## Summary
Comprehensive post-v3.0.0 modernization: new features, bug fixes,
dependency cleanup, docs, and test coverage.
**New features:**
- **HTTP method filtering** — `@api.route("/data", methods=["GET"])`
- **Lifespan context manager** — modern async startup/shutdown
- **`api.exception_handler()`** — custom error handling per exception
type
- **`api.graphql()`** — one-liner GraphQL setup
- **`resp.file()`** — serve files from disk with auto content-type
- **before_request short-circuit** — set status code to skip route
handler
- **`req.path_params`** / **`req.client`** / **`req.is_json`** — new
request properties
- **`uuid`** and **`path`** route convertors
- **PEP 561 `py.typed`** marker
**Bug fixes:**
- Fix multipart parser losing headers
- Fix `url_for()` with typed params (`{id:int}`)
- Fix `resp.body` encoding crash on bytes content
- Fix Python 3.9 type syntax (`from __future__ import annotations`)
- Fix broken session test and no-op file upload test
- Fix helloworld example 404 on root path
**Dependencies:**
- Flattened — `pip install responder` gets everything
- Core: just starlette + uvicorn (down from 10 deps)
**Docs & README:**
- All new features documented in tour
- Modernized README features list
- Deployment guide: Docker, cloud, uvicorn
- Removed Pipenv, extras, stale references throughout
**Tests & quality:**
- 117 tests (up from 92), 91% coverage, 0 warnings
- CaseInsensitiveDict, GraphQL edge cases, staticfiles tests
- Ruff clean, all `tmpdir` → `tmp_path`
