mailcow's monthly releases are mostly upstream security updates with small UI work
mailcow ships named monthly releases with lettered revisions, and most exist to pull in upstream security fixes for components like SOGo, Nginx, Redis, Unbound and Rspamd. The September release also added an ACL and global switch to stop external alias forwarding, a show-password toggle on login pages, and fixes such as an auth-cache wipe during nginx outages. October moved PHP to an Alpine 3.24 base and brought SOGo 5.12.12, Nginx 1.30.6 and a UI update.
Superhuman gives team admins a console and Enterprise a usage report that counts MCP.
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. October's mobile batch added Compact Mode, swipe actions and attachment-aware AI, and the iOS app now fits iPhone Duo. The newest release adds a team admin console on all plans and an Enterprise-only Team Activity page.

Keeping a dozen bundled upstreams current is the product, and the cadence is built around that. Feature work arrives in small admin and web UI controls alongside the security updates.
Expect a revision of the October release carrying further upstream updates, following the lettered-revision pattern.

The product is moving from a single-user power tool toward something a company buys and administers. Seat counts, join approvals, billing and role changes now live in one place, and Team Activity reports which members use desktop, mobile or the MCP and whether they touch AI and collaboration features. That is the reporting a buyer needs to justify renewals.
Expect more Enterprise-gated controls built on Team Activity, such as usage-based seat management or policy settings for AI and MCP access. The entries do not show pricing changes, so the timing of any upsell is unclear.
