One of the important differences seems to be more open shapes on such as c, e, 6 and 9. This is a major improvement; I’ve never understood why so many fonts curl around so far as they do, because it definitely harms distinctions. They’ve introduced dotted zero in Neue Frutiger 1450, which I presume means DIN 1450 specifies some such thing. This confuses me, because the ambiguity it introduces with 8 is much worse (for frequency of relevance) than the ambiguity it resolves with O (capital o). Coding monospaces can benefit from dotted or slashed zeroes, and variable-stroke-width serifs can get quite a nice thin slash which makes it clearly neither 8 nor O, but in uniform-stroke-width sans-serifs designed for general-purpose language usage, I’ve just never understood why anyone would do it. It’s obviously worse.
