July 2025 – Earthkit-data: Focused on evaluating and laying groundwork for device-transfer capabilities in the Earthkit Xarray integration. Implemented an experimental to_device function in the Earthkit Xarray accessor to move DataArray/DataSet to compute devices (e.g., PyTorch, CuPy, JAX) via a backend-specific transfer helper. The feature was added for evaluation but subsequently disabled to ensure stability in production and to avoid untested data movement. Commits relevant to this work include an addition (537c1c13625b74a14c7de444aff791dbb8b2733b) and a later disablement (91381b8a9bd10079baf558c1feae685d0487b342).

May 2025 monthly summary for ecmwf/downstream-ci: Delivered targeted CI and dependency management improvements that reduce build complexity and enable faster feedback loops. Implemented a shallow dependencies approach to control and simplify workflow generation and dependency resolution, aligning with efficiency and reliability goals. Enhanced Earthkit-hydro integration by migrating dependencies to shallow_deps and adding debugging support, including a configuration_path placeholder to aid troubleshooting in downstream CI. Key outcomes include clearer dependency graphs, potential build-time optimizations, and improved debugging capabilities for CI pipelines, contributing to faster, more reliable release cycles and easier maintainability in downstream CI workflows.
