Changes in version 2.0.0                        

  - Added support for directed cell-cell interaction (see
    calculate_gene_scores_directed, calculate_influence)
  - Functions for supporting ligand-receptor interactions based on
    directed cell-cell interactions
  - Added ligand–receptor and gene-set scoring utilities:
    calculate_lr_scores, calculate_gene_set_score, and
    calculate_gene_set_specificity.
  - Added support for handling Visium HD
  - plotting functions using circlize for showing ligand-receiver
    interactions.
  - API and naming standardization (backwards-incompatible) Major public
    functions renamed to snake_case for consistency (examples:
    calcInfluence → calculate_influence, getInteractingGenes →
    get_interacting_genes, getPairwiseInteractingGenes →
    get_pairwise_interacting_genes, getSpatialFeatures →
    get_spatial_features, getSpatialParameters → get_spatial_parameters)

                        Changes in version 1.5.0                        

  - Added findAllHotspots to use with getPairwiseInteractingGenes
  - Return empty interacting genes list instead of failing with error
    when no genes pass fdr threshold.

                        Changes in version 1.2.0                        

  - Updated SpaceMarkersMetric by fixing signage and log transformed to
    scale magnitude
  - Added get_spatial_paramsExternal which enables getting spatial
    parameters from file or from the user.
  - Deprecated getSpatialParameters
  - Enabled includeSelf = TRUE in getInteractingGenes.R to improve
    hotspot detection
  - Enabled load10XCoords to read coordinates from VisiumHD directory
  - Optimized the long running row.dunn.test() function
  - Corrected sparse -> dense conversions
  - Added getPairwiseInteractingGenes which enables pairwise analysis of
    interacting patterns
  - getSpatialFeatures: add default method to infer the object passed to
    it.

                        Changes in version 0.1.0                        

  - Added a NEWS.md file to track changes to the package.
