+**IMPORTANT**:

+- Minimum Python language version is now 3.8.
+- Python 3.6 and 3.7 support dropped, as these language versions have officially reached end-of-life. Code has not been fully cleaned of historical cruft yet, so parts of it may still work in these versions.
+- 3.8 becomes EOL after October 2024, so support for that version might be dropped soon, too.
