NCO - Mad Men
This release mainly advances features related to regridding. The primary advance is support for curvilinear regridding. Latitude and longitude may now be two-dimensional coordinates. NCO will now regrid among and between rectangular and curvilinear grids from most (well-behaved) input data files, so regridding swath-like data (SLD) (e.g., WRF and much NASA L2 data) just became a lot easier. The ~/nco/data/sld_nco.sh script integrates the most common regridding tasks into a (hopefully) turnkey solution in time for Thanksgiving.

NCO - Mad Men
Fixes two bugs related to multi-level fields that contain missing values. Symptoms were NC_ERANGE errors when regridding. Reported by PNNL. AFAICT only affected bilinear (non-conservative) remapping.

NCO - Lipstick & Lashes
Disambiguate lat/lon/col_nm into lat/lon/col_nm_in, lat/lon/col_nm_out (so regridded output need not use, e.g., GeoTrack as name). Works well with AIRS L2 + L3 single-level fields.

NCO - I See London
Fix (relatively bad) ncatted bug introduced in 4.5.1 where blank attribute names dump core rather than expanding into all attribute names. Make curvilinear grids with (as yet undocumented) lat_crv, lon_crv, crv options.

NCO - Resilience
With this release NCO can infer SLD grids with --rgr nfr, generate skeleton files with --rgr skl=skl.nc, build without using TeXInfo with --disable-doc, regrid MPAS-O files, accept bounding boxes with --rgr snwe or wesn syntax.

Much more progress on SLD. ncks dies with helpful warning when regridding specified without output file. ncecat resets error code before using it, thus fixing problem where ncecat --gag could fail with single file arguments.

NCO - Parenthood
This NCO release improves regridding features, ncra weighting, and ncatted flexibility, and contains a raft of minor fixes and tunings. Notably, it produces SCRIP-format gridfiles, provides a bugfix to ncra -w, and introduces the --glb option to all operators.

This is the first NCO release that supports regridding datasets, currently limited to global datasets. These features build on infrastructure pioneered by Phil Jones (SCRIP), and the multi-agency Earth System Modeling Framework (ESMF). Other noteworthy improvements include capturing history from appended files, and that ncdismember uploads to the NERC CF-checker upon request.

NCO - Letterman
This release includes small feature improvements in chunking, deflation, and attribute handling during dimension reduction. Also improvements in clarity and consistency of messages. While chunking is an esoteric feature for many, its importance is increasing as the move to netCDF4 (classic) continues. The chunking defaults and flexibility have reached a new level of robustness in this release. Benchmarks suggest this chunking can accelerate wallclock performance of netCDF4 workflows by 50% relative to 4.4.8.
The main new awesome feature is that ncra understands weights. Finally. Applying uneven weights to different input files was too clunky. This release is dedicated to the intrepid souls who use NCO to generate climatologies that require uneven weights. This release should make that task much easier.
