Fonoster
Fonoster ships four releases in a day to make linking a Twilio number a single step.
A side-by-side editorial comparison of mailcow and Tawk.to — release velocity, themes, recent moves, and the top alternatives to consider.
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.
tawk.to's widget 4.4.0 turns to keyboard and screen-reader fixes after a run of form work.
tawk.to is a free live chat widget that ships a version every few weeks, mostly fixes with periodic capability additions. The 4.x line added two JavaScript APIs in September and per-country phone length checks in 4.3.0. Widget 4.4.0 adds a close button inside round widgets and fixes keyboard, focus-outline and screen-reader issues, plus custom chat buttons that failed on sites asking for consent.

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.
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.

Recent work splits between developer hooks for host sites, data quality in visitor forms, and now accessibility: 4.4.0 is mostly about the widget working without a mouse. The consent-site fix continues the privacy thread from 3.6.0. Nothing in the entries points to a change of direction.
Expect more accessibility and form fixes in 4.x point releases; the entries do not show anything larger on the way.
