Today I have released Metaxa2 version 2.1.1, containing a fix to an embarrassing bug in the new metaxa2_uc program (part of the Metaxa2 Diversity Tools). A late change of the names of the different modes of that tool had not propagated to all parts of the code, and therefore only the “model” mode was functional in the previous version. No other changes to the Metaxa2 package has been made in this update, which can be downloaded here.
