the test suite with recent versions of SQLAlchemy.
Introduce PEP 517 compliant build.

2024.1 (2024-02-21): Fix unit tests packaging problem.

support server connections which require the use of STARTTLS.

2022.0 (2022-03-31): Simplified database initialisation is now possible via HTTP POST and a JSON payload.

2022.1 (2022-05-20): Request content type verification now works if additional parameters like "charset" are passed.

Autodiscover response because automx2 always returned "on", which is the default value if the element is absent.

2021.5 (2021-10-04): Existing versions auf automx2 return "do not use SSL" for socket types other than SSL and STARTTLS.
This previously undocumented behaviour can cause unexpected results. Future automx2 versions will terminate automx2
when encountering invalid socket type strings in the database. The current release logs an error to notify users of
the upcoming change.
This release also improves the Mobileconfig generator, making it smarter when choosing among multiple servers defined
in the database.
