What is Courier?

Courier is turning its notification API into a full messaging orchestration platform.

Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.

What is Pixelfed?

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

Courier is turning its notification API into a full messaging orchestration platform.

◆ Current state

Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.

◆ Where it's heading

The build order is clear: ship the orchestration core first (Journeys, Design Studio, the MCP-aware CLI), then make it production-grade for larger teams. The last quarter is about optimization and governance — experiments, custom environments, decoupled routing — rather than net-new channels. AI is being threaded in as a feature, like localization, not a headline product.

◆ Prediction

Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.

P5.0

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

◆ Current state

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

◆ Where it's heading

Pixelfed has moved quickly through 0.14.5 and 0.15 with federation fixes and new APIs, and now an upstream security patch. The notes say heavy refactoring will continue toward a Nuxt-based web UI, so the near term is more churn in the front end.

◆ Prediction

Expect more 0.15.x patches for regressions from the refactor, with the Nuxt web UI as the next visible milestone.
