Google has said today that Chrome will no longer be supported on several legacy operating systems.
While Microsoft stopped supporting XP in April of last year, Google announced that they would continue providing updates and security patches to Chrome till the end of 2015:
Millions of people are still working on XP computers every day. We want those people to have the option to use a browser that’s up-to-date and as safe as possible on an unsupported operating system.
In a post today on the Chrome blog, Google announced when they will finally stop supporting XP: April 2016. Additionally, Windows Vista will stop getting support as well. On the Mac side, Google is dropping support for Mac OS X 10.6, 10.7, and 10.8 around the same time.
Google notes that the operating systems are no longer being actively supported by Microsoft and Apple, and they encourage users to move to a newer OS in order to receive the latest Chrome versions and features.
