A side-by-side editorial comparison of Mattermost and NetNewsWire — release velocity, themes, recent moves, and the top alternatives to consider.
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
NetNewsWire 7.3 ships its first newsprint-style themes on both Mac and iPhone.
NetNewsWire 7.3 is shipping on iOS while the Mac version reaches beta 8. The cycle has handed layout to users: feed icon visibility, grayscale icons, fading read articles, hidden smart feeds and dedicated Mac settings panes. The latest builds add Gray and Plum themes plus a grayscaleIcon key that lets any theme render feed icons and avatars in gray, alongside timeline crash and sidebar fixes.

Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.

The latest builds add Gray and Plum themes plus a grayscaleIcon key that lets any theme render feed icons and avatars in gray, alongside timeline crash and sidebar fixes.
7.3 started with media support and moved into appearance control; theme authors now get the same switches users have. Mac betas and iOS builds land on the same days with the same features, so the two apps are being kept in step rather than the Mac leading.
Expect a final Mac 7.3 release soon, as recent betas are mostly theme additions and crash fixes; the entries give no sign of what 7.4 targets.
