+==========================
+NumPy 1.18.1 Release Notes
+==========================
+
+This release contains fixes for bugs reported against NumPy 1.18.0.  Two bugs
+in particular that caused widespread problems downstream were:
+
+- The cython random extension test was not using a temporary directory for
+  building, resulting in a permission violation. Fixed.
+
+- Numpy distutils was appending `-std=c99` to all C compiler runs, leading to
+  changed behavior and compile problems downstream. That flag is now only
+  applied when building numpy C code.
+
+The Python versions supported in this release are 3.5-3.8. Downstream
+developers should use Cython >= 0.29.14 for Python 3.8 support and OpenBLAS >=
+3.7 to avoid errors on the Skylake architecture.
