RESKit - v0.5.0

RESKit v0.5.0 Release Notes

Release Date: July 10, 2026
Previous Version: v0.4.4 (June 25, 2026)

✨ New Features & Workflows

• ERA5 weather-data preparation pipeline: A new download_and_process function that downloads, processes, and tiles all ERA5 variables required by a given workflow in a single call. It is source-agnostic, supports both wind and solar workflows, accepts lists of workflows, stores processed variables in a dedicated /processed subfolder, and is robust to tiles crossing the antimeridian. New example notebooks cover ERA5 wind/solar preparation and manual downloads (#277, resolves #155).
• Optional long-run-average adjustment in wind_config: A new enable_lra_adjustment boolean parameter lets you skip the long-run-average wind-speed adjustment. When set to False, all LRA-related parameters have no effect (#287, resolves #214).

⚠️ API Changes

• wind_config gains a required enable_lra_adjustment argument. Existing code that calls wind_config directly must pass this parameter (True reproduces the previous behavior).

🧪 Tests, CI & Docs

• README updated to document the new download_and_process function and the updated manual-download notebook.
• Updated Codecov require_changes configuration (#289).

📦 Dependency Updates

• pvlib minimum raised to ≥0.10.0 (from 0.9.0, range >=0.10.0,<=0.15.2) to pick up upstream bugfixes; test values for module_dc_voltage_at_mppwere adapted following pvlib'sv_oc` roundoff fix (pvlib GH1780 / GH1782) (#283, addresses #172).
• pip upper bound bumped to <=26.1.2 (#273).

RESKit - v0.4.4

RESKit v0.4.4 (2026-06-25) — changes since v0.4.3 (2025-11-21)

✨ New Features & Workflows

• Snow data from ERA5: ERA5 weather source can now read snow variables (albedo, density, depth, snowfall) (#278)
• Evaporative cooling workflow: new workflow to simulate water loss of evaporative cooling systems (#213)
• Wind-speed fallback: allow falling back to an alternative wind-speed source when the primary is unavailable (#266)

🐛 Fixes

• Adapt interpolateValues calls to the stricter GeoKit API (#282)
• Make ERA5 reading compatible with directly reading u/v wind component data (issue #115) (#221)
• Fix crash when execute_workflow_iteratively is run twice (issue #212) (#230)
• Validate that a realistic turbine capacity is supplied by the user (issue #217) (#231)

🧪 Tests, CI & Docs

• CSP workflows: independent test data, removed hard-coded cluster paths, fixed docstrings/documentation tests (#189, #131)
• Verify/check example notebooks (issue #114) (#232)
• Replace deprecated GitHub workflows with new testing workflows (#238); enable Codecov coverage on push (#254)
• README: update installation instructions, Zenodo + NumPy-style badges, and BibTeX entry for the ETHOS.RESKit.Wind Nature Communications publication (#223, #224, #209)

📦 Dependency Updates

RESKit - v0.4.3

This is the first release since RESKit development went fully public and moved entirely to GitHub.
All Issues were migrated from an internal GitLab instance.

1. Features and Enhancements:

• Simulation workflows for direct air capture (DAC) were added: Add DAC workflow to RESKit & Add Air Cooling Workflow to RESKit
• Pandas 2 is now supported: 133 update to pandas2
• Added alternative projection of wind speeds to hub height for wind workflow by using the the Global Wind Atlas for vertical interpolation: adapt hub height scaling function
• Updated wind speed and capacity factor correction files for wind_era5_PenaSanchezDunkelWinklerEtAl2025 to match scientific publication that will be published soon Version used for wind workflow publication
• Tests were added the ICONLAM-based wind workflows: add tests for ICONLAM workflows

2. Bugfixes:

• adapt lat limits to 90deg
• Reskit v.0.3.0 is broken
• Remove ivcurve_pnts
• Switched to RegularGridInterpolator for interpolation.
• adapt lat lon checks

3. Documentation & Code Structure

• Change formater to ruff
• Add ruff as formatting and linting tool
• 199 create a readthedocs documentation

4. Dependencies and Pipeline

• Support Newer Versions of Scipy
• Test Valid Dependency Range for RESKit 4.3
• Update Scipy and Papermill requirements
• Fix push to dev
• Setup GitHub test pipeline
