What's New
Major release adds ESP32 support and publishes 120 crates with breaking auth changes.
Breaking Changes
- Writes to /v1/pipeline/inject* and /internal/* now require authentication.
- Writes are gated until Firestore hydration completes.
New Features
- Added ESP32 decision firmware with INT8 support.
- Implemented OpenJev pipeline training.
- Added deterministic min-cut algorithm.
- Published 120 crates on crates.io.
Improvements
- Brain server graph rebuild latency reduced from 96s to 31ms p99.
- Brain server writes and training now wait for Firestore hydration.
- Brain server ranked search and sparsifier no longer hold graph lock.
Bug Fixes
- Fixed UTF-8 truncation panics in brain server.
- Brain server SSE image builds correctly with BRAIN_SYSTEM_KEY.
Upgrade Notes
Clients must update authentication for /v1/pipeline/inject* and /internal/* endpoints. Writes are now gated until Firestore hydration completes, which takes approximately 1 minute. Expect latency improvements in brain server graph rebuilds.
