What changed from GLM-5.2

Compared with the previous release in this series. A field appears only when both records state a value — where one does not, it is listed as uncomparable rather than dropped, because a gap in our research is not a finding about the model.

Not comparable: Parameters (not researched on both releases); Capabilities and modalities (not researched on both releases)
