v0.3.9 — 2026-05-28

Final pre-0.4.0 release focused on smarter memory briefing, cache-first context, tool-call repair, and cleaner CLI configuration.

Breaking Changes

  • Removed CLI .env behavior loading

    • Runtime settings now live in:

      ~/.config/brainrouter/config.json

    • API key env vars still supported

  • Removed native Anthropic provider

    • Claude now used through OpenAI-compatible providers
    • (OpenRouter, Together, Fireworks, etc.)

  • Removed CLI recall fallback wrapper

    • Brain-side recall pipeline now owns fallback logic

Highlights

  • Adaptive memory briefing

    • Smarter recall triggers for:

      • first turn
      • continuations
      • debug/file workflows
      • post-compaction
      • child-agent synthesis

  • New /briefing inspector

    • Shows:

      • recall reasons
      • queried/skipped sources
      • injected tokens
      • compaction savings
      • warnings

  • Cache-first context system

    • ImmutablePrefix
    • AppendOnlyLog
    • VolatileScratch

  • Prefix-pinned memory cards

    • Stable first-turn memory caching
    • /refresh-memory for intentional repins

  • Tool-call repair pipeline

    • Repairs malformed/truncated JSON
    • Extracts leaked tool calls from content
    • Prevents repeated identical calls

  • Model-tier escalation

    • <<<NEEDS_HIGH>>>
    • /tier flash|standard|pro|auto

  • Cost + cache telemetry

    • /tokens now shows:

      • turn/session cost
      • cache hit %
      • token savings

Other Improvements

  • Consolidated CLI config system

  • Externalized provider/model catalogs

  • Better LM Studio metadata support

  • Improved token estimation for:

    • CJK
    • code-heavy prompts
    • prose-heavy prompts

  • Slimmer provider picker UX

  • Hardened memory secret redaction

  • Stale/superseded memory warnings

Testing

  • Added briefing benchmark coverage

  • Added tests for:

    • cache stats
    • repair pipeline
    • pricing
    • config loading
    • tier escalation

Notes

0.3.9 intentionally does not yet include:

  • federation
  • durable agent queues
  • cross-CLI inboxes
  • vault mirrors
  • active-session registries

Those are planned for 0.4.x.
