Behavorial changes

• migration:* commands are not available anymore (unless in debug). See Remove the migration commands unless in debug mode #27113 for information. If you thought you needed them, feel free to ping the author or a reviewer of the PR to solve the problem correctly. Running migrations directly mostly breaks the database status and is therefor only ment for debugging faulty migrations.
• The JSON log format no longer contains full exception in the message field, but adds a separate exception entry is added and the existing message will only contain the exception message text. This might need adjustments by administrators when logs are extracted to external sources.
• EHLO for SMTP connections is now generated from overwrite.cli.url: Set local domain for swiftmailer #27306

Boolean database fields can not be NotNull anymore #24055

You can fix your app in the same way we fixed Talk nextcloud/spreed#5445

The end of support for the database.xml should definitely be in here. Causes marius-wieschollek/passwords#390

Maybe it would be worth mentioning that the Circles app changed a lot. The frontend JS API got replaced by OCS API routes and the backend PHP API also changed significantly. Developers who interact with Circles probably need to migrate their code.

nextcloud/documentation#6900 for the collected changes. Please help review.

I'll leave that to the developers of the app.
