Column evolution matrix
Hover a cell for the column type9.0 is the coverage baseline; a column already present in the baseline is not marked as added. The matrix aligns columns by name, so a rename appears as the old column removed and a new column added.
Evolution timeline
Changes between adjacent majorsNo column-structure or description change between the covered versions.
