Oct 1, 2025October 2025 (2025-10): SciTools/iris delivered a major feature: NetCDF UGRID mesh compression using zlib. The initiative focused on enabling compression when saving UGRID meshes to NetCDF files, extending the save_mesh and Saver APIs to accept compression keyword arguments, and validating behavior through tests. No critical bugs were reported; stability maintained and groundwork laid for storage efficiency and faster I/O.

Sep 1, 2025September 2025 monthly summary for SciTools/iris: Delivered a feature enhancement to preserve masked auxiliary coordinates during aggregation operations (aggregated_by) and during collapse, ensuring masking information is retained in downstream analyses. Associated commits implemented the change and tests were updated to verify behavior; a release-note entry (whatsnew) was added to communicate the improvement. Also fixed flaky URL handling in the link checker by updating the .lycheeignore to ignore the gitwash URL, preventing false link-check failures and CI noise.

Apr 1, 2025April 2025 monthly summary for SciTools/iris focused on build system simplification and packaging modernization. The primary delivery was a feature enabling a leaner, more maintainable build process and better packaging metadata alignment with modern standards. Specific outcomes include removal of the linkcheck target from the documentation Makefile to simplify builds and reduce maintenance, and packaging updates to comply with PEP 639 by adding license fields, increasing minimum versions for setuptools and setuptools_scm, and adjusting classifiers to remove the specific BSD license. These changes improve downstream tooling compatibility, licensing compliance, and future-proof the project for releases. There were no critical bugs fixed this month; the work focused on tooling, build reliability, and maintainability, with clear business value in faster releases and reduced maintenance overhead.
