Google Chrome 23

The feature, available for Chrome on Windows, cuts power consumption by executing video decoding on graphics processing units instead of on computers’ CPUs, Google said in a blog post, resulting in a 25 percent increase in battery life in Google tests.

“Now Chrome users on Windows will experience longer battery life so they don’t get cut off while watching their favorite YouTube video on repeat,” wrote Ami Fischman, a Google software engineer.

Security fixes include one that is not in the Chrome browser per se, but rather in the way Apple iOS defends against wild writes in compromised graphics drivers. Google paid $1,000 to the person who reported this bug, rated High, the second-highest rating behind Critical.

Google fixed 13 other security vulnerabilities, including five rated High and seven rated Medium, including one for which it paid a reward of $3,500.

In Chrome 23, users have the option to select Do Not Track, which will include a request with their browser traffic for websites to disable tracking. The move comes after the company announced in February that it would support Do Not Track in Chrome by the end of the year.
