+  Go 1.15 is the last release to support x87-only floating-point
+  hardware (<code>GO386=387</code>). Future releases will require at
+  least SSE2 support on 386, raising Go's
+  minimum <code>GOARCH=386</code> requirement to the Intel Pentium 4
+  (released in 2000) or AMD Opteron/Athlon 64 (released in 2003).
