February 2026 monthly summary for ecmwf/gribjump: GRIB API modernization implemented by migrating from CodesHandle-based code paths to use CodesHandle directly, eliminating dependencies on codes::GribHandle and codes::GribAccessor. This refactor improves integration with the ECMWF Codes ecosystem, enhances performance, and simplifies maintenance. Key commit: d559ad1686fd84484b31a45afc14a85d8e3afd37 (Remove codes::GribHandle and codes::GribAccessor; Fixes METK-144).

January 2026 (2026-01) monthly summary for the ecmwf/metkit project. Focused on refactoring for maintainability, API enhancements to improve data handling, and robust error handling.

Month: 2025-11 highlights architectural refinements across metkit and fdb, focusing on decoder modernization, Codes API robustness, and code cleanliness. Major changes include removing CodesDecoder from BUFRDecoder and GRIBDecoder, decoupling the decoding stacks, moving DataContent to a centralized location, and tightening CodesHandle integration and error reporting. In fdb, the patch tool was refactored to use CodesHandle and CodesContent for improved efficiency and clarity. These efforts reduce technical debt, enable future performance gains, and strengthen debugging and traceability, delivering business value through easier maintenance and faster feature delivery.

October 2025 monthly summary focused on delivering a safer, more ergonomic interaction with METKIT's GRIB/BUFR tooling and accelerating CI feedback cycles across downstream CI. The work combined API modernization in the metkit repository with reliability improvements in CI pipelines, delivering tangible business value through safer code, faster validation, and more scalable test execution.

January 2025 (ecmwf/downstream-ci): Strengthened CI and packaging alignment to enable seamless adoption of pymultio. Updated CI configuration to include pymultio support, refactored workflow references and dependencies from multio-python to pymultio, and committed as part of the month’s delivery.
