There is now an Arb equivalent of the Sage ticket that implements the generalised Bernoulli function but nothing else: https://github.com/fredrik-johansson/arb/pull/438 Any further equivalents (e.g. on mpmath) will be edited into the description of the Sage ticket rather than being mailed

has to be special-cased out of formulae where B_1 is normally used. That B_n for odd n at least 3 is zero may provide computational advantages, but is a non-trivial fact. It is more parsimonious to put the even, one and greater-odd instances of the Bernoulli numbers into one bag. Jeremy Tan / Par

mbers with B_1 = +½, and given SageMath with B_1 = +½, would have a lot more fun than if B_1 = -½ was initially given instead. Finally I would like to drop a quip from the manifesto: "My impression is that the number of modern authors who use B_1 = +½ is steadily increasing." Jeremy
