 **conanio/gcc7-centos6-x86** is a special image version based on CentOS 6 i386, GCC 7 and **glibc 2.12** (very old glibc version). This is intended to build executables that run almost on any Linux because **glibc** guarantees backward compatibility. You can use this image to build your Conan build tools packages (`build_requires`). This image is **ONLY** able to build **x86** binaries.
 
+** WARNING ** CentOS 6 reached [EOL](https://wiki.centos.org/About/Product) and won't be longer maintained. Thus, both `conanio/gcc7-centos6` and `conanio/gcc7-centos6-x86` are still available for download, but no new version will be released.
