March 2025 delivered a robust satellite data processing workflow, comprehensive documentation updates, and enhanced test coverage, driving data reliability, release readiness, and developer velocity. Key outcomes include Satellite Data Integration (footprint lookup, data store population, scenario checks) with 1ms footprint alignment tolerance; a new processing path for continuous=false with input_frequency handling and targeted tests; time unit handling improvements for varying periods; and the addition of a set_period_str utility. Documentation and changelog updates were completed across modules, and test infrastructure was strengthened (conftest for modelscenario, satellite-related tests, and stability fixes). An experimental Add Obs Column feature was implemented and subsequently reverted to preserve stability.

February 2025 — openghg/openghg: Implemented comprehensive region handling improvements and input flexibility with a focus on reliability and business value. Key features delivered include: (1) Region argument support and standardization across defaults.json, obscolumn, and core logic, with migration to fp_region and obs_region naming. (2) Site and satellite argument integration in the parser and read-file flows, with defaults loosened to support optional site. (3) Site/Satellite optionality and domain/fp_region key handling, enabling either site or satellite input and dynamic key creation. (4) Broad code-quality and typing improvements: removal of legacy type hints, mypy/type-check fixes, extensive formatting (Black/flake8-compatible), and typo fixes. (5) Tests, data, and documentation upgrades: expanded test data, new tests, parser/test realignments, and changelog/API documentation cleanup. Additional maintenance included reverting an unintended default-period change, removing the force flag, and refining domain-footprint validation and edge-case handling.
