environment.yml currently specifies the minimum Python version as 3.8. However, xcube is no longer compatible with 3.9. For instance, commit e22e7fbad (2023-02-20) adds an import of functools.cache (only introduced in 3.9) to xcube/server/config.py. There doesn't seem to be any need to keep supporting 3.8, and there have been no complaints about this incompatibility so far, so all we need to do is bump the specifier in environment.yml to enforce and communicate the >=3.9 requirement.
To Reproduce
Steps to reproduce the behavior:
Install xcube from source in a Python 3.8 environment.
Run unit test suite.
Test run will already fail at import stage, since xcube is using language features and library imports that aren't available in Python 3.8.
