+* A new built-in, ``next(*iterator*, [*default*])`` returns the next item
+ from the specified iterator. If the *default* argument is supplied,
+ it will be returned if *iterator* has been exhausted; otherwise,
+ the :exc:`StopIteration` exception will be raised. (:issue:`2719`)
+
* Tuples now have an :meth:`index` method matching the list type's
:meth:`index` method::
:mod:`terminalcommand`.
A number of old IRIX-specific modules were deprecated:
+ :mod:`al` and :mod:`AL`,
:mod:`cd`,
:mod:`cddb`,
:mod:`cdplayer`,
to drop the built-in in the 2.x series. (Patched by
Christian Heimes; :issue:`1739906`.)
+* When possible, the :mod:`getpass` module will now use
+ :file:`/dev/tty` (when available) to print
+ a prompting message and read the password, falling back to using
+ standard error and standard input. If the password may be echoed to
+ the terminal, a warning is printed before the prompt is displayed.

+
* The :func:`glob.glob` function can now return Unicode filenames if
a Unicode path was used and Unicode filenames are matched within the
directory. (:issue:`1001604`)
This is more efficient than making a call to :func:`heappush` and then
:func:`heappop`.
+ :mod:`heapq` is now implemented to only use less-than comparison,
+ instead of the less-than-or-equal comparison it previously used.
+ This makes :mod:`heapq`'s usage of a type match that of the
+ :meth:`list.sort` method.

* An optional ``timeout`` parameter was added to the
is true, opening of the log file is deferred until the first
:meth:`emit` call is made. (Contributed by Vinay Sajip.)
+ :class:`TimedRotatingFileHandler` also has a *utc* constructor
+ parameter. If the argument is true, UTC time will be used
+ in determining when midnight occurs and in generating filenames;
+ otherwise local time will be used.
+
* The :mod:`macfs` module has been removed. This in turn required the
:func:`macostools.touched` function to be removed because it depended on the
:mod:`macfs` module. (:issue:`1490190`)

Information about the command-line arguments supplied to the Python
- interpreter are available as attributes of a ``sys.flags`` named
- tuple. For example, the :attr:`verbose` attribute is true if Python
+ interpreter is available by reading attributes of a named
+ tuple available as ``sys.flags``. For example, the :attr:`verbose`
+ attribute is true if Python
was executed in verbose mode, :attr:`debug` is true in debugging mode, etc.
These attributes are all read-only.

+ A new function, :func:`getsizeof`, takes a Python object and returns
+ the amount of memory used by the object, measured in bytes. Built-in
+ objects return correct results; third-party extensions may not,
+ but can define a :meth:`__sizeof__` method to return the
+ object's size.
+ (Contributed by Robert Schuppenies; :issue:`2898`.)
+
It's now possible to determine the current profiler and tracer functions
by calling :func:`sys.getprofile` and :func:`sys.gettrace`.
(Contributed by Georg Brandl; :issue:`1648`.)
(Contributed by Dwayne Bailey; :issue:`1581073`.)
+* The :mod:`threading` module's :class:`Thread` objects
+ gained a :meth:`getIdent` method that returns the thread's
+ identifier, a nonzero integer. (Contributed by XXX; :issue:`2871`.)
+
* The :mod:`timeit` module now accepts callables as well as strings
for the statement being timed and for the setup code.
Two convenience functions were added for creating
the corresponding method. (Contributed by Erik Demaine;
:issue:`1533909`.)
+* The :mod:`turtle` module for turtle graphics was greatly enhanced by
+ Gregor Lingl. New features in the module include:
+
+ * Better animation of turtle movement and rotation.
+ * Control over turtle movement using the new delay(),
+ tracer(), and speed() methods.
+ * The ability to set new shapes for the turtle, and to
+ define a new coordinate system.
+ * Turtles now have an undo() method that can roll back actions.
+ * Simple support for reacting to input events such as mouse and keyboard
+ activity, making it possible to write simple games.
+ * A :file:`turtle.cfg` file can be used to customize the starting appearance
+ of the turtle's screen.
+ * The module's docstrings can be replaced by new docstrings that have been
+ translated into another language.
+
+ (:issue:`1513695`)
+
* An optional ``timeout`` parameter was added to the
:func:`urllib.urlopen` function and the
:class:`urllib.ftpwrapper` class constructor, as well as the
not necessarily correct for all applications. Code using
:mod:`xmlrpclib` should convert :class:`date` and :class:`time`
instances. (:issue:`1330538`) The code can also handle
- dates before 1900. (Contributed by Ralf Schmitt; :issue:`2014`.)
-
+ dates before 1900 (contributed by Ralf Schmitt; :issue:`2014`)
+ and 64-bit integers represented by using ``<i8>`` in XML-RPC responses
+ (contributed by XXX; :issue:`2985`).
+
* The :mod:`zipfile` module's :class:`ZipFile` class now has
:meth:`extract` and :meth:`extractall` methods that will unpack
a single file or all the files in the archive to the current directory, or
(Contributed by Alan McIntyre; :issue:`467924`.)
- Also, :mod:`zipfile` now supports using Unicode filenames
- for archived files. (Contributed by Alexey Borzenkov; :issue:`1734346`.)
+ The :meth:`open`, :meth:`read` and :meth:`extract` methods can now
+ take either a filename or a :class:`ZipInfo` object. This is useful when an
+ archive accidentally contains a duplicated filename.
+ (Contributed by Graham Horler; :issue:`1775025`.)
+ Finally, :mod:`zipfile` now supports using Unicode filenames
+ for archived files. (Contributed by Alexey Borzenkov; :issue:`1734346`.)
