The CentOS AltArch SIG is a group of people working to build alternative architecture support derived from CentOS Linux's sources. You can find more details about the AltArch group at:
https://wiki.centos.org/SpecialInterestGroup/AltArch
Including details on how to get involved and ways to get help for architecture specific issues.
This is the release announcement for the i386 (Intel 32-bit) Architecture based on the source code released for CentOS-7 (1611). It includes all packages that build on x86 32-bit processors.
The release notes for the normal CentOS-7 apply:
https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7
with the following notes that are specific to i386:

If you already have a previous version of CentOS-7 i386 installed, just running 'yum update' will get you the latest packages installed.

===========================
The CentOS team will have a Dojo in Brussels, Belgium on Friday 3th February 2017:
https://wiki.centos.org/Events/Dojo/Brussels2017
I will be at the Dojo to discuss the i386 distribution with those who are interested. I will also be at the CentOS Booth at FOSDEM 2017 ( https://fosdem.org/2017/ ) in Brussels, Belgium on February 4th and 5th, 2017. I will also attend the Config Management Camp EU ( http://cfgmgmtcamp.eu/ ) in Ghent, Belgium on the 6th of February, 2017. If you have any questions and will be at any of those locations, please look me up.
Bug reports and feedback about specific packages should be filed at https://bugs.centos.org/ against the relevant package name, for project CentOS Linux 7, in the same manner as you would for x86_64. However, do mention the architecture as applicable.
