These are detailed in the Version History file in the download package. The diversity index is also regressed against node age. This will affect the reported slopes but not the P-values. One word clade names are now acceptable. Clades can be omitted from analysis by entering the clade richness as zero.
Minor bug fixes .
Other cosmetic changes are outlined in the Version History file. It also contained several bug fixes of previous versions. These are questions that can be studied with comparative analysis, an examination of a group of organisms' evolutionary history and their essential characters to obtain correlations between these characters. MacroCAIC performs a specialised subset of this analysis, looking at correlates of species richness. MacroCAIC can calculate correlates of species richness, i.e. which traits are associated with abnormal speciation.
