ARTS 2.6.20 release

[olemke]

ARTS 2.6.20 contains bug fixes for line-mixing absorption results for CO2 hot bands, O-6 partition function and sinefit baseline indexing in calcBaselineFit. Support for the MT CKD 4.3 continuum was added.

Changes since 2.6.18 can be found on the GitHub release page

Updated conda packages are also available. We recommend to install ARTS in Miniforge3 with mamba install -c rttools pyarts. Existing environments can be updated with mamba update -c rttools pyarts.

Conda packages are available for Python 3.11, 3.12, 3.13 and 3.14.

We do not provide conda packages for Python 3.10 anymore since it is EOL in October and the support for the conda-forge repository was already dropped in August.

Best wishes,
The ARTS Developers
