  -----------------
  
+ - Issue #12911: Fix memory consumption when calculating the repr() of huge
+   tuples or lists.
+ 
 +- PEP 393: flexible string representation. Thanks to Torsten Becker for the
 +  initial implementation, and Victor Stinner for various bug fixes.
 +
 +- Issue #13012: The 'keepends' parameter to str.splitlines may now be passed
 +  as a keyword argument:  "my_string.splitlines(keepends=True)".  The same
 +  change also applies to bytes.splitlines and bytearray.splitlines.
 +
  - Issue #7732: Don't open a directory as a file anymore while importing a
    module. Ignore the direcotry if its name matchs the module name (e.g.
    "__init__.py") and raise a ImportError instead.
