• [ECC-1520] - grib_filter/bufr_filter: Provide way of reading environment variables
• [ECC-1521] - Drop support for 32-bit architectures
• [ECC-1543] - GRIB2: New parameter encodings for DestinationEarth
• [ECC-1544] - GRIB2: Deprecation of parameter definitions
• [ECC-1545] - GRIB2: Deletion of parameter definitions
• [ECC-1549] - GRIB2: New parameter encodings for upcoming tile templates
• [ECC-1556] - Add new MARS class ML for machine learning
• [ECC-1557] - Add new MARS class D1 for Destination Earth
