PhyDE 2 is a complete rewrite of the Phylogenetic Data Editor. The first version of PhyDE is in use since 2005 and PhyDE 2 is planned to fully replace it in the future. It does not yet offer all features of the precursor, but some new functionality, like support for additional alignment formats, is already available. For productive use, we currently still recommend to use the old version, but if you want to try out some of the features, feel free to download the latest version of PhyDE 2 from here.
