The programmatic drawing engine has been reengineered to support many new features, such as circular visualization, new face positions, extra face properties, full SVG support and more!

ETE 2.1 includes a webplugin module to generate interactive WEB tree images.
ETE 2.1 adds support for both NexML and PhyloXML formats. These two standards are now natively supported by ETE, allowing trees encoded under NeXML and PhyloXML languages to be automatically converted to ETE phylogenetic tree objects.
A new PhylomeDB v3 API is now included. PhylomeDB v3 includes many improvements, such as the adoption of a unique ID system for sequences across datasets and the iclusion of new phylomes. Salvador Capella has developed an update of the PhylomeDBConnector API object that allows to access to phylomeDB mysql servers directly.
Backward compatible with old ETE 2.0 scripts
ETE is developed as an academic free software tool. If you find ETE useful for your work, please cite:

The ETE Toolkit was originally
developed at the bioinformatics
department of CIPF and greatly improved
at the comparative genomics unit
of CRG. At present, ETE is maintained by Jaime
Huerta-Cepas at the Structural and
Computational Biology unit of EMBL (Heidelberg,
Germany).
