New features:

• Add support for NumPy percentile methods: midpoint, inverted_cdf, averaged_inverted_cdf, closest_observation, interpolated_inverted_cdf, hazen, weibull, median_unbiased, normal_unbiased
• Add predefined healpix grid hp<nside>[_<order>]
• Add healpix grid support to Zonstat module (zonmean, ...)
• Add compression support for NetCDF4 remap weights file (-f nc4 -z <...>)
• Add support for NetCDF4/HDF5 compression method Zstandard (cdo option -z zstd)
• Add support for NetCDF4/HDF filter (cdo option --filter <filterId,params>)
• Improved read performance of spatial and temporal chunked NetCDF4 data

New operators:

• hpdegrade: Degrade the resolution of a healpix grid
• hpupgrade: Upgrade the resolution of a healpix grid
• splitdate: Splits a file into dates
• fldcount: Number of non-missing values of the field
• unpack: Unpack packed data

Changed operators:

• sethalo: extend user interface (new parameter east/west/south/north and value)

Fixed bugs:

• select: Error prone evaluation of timestepmask
• timpctl: returns missing values when input data is constant in time
• ml2hl: Change level type to ZAXIS_ALTITUDE
• sp2sp: Specification of the parameter fails
• Option -t failed in release 2.1.1
• Yseasstat: vDateTimes not initialized
• intlevel3d: use level indices from target coordinate [Bug #11307]
• Vertstat: wrong result for non monotonic levels in GRIB format [Bug #11323]
