Backend.AI GO v1.6.1

10 commits since v1.6.0. (15461 lines added, 146 lines deleted)

New Features

  • OS credential vault integration — API keys, secrets, and inference credentials are now stored in the operating system's native keyring (macOS Keychain, Windows Credential Manager, Linux Secret Service) instead of plain text on disk.
  • Connector trait and capability model design — Foundational trait abstraction for plugging in new external integrations with declared capabilities.
  • Conversational guardrail model primitives and storage — Configurable safety boundaries for chat with reusable storage shared across agents.
  • Per-agent, per-day, per-tool spending and rate limits — Fine-grained controls let operators cap cost and usage by agent, day, and individual tool, with a persisted ledger and replenishment engine.
  • Reversible-by-design action audit schema — Every recorded action carries the metadata needed to undo it, laying the groundwork for safe automated rollbacks.
  • Step reasoning retention and display — Each agent's chain-of-thought is preserved across runs and surfaced in the run detail view so you can replay how an answer was reached.

Improvements

  • What's New modal content refreshed across all six locales (English, Korean, Japanese, Spanish, Traditional Chinese, Simplified Chinese) with v1.6.1 highlights.
  • CHANGELOG and README Recent Updates section refreshed for the v1.6.1 maintenance release.

Bug Fixes

  • aarch64 Linux build restored after toolchain regressions, and the Squad monitor re-render loop that caused runaway re-renders on active squads has been eliminated.
  • Container CLI check parser correctly handles the updated container-cli output format.
  • Squad workspace self-heal automatically recovers from inconsistent or partial workspace state on launch.
  • Tauri runtime startup panic in spawn agent limits init resolved by binding the limits initializer to the Tauri runtime.

CI/CD Improvements

None.

Technical Details

  • OS credential vault uses the existing keyring crate with platform-specific backends (apple-native, windows-native, sync-secret-service).
  • Conversational guardrail and reversible action audit work introduces new SQLite tables and schema migrations.
  • Spending and rate-limit ledger is persisted per agent with daily and per-tool quotas managed by a dedicated rate-limit engine.
  • Step reasoning is stored alongside each agent step so it survives across run boundaries and is rendered in the run detail view.
  • Connector trait and capability model are pure design scaffolding in this release; no user-visible connector is enabled yet.

Dependencies

None.
