VentureBeat presents: AI Unleashed - An exclusive executive event for enterprise data leaders. Network and learn with industry peers. Learn More
Chrome is arguably more than a browser: With hundreds of millions of users, it’s a major platform that Web developers have to consider. In fact, with regular additions and changes, developers have to keep up to ensure they are taking advantage of everything available.
An exclusive invite-only evening of insights and networking, designed for senior enterprise executives overseeing data stacks and strategies.
Chrome’s Developer Tools now make visual debugging easier by enabling developers to slow down playback of their animations on the fly, as you can see above. A new section also lets developers view Service Worker caches (just inspect a Service Worker at chrome://serviceworker-internals), meaning you no longer have to manually print out the contents to the console.
Other developer additions include:
- The new CSS value image-rendering: pixelated allows scaled images to appear to be composed of very large pixels, trading smooth results for faster image-scaling.
- CSS Media Queries now support any-pointer and any-hover, which function similarly to pointer and hover but can be triggered by any input device, not only the primary one.
- The Web Audio API now allows developers to temporarily suspend an AudioContext when it’s not in use, improving power consumption. StereoPannerNode is also now supported, enabling left-right panning of an incoming audio stream while maintaining equal power.
- HTTPS sites that have certificate chains using SHA-1 that are valid past January 1, 2017 will be treated as “affirmatively insecure” in Chrome’s interface as part of Google’s plan to gradually sunset SHA-1.
Chrome 41 also includes 51 security fixes, of which Google chose to highlight the following:

If you add all those up, you’ll see Google spent $52,000 in bug bounties for this release. The security improvements alone should be enough for you to upgrade to Chrome 41.
