### Fixes

* 🐛 Allow exit code for dependencies with `yield` to always execute, by removing capacity limiter for them, to e.g. allow closing DB connections without deadlocks. PR [#5122](https://github.com/tiangolo/fastapi/pull/5122) by [@adriangb](https://github.com/adriangb).

* Validate **complex structures**:
    * Use of hierarchical Pydantic models, Python `typing`’s `List` and `Dict`, etc.
    * And validators allow complex data schemas to be clearly and easily defined, checked and documented as JSON Schema.
    * You can have deeply **nested JSON** objects and have them all validated and annotated.
* **Extensible**:

#
# While the mount argument (`-v host_path:container_path`) still requires
# `container_path` to be a legitimate C:\ path, in this case, 'C:\drive_t',
# this symlink does allow for the convenience of passing unedited paths
# to `docker exec` commands, e.g., 'T:\path', instead of 'C:\path',
# without having to replace the drive letter with C:\ every time.

 *  Fix: Reject bad characters in the URL hostname. Previously characters like
    `\0` would cause a late crash when building the request.
 *  Fix: Allow interceptors to change the request method.
 *  Fix: Don’t use the request's `User-Agent` or `Proxy-Authorization` when
    connecting to an HTTPS server via an HTTP tunnel. The `Proxy-Authorization`

* GCI: Add two GCI specific metadata pairs ([#25105](https://github.com/kubernetes/kubernetes/pull/25105), [@andyzheng0831](https://github.com/andyzheng0831))
* Add an entry to the salt config to allow Debian jessie on GCE. ([#25123](https://github.com/kubernetes/kubernetes/pull/25123), [@jlewi](https://github.com/jlewi))
    * As with the existing Wheezy image on GCE, docker is expected to already be installed in the image.

Create a PassLib "context". This is what will be used to hash and verify passwords.

/// tip

The PassLib context also has functionality to use different hashing algorithms, including deprecated old ones only to allow verifying them, etc.

For example, you could use it to read and verify passwords generated by another system (like Django) but hash any new passwords with a different algorithm like Bcrypt.
