I've spent some time over the new year holidays to bring Lanterna 3.1 into shape, which includes:
* Java 8 source level (with code migrated to Java 8 syntax)
* Java 9 module support
* Improved Menu system
* New Table implementation
* Some minor features that weren't backported to 3.0
I'm intending to do an alpha release to Sonatype soon:ish and update the Github documentation. Also, I think another 3.0 bugfix release is overdue. After this, I don't really have any further plans for the library other than bugfixes.
