- Issue #15801: Make sure mappings passed to '%' formatting are actually
subscriptable.
-- Issue #15726: Fix incorrect bounds checking in PyState_FindModule.
- Patch by Robin Schreiber.
+Library
+-------
-- Issue #15604: Update uses of PyObject_IsTrue() to check for and handle
- errors correctly. Patch by Serhiy Storchaka.
+- Issue #15970: xml.etree.ElementTree now serializes correctly the empty HTML
+ elements 'meta' and 'param'.
-- Issue #13119: sys.stdout and sys.stderr are now using "\r\n" newline on
- Windows, as Python 2.
+- Issue #15842: the SocketIO.{readable,writable,seekable} methods now
+ raise ValueError when the file-like object is closed. Patch by Alessandro
+ Moura.
-- Issue #14579: Fix CVE-2012-2135: vulnerability in the utf-16 decoder after
- error handling. Patch by Serhiy Storchaka.
+- Issue #15882: Change _decimal to accept any coefficient tuple when
+ constructing infinities. This is done for backwards compatibility
+ with decimal.py: Infinity coefficients are undefined in _decimal
+ (in accordance with the specification).
-- Issue #15404: Refleak in PyMethodObject repr.
+- Issue #15876: Fix a refleak in the curses module: window.encoding.
-- Issue #15394: An issue in PyModule_Create that caused references to
- be leaked on some error paths has been fixed. Patch by Julia Lawall.
+- Issue #15881: Fixed atexit hook in multiprocessing. Original patch
+ by Chris McDonough.
-- Issue #15368: An issue that caused bytecode generation to be
- non-deterministic when using randomized hashing (-R) has been fixed.
+- Issue #15340: Fix importing the random module when /dev/urandom cannot
+ be opened. This was a regression caused by the hash randomization patch.
-- Issue #15020: The program name used to search for Python's path is now
- "python3" under Unix, not "python".
+- Issue #15841: The readable(), writable() and seekable() methods of BytesIO
+ and StringIO objects now raise ValueError when the object has been closed.
+ Patch by Alessandro Moura.
-- Issue #15033: Fix the exit status bug when modules invoked using -m swith,
- return the proper failure return value (1). Patch contributed by Jeff Knupp.
+- Issue #15447: Use subprocess.DEVNULL in webbrowser, instead of opening
+ os.devnull explicitly and leaving it open.
-- Issue #12268: File readline, readlines and read() or readall() methods
- no longer lose data when an underlying read system call is interrupted.
- IOError is no longer raised due to a read system call returning EINTR
- from within these methods.
+- Issue #15509: webbrowser.UnixBrowser no longer passes empty arguments to
+ Popen when %action substitutions produce empty strings.
-- Issue #15142: Fix reference leak when deallocating instances of types
- created using PyType_FromSpec().
+- Issue #12776,#11839: call argparse type function (specified by add_argument)
+ only once. Before, the type function was called twice in the case where the
+ default was specified and the argument was given as well. This was
+ especially problematic for the FileType type, as a default file would always
+ be opened, even if a file argument was specified on the command line.
-- Issue #10053: Don't close FDs when FileIO.__init__ fails. Loosely based on
- the work by Hirokazu Yamamoto.
+- Issue #15906: Fix a regression in argparse caused by the preceding change,
+ when action='append', type='str' and default=[].
-- Issue #14775: Fix a potential quadratic dict build-up due to the garbage
- collector repeatedly trying to untrack dicts.

+ _set_npn_protocols() is called multiple times, thanks to Daniel Sommermann.

+ to Anton Barkovsky.
