  • It is now possible to specify more than one amendment (which replaced subprojects).
  • Support for multiple subsample tables

  • Added a sample_modifiers section to house 5 modifiers: remove, append, duplicate, imply, and derive
  • Added a project_modifiers section to house amend and import
  • The structure for 'imply' now uses an if-then format instead of the previous format that was not readily interpretable
