 ==========================
 NumPy 1.21.1 Release Notes
 ==========================
+The NumPy 1.21.1 is maintenance release that fixes bugs discovered after the
+1.21.0 release and updates OpenBLAS to v0.3.17 to deal with problems on arm64.
 
+The Python versions supported for this release are 3.7-3.9. The 1.21.x series
+is compatible with development Python 3.10. Python 3.10 will be officially
+supported after it is released.
 
-Highlights
-==========
+.. warning::
+   There are unresolved problems compiling NumPy 1.20.0 with gcc-11.1.
 
+   * Optimization level `-O3` results in many incorrect warnings when
+     running the tests.
+   * On some hardware NumPY will hang in an infinite loop.
