High CVE-2014-7901: Integer overflow in pdfium.

High CVE-2014-7900: Use-after-free in pdfium.

High CVE-2014-7899: Address bar spoofing.

Of these, Google chose to highlight the following:

XMLHttpRequest progress event properties position and totalSize are now deprecated in favor of the loaded and total properties.Ĭhrome 39 also includes 42 fixes (not as many as Chrome 38, but that was primarily a security release).

Scroll offsets (scrollTop, scrollLeft) now return high-precision fractional values in preparation for high-DPI support.

The Beacon API lets developers queue asynchronous network requests that will be sent regardless of whether the user navigates to a new page.

Adding apps to the homescreen is as easy as defining a title, landing page, default orientation, and multiple icons depending on size and screen density.

Web Application Manifests: Starting in Chrome 39, Manifests let developers wrap metadata about a Web application into a single file, reducing duplication and saving a bit of bandwidth.

Web Animation Playback Control: Web Animations, a new API that shipped in Chrome 36 with basic support, now has playback control, including the methods play(), pause(), and reverse(), as well as the ability to jump to a specific point in an animation’s timeline.

The goal is to simplify the process of developing asynchronous code and reduce dependence on callback functions. JavaScript Generators: ES6 Generators allow developers to create iterators that pause their execution after yielding a value, and resume again when later invoked.Here is what Google highlighted in the beta release: OS X aside, Chrome 39 brings a slew of new developer features. Google is hoping to drop 32-bit NPAPI plugin support from Chrome altogether, so this should come as no surprise, in order to “improve Chrome’s security, speed, and stability as well as reduce complexity in the code base.”

The move also means Chrome for Mac no longer supports 32-bit Netscape Plugin Application Programming Interface ( NPAPI) plugins, although their 64-bit counterparts are supported. Now that Chrome’s a 64-bit app too, we expect you’ll find that it launches more quickly and that overall system memory use decreases.

In cases where Chrome was the last remaining 32-bit app, there were launch-time and memory-footprint penalties as 32-bit copies of all of the system libraries needed to be loaded to support Chrome. Another major benefit of this change comes from the fact that most programs on a modern Mac are already 64-bit apps. Improved opportunities for ASLR enhance this version’s security. While Google hasn’t explicitly said so, this would seem that first-generation Intel Macs will not be able to move past Chrome 38.Īs Google has shared before, 64-bit support brings speed and security improvements to its browser:Ħ4-bit Chrome has become faster as a result of having access to a superior instruction set, more registers, and a more efficient function calling convention. All Chrome for Mac users on the stable channel will be updated to the 64-bit version when they get Chrome 39, which doesn’t have a 32-bit equivalent.
