Changes in version 1.2.0                        

  - Added model-based spatially variable gene (SVG) calling.
  - Added spatial visualisation funciton plotSpatial to visualise
    colData, gene expression, and reduced dimensions.
  - Added spatial visualisation function plotCovariate to visualise the
    biolgy, batch, and library size functions estimated by SpaNorm.
  - Dynamic calculation of df.tps for rectangular tissue sections.
  - Allow separate specification of df.tps for biology and library size.
  - Added GLM-PCA approximation through the SpaNormPCA function. The
    null model is considered to consist of the library size effects,
    batch effects, and the gene mean.

                        Changes in version 1.0.0                        

  - Initial Bioconductor submission.
