There isn’t anything super monumental in this release, but in the 25 closed issues there are lots of little fixes and the seeds for some cool new functionality.

• The new –groups flag for pplacer greatly decreases memory use for placing shotgun reads on very wide alignments
• guppy fpd is a generalized alpha diversity calculator, including phylogenetic entropy and phylogenetic quadratic entropy
• guppy ograph gives the overlap graph for a collection of reads.

As usual, see the CHANGELOG for more details.
