Stalwart keeps filling in mail-standard gaps with a steady maintenance release

emailcollaboration-serverstandards-complianceoauthimapself-hosted
◆Current state
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.
◆Where it's heading
The work points at closing protocol gaps and smoothing operations — root redirects, ACME renewal key reuse, OAuth edge cases — to make Stalwart a drop-in replacement across more deployments. This is consolidation: widening compatibility so fewer environments hit a missing-standard wall.
◆Prediction
Expect continued point releases in the same vein: incremental RFC coverage and deployment-ergonomics fixes. With only one entry visible, there is no signal of a larger architectural shift.

    IDN support, OAuth public-client profile, IMAP extension

    v0.16.10 continues Stalwart's standards-compliance buildout: internationalized domain names, an OAuth profile for public clients with client-secret verification for confidential ones, plus HTTP root-redirect and ACME key-reuse options. Incremental hardening of an already broad mail-and-collaboration server rather than a new capability.
