Hail fellow netCDFers!

In version netcdf-4.9.0 (way back in the innocent days of 2022), new
compression features were introduced: quantization and zstandard
compression.

Quantization allows users to set the number of significant bits to be
retained for floating point numbers. Excess bits are compressed. Zstandard
compression is like zlib, but faster.

I would be very interested to hear from users who are using these features.
Are they working well? I would be interested in both good and bad
experiences with these new features.

Thanks, and keep on netCDFing!
