Release notes - Sentinel Application Platform - Optical Toolbox 14.0.0

New in Optical Toolbox 14.0

• New FLEX support: added Phase-E1 support for ESA's FLEX mission.
• New hyperspectral tools: added new preprocessing tools, spectral noise reduction and improved spectral-library integration for spectral unmixing.
• Improved PACE OCI support: added reader caching and support for newer OCI L1B products.
• Faster product reading: introduced ReaderCache support for NetCDF and Sentinel-3 readers.
• Modernized optical readers: updated reader implementations, virtual-file-system support and Sentinel-3 DDDB handling.
• Improved Sentinel-2 handling: fixed no-data behavior and resolution handling for the B1 band and masks in L2A products.
• Expanded Sentinel-3 compatibility: added SL_2_WST baseline 004 support and fixed OLCI and DDDB reader issues.
• More reliable optical workflows: restored ENVISAT MERIS Level-1 access and fixed GUI execution of Reflectance to Radiance and Spectral Angle Mapper graphs.
