- object now always allocates place for trailing null byte and it's buffer now
- is always null-terminated.
+- Issue #23573: Restored optimization of bytes.rfind() and bytearray.rfind()
+ for single-byte argument on Linux.
-- Issue #24115: Update uses of PyObject_IsTrue(), PyObject_Not(),
- PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains()
- to check for and handle errors correctly.

-- Issue #23985: Fix a possible buffer overrun when deleting a slice from
- the front of a bytearray and then appending some other bytes data.
+- Issue #24619: New approach for tokenizing async/await. As a consequence,
+ is is now possible to have one-line 'async def foo(): await ..' functions.
-- Issue #24102: Fixed exception type checking in standard error handlers.

+- Issue #18622: unittest.mock.mock_open().reset_mock would recurse infinitely.
+ Patch from Nicola Palumbo and Laurent De Buyst.
-- Issue #23309: Avoid a deadlock at shutdown if a daemon thread is aborted
- while it is holding a lock to a buffered I/O object, and the main thread
- tries to use the same I/O object (typically stdout or stderr). A fatal
- error is emitted instead.

+ was a regression vs Python 3.4. Patch from Ignacio Rossi

- Patch by Martin Panter.
+- Issue #24608: chunk.Chunk.read() now always returns bytes, not str.
-- Issue #23803: Fixed str.partition() and str.rpartition() when a separator
- is wider then partitioned string.
+- Issue #18684: Fixed reading out of the buffer in the re module.
-- Issue #23192: Fixed generator lambdas. Patch by Bruno Cauet.
+- Issue #24259: tarfile now raises a ReadError if an archive is truncated
+ inside a data segment.
-- Issue #23629: Fix the default __sizeof__ implementation for variable-sized
- objects.
+- Issue #15014: SMTP.auth() and SMTP.login() now support RFC 4954's optional
