chore: migrate to faststream 0.7 (drop <0.7 support)#4
Merged
Conversation
Bumps the dependency from "faststream>=0.5,<0.7" to "faststream>=0.7,<0.8".
Drops the _OLD_MIDDLEWARES runtime version-sniff entirely — single code
path, no compat shim, no <0.7 support. The package's version="0"
pre-release posture allows the hard break.
Changes:
- pyproject.toml: pin "faststream>=0.7,<0.8".
- modern_di_faststream/main.py:
- Remove "from importlib.metadata import version".
- Remove _OLD_MIDDLEWARES sniff and its <0.6 branch in
_DiMiddleware.faststream_context.
- Collapse the if/else property pair into a single property
returning self.context.
