Changes in version 1.1.0.9000                      

                 Changes in version 1.1.0 (2026-06-07)                  

💥 Breaking changes

  - miom$compute_multiregional_multipliers() output columns renamed:
    destination_country, destination_sector, and destination_label are
    now shock_country, shock_sector, and shock_label (they identify the
    origin of the final-demand shock).
  - miom$get_regional_interdependence() now uses block sums from the
    spillover matrix for total_spillover_out and total_spillover_in.
    Removed interdependence_index; added spillover_balance and
    spillover_export_share.

🛠️ Other improvements

  - Update extraction.rsand multipliers.rs in order to lower minimum
    supported Rust version from 1.71 to 1.67.
