Changelog#

Versions follow Semantic Versioning (<major>.<minor>.<patch>).

Backward incompatible (breaking) changes will only be introduced in major versions with advance notice in the Deprecations section of releases.

gcages v0.14.0 (2026-02-05)#

🐛 Bug Fixes#

  • Fixed Biochar and Soil Carbon Management accounting in the CMIP7 ScenarioMIP pre-processing. Soil carbon removal is now subtracted from AFOLU|Land|Land Use and Land-Use Change while biochar from `AFOLU|Land|Other. (#42)

🔧 Trivial/Internal Changes#

gcages v0.13.0 (2025-12-02)#

⚠️ Breaking Changes#

  • Additional CDR split#

Improved CDR granularity adding the Biochar and Soil Carbon Management new componentes from the Carbon Removal tree. (#40)

gcages v0.12.0 (2025-10-10)#

⚠️ Breaking Changes#

  • Split out the Carbon Removal variable tree in a way that better facilitates downstream spatial downscaling. This means that we no longer split out Carbon Removal|Geological Storage|Other Sources and Carbon Removal|Geological Storage|Synthetic Fuels, and have created four new gridding sector components:

  • Other CDR (based on the emissions tree)

  • Enhanced Weathering, Direct Air Capture, Ocean (based on the carbon removal tree)

(#39)

gcages v0.11.0 (2025-07-23)#

⚠️ Breaking Changes#

  • Updated minimum supported version of scmdata to v0.18.0. As a result, we could also drop the pin of xarray (as scmdata v0.18.0 fixes xarray compatibility issues, see https://github.com/openscm/scmdata/blob/main/docs/source/changelog.md). (#38)

🔧 Trivial/Internal Changes#

gcages v0.10.1 (2025-07-17)#

🐛 Bug Fixes#

  • Added explicit requirement on importlib-resources for running the AR6 setup as this seems to be needed to make things work on MacOS with Python 3.10 and 3.11 (#37)

gcages v0.10.0 (2025-07-16)#

⚠️ Breaking Changes#

    • Renamed the extra "cmip7_scenariomip" to "cmip7scenariomip"
  • Stopped packaging the tests as part of releases (this significantly reduces the size of the distributions)

(#35)

🐛 Bug Fixes#

    • Fixed the dependencies required for running the AR6 setup
  • Made it possible to run the AR6 setup on windows

(#35)

🔧 Trivial/Internal Changes#

gcages v0.9.0 (2025-07-16)#

⚠️ Breaking Changes#

    • Changed CMIP7 ScenarioMIP pre-processing. Carbon removal variables are now pre-processed into the Emissions tree, rather than being kept separate as part of the Carbon Removal tree. This greatly simplifies downstream use as all variables are in one tree.
  • Updated to requiring pandas-openscm>=0.5.1

(#30) - Updated minimum numpy version to 1.26.0, the earliest that is not in end-of-life. Fixed the numpy pin for Python 3.13 to >=2.1.0, the first numpy version which supported Python 3.13. (#34)

🎉 Improvements#

🔧 Trivial/Internal Changes#

gcages v0.8.0 (2025-07-12)#

⚠️ Breaking Changes#

  • Reverted the addition of a CO2 AFOLU gridding sector in CMIP7 ScenarioMIP pre-processing. (#29)

gcages v0.7.0 (2025-07-11)#

⚠️ Breaking Changes#

  • Managed the removal of subsectors for Emissions|CO2|AFOLU tree (#23)
  • Introduced the handling of the Carbon Removal tree (#25)

🐛 Bug Fixes#

  • Moved in Agriculture input sectors previously accounted in Agriculture Waste Burning (#18)

gcages v0.6.1 (2025-07-10)#

This release included the changes for the v0.7.0 release, but was released with the wrong version number.

gcages v0.6.0 (2025-05-04)#

⚠️ Breaking Changes#

🐛 Bug Fixes#

  • Fixed processing of aneris-based harmonisation overrides in the case where they are specified for some but not all scenarios (previously, the overrides would be filtered to an empty pd.Series and then an error would occur later in the workflow) (#16)

gcages v0.5.0 (2025-05-03)#

⚠️ Breaking Changes#

🆕 Features#

gcages v0.4.0 (2025-04-29)#

🆕 Features#

gcages v0.3.0 (2025-04-15)#

🆕 Features#

📚 Improved Documentation#

  • Added a demonstration of simple climate model running and post-processing to the AR6 workflow docs (#13)

gcages v0.2.1 (2025-04-14)#

📚 Improved Documentation#

  • Added missing tutorial to the navigation bar in the docs (#12)

gcages v0.2.0 (2025-04-14)#

⚠️ Breaking Changes#

  • Updated to use gcages naming conventions throughout (#10)
  • Simplified the renaming API, now all that is needed (and available) is [gcages.ar6.renaming.convert_variable_name] and [gcages.ar6.renaming.SupportedNamingConventions]. Replace calls to old functions like convert_gcages_variable_to_iamc(variable) with convert_variable_name(variable, from_convention=SupportedNamingConventions.GCAGES, to_convention=SupportedNamingConventions.IAMC). (#11)

🆕 Features#

(#11)

🎉 Improvements#

  • Added gcages.typing to help clarify the kind of data we expect throughout. (#6)

📚 Improved Documentation#

  • Added docs on renaming and added a section on naming to the docs on how to run the AR6 workflow (#10)
  • Added a demonstration of infilling to the AR6 workflow docs (#11)

🔧 Trivial/Internal Changes#

gcages v0.1.0 (2025-02-07)#

No significant changes.
