The openSUSE project developers have announced an increase in hardware requirements in the openSUSE Factory repository and the openSUSE Tumbleweed distribution built on its basis, which uses a continuous cycle of software version updates (rolling updates). Factory packages will be built for the x86-64-v2 architecture, and official support for the x86-64-v1 and i586 architectures will be dropped.
The second version of the x86-64 microarchitecture has been supported by processors since about 2009 (starting with Intel Nehalem) and is distinguished by the presence of extensions such as SSE3, SSE4_2, SSSE3, POPCNT, LAHF-SAHF and CMPXCHG16B. For owners of older x86-64 processors that lack the necessary features, it is planned to create a separate openSUSE:Factory:LegacyX86 repository, which will be maintained by volunteers. As for the 32-bit packages, the full i586 repository will be dropped, but there will be a small part required for wine to work.
