Shira Universe 3.4 version includes many updates, bug fixes and new features listed below.

* New High resolution Milkyway texture produced by Gaia Project.

Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. (source : http://sci.esa.int/gaia/ )
