What is Converse.js?

Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.

Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.

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.

Converse.js vs Rspamd: editorial side-by-side

C2.5

Converse.js 14.0.1 fixes OMEMO:2 group decryption broken by Chromium 153.

◆ Current state

Converse.js shipped 14.0.0 in June with OMEMO:2, the current revision of XMPP's end-to-end encryption, plus fixes that make encryption state and errors visible. 14.0.1 in October fixes OMEMO:2 group messages that stopped decrypting in Chromium 153, a bug that also skipped a sender check.

◆ Where it's heading

The project is in a stabilisation phase on the 14 line, with encryption correctness as the main concern. Releases are months apart.

◆ Prediction

Expect further 14.0.x patches for encryption and browser compatibility; no next major is signalled.

5.0

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.
