# v2026.9.2

> Agent frameworks become optional dependencies, plus auth cleanup

## Slimmer Installs and Tidier Auth

If you only run your own custom handlers, you don't need Bindu to drag in agno, langchain, langgraph, ollama, and duckduckgo-search every time you `pip install`. This release moves all of those into an optional `[agents]` extra. The base install is now noticeably smaller; the example agents still work — you just opt in.

Also: a small auth-config cleanup. `/agent/negotiation` is now correctly a public endpoint, and several routes that never should have been on the auth-bypass list were removed.

***

## What Changed

### Optional Agent Frameworks

The heavy agent SDKs are now off the default install path:

```bash theme={null}
# Minimal — core Bindu only, for custom handlers
uv pip install bindu

# With the example-agent stack
uv pip install bindu[agents]

# Dev install
uv pip install -e ".[agents]"
```

The `[agents]` extra covers agno, langchain, langgraph, ollama, and duckduckgo-search. Blockchain and payment dependencies (x402, web3) are still in the base install — they're considered core.

### Public Endpoints Cleanup

`/agent/negotiation` joined the public endpoints list (it never needed auth and was previously gated). Static file routes and a few other paths were removed from the auth bypass list where they had no business sitting. The middleware config is now easier to audit.

***

## Migration

No breaking changes. Existing installs keep working.

If you use agno, langchain, langgraph, or ollama from your handler code, switch your dependency to `bindu[agents]` so the imports keep resolving. If you only call your own framework, the base install is enough.

## Release Process

The release workflow now uses week-based CalVer (`YYYY.W.D`). The create-release skill was updated to match.
