New version of GIB seems to like to bid 2nt a lot in response to 3rd/4th hand 1M. Instead of 1nt "semi-forcing". I think this is a mistake given that one might want to open a bit light in those positions and pass 1nt. It's probably OK to define 2nt the way it is (in case a human bids it), but it should prioritize bidding 1nt IMO planning on a 2nt rebid if given the opportunity. No reason to play 2nt if opener wants to pass 1nt.

Gib also would almost never make a passed hand natural 2/1 which at least is more useful thana PH 2N.
Now Gib plays Drury so 2/1 happens less often. Supposedly Gib will now bid 2H more often but haven't seem yet.

Increased frequency of 2H I like. Drury I like. 2nt I don't.

maybe they will add XYZ

I haven't seen this happen but I will keep an eye out. In general, GIB will not be catering to light openings in third seat, although of course that doesn't mean it should be responding 2NT either.

A natural passed-hand 2NT response to a major takes up too much room unnecessarily. Opener's rebid of 3 of a lower suit is NF, leaving you stuck with a shapely game-going hand that wants to explore options other than, but also including, 3NT.
