Some smaller changes made to the core Python language are:
-* Stub
+* The :func:`hasattr` function used to catch and suppress any Exception.
+ Now, it only catches :exc:`AttributeError`. Under the hood, :func:`hasattr`
+ works by calling :func:`getattr` and throwing away the results. This is
+ necessary because dynamic attribute creation is possible using
+ :meth:`__getattribute__` or :meth:`__getattr`. If :func:`hasattr` were to
+ just scan instance and class dictionaries it would miss the dynmaic methods
+ and make it difficult to implement proxy objects.
+
+ (Discovered by Yury Selivanov and fixed by Benjamin Peterson; :issue:`9666`.)
+
+* The :func:`str` of a float or complex number is now the same as it
+ :func:`repr`. Previously, the :func:`str` form was shorter but that just
+ caused confusion and is no longer needed now that we the shortest possible
+ :func:`repr` is displayed by default.
+
+ (Proposed and implemented by Mark Dickinson; :issue:`9337`).

Changes to Python's build process and to the C API include:
-* Stub
+* The C functions that access the Unicode Database now accept and
+ return characters from the full Unicode range, even on narrow unicode builds
+ (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
+ in Python is that :cfunc:`unicodedata.numeric` now returns the correct value for
+ large code points, and :func:`repr` may consider more characters as printable.
+
+ (Reported by Bupjoe Lee and fixed by Amaury Forgeot D'Arc; :issue:`5127`.)
+
+* Computed gotos are now enabled by default on supported
+ compilers (which are detected by the configure script). They can still
+ be disable selectively by specifying ``--without-computed-gotos``.
