Chrome browser update frequency
Google announced in March that starting from Chrome 94 in the third quarter of 2021, the frequency of milestone updates will be changed from six weeks to four weeks. The company will also release minor security updates every two weeks. According to Google, it will increase the update frequency of ChromeOS, starting from ChromeOS 96 version to synchronize with the Chrome browser. The company will also offer a six-month update channel for Chromebooks in corporate and educational environments. ChromeOS 94 will be official on September 21. In order to keep up with the version number of the Chrome browser, ChromeOS will skip version 95.
From the fourth quarter of 2021, Google will speed up the update frequency of Chrome OS. This change will probably begin in October when the official version of ChromeOS 96 will launch. In the official Google Chromium blog, the head of ChromeOS, Marina Kazatcke, said that the purpose of this change is to enable consumers to experience new features as soon as possible. The company wants to also ensure that ChromeOS maintains security, stability, and simplicity.
Of course, Google will port directly to the ChromeOS 96 from the ChromeOS 94 version. This means that there will be no ChromeOS 95 version. In addition to the fast track for monthly updates, Google also allows companies and schools to set up a six-month update mode to reduce maintenance costs.
