cds-crtools was updated to version 4.11 in the CDS conda environment.
The major changes are:
FOTON_WARN_RHP_ZEROS=true.

that are ostensibly on the imaginary axis, but due to precision issues are slightly in the right-hand plane will no longer be flagged.A complete change history for all crtools can be found here:
