Mesquite 3.31 (build 858)
This is release version 3.31 of Mesquite, build 858. For more information see http://mesquiteproject.wikispaces.com. It is a minor update to 3.30, with a few enhancements, but primarily to solve a bug in interaction with alignment programs under older versions of Java.
Note for Mac OS X users: There are two alternative downloads, one labelled as being for OS X 10.9 (Mavericks) and lower, one labelled as being for OS X 10.10 (Yosemite) and higher. The difference is that the 10.9 version uses Java 6 (also known as Java 1.6), and the 10.10+ version uses Java 7 or 8 (also known as Java 1.7 or 1.8). In fact, you can use either Mesquite version for either operating system version (depending on the Java version you have installed), but we recommend them for the operating systems as labelled.
Note for all users: Mesquite 3.31 and older versions will likely not work with Java 1.9.
