+- 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
