What is Stalwart?

Stalwart keeps hardening its JMAP stack while moving early on emerging email-auth standards.

Stalwart is an all-in-one mail and collaboration server — JMAP, IMAP, SMTP, CalDAV and OIDC in one binary — shipping point releases every week or two. The last five releases pair an aggressive JMAP conformance drive with steady expansion of standards coverage. It reads as a project optimizing for correctness and completeness rather than new product surface.

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.

Stalwart vs The Events Calendar: editorial side-by-side

S5.0

Stalwart keeps hardening its JMAP stack while moving early on emerging email-auth standards.

◆ Current state

Stalwart is an all-in-one mail and collaboration server — JMAP, IMAP, SMTP, CalDAV and OIDC in one binary — shipping point releases every week or two. The last five releases pair an aggressive JMAP conformance drive with steady expansion of standards coverage. It reads as a project optimizing for correctness and completeness rather than new product surface.

◆ Where it's heading

Two arcs run in parallel: closing JMAP spec gaps to pass conformance suites, and adopting fresh email-authentication standards (DKIM2, DMARCbis, VAPID web push) ahead of most competitors. Platform reach (FreeBSD) and at-rest encryption round out a hardening push. The direction is a standards-maximal, production-grade mail server, not a feature-led one.

◆ Prediction

Expect more 0.16.x point releases that finish the JMAP conformance work and stabilize the new DKIM2, DMARCbis and web-push paths, with fixes continuing to outnumber features.

T0.0

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.
