<p class="MsoNormal">For the upcoming 4.2 release (scheduled for ~mid February) we migrate to Java 1.7. After the 4.2 release becomes available, the master branch on GitHub (i.e. the developmental code base) gets scheduled for the next major 5.0 release and
starts using Java 1.8. <o:p></o:p></p>

<p class="MsoNormal">That way the future 5.0 release will be the first stable release using Java 1.8. However all the active developers who want to start using the latest Java features will be able to do so in about a month by using the latest code from git.<o:p></o:p></p>

<br>
I'm the lead developer for the Tassel software, and we use the Biojava<br>
libraries. We've required Java 8 for Tassel since August 2014. If<br>
you change, some users will need to upgrade Java regardless. I<br>
recommend going to Java 8.<br>
