## What's New in v0.0.21

v0.0.21 is a focused reliability release for SurfSense agents and chat infrastructure. It adds agent-side caches, fixes invalid prompt cache configuration paths, moves chat persistence to the server, and closes security leaks in manual authentication endpoints.

### Agent Reliability

- **Agent Caches**: SurfSense agents now use dedicated caches to reduce repeated work and make longer conversations more stable.
- **Prompt Cache Fixes**: Invalid prompt cache configurations are now handled correctly instead of creating brittle runtime behavior.
- **More Reliable Runtime State**: The caching improvements give agent turns a cleaner foundation for repeated tool use and prompt execution.

### Server-Side Chat Persistence

- **Chat Persistence Moved Server-Side**: Chat state persistence now lives on the server, reducing fragile client-side assumptions and improving consistency across sessions.
- **Cleaner Chat Continuity**: Server-owned persistence gives SurfSense a stronger base for future multi-agent and long-running chat work.

### No longer broken

- Fixed Docker deployment issues found after the previous platform upgrade
- Fixed manual authentication endpoint leaks
- Fixed invalid prompt cache configuration handling

### Developers

- Chat persistence responsibility moved from the frontend into backend-managed flows
- Agent cache plumbing was introduced as groundwork for faster, more resilient agent turns
- Security handling around manual auth routes was tightened

v0.0.21 keeps the momentum from the connector and desktop releases while strengthening the foundation: safer authentication, more reliable Docker behavior, and better server-owned chat state.
