Oct 1, 2025October 2025 landlab work summary: DepthDependentDiffuser UX improvements, a documentation build workflow fix, and CI/tooling modernization to improve stability and security. Key outcomes include clearer deprecation behavior when both linear_diffusivity and soil_transport_velocity are provided, updated docstrings marking linear_diffusivity as optional/deprecated, and simplified warning formatting; a fix to rename the nox docs build session from build-docs to docs-build; and modernized dependencies and CI tooling (cibuildwheel 3.2.1; numpy 2.3.3/2.3.4; scipy 1.16.2; matplotlib 3.10.7; pandas 2.3.3) to improve reliability and security. Overall impact: better user guidance, more robust builds, and easier future maintenance. Technologies/skills demonstrated: Python, docstring discipline, deprecation handling, nox/CI workflows, and dependency management.
