Jun 1, 2026June 2026 highlights focused on correctness and maintainability within cosipy (cositools/cosipy). Key deliverable: fixed indentation of EventSelectorInterface._select, ensuring it is properly defined as part of the interface. This correction reduces the risk of misimplementation in downstream event selection logic and improves code readability and interface contract clarity. No new user-facing features were released this month; instead, this work strengthens the foundation for reliable event handling and future enhancements.

Sep 1, 2025September 2025 (2025-09) summary for cosipy focused on performance, accuracy, and developer productivity. Key feature deliveries include migrating TS map computations from the legacy TSMap to the actively maintained FastTSMap, which improves runtime performance and maintainability. Earth occultation calculations were stabilized by standardizing parameter naming across functions, docstrings, and internal calls, reducing inconsistencies. The orbital information data reference was updated to point to a new file containing orbital data, enhancing pipeline accuracy. A ParallelImageDeconvolution framework was introduced to enable parallel processing, with CLI enhancements, improved MPI handling, and data interface documentation, significantly increasing scalability. The MAP_RL deconvolution option was restored to preserve feature parity and avoid regression. These changes collectively drive better data fidelity, faster processing of large datasets, and improved developer experience.
