A side-by-side editorial comparison of Amelia and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
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.
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.

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.
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.

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.
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.
