Document how the pattern recognizer keeps all of its references in bounds.
...
Add a test in case the underlying assumptions ever change (i.e. the
compiler starts generating code blocks that are not punctuated by
RETURN_VALUE).

Teach the peepholer to fold unary operations on constants.
...
Afterwards, -0.5 loads in a single step and no longer requires a runtime
UNARY_NEGATIVE operation.

Transform "x in (1,2,3)" to "x in frozenset([1,2,3])".
...
Inspired by Skip's idea to recognize the throw-away nature of sequences
in this context and to transform their type to one with better performance.

Fix bug that allowed future statements virtually anywhere in a module.
...
If we exit via the break here, we need to set ff_last_lineno or
FUTURE_POSSIBLE() will remain true. The bug affected statements
containing a variety of expressions, but not all expressions. It has
been present since Python 2.2.

Do not fold a constant if a large sequence will result.

Re-running python with/without the -Qnew flag uses incorrectly optimized

bytecodes from the previously saved .pyc files. Fixed by disabling the static
optimization of BINARY_DIVIDE between two constants.

Any call to marshal.dumps() with the new optional argument 'version' just

immediately segfaults, due to a typo! This was obviously never tested...
Added a test for it, and also fixed the documentation.

Hye-Shik Chang's fix for Bug 875692.
...
Improve signal handling, especially when using threads, by forcing an early
re-execution of PyEval_EvalFrame() "periodic" code when things_to_do is not
cleared by Py_MakePendingCalls().
