We are now releasing Hydra 1.5. This version has lots of new features (check them), two of the most important ones being the improved image processing pipeline, RAW/OpenEXR/Tone Mapping,  and Aperture integration, import/export/plugin. As a side note: we are aware of some difficulties for image alignment on MacBook and MacMini with Intel Graphics chipsets and we are working on it. Stay tuned and enjoy!
