 - Patch #1479181: split open() and file() from being aliases for each other.
 
+- Patch #1497053: Exceptions occurring in __eq__() methods were always
+  silently ignored by dictionaries when comparing keys.  They are now
+  passed through (except when using the C API function PyDict_GetItem(),
+  whose semantics did not change).
