Rspamd vs The Events Calendar
A side-by-side editorial comparison of Rspamd and The Events Calendar — release velocity, themes, recent moves, and the top alternatives to consider.
Rspamd vs The Events Calendar: at a glance
What is Rspamd?
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
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.

Rspamd
5.0COMMS
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
◆ Current state
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
◆ Where it's heading
Since 4.1, every release has hardened parsers and closed memory-safety and trust gaps; 4.3 applies the same pass to the authentication standards themselves (SPF, DKIM, DMARC, ARC) and to content extraction. Operators should expect scores and fuzzy hashes to shift after upgrading, because the project now favours spec-correct results over backward-compatible ones.
◆ Prediction
A 4.3.x point release fixing regressions from these behaviour changes is the likely next step, as 4.2.1 followed 4.2.0 within two weeks.
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.
