+- Issue #1813: Fix codec lookup under Turkish locales.
-- Issue #12624: It is now possible to fail after the first failure when
- running in verbose mode (``-v`` or ``-W``), by using the ``--failfast``

- an overzealous DNS service (e.g. OpenDNS) redirects to a placeholder
- Web site.
+- Issue #12551: Provide a get_channel_binding() method on SSL sockets so as
+ to get channel binding data for the current SSL session (only the
+ "tls-unique" channel binding is implemented). This allows the implementation
+ of certain authentication mechanisms such as SCRAM-SHA-1-PLUS. Patch by
+ Jacek Konieczny.
-- Issue #12440: When testing whether some bits in SSLContext.options can be
- reset, check the version of the OpenSSL headers Python was compiled against,

-- Issue #12469: Run "wakeup" signal tests in subprocess to run the test in a
- fresh process with only one thread and to not change signal handling of the
- parent process.
+- Issue #12273: Remove ast.__version__. AST changes can be accounted for by
+ checking sys.version_info or sys._mercurial.
-- Issue #8716: Avoid crashes caused by Aqua Tk on OSX when attempting to run
- test_tk or test_ttk_guionly under a username that is not currently logged
