### v1.1.alpha12: new code and general improvements

14 Mar 2012, by Erick

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.
