Fonoster
Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
A side-by-side editorial comparison of Courier and Pixelfed — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Pixelfed's 0.15 candidate adds an account-delete API and drops PHP 8.3.
Pixelfed has two release candidates out in October. 0.15.0-rc1 raises the hashtag follow limit from 25 to 100, adds an account deletion API route, fixes timelines for Mastodon clients, rejects follows to moved accounts and drops PHP 8.3. 0.14.5-rc1 fixed boost federation and added FEP-6757 support. The September 0.12.12 release changed captcha and locale environment variables.
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.
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.
Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.

Most of the work is federation correctness and Mastodon-client compatibility, paired with large dependency upgrades across Laravel, Symfony and Guzzle. Breaking environment and runtime changes are arriving in clusters, so self-hosters face more upgrade steps per release.
Expect 0.15.0 stable after the RC, with more Mastodon API compatibility fixes. The entries don't show bigger product changes.
