+- update to version 0.4.6:
+  * Expose `_stack_saved` property on greenlet objects, it may be
+    used to introspect the amount of memory used by a saved stack,
+    but the API is subject to change in the future
+  * Added a workaround for `return 0` compiler optimizations on all
+    architectures
+  * C API typo fixes
+- add -fno-strict-aliasing to CFLAGS to fix compiler warnings
+- remove hidden file .buildinfo from html documentation
+
