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.

What is Vonage?

Vonage's tracked feed shows only SDK version bumps, and it went quiet after October 2025.

Everything captured here is server-SDK release plumbing — Ruby, .NET, Java, Kotlin, Node, iOS — with no release notes beyond a version string and a date. Several rows are not releases at all but scraped navigation chrome from the changelog index, which means the parser is picking up page furniture alongside real versions. The most recent genuine entry is a Ruby SDK bump from October 2025.

mailcow vs Vonage: editorial side-by-side

mailcow
COMMS
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.

Vonage's tracked feed shows only SDK version bumps, and it went quiet after October 2025.

◆ Current state

Everything captured here is server-SDK release plumbing — Ruby, .NET, Java, Kotlin, Node, iOS — with no release notes beyond a version string and a date. Several rows are not releases at all but scraped navigation chrome from the changelog index, which means the parser is picking up page furniture alongside real versions. The most recent genuine entry is a Ruby SDK bump from October 2025.

◆ Where it's heading

Nothing about Vonage's actual product direction is visible through this source; the CPaaS platform work happens elsewhere, and only its client-library releases surface here. On the evidence available, the feed reflects routine multi-language SDK maintenance across a mature API surface rather than any shift in capability. The nine-month gap since the last captured release suggests the source itself has stopped updating rather than that Vonage stopped shipping.

◆ Prediction

Insufficient data for a directional call: the feed is stale and carries no release notes, so any prediction would be about the crawler rather than the product.
