Significant changes in Chrome 40:
- Disabled SSLv3 support by default.
- The minimum SSL/TLS version can now be set through about:flags.
- Updated info dialog for Chrome app on Windows and Linux.
- A new clock behind/ahead error message.
Significant changes in Android version of Chrome 40:
- Updated page info and content settings UI.
- Number of bug fixes and performance improvements.
Significant changes in iOS version of Chrome 40:
- New look with Material Design bringing bold graphics, fluid motion, and tactile surfaces.
- iOS 8 optimizations and support for bigger phones.
- Support handoff from Chrome to your default browser on OS X.
- Stability improvements and bug fixes.
Chrome 40 adds the following new features:
- Content Security Policy Level 2 - An evolution of the Content Security Policy specification, allowing developers to create a whitelist of sources of trusted content, and instructing the browser to only execute or render resources from those sources.
- Service ServiceWorkers - Formerly Navigation Controllers are a new system that provides event-driven scripts that run independent of web pages. They are similar to SharedWorkers except that their lifetime is different and they have access to domain-wide events such as network fetches. Use cases: offline, reducing perceived page load latency and will eventually power notification/push/sync use cases.
- Changed WebAudio PannerNode default behavior - The HRTF panner uses significant memory for the responses and requires a fair amount of processing to implement. For low-end mobile devices, this can be an issue. Since the default panner model is HRTF, the creation of the panner can cause the responses to be loaded. The default has been changed to equalpower, which doesn't consume significant memory and is much less intensive in processing power.
- minlength attribute - minlength attribute declares a lower bound on the number of characters a user can input.
- reportValidity() for form controls - reportValidity() invokes built-in form validation UI programatically.
The new release fixes 62 security issues. In no particular order some of the most critical security fixes include:
