R now uses openblas instead of the unoptimized blas bundled with R (on all architectures where openblas is supported). In the previous update, this was done by symlinking /usr/lib64/R/lib/libRblas.so to /usr/lib64/libopenblas.so.0. While this worked fine for R, it did not work for anything linking to libR.so or trying to dynload libRblas.so.
To resolve this, a new openblas subpackage (openblas-Rblas) has been added, which contains a copy of openblas built as libRblas.so (and reporting libRblas.so as its soname). R now depends on openblas-Rblas on all architectures which support openblas and on all targets new enough to build openblas (RHEL 7+, Fedora 23+). Older targets or incompatible architectures use the unoptimized Rblas.
