new synthesis tree; other features

[Karen Cranston]

We have just released a new version of the synthetic tree as well as some new website features:

I. Synthetic tree v6.1: includes 155 new input trees and >4100 new phylogeny tips; browse at https://tree.opentreeoflife.org  ; release notes at https://tree.opentreeoflife.org/about/synthesis-release/v6.1 

II. Support and conflict: for each node in the synthetic tree, we now show input trees that corroborate the shown relationships as well as those that conflict. See, for example, https://tree.opentreeoflife.org/opentree/opentree6.1@mrcaott2ott8384/Vitales--rosids 

III. Adding new taxa to the taxonomy: Now, when curating trees, you can add unmapped labels to the Open Tree Taxonomy. See https://github.com/OpenTreeOfLife/opentree/wiki/Adding-tips-from-trees-to-the-taxonomy for documentation.

As always, feedback on the tree or new features always welcome!
