Chrome浏览器缩短更新周期至两周 应对AI时代安全威胁

谷歌宣布Chrome浏览器的发布周期正式从四周缩短至两周。1Chrome 153已于本周二在桌面、iOS和Android平台发布，标志着这一重大转变的开始。1谷歌表示，这一改变旨在应对"快速移动的威胁（其中一些也可归因于AI），通过缩小安全补丁从公开代码库到最终用户之间的时间窗口来更好地解决"。1

更频繁的更新周期将有助于减少所谓的"N-day"补丁间隙，即安全漏洞被发现到被修补之间的时间间隔。1Chrome上一次调整发布周期还要追溯到2021年，当时从六周改为四周。1

谷歌的举措已经带动业界跟进。Mozilla、Microsoft和Brave等竞争对手也已开始采用两周发布周期。1

Google has officially shortened Chrome's release cycle from four weeks to two weeks, with Chrome 153 launching this week across desktop, iOS, and Android platforms 1. The accelerated update schedule reflects the browser maker's response to rapidly evolving security threats in the age of artificial intelligence, according to the company.

The compressed release cadence is designed to narrow the window between when security vulnerabilities are discovered in public code repositories and when patches reach end users 1. Google stated that "quickly moving threats, some of which can also be attributed to AI, are better addressed by reducing the time window between security patches from public codebases to end users" 1. This approach reduces what the company refers to as the "N-day" gap—the interval during which a vulnerability remains unpatched after discovery 1. Chrome's previous cycle adjustment occurred in 2021, when Google transitioned from a six-week to a four-week schedule 1.

The move has prompted industry-wide adoption of the faster cadence. Competitors including Mozilla, Microsoft, and Brave have begun following Chrome's lead by adopting their own two-week release cycles 1.
