Changelog

Sourced from grib's changelog.

[0.18.3] - 2026-09-06

New supports

• Computation of grid point latitudes and longitudes:
  • Template 3.10 (Mercator) (Both a built-in implementation in pure Rust and an implementation using OSGeo PROJ (available through the gridpoints-proj feature) have been newly added.) (PR #238)
  • Template 3.30 (Lambert conformal) (A built-in implementation in pure Rust has been newly added. The implementation using OSGeo PROJ remains available through the gridpoints-proj feature.) (PR #236)

Enhancements

• An API for implementing coordinate transformations based on projection methods in pure Rust has been added as the projection module. Currently, only the Mercator and Lambert conformal conic projections are available. (PR #219, PR #235)
• Decoding performance for data encoded using simple packing has improved by about 12.5%. (#220 (thanks @​amoutiers), PR #221 (thanks @​amoutiers))

Enhancements to the CLI application gribber

• The CLI now uses less memory and performs less unnecessary work when decoding:
  • Latitude/longitude coordinates are no longer computed for binary exports. (#224 (thanks @​amoutiers), PR #225 (thanks @​amoutiers))
  • Decoded values in text exports are streamed without being collected first. (#233 (thanks @​amoutiers), PR #234 (thanks @​amoutiers))
• CLI input and output buffering has been improved:
  • Regular input files are read through a buffered reader instead of being loaded entirely into memory. (#229 (thanks @​amoutiers), PR #232 (thanks @​amoutiers))
  • Standard output is buffered for binary exports. (#227 (thanks @​amoutiers), PR #231 (thanks @​amoutiers))

Versions

grib 0.18.3
grib-cli 0.18.3

[0.18.2] - 2026-08-29

New supports

• Reading, accessing, dumping, and writing section/template parameters:
  • Templates 5.50002 (defined by Météo-France) (#140, PR #218)

Fixes

• Fixed support for templates 3.2, 3.3, 3.10, 3.41, 3.42, and 3.43. Although template structs were defined, they were not linked to Section3Payload.
