 ====
 
 Rerelease of `mkl-service` package with version bumped to 2.0.0 to avoid version clash with `mkl-service` package from Anaconda.
+
+Improved argument checking, which raises an informative error.
+
+Loading the package with `import mkl` initializes Intel(R) MKL library to use LP64 interface (i.e. use of environment variable `MKL_INTERFACE` will not have effect).
+
+The choice of threading layer can be controlled with environment variable `MKL_THREADING_LAYER`. However the unset variable is interpreted differently that in Intel(R) MKL itself. If `mkl-service` detects that Gnu OpenMP has been loaded in Python space, the threading layer of Intle(R) MKL will be set to Gnu OpenMP, instead of Intel(R) OpenMP.
