yes, panopress is still under active development, next version will emphasize support for HTML5 panoramas & VR and de-empashize flash, which is basically a legacy technology as far as 360° spherical VR panoramas are concerned
although this wp support area for panopress is not very active, our main forums see quite a bit more activity., please let us know about any desired features or feedback etc there
