Hi all,

I just released Cython 0.29.4 with an important bug fix(*) for division
operations that involve constant numerators. If the denominator turns out
to be zero at runtime, it could happen that no ZeroDivisionError gets
raised, and instead an arbitrary result returned.


Upgrading is recommended to restore correctness.


(*) You could argue that support for division by zero is a rather
oustanding feature, but … I think the surprise factor outweighs the
coolness here.
