To provide the best experience for the most-used Linux versions, we will end support for Google Chrome on 32-bit Linux, Ubuntu Precise (12.04), and Debian 7 (wheezy) in early March, 2016. Chrome will continue to function on these platforms but will no longer receive updates and security fixes.
We intend to continue supporting the 32-bit build configurations on Linux to support building Chromium. If you are using Precise, we’d recommend that you to upgrade to Trusty.
The first signs of the end of 32bit are on the wall – starting with Linux. I wonder how long Google will continue to support 32bit Chrome on Windows. For some strange reason, Microsoft is still selling 32bit Windows 10.
