Update to 0.10.3: - refactor: rearrange the project to the src/ layout (https://todo.sr.ht/~mcepl/pygn/7) - Fix also pyproject.toml to generate what seems right. - Add the explicit dependency on nntplib for Python >= 3.12 (gh#python/cpython!104894). - Use email.policy.SMTP to be perfectly conforming with RFCs. Perhaps fixes: https://todo.sr.ht/~mcepl/pygn/6 - Rename README to README.md - Switch hosting of the project to Sourcehut. - Also add the text of GPLv3. - When sending nntp message fails, log the message to temporary file. - Convert documentation from .maff to plain HTML. - Parse email messages from binary files (Fixes #24 on GitLab) (see also gh#python/cpython#69731 and gh#python/cpython#85479)
