytics. Today we announced the
    Web Vitals Report, an open
    source website and tool that lets you query and visualize your Web Vitals
    metrics data in Google Analytics, enabling you to easily compare
    performance data across segments.
  
  
  
    Finally, we’ve been listening to your feedback and hearing about your
    difficulties in building web interfaces. We’ve been working to improve
    the web’s styling capabilities and shipped
    content-visibility, a
    CSS feature that significantly improves rendering performance. Look for
    more updates and tools to improve UI styling, including the announcement of
    Houdini.how, a set of APIs that makes it
    easier for you to extend CSS.
  
  A virtual gathering experiment
  
    Chrome Dev Summit has always been about connecting with the community.
    Although we weren’t able to convene together in person, the Chrome team
    launched a PWA to bring the best parts of a physical conference --
    serendipitous conversations, discovering new things, and collecting swag --
    to life with Chrome Dev Summit Adventure.
    We can’t wait to hear what you think of this experiment and look forward
    to chatting with you in real-time.
