+  * update copyright year
+
+- update to version 17.4.0:
+  * Backward-incompatible Changes
+    + The traversal of MROs when using multiple inheritance was
+      backward:
+      If you defined a class "C" that subclasses "A" and "B" like
+      "C(A, B)", "attrs" would have collected the attributes from "B"
+      *before* those of "A".
+      This is now fixed and means that in classes that employ multiple
+      inheritance, the output of "__repr__" and the order of
+      positional arguments in "__init__" changes.
+      Due to the nature of this bug, a proper deprecation cycle was
+      unfortunately impossible.
+      Generally speaking, it's advisable to prefer "kwargs"-based
+      initialization anyways – *especially* if you employ multiple
+      inheritance and diamond-shaped hierarchies.
+    + The "__repr__" set by "attrs" no longer produces an
+      "AttributeError" when the instance is missing some of the
+      specified attributes (either through deleting or after using
+      "init=False" on some attributes).
+      This can break code that relied on "repr(attr_cls_instance)"
+      raising "AttributeError" to check if any attr-specified members
+      were unset.
+      If you were using this, you can implement a custom method for
+      checking this::
+
+      def has_unset_members(self):
+          for field in attr.fields(type(self)):
+              try:
+                  getattr(self, field.name)
+              except AttributeError:
+                  return True
+          return False
+  * Deprecations
+    + The "attr.ib(convert=callable)" option is now deprecated in
+      favor of "attr.ib(converter=callable)".
+      This is done to achieve consistency with other noun-based
+      arguments like *validator*.  *convert* will keep working until
+      at least January 2019 while raising a "DeprecationWarning".
+
+  * Changes
+    + Generated "__hash__" methods now hash the class type along with
+      the attribute values.  Until now the hashes of two classes with
+      the same values were identical which was a bug.
+      The generated method is also *much* faster now.
+    + "attr.ib"’s "metadata" argument now defaults to a unique empty
+      "dict" instance instead of sharing a common empty "dict" for
+      all.  The singleton empty "dict" is still enforced.
+    + "ctypes" is optional now however if it's missing, a bare
+      "super()" will not work in slots classes.  This should only
+      happen in special environments like Google App Engine.
+    + The attribute redefinition feature introduced in 17.3.0 now
+      takes into account if an attribute is redefined via multiple
+      inheritance.  In that case, the definition that is closer to the
+      base of the class hierarchy wins.
+    + Subclasses of "auto_attribs=True" can be empty now.
+    + Equality tests are *much* faster now.
+    + All generated methods now have correct "__module__", "__name__",
+      and (on Python 3) "__qualname__" attributes.
