About Stalwart
Stalwart keeps filling in mail-standard gaps with a steady maintenance release
Stalwart is an all-in-one mail and collaboration server, and v0.16.10 is a characteristic release: a cluster of standards-compliance and configuration additions — IDN support, OAuth public-client handling, an IMAP extension, ACME key reuse — rather than a headline feature. The single visible entry shows maintenance-mode breadth, not directional change.
