 interfacing with C.

+We now use shadowstack as our default gcrootfinder_ even on Linux. The
+alternative, asmgcc, will be deprecated at some future point. While about 3%
+slower, shadowstack is much more easily maintained and debuggable. Also,
+the performance of shadowstack has been improved in general: this should
+close the speed gap between Linux and other platforms.
 
 As always, this release fixed many issues and bugs raised by the
 growing community of PyPy users. We strongly recommend updating.
