What's New
Major upgrade adds Kimi Code support and requires Node.js 24.11.0+.
Breaking Changes
- Node.js 24.11.0 or newer is required.
- Invalid agent credentials are now rejected with a 401 instead of falling back to anonymous local-user.
- Company brand color and per-company attachment size limit fields have been removed.
- Silent-run detection no longer performs automatic recovery actions.
New Features
- Kimi Code joins the adapter lineup as a first-class provider.
- Opt-in error monitoring with Sentry.
- Deterministic skill manifests for agents.
- Managed-sandbox-only mode to hide host-path surfaces.
Improvements
- The sandbox callback bridge is rebuilt on a bounded HTTP/2 transport to prevent failures.
- Operators can now control settings visibility using PAPERCLIP_HIDDEN_SETTINGS and PAPERCLIP_SETTING_DEFAULTS.
- Onboarding is simplified by removing the mission step and focusing on agent creation.
Bug Fixes
- Improved failure reporting for skill library determinism.
Upgrade Notes
Upgrade Node.js to 24.11.0 or newer before updating as it is now required. Review integrations for the credential change, as invalid tokens now return 401s instead of falling back to anonymous access. Check for usage of the removed company brand color and attachment size limit fields.
