What is Amelia?

Amelia keeps widening from appointments into events, ticketing and payments.

Amelia is a WordPress booking plugin that announces each release as a blog post, roughly monthly. Across 8.5 through 9.7 the shape is consistent: appointments remain the core, but events take an increasing share — QR-code ticketing, invoicing, waiting lists, front-end display controls, and now public event pages in 9.7. Calendar integration and payment flexibility are the other steady threads, and 9.1 introduced Angie AI as an admin-side assistant alongside Outlook sync and Divi 5 support.

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.

Amelia vs mailcow: editorial side-by-side

Amelia
COMMS
2.5

Amelia keeps widening from appointments into events, ticketing and payments.

◆ Current state

Amelia is a WordPress booking plugin that announces each release as a blog post, roughly monthly. Across 8.5 through 9.7 the shape is consistent: appointments remain the core, but events take an increasing share — QR-code ticketing, invoicing, waiting lists, front-end display controls, and now public event pages in 9.7. Calendar integration and payment flexibility are the other steady threads, and 9.1 introduced Angie AI as an admin-side assistant alongside Outlook sync and Divi 5 support.

◆ Where it's heading

The product is growing into a light events-and-payments layer inside WordPress rather than a scheduling widget. The IvyForms integration is the tell on strategy: instead of building a form builder, Amelia delegates pre-booking data collection to a sibling product, which points at a suite rather than one plugin. Full data export and import arriving in 9.7 is the housekeeping a product needs once customers have years of bookings inside it — and once moving between installations becomes a support question.

◆ Prediction

Public event pages give Amelia a front end it did not previously own, so making those pages promotable or discoverable is the natural next step. These posts are summaries rather than changelogs, so specifics are hard to read ahead of time.

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.
