[0.3.2] - 2026-06-11

Changed

• optimize(kind='mr') and optimize(kind='mf') no longer broadcast results to the full RF grid.
  Results are now stored as true 1-D outputs:
  • mr_probability_: DataFrame with columns recency, probability
    (previously recency, frequency, probability after broadcast)
  • mf_probability_: DataFrame with columns frequency, probability
    (previously recency, frequency, probability after broadcast)
  • mr_probability_dict_: keyed by recency rank r (int)
    (previously keyed by (r, f) tuple)
  • mf_probability_dict_: keyed by frequency f (int)
    (previously keyed by (r, f) tuple)
• plot_probability_surface() now raises ValueError when kind='mr' or kind='mf' is specified,
  as 1-D models cannot be represented as a surface plot.

Removed

• mr_probability_table_ and mf_probability_table_ attributes.
  These were 2-D broadcast grids produced by the previous implementation and are no longer generated.
