Changes in version 0.1.0 (2026-09-18)                  

  - Initial standalone package for matrix partial EM (MPEM).
  - Added one public mpem() interface for incomplete
    Kronecker-structured matrix-normal data.
  - Added automatic dispatch between general MPEM for arbitrary
    missingness and Rect-MPEM for rectangular structural missingness.
  - Returned imputed data and fitted parameters directly in the mpem_fit
    object.
  - Added finite mixtures of matrix-normal distributions directly to
    mpem() through G > 1, with weighted general MPEM and weighted
    Rect-MPEM updates.
