131c043864 Fix loading of ImagePromptTemplate (#16868)
We didn't override the namespace of the ImagePromptTemplate, so it is
listed as being in langchain.schema

This updates the mapping to let the loader deserialize.

Alternatively, we could make a slight breaking change and update the
namespace of the ImagePromptTemplate since we haven't broadly
publicized/documented it yet..

a0ec045495 Add async methods to BaseStore (#16669)
- **Description:**

The BaseStore methods are currently blocking. Some implementations
(AstraDBStore, RedisStore) would benefit from having async methods.
Also once we have async methods for BaseStore, we can implement the
async `aembed_documents` in CacheBackedEmbeddings to cache the
embeddings asynchronously.

* adds async methods amget, amset, amedelete and ayield_keys to
BaseStore
  * implements the async methods for InMemoryStore
  * adds tests for InMemoryStore async methods

4ef0ed4ddc astream_events: Add version parameter while method is in beta (#16290)
Add a version parameter while the method is in beta phase.

The idea is to make it possible to minimize making breaking changes for users while we're iterating on schema.

Once the API is stable we can assign a default version requirement.
