+Subject: [PATCH] Allow running configure with python 3.4.
+
+Details:
+- Relax version blacklisting of python3 to allow 3.4 or later instead
+  of 3.5 or later. Thanks to Dave Love for pointing out that 3.4 was
+  sufficient for the purpose of BLIS's build system. (It should be
+  noted that we're not sure which, if any, python3 versions prior to
+  3.4 are insufficient, and that the only thing stopping us from
+  determining this is the fact that these earlier versions of python3
+  are not readily available for us to test with.)
+- Updated docs/BuildSystem.md to be explicit about current python2 vs
+  python3 version requirements.
