Feature Updates
* Adds contigsreport to current files saved by mothur. 291
* Improves randomization functions
* Sets method driven cutoffs in cluster commands. For methods opti, agc and dgc (cutoff=0.03) which will create OTU for distance 0.03. For methods average, nearest, furthest and weighted (cutoff=0.15) which may be adjusted down due to the sparse matrix, [Why does the cutoff change?](https://mothur.org/wiki/Frequently_asked_questionsWhy_does_the_cutoff_change_when_I_cluster_with_average_neighbor.3F)
Bug Fixes
* Fixes [make.lefse](https://mothur.org/wiki/Make.lefse) output. 314
* Fixes [make.file](https://mothur.org/wiki/Make.file) segfault. 316
* Fixes "couldn't find OTUID" [make.biom](https://mothur.org/wiki/Make.biom) error.
* Fixes Windows subsampling issue. 317
Binaries
* Mac Version requires OSX 10.12 or higher
* Windows 10 or higher
* All linux versions contain the same files with the exception of the mothur executable. The Mothur.linux_64_static.zip contains a statically linked copy of mothur. The Mothur.linux_64.zip contains a dynamically linked copy of mothur. The Mothur.linux_64.noReadLine.zip contains a dynamically linked copy of mothur built without the readline library. The readline library allows you to use the arrow keys to scroll through previous commands within mothur in interactive mode. To use the regular linux version you must have the readline libraries installed. A few of our mothur enthusiasts do not have readline and don’t want to install it so we made a version without that feature.
