The last one was great and this one is maybe not as big but brings a whole lot of new goodies to the table!
Here is the info from the G-Stomper webpage:
G-Stomper 4.4 brings a bunch of long awaited features to the G-Stomper apps: Pattern MIDI Export, 4 new 8-Band Vocoders, a new Compressor/Limiter, a Gate and a Transient Shaper Effect, rounded up with new self-contained file formats for Pattern Sets, Patterns and Sound Sets. Furthermore, v.4.4 comes with full Android Marshmallow support and lots of tweaks and bug fixes.
