Aug 1, 2025In August 2025, the PypeIt project delivered a targeted documentation correction in the coadd3d module to fix a misnamed sensitivity parameter, aligning docs with the actual configuration (sensfile) and reducing user confusion. The change required no code alterations beyond documentation and is captured in a dedicated commit for traceability. This work improves onboarding, support efficiency, and overall user trust in the toolchain.
