 +===============================================

 +Release date: 2014-02-10
 +
 +Core and Builtins
 +-----------------
 +
 +- Issue #19255: The builtins module is restored to initial value before
 +  cleaning other modules.  The sys and builtins modules are cleaned last.
 +
 +- Issue #20588: Make Python-ast.c C89 compliant.
 +
 +- Issue #20437: Fixed 22 potential bugs when deleting objects references.
 +
 +- Issue #20500: Displaying an exception at interpreter shutdown no longer
 +  risks triggering an assertion failure in PyObject_Str.
 +
 +- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
 +  input was truncated in BASE64 section.
 +
 +- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
 +  internal codec marking system added for issue #19619 to throw LookupError
 +  for known non-text encodings at stream construction time. The existing
 +  output type checks remain in place to deal with unmarked third party
 +  codecs.
 +
 +- Issue #17162: Add PyType_GetSlot.
 +
 +- Issue #20162: Fix an alignment issue in the siphash24() hash function which
 +  caused a crash on PowerPC 64-bit (ppc64).
 +
 +Library
 +-------
 +
 +- Issue #20530: The signatures for slot builtins have been updated
 +  to reflect the fact that they only accept positional-only arguments.
 +
 +- Issue #20517: Functions in the os module that accept two filenames
 +  now register both filenames in the exception on failure.
 +
 +- Issue #20563: The ipaddress module API is now considered stable.
 +
  - Issue #14983: email.generator now always adds a line end after each MIME
    boundary marker, instead of doing so only when there is an epilogue.  This
    fixes an RFC compliance bug and solves an issue with signed MIME parts.
