# TODO: Temporarily vendored from mamba.utils v0.19 on 2021.12.02
# Decide what to do with it when we split into a plugin
# 2022.02.15: updated vendored parts to v0.21.2
# 2022.11.14: only keeping channel prioritization and context initialization logic now
# 2024.09.24: parameterize init_api_context
