Version 1.1¶
Released 2nd May 2019.
Initial support of region of interest and the HDF5-IDIA image format.
This version enables the initial support of region of interest and relevant analysis tools (statistics, histogram, region spectral profiler). Initial support of the HDF5-IDIA image format is implemented, which takes the advantage of pre-calculated data and rotated cube to speed up some time-consuming tasks. A basic server-side authentication model and command line startup options are provided. Performance enhancement and bug fixes are included as well.

Version 1.0¶
Released 29th December 2018.
Initial release.
This version provides basic image viewing capabilities, basic profile viewing capabilities in both spatial and spectral domains, and basic per-frame or per-cube histogram viewing capabilities. Exporting images or charts in png format and charts in plain text format are supported.
