A 5th beta release is ready to be downloaded with many fixes and improvements. In particular, we have been working on improvements with respect to data products that contain multiple raster sizes, such as the S-2 MSI L1C product. Also a lot of suggestions from our brave beta testers went into this release. Dear users, thanks for all the feedback!
Again, to get this version, it is required to uninstall the previous version of SNAP and request a participation to the Beta test program from the download page: http://step.esa.int/main/download.
