Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Proper way I think is to make a recipe/conda_build_config.yaml file with:

# https://github.com/conda-forge/conda-forge-pinning-feedstock/blob/main/recipe/conda_build_config.yaml

libgdal:
  - '3.10'
libgdal_core:
  - '3.10'

then re-render.
