Google says it will end support for Chrome on 32-bit Linux, Ubuntu Precise (12.04) and Debian 7 - to "provide the best experience for the most-used Linux versions".
The company has announced that this change will go into affect in March 2016 and will not alter the 64-bit Linux build.
Google's Dirk Pranke stated that while the 32-bit version of Chrome won't stop working, it will stop receiving security updates and should not be used after the March 2016 cut off. Pranke declared in a statement, “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 upgrade to Trusty.”
For customers that do not have a 64-bit build in place, the Chromium source code will continue to support 32-bit Linux systems and receive updates. Other browsers such as Mozilla Firefox can continue to be used as well.
Mainstream Linux distributions recommend users to adopt the 64-bit releases if possible. Google is spending less time and efforts to support 32-bit and encourages users to update and move on.
