                      Merging `release` back to `master` is a regular operation you’re free to do, at any time. Usually, you will see conflicts in `notes.md` or `accepted-public-api-changes.json`.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference.

So you can come back and see exactly what you need.

## Run the code

All the code blocks can be copied and used directly (they are actually tested Python files).

	if !isXL2V1Format(e.metadata) {
		return false
	}
	if meta, _, err := isIndexedMetaV2(e.metadata); meta != nil {
		return meta.IsLatestDeleteMarker()
	} else if err != nil {
		return true
	}
	// Fall back...
	xlMeta, err := e.xlmeta()
	if err != nil || len(xlMeta.versions) == 0 {
		return true
	}
	return xlMeta.versions[0].header.Type == DeleteType
}

    * PR [#1862](https://github.com/tiangolo/fastapi/pull/1862).
* In `encoders.jsonable_encoder` remove parameter `sqlalchemy_safe`.
    * It was an early hack to allow returning SQLAlchemy models, but it was never documented, and the recommended way is using Pydantic's `orm_mode` as described in the tutorial: [SQL (Relational) Databases](https://fastapi.tiangolo.com/tutorial/sql-databases/).

You can type messages in the input box, and send them:

And your **FastAPI** application with WebSockets will respond back:

You can send (and receive) many messages:

And all of them will use the same WebSocket connection.
