mailcow vs The Events Calendar
A side-by-side editorial comparison of mailcow and The Events Calendar — release velocity, themes, recent moves, and the top alternatives to consider.
mailcow vs The Events Calendar: at a glance
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 The Events Calendar?
The Events Calendar runs a disciplined maintenance train across its whole plugin suite.
The Events Calendar is a mature WordPress events and ticketing suite spanning several plugins — the core calendar, Event Tickets, Filter Bar, Community, and Pro add-ons. The recent release stream is almost entirely maintenance: bug fixes, translation updates, accessibility work, and payment-gateway handling for PayPal, Square, and Stripe. Development is spread evenly across the plugin family rather than concentrated in one flagship.
mailcow vs The Events Calendar: editorial side-by-side
mailcow
5.0COMMS
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.
The Events Calendar
0.0COMMS
The Events Calendar runs a disciplined maintenance train across its whole plugin suite.
◆ Current state
The Events Calendar is a mature WordPress events and ticketing suite spanning several plugins — the core calendar, Event Tickets, Filter Bar, Community, and Pro add-ons. The recent release stream is almost entirely maintenance: bug fixes, translation updates, accessibility work, and payment-gateway handling for PayPal, Square, and Stripe. Development is spread evenly across the plugin family rather than concentrated in one flagship.
◆ Where it's heading
This is a product in steady stewardship mode. The releases show a team keeping a large installed base stable — tightening capability checks for security, fixing pagination and view rendering, improving WooCommerce and Elementor compatibility — with no new capability surface in view. Accessibility and payment reliability are recurring focus areas.
◆ Prediction
Expect the same cadence of small, per-plugin maintenance releases to continue, with security hardening and gateway compatibility as the likely themes. Nothing in these entries signals a larger feature push.
