                  Changes in version 1.1 (2026-09-09)                   

  - Added data-level gseg1_data() and gseg2_data() interfaces.
  - The data-level interfaces use a k-MST with k = floor(sqrt(N)) by
    default.
  - Default calls report MET. GET, OET, and WET remain available through
    the explicit statistics = "g", "o", or "w" options, or together
    through statistics = "all".
  - Existing graph-level interfaces remain available.
  - Monte Carlo permutation p-values use the standard plus-one
    correction.
  - Corrected changed-interval permutation output so that it retains one
    scan maximum per permutation and uses all B maxima to compute the
    p-value.
  - Added explicit checks for analytic small-sample limits, degenerate
    graphs, duplicate edges, and malformed inputs.
