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 Subsplash?
Subsplash Giving now syncs donations and people with Planning Center.
Subsplash runs giving, media, people and workflow tools for churches. In November it made Dashboard Home a single view across all its products, then on 10 November connected Subsplash Giving to Planning Center: transactions sync one way on a schedule or on demand, profiles sync both ways, funds are mapped, and each sync produces a report with flagged items staff can fix themselves.

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.
Subsplash
5.0COMMS
Subsplash Giving now syncs donations and people with Planning Center.
◆ Current state
Subsplash runs giving, media, people and workflow tools for churches. In November it made Dashboard Home a single view across all its products, then on 10 November connected Subsplash Giving to Planning Center: transactions sync one way on a schedule or on demand, profiles sync both ways, funds are mapped, and each sync produces a report with flagged items staff can fix themselves.
◆ Where it's heading
Recent work focuses on the church office's admin load: notes, multi-select, reconciliation, a unified home page, and now integration with the people database many churches already use. Subsplash is positioning Giving to work alongside Planning Center rather than requiring churches to replace it.
◆ Prediction
Further Planning Center links, such as events or groups, are plausible, but the entries do not indicate which comes next.
