What is Rspamd?

Rspamd is rebuilding its neural filter into a pluggable framework — and just fixed a controller that accepted any password.

The 4.1.x series has moved fast on two fronts. The neural plugin gained pluggable feature-provider and ANN-architecture registries, multi-head attention pooling, slice and concat graph transforms, and a static_embed provider running a WordPiece subword tokenizer over a static embedding matrix. Separately the fuzzy subsystem got structured match results with a diagnostics API, Redis-persisted shingle sets and per-hash introspection. 4.1.4 in July fixed a critical controller bug where a malformed password hash caused it to fail open and accept any password, alongside a set of PCRE2 leaks and unbounded-match conditions in the regexp engine.

What is Apprise?

Apprise passed 150 notification services and taught tags to carry priority.

Apprise is a Python notification library that normalizes delivery across services behind a single URL syntax, and it now supports more than 150 of them. Recent releases pair a steady intake of new services — Stackfield, PushWard, MailerSend, Kook, IRC, Fluxer, Viber Bot, a restored XMPP via Slixmpp — with structural work: HTML to Markdown conversion built in, weighted tag routing, and a documentation and URL Builder site at appriseit.com that several releases were explicitly staged to enable.

Rspamd is rebuilding its neural filter into a pluggable framework — and just fixed a controller that accepted any password.

◆ Current state

The 4.1.x series has moved fast on two fronts. The neural plugin gained pluggable feature-provider and ANN-architecture registries, multi-head attention pooling, slice and concat graph transforms, and a static_embed provider running a WordPiece subword tokenizer over a static embedding matrix. Separately the fuzzy subsystem got structured match results with a diagnostics API, Redis-persisted shingle sets and per-hash introspection. 4.1.4 in July fixed a critical controller bug where a malformed password hash caused it to fail open and accept any password, alongside a set of PCRE2 leaks and unbounded-match conditions in the regexp engine.

◆ Where it's heading

The neural work is the strategic thread: turning a fixed classifier into a registry where feature extraction and network architecture are both swappable is what lets learned filtering evolve without forking the daemon. Around it, the project is systematically bounding resource use under adversarial input — regexp heap limits, zip-bomb extraction caps, per-message word budgets, a Lua URL filter consulted twice per field instead of once per byte. The front end is being simplified in the opposite direction, with jQuery, Font Awesome and FooTable all removed outright.

◆ Prediction

The registries and the static embedding provider arrived one release apart, so the piece not yet visible in these notes is a shipped model that uses them. Whether Rspamd distributes one or leaves it to operators is not indicated here.

Apprise passed 150 notification services and taught tags to carry priority.

◆ Current state

Apprise is a Python notification library that normalizes delivery across services behind a single URL syntax, and it now supports more than 150 of them. Recent releases pair a steady intake of new services — Stackfield, PushWard, MailerSend, Kook, IRC, Fluxer, Viber Bot, a restored XMPP via Slixmpp — with structural work: HTML to Markdown conversion built in, weighted tag routing, and a documentation and URL Builder site at appriseit.com that several releases were explicitly staged to enable.

◆ Where it's heading

Two lines are converging. Breadth is the obvious one and it compounds monthly, but the more interesting shift is from a fan-out library to one that makes routing decisions: tags now carry weights, and delivery attempts cascade by priority rather than firing at everything at once. The tooling investment — details() as JSON, plugin definition cleanup, the URL Builder — reads as an effort to make that growing service catalog navigable to people who won't read 150 sets of docs.

◆ Prediction

Expect the monthly cadence of bundled service additions to continue, and the weighted-routing model to accumulate configuration surface now that ordering is a first-class concept. The repeated groundwork commits suggest more of the documentation site's functionality is still being backfilled.
