- Update to 0.12.0
* All calculations of stacksize now check for stack underflow to
avoid segfault at runtime PR #69
* Fix recursion limitations when compiling bytecode with numerous basic
blocks. PR #57
* Fix handling of line offsets. Issue #67, PR #71
* Forbid an :class:`Instr` to hold an EXTENDED_ARG op_code PR #65
* Forbid the use of :class:`ConcreteInstr` in :class:`Bytecode` and
:class:`ControlFlowGraph` PR #65
This is motivated by the extra complexity that handling possible EXTENDED_ARG
instruction in those representation would bring (stack computation, etc)
* Always remove EXTENDED_ARG when converting :class:`ConcreteBytecode` to
:class:`Bytecode` PR #65
* This is equivalent to say that the :class:`ConcreteBytecode` converted to
:class:`Bytecode` was generated by :meth:`ConcreteBytecode.from_code`
with extended_args=False
* :class:`Instr` now has a new method :meth:`Instr.pre_and_post_stack_effect`
for checking the prerequisite stack size of an operation PR #69
* :meth:`_compute_stack_size` now uses :meth:`Instr.pre_and_post_stack_effect`
to compute the stack size to reject code that will lead to runtime segfault
caused by stack underflow PR #69
