+- update to 3.3.9:
+  * New API fftw_planner_nthreads() returns the number of threads
+    currently being used by the planner.
+  * Fix incorrect math in 128-bit generic SIMD
+  * Fix wisdom for avx512.
+    The avx512 alignment requirement was set to 64 bytes, but this is
+    wrong.  Alignment requirements are a property of the platform (e.g.,
+    x86) and not of the instruction set (e.g., AVX).  Among other
+    things, this broke wisdom with avx512.
+    Note that avx512 support is still experimental because the FFTW
+    authors have no avx512 hardware available for testing.
+  * fftw_threads_set_callback function to change the threading backend at runtime.
