Runtime/Behavior Changes

The enum used for Article view hooks (cm.core.calc) have a new enum value modified, which is used to notify modifications to the article view

/**
 * View change type.
 */
public enum articleViewChange : field access {
    nothing;
    name;
    modified; //New in 12.5
    new;
    remove;
    select;
}

articleViewChange.remove notification now correctly populates the view argument with the deleted ArticleView instance, instead of passing in null.
