## Changes by Kind

### Deprecation

- Added a new `FileKeyRef` field to containers, allowing them to load variables from files by setting this field.
  

      this.delegate = checkNotNull(delegate);
    }

    @Override
    @ParametricNullness
    // We set the field only once (during construction or deserialization).
    @SuppressWarnings("SynchronizeOnNonFinalField")
    public T get() {
      // A 2-field variant of Double Checked Locking.
      if (!initialized) {
        synchronized (lock) {
          if (!initialized) {

To see all the options you have, checkout [Pydantic's Type Overview](https://docs.pydantic.dev/latest/concepts/types/). You will see some examples in the next chapter.

For example, as in the `Image` model we have a `url` field, we can declare it to be an instance of Pydantic's `HttpUrl` instead of a `str`:
