What is Chatwoot?

Chatwoot is turning its June voice launch into a channel a team can actually run.

Voice, introduced in June, now has a dedicated Calls area with filtering by inbox and assignee, per-call status and recordings playable in place, instead of calls buried inside conversation threads. Captain, the AI agent, mines already-resolved conversations for suggested FAQs and refreshes its own documents. Reporting charts became clickable, leading from a metric straight to the conversations that produced it.

What is mailcow?

mailcow's release notes are almost entirely upstream security currency.

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

Chatwoot vs mailcow: editorial side-by-side

C6.3

Chatwoot is turning its June voice launch into a channel a team can actually run.

◆ Current state

Voice, introduced in June, now has a dedicated Calls area with filtering by inbox and assignee, per-call status and recordings playable in place, instead of calls buried inside conversation threads. Captain, the AI agent, mines already-resolved conversations for suggested FAQs and refreshes its own documents. Reporting charts became clickable, leading from a metric straight to the conversations that produced it.

◆ Where it's heading

The pattern is consolidation rather than expansion. Each recent release takes something Chatwoot already shipped and adds the surface a daily operator needs: a home for calls, a payoff view for Captain, a path from a report number to the underlying threads. The AI work is aimed at reducing manual upkeep of the knowledge base rather than at answer quality.

◆ Prediction

Voice is the obvious place for the next round of automation parity with text, since this release gave it a dashboard but not workflow triggers or Captain participation.

5.0

mailcow's release notes are almost entirely upstream security currency.

◆ Current state

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

◆ Where it's heading

For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.

◆ Prediction

Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
