Regression in File-based Mail Spool

A regression in these releases caused the FileSpool to reject and delete emails containing complex MIME structures (attachments, embedded files, or AbstractPart objects). This resulted in valid messages being lost from the mail queue.

A corresponding bugfix is available in the review system, new releases are planned to be published on January 20th, 2026.

No further database upgrades are required for these maintenance releases.
